Everytime I see the video u uploaded, I am excited cuz all these progresses are impressive and promising.

[@NicolaiAI]

So awesome to read! Glad u like them and u made my day 💪

[@hviiid91]

This is very interesting.. again thanks for the video! Looking forward to some potential content on runtime performance with this

[@NicolaiAI]

For sure very interesting and unlocks a bunch of new opportunities in the vision space

Hi Nicolai! I just want to ask that how can I estimate the depth of an object as well as its classification.

[@isura3147]

Hey Nicolai , I get an error "No module named 'depth_pro' Any idea of how to resolve this issue ? i checked the folder structure and everything seems to be exactly as you have in your video. thank you !

[@AmnaBano-kd7ex]

hey just place your main file in the ml-depth-pro-main\src\depth_pro folder that will do

[@isura3147]

@@AmnaBano-kd7ex Thank you it worked! I appreciate it !

The focal length is read from exif info of the image (in mm) and then converted in the code to pixel values (utils has a function for it). When I print out the value of f_px, it is always None for all images. How is the model getting focal information. Also all the pictures that I use, the depth information is often wrong.

[@twishakhurana7618]

is it necessary that the image must be of high resolution?

[@interestingfacts1466]

How much time does the code take to run fully? Does it take much time?

[@NazaninPadkan]

Thank you for the nice video. Did you also check the 3d reconstruction using open3d? Whenever I use an estimated depth from a metric MDE algorithm to generate a point cloud, I can not get a right size of objects

[@NicolaiAI]

Most likely because of the focal length and cam params being off. Have u tested out the new one here which also gives u the focal length? Then u can set the optical center to half of img height and half of width

[@NazaninPadkan]

@@NicolaiAI Thanks for your answer. I have calibrated my camera and I have my own parameters. I have just found your new video, but I already tested Metric3D v2 and Anything Depth. But unfortunately I got need measurements in 3D and the sizes are not correct

[@NicolaiAI]

@NazaninPadkan the depth map is not based on your camera parameters but just an output from the ai model. So that might be one of the reasons

[@NazaninPadkan]

What is your suggestion here?

[@Skrewex]

The video is pretty quiet compared to other videos and ads on KZbin, maybe bump up the volume a bit?

[@NicolaiAI]

Yeah missed that in this one! Thanks for letting me know

[@Skrewex]

No problem, thanks for the great videos!

[@Rahi404]

What's the VRAM usage of this Apple Model?

[@NicolaiAI]

Ran out out mem a couple of times on 16gb while recoding and bunch of stuff open. Prob around 10gb

[@Rahi404]

@@NicolaiAI then I've to find a new way to measure the distance with depth map

[@kemmunvlogs7388]

Can it be used with IDS camera, man?

[@NicolaiAI]

Yes as long as u can extract the frames and throw them through the model

[@insideyourbrain2333]

it is posiible to implement this code in a Intel realsense camera or doing this with other versions of yolo like yolov3?

[@NicolaiAI]

Not sure why u would use a realsense camera with this but yeah u can use any other object detection models or any algorithm to index the depth map

[@abophotato]

Good one, I hace seen your old video says c++ is faster than python but why this video is using python 🤔 btw may I ask what's your gpu are using now and it's c++ and python's fps?

[@koufdell]

peace nicolai , i used the model with a mobile rtx 3050ti and it takes ages,any suggestions?

[@NicolaiAI]

Hmm might be because of ram. But did take 20 seconds on my MacBook cpu. Will have to test it on colab or my own gpu

[@koufdell]

@@NicolaiAI well i used fp16 precision and ,while it took some time, it was faster TLDR:the create_model_and_transforms has an argument precision) thx for the reply,awesome content

[@NicolaiAI]

@koufdell thanks a lot!

[@guilhermegouveialopes7170]

hi everyone, i tried using this for a project, did everything like the video. The thing is, it is way too slow. I noticed that the "model.infer(image_input, f_px=f_px)" takes about 60 seconds to run. Is there any workaround for this? Thank you for reading

[@isura3147]

Yeah , i had the same issue, if you find a solution please do let me know as well . Thanks !

[@sandeepwadhwa531]

Same issue for me. The command does take about 4-5 minutes on Mac Book Air, 8GB.

[@guilhermegouveialopes7170]

@@isura3147maybe try other model. I heard that depthanything is much faster
