I’m developing a 3d pose estimation software for sports, and given an athlete (almost static) I would like to put 4 cameras around him to be able to provide inmediate feedback using an screen and to run some opencv pose estimation, and record the 4 simultaneous and synched feeds.
I would need fullhd / 30fps on each camera full color, and each of the camera will need to be about 1-2 meters far from the main control.
I was thinking on using the camarray + some arducam hdmi extensors + 4 cameras, and here is where I don’t know (if) and which arducam cameras could be used. Also I noticed that you don’t provide the camarray hat alone so I would like to know what is the best way to get the needed hardware.
I was thinking on a raspi4 as I’m more used to them and I already have a lot of raspis (I have been collecting / using them since the first one). But I’m open to use a jetson or whatever is better.
Also, the raspi foundation has just released the compute module 4 that looks very promising, and the form factor is not bad for what I have in mind.
My idea is to do be able to show the 4 frames of the video on realtime for the athlete, and run a pose analysis using opencv also on realtime, so with some parameters it can show direct feedback (this kind of exercise is being done using a mirror, so that is my starting point)
We have not tested 4 1080p 30fps on the Pi4 platform. According to our experience, Using our 4-1 hat. it can run less than 30fps due to the comprehensive receiving performance of pi4. On jetson board it will be better.
Thanks for the information. As I already have some pi4, I don’t mind reducing the resolution at the early stages and if needed switch to a jetson system.
So, given that which cameras / camarray should I pick?
Are you going to sell a 4 cameras kit with more resolution and not only monochrome?
Ok then, thank you for the update and the good work
I will wait until you release the new kit.
I already have been following you waiting for the camarray, but I didn’t see any post regarding the actual release of the camarray, I noticed it searching directly.
What I mean is that we will release a 4-1 full color high frame rate board on Pi platform recently. But we have not used the camarray. I am willing to study with you about the camarray.
Have you already released the 4-1 high frame rate board ? if yes, can you point me to the resource on your web so I can review?
What do you mean with “not used the camarray. I am willing to stody with you about the camarray”?
If I can buy a camarray and several full color cameras that could work I can make the tests, but as far as I know there is no way to buy the camarray without a kit and also the firmware should be adjusted to each use case. Am I wrong?
I have read the camarray introductory post and I hope you can release the new kit with your own library soon (it would be perfect for xmas )
One question, in my proyect I would need to set the cameras about 1-2 meters away of the control unit. What should be the best aproach?. Use long flat connections? or add 4 hdmi conversos so I can use hdmi cables as extensions? Would the performance affected?
