Determining other vehicle distances & collision warning (object detection) - Self Driving Cars p.18

[@legendarylucario211]

Hey sentdex, thank you for another amazing tutorial. In India today is called 'Teacher's day', this is the day we take time to appreciate and give our respects to anyone who has helped us gain knowledge. To me you are one of them, I just want to thank you for all the amazing context that you put up. It has certainly helped me a lot.

[@ThomasSMcNamara]

I am just getting into Python and really like it. Though everything you are doing is way over my head, I love it. It is inspiring and just really fun. Thanks for sharing this with us.

[@pottingmix3733]

Everyone starts somewhere as long as you don't give up you will be as good as anyone in python. Remember practice makes perfect :P

[@sundaresann4749]

Hi, i suggest to watch python3 tutorials @sentdex...even i learnt lot from it.

[@ThomasSMcNamara]

Very cool! Thank you for the suggestion, I will do that!

[@ThomasSMcNamara]

Thank you! I am really enjoying it.

[@arjunkrishna8873]

go through his machine learning with Python series kzbin.info/aero/PLQVvvaa0QuDfKTOs3Keq_kaG2P55YRn5v you could learn everything from scratch there

[@wolfisraging]

You are the best programmer I have ever seen, your videos are so much precious and unique, no one can find any such materials on KZbin, but you are such a n awesome man, I really appreciate your work, I love you, and I am learning a lot from you daily. Big fan😊

[@sentdex]

Thank you for the kind words :)

[@Davidnguyen-ck5bv]

just start tensorflow and machine learning in less than 6 months! guy like you who is willing to give free code guide help me alot!!! Greet from Vietnam and have a nice day!!

[@protodaishi6227]

I watched a handful of your tutorials a while ago but then kind of got out studying for a while. Starting to dip my toes back in and I think going back through some of the same stuff is a good start. It's really cool to check back and see you are still doing cool stuff. I'm glad you are doing something you love and you are doing a huge service to people. Thanks :)

[@chandrakantpattekar2465]

You are the best Sentdex! This video series employs many concepts of AI and I want to say a big thanks to you for bringing all this together. Eagerly awaiting your next tutorial video.

[@DisgracedCubFan]

This is the coolest thing I've ever seen.

[@sonusharma-uc7qb]

These tutorials are best in every way , it motivates and provide different aspects of using things , thank you for such a wonderful series

[@Mr8perezm]

I've been watching your zipline tutorials and came across this video. Very impressed, you're pushing python and general programming to the limit. Very inspiring video for newbies and kids.

[@digvijaysingh6332]

Thanks sentdex for spreading your knowledge. It really motivating me.

[@digvijaysingh6332]

Thanks for your quick response :)

[@sundaresann4749]

You're really helping me to develop my career...:);)

[@sentdex]

Awesome to hear!

[@alsdmaslm]

Same here! I'm currently preparing for a job interview that involves machine vision!

[@inimk]

Man you got a good memory power to hold that knowledge.. I learn so much stuff but can't apply even 10% of it..

[@maximkhanov4788]

I'm so happy that you post so often! Enjoy your videos keep up the good work!!

[@xuanzeng3426]

Like the way you keep coming up with interesting ideas in exploring the topic with us!! Thank you

Teaching robots to steal cars and run from police since 2017

[@sundaresann4749]

You're genius harry..Hats off to your work as i said you before, even kids can easily learn from you..true ;).. Thank you...::::))))

[@DavidChipman]

I like the fact that the image detection system thinks your speedometer is a clock! ;)

[@sentdex]

It's fairly close at least. I think the clock class could be renamed to "dial." I expect it was just trained on clocks, but it seems to detect any dial as a clock.

[@DavidChipman]

That's kinda what I thought. Just thought it was funny.

[@IsalaPiyarisi]

Dudeee !!! This is sooo freakin awesome please continue releasing tutorials like this

[@tobiea27]

Impressive stuff :D I think for better distance calculation, you should use the height or the area of the objects. The width of a car changes a lot if you rotate it. Maybe the box ratio will help you to detect if you see the side or the front/back.

[@novnod]

First time commenting on your video although I've been watching for the longest. Keep it up bro.

[@RaviPrakash_18]

All the classes of object that tensorflow can be seen in "models\object_detection\data\mscoco_label_map.pbtxt" file

[@poseidon4675]

AWESOME! I love this concept! I got into tensorflow myself too recently, but this is amazing!

[@AnshumanKumar007]

I'm building a facial recognition framework using facenet and Mxnet and i thought that was dope until I discovered your channel

[@creative.money_eu]

Man I love these videos thank you for this, makes me want to buy a new PC!

[@PureWaterSolutions]

This video is insane! Great work broski! 💻😎✌️

[@hakimke2]

Awesome! I have the same idea on how to do it (in theory) but do not know how to translate it into code. Love your video~

[@alokranjan5794]

@sentdex Could you please share your expertise how we can measure the distance of known object size from the camera. Suppose the dimension of the object is 50*50 mm then how the method you have shown could be utilized to compute the distance. Thank you for your excellent video to the community.

