New CM3 Flash - not detecting one camera

I have been using StereoPi v0.9. I have a perfectly working setup, that both cameras are detected. When I went to replicate the same set up with another StereoPi v0.9, and with two different boards, the left ribbon cable port is not detecting a camera. The same cameras are properly detected in my or...

Re: Right Camera Calibration Issues

Thank you! I actually caught this same error shortly after posting my issue. It is now fixed!

I am still not getting a well-defined disparity map though. My maps are all very noisy, there is no clear shapes even for a basic picture of a box against a blank wall.

Right Camera Calibration Issues

I'm using the stereopi set up, and created my own script using opencv for calibration. The chessboard corners are detected very well in the left camera images each time, but the right camera images struggle to correctly identify chessboard corners. Below is the link to my github with the code. I hav...

Re: Splitting stereo video into two videos?

Hi Realizator, I'm trying to create 3D models in agisoft from collected stereovideo, and I'm unsure if I can directly input stereo video into the software, or if I need to input frames from each camera. I am also looking into how to give it my calibration camera info to get accurately sized models. ...

Splitting stereo video into two videos?

Hi, I'm hoping to be able to split my recorded split screen video into a left and right video so that I can make a disparity map video from them. Is this possible? How would I go about doing this?

Re: picamera.exc.PiCameraMMALError: Failed to enable connection: Out of resources

When I change the line: camera = PiCamera(stereo_mode='side-by-side',stereo_decimate=False) to only be camera = PiCamera() I am able to get a video stream but I think it is only for one camera. I also tried: camera = PiCamera() camera.stereo_mode='side-by-side' camera.stereo_decimate=False but both ...

picamera.exc.PiCameraMMALError: Failed to enable connection: Out of resources

I am trying to run the stereopi tutorial code 1_test.py. After running vcgencmd get_camera I get supported=2 detected=2, and I enabled cameras in raspi-config. I also ran sudo apt update and sudo apt upgrade and checked to make sure no other programs are using the camera. This error happens when I r...

Cameras supported=0 detected=0

I am getting supported=0 detected=0 when running vcgencmd get_camera even though I put the dt-blob.bin file into my boot folder during initial configuration and enabled cameras through raspi-config. What other steps could I take to fix this issue?
