Raspberry Pi Backup Camera - ECE 470 Clemson

[@JoshGerhards]

The camera angle definitely needs to be adjusted there...

so he directly connected 12v to gpio .. probably to fry rpi... I personaly think its not good solution to use wifi camera because image can freeze or not show in the real time.. better to use camera and compostite output and watch it in real time. by just wraping the wire around pin , and using 12v directly .. its like beginner with electronics

[@ElectricMilesLLC]

I see that the voltage is 11 volts for the reverse light signal. Were you able to tap into that and send it straight to the board? I thought the max input voltage on a raspberry pi gpio was 3.3v.

It's a nice idea. But there are still a couple of practical problems: .) In my opinion, the video stream shouldn't be send via Wifi. It would be better to buy a monitor and connect it with the raspberry (hdmi or the port). There always latency issues with streaming via wifi and you need at least one another device (Ipad, or whatever) to watch it. .) Instead of a USB cam, there are another cameras (smaller, water-resistent, ...), which delivers just the raw video data. This could be connected to the GPIO pins, so you could use a longer cable. (If the monitor and the raspberry are for example somewhere in the glove compartment, the camera could be connected with a cable from the back of the car to the raspberry. .) In many cases, you just need the reverse cam at the beginning and the end of your ride. I'm not sure, but it could take a long time to boot and initialize the cam after you start the engine, so you have to wait maybe 30 seconds, that's quite long. On the other side, the costs will raise, if you need to buy a good monitor (~50€) and a camera (~30€). The reverse camera is such practical and good thing, I have it on my Nissan Quashqai and I wouldn't buy a new car without such a cam ;-) - Therefore I was motivated to find a solution for cars without a reverse camera, but then I faced the problems, which I described on the top.

Thanks for the feedback, folks! Obviously there are a number of ways this implementation could have been improved and you have covered the main ones. My favorite part of this project was that I didn't have to buy ANYTHING to implement it. I had the pi, the camera, the iPad, and all the cables in various places around my room. I call it the "Apollo 13" approach to problem solving

[@brendanssound]

This is exactly what iv been looking for. Could you tell me which camera you used and do you experience any latency issues with having a 4 or so meter cable between the camera and Pi. Also any further details on how exactly you looked up the reverse would be great

[@nsamadisy]

Hi, I'm working on something similar.Could you please share the code you used specifically for letting your Pi sense the when the reverse lights turn on, then turn on the video stream from the camera? ( the wire you have connected to the GPIO pin) I'll be using a Pi camera, but other than that the concept will be the same.Thanks!

[@luketc1]

I tried to find the code just now and unfortunately I don't have it anymore! The Mac I was using to write the code / SSH at the time fell victim to a bottle of beer in its keyboard :(

[@nsamadisy]

Don't know what I feel worse about - the lost beer or the lost code...8)

[@luketc1]

I can tell you I definitely feel worst about the dead Macbook Pro

[@zinussan5994]

Hi, im planning to do media center for my car using raspberry pi. Initial plan is using kodi as main image, so if i want to add camera as backup camera for my car, can i switch from kodi to camera?

[@luketc1]

+Zinus San you will have a different setup, likely with the raspberry pi powering your display and a wired camera. If you're trying to use Kodi you will likely be running on some version of Debian Linux, so you will just need to either tie into your vehicle's reverse light like I did, or add a shortcut to switch between your camera program's GUI and Kodi

Stay inspired! Also excellent choice of music ;) #pharcyde

[@Jsjaja-b7u]

hey what are you using to stream the live video to your ipad?

[@sudharshanvenkatesh7893]

How is the delay?

[@luketc1]

I would've liked to see a little lower latency. I'd imagine the source of the delay was MJPG-streamer combined with the relatively low processing power of the Raspberry Pi. I'm not sure what kind of camera or video encoder I would have bought instead for better performance, but luckily for this project I already had everything I used :)

Go tigers!

[@aojathotmail]

thanks I was looking for something like this. But I think I'm going to use a wide-angle lens