[@guardianpresencerobotics7776]

best thing for the road right now

[@suicidalbanananana]

Great video series man!

[@sushantsawant6703]

i need one help from you . do you know how to do distance detection with webcam and detected objects

[@__Beant__]

Absolutely love your videos, Sentdex. I'm currently studying robotics and building an object detection module for a soccer robot, your channel has been invaluable. In a real world environment, the focal length of the camera would also come into play. Would it be possible to let the AI learn with the distance information to improve object avoidance?

[@taufeqtauf1817]

So if our oject of interest is a car we can find the average pixel length of a (average)car at the closest distance and with respect to the area size of the detection box determine its nearness. If we use the same approach for a truck as well we can have a distinct comparison neasure for a car and a truck's distance which also differ in screen area and detection box area size. Although, neverltheless it doesnt seem to be a problem. The same approach can also be used to better judge pedestrian distances to set a safe distance. What do you think of this ?

[@rutujashah3910]

Hii sir, I am running this code on the spyder. so there is error in grabsceen which is already included in my library.so how can I remove this error?

[@gugasevero76]

Hi there! If I have a camera, pointing to diagonal of one street, showing/viewing cars parked, in a straight line, right? So, how can I meansure distances between cars? Thank you so much for your attention.

[@karkinissan]

For anyone else who can't find the file. The label file is in the "data" folder. It's called "mscoco_label_map.pbtxt". I was shouting at the screen.

[@FransHenskens]

AI learning algorithms are a chaotic system. They're very sensitive to input data. If you know the best way to filter out noise before applying one, you'll get surprisingly good results. Add an image scaling layer in the net for a few different zoom levels, applying it with an appropriate overlap (1/2 largest relevant object). If you can train these on a frame-by-frame basis for correct object detection (using obj location/width/angle logging) and pass that to a classical neural net (or SVM!) the output should be pretty great :) Or, if you can find think of sensible contrast functions between the output of these, using CNN would be better?

[@alokranjan5794]

Hey, Thanks for the great video and details. Just curious how you selected the size for different objects in your tutorial for distance estimation. You have chosen car=3 , truck=6 and bus= 8. Is this is related to the index in the .pbtxt file? Could you please share your suggestion, Suppose i know the dimension of the object then how can I estimate the distance from the camera or from my place? For example, a logo of a company sign is having 50 mm diameter then how to know the distance from my standing place? How can i translate the index (in your video say 0.2) into meters?

[@sankalpsahu2154]

the code is running but it's not showing the video on the screen the cv2.imshow('window', screen).

[@balajichetty305]

Hi Sentdex, your tutorials are awesome. Can you describe, and help me to figure out how to control the drawing of bounding boxes only for certain classes? Thanks

[@Zhak7]

You sould probably take into account the current speed of the vehicle your character is driving and also the rear lights of other cars. You could then predict when to slow down and even stop before hitting any car at all

[@fatihelibol58]

Hey, please help me. How can I print the found objects on the console?

[@pringlesss7701]

at 3:05 it's : [y_min, x_min, y_max, x_max]

[@projectwork4568]

Any V2V or V2X video you uploading in coming days?

[@abir9233]

Thank you for the amazing Tutorial ! i just have a question can we replace screen grabbing by an MP4 video?

[@tuhinmukherjee8141]

Yes ofc, any video stream would work as it's just extracting pictures frame by frame.

[@milaandahiya]

What OS are you running? And if you are running Ubuntu do you use Wine to run GTA? Or do you dual boot with Windows?

[@sentdex]

100% is happening in Windows.

[@illank86]

can you use tensorflow to detect traffic, if its jammed or not? could you create tutorial for that... i have following the tutotrial till this video, but has no idea how to implement it to check the traffic

[@vicveesi]

What are the index that he used in "classes[0][i]". Where can I learn a theory about it?

[@malotabi5949]

thisis amazing can we consier the warning as an attack?

[@shivrajkumar8914]

i did tensorflow realtime object detection and its working fine for custom dataset by looking your videos, now i want to try please tell me how can we get that video and where u will store that video in object detection folder

[@Jakeh077]

Hi sentdex, do you happen to know the units that the distance output is in, or how to get it into meters? Thanks and i really enjoy watching your videos!

[@sentdex]

well, it's just approximate. I wrote it. I forget which unit of measure I was using. I just eye-balled it. The scale isn't perfect tho. It's just all based on how wide the car is in pixels. You're probably better off just using the raw number, rather than doing some conversion, but I liked the idea of converting it to something reasonably close to feet or meters.

[@Jakeh077]

Ah ok gotcha. Thanks for the fast reply! Also just wanted to say thanks for your videos. I’m a biomedical engineering student and for my senior design project we are making a navigation assistant for the visually impaired. And we have used several of your tutorials to help learn about tensorflow for our project!

