Re: Depth map calibration/explanation

Re: Depth map calibration/explanation

hello Realizator, Can you help me check the code "4_calibration_fisheye.py" for my images? I do not know what happens when I received an error " (-3 internal error) calib_check_cond - ill-conditioned matrix for input array 35 in function 'cv::internal::calibrate extrinsic'". I used the latest code i...

Re: Capture still images from HQ Camera 12.3MP

hi Realizator,

It finally works for me and I should accept that the average FPS is very low (~1.5 FPS with 2688x1024).
Thank you so much for your support.

Re: Capture still images from HQ Camera 12.3MP

hi stereomaton, I have already followed the rule for width and height values. For example width = 2592, height = 976, and the vertical stripes began to appear. But it is fine for a resolution of 2560x960 or less. I expect to get a minimum resolution of 2688x1024 but it did not work. I hope to receiv...

Re: Capture still images from HQ Camera 12.3MP

Hi Realizator, I really want to receive your help with another problem. I tried to capture stereo images with a resolution of greater than 2560x960 but it did not work well.

Re: Capture still images from HQ Camera 12.3MP

Hello Realizator, I think my issues here are a bit different from the previous topic. Even though I tried with resolution 2028x1128 (or whatever), I got an error like this: File "/usr/lib/python3/dist-packages/picamera/camera.py", line 123, in capture, 'Timed out waiting for capture to end' picamera...