[@codetech6099]

Hey there i am watching your video series from a month and getting knowledge about python programming.(i have subscribed your channel). My question is that Can you suggest some books for python programming?

[@HarshSingh-np3ts]

Hey sentdex, Can you help me with increasing the processing speed of the frames or on what factors does the processing (marking objects,warnings etc.) depends on? And thanks your videos are great :)

[@kasunhewagama6453]

In the code, you take car == 3, bus == 6, and truck == 8. from where did you take that measure? How did you do that? any logic?

[@vismayamenon1719]

Is it possible to apply this method on any other object detection problem ? for example person distances and collision warning ?

[@luthontantiso7747]

how do you only detect cars in image or video with detecting other objects?

[@lokilocus7620]

could u make a video series about writing lexers, parsers etc for creating a programming language?

[@jayakumarj7173]

Is it Possible to implement this idea to real life....?

[@default632]

Yes. But it'll be much more expensive to test and train.

[@durgaprasadreddy5448]

hey sentdex can we do this for autonomous navigation of drones???

[@nate0031]

What kind of hardware is needed to run tensorflow like this?

[@mehranali3310]

is that same work for the object detection and distance from camera to objects

[@muhammadazmizainudin4624]

is it possible to get the speed of vehicle approaching you since you already know the distance of the vehicle?

[@ahmadrashed1672]

many thanks to you keep going

[@MSalman1]

Just amazing work Harrison! Any suggestions for people who cant use GTA due to hardware requirements?

[@sentdex]

Try san andreas. No idea i fit works, but I suspect it would.

[@arjunkrishna8873]

few of us did a project on nfs last year using similar methods you can try that

[@guruvishnu11]

Hi Sentdex, Thanks a lot for a Superb Idea and Code, Can you please let me know, if there is any chance of adding an mp4 file as input, instead of screen grab?

[@StrawHatLuffy750]

use cv2.videocapture() .could be done with opencv.

[@sumitpatnaik7057]

Can I use tensorflow lite in raspberry pi

[@amitjajoo9510]

can u explain which distance is this

[@prabhu0225]

First of all thank you soo much for all this video ..I would like to do a project like ..finding the object and finding the object distance from the camera ..could you please tell me ??how I can

[@alexboitor5699]

does somebody know how to block tensorflow from detecting certain objects with this model? i mean, i want to use this model, but i don't need cats, dogs, or potted plants for example (and i would guess removing items would speed up the processing). I watched the tutorial series to create a custom model, but i'm curious if i could remove some items from this one. Thanks in advance!! P.S @sentdex you're the best!

[@garceling]

Can I used the same code in real footage on the road

[@WorldWithAravind]

how do if check the distance between two object

[@nadarbzh]

Im really intrested in self driving car and it would be cool if you could train a model that drives like a real self driving car. Maybe from point a to b via maps if and following the rules as good as possible;)

[@sentdex]

Charles drives point to point already www.twitch.tv/sentdex ... but he doesn't follow rules. Working currently on a way to get a few versions of charles, one that does try to follow rules, but we'll see.

[@nadarbzh]

Thanks for the answer. I've seen the navigation via maps but it would be super cool to see it in combination with following rules and how good this model would work compared to the big players like waymo ;) Btw love your tutorials!

[@raghuprakashreddy1794]

Please share the link for dowloading the sample gameplay

[@alexanderparker1992]

Would it be possible to use this to make additional training data for your original self driving implementation and improve it?

[@fleecemaster]

I'm pretty sure that his plan is to integrate it, which I'm very excited about :)

[@CreativeShorts75]

Is this a self driving car ,I mean does it move automaticallly?

[@ahmadmaher5326]

Bro , How we can crop objects from a video based on scores . Is this possible?

[@Salman-xz4km]

Hey !!! I just want to know can we use this API to train our model in realistic environment like GTA V instead of programming our own customize objection code of every different game or environment ... So that we can make our Ai more generalized (some algorithm of different games).... Thanks in advance

[@vishavsingh3717]

How much Fps are you getting and can your algorithm works for detecting an obstacle at about 10m away from car

[@Jayjlow]

How much of an impact (frame rate and detection wise) would it be if you detected every 3rd or 5th frame instead of every frame?

[@sentdex]

It seems to me to make more sense to just allocate as much vram as you want to the app, and let it maximize that. It's already not doing every frame.

[@JohnDoe-kr9zh]

your the man!

[@thrupthirrai9309]

i did not get any error nor i dint get any output .. please help me

[@clinton11994]

Hi . What minimum system configuration do you suggest for deep learning ?

[@sentdex]

8GB of vram NVIDIA GPU, 16GB+ RAM. i7 processor, or you can use a cloud provider for the DL training. I've been using paperspace on the side when my GPUs are occupied. I covered them here: kzbin.info/www/bejne/boOtiWuNg8iLr6s

[@pottingmix3733]

I use a gtx 750 ti to run the models and was using google cloud for training but paper space is better :P
