Vertical Stripe when at 1080 resolution

Hi has anyone seen this vertical stripe issue before. I am using waveshare I camera modules and at 1920x1080 resolution. If i reduce resolution to 720 I dont see the issue
Any ideas whats causing this?

Re: A physical button to take photos

Hi all,

I have been reading this forum post and it is exactly something I am looking to do. One question is the button connect through a breadboard, or straight onto the GPIO pins using the stereopi power connector?

Thanks

Re: Stereo_Camera Calibration error

I have fixed my stereo calibration camera issue. It seems i had a few bad stereo pairs, using the example mentioned here and the fix I was able to solve it: https://answers.opencv.org/question/213931/assertion-failed-abs_max-threshold-in-function-stereocalibrate/ Adding this code to calibration afte...

Re: Stereo_Camera Calibration error

Hi, Sorry for long reply been away, and its been chaotic with current situation. I now have some time and really want to solve this. One thought i had with why you cant detect checkerboards is i used a 8x6 checkerboard. Sorry i should have mentioned this before. I have tried again, with a bigger 8x6...

Re: Stereo_Camera Calibration error

Thank you for the tips. I will take these on board and try again.

I find it strange though when I ran the code it claims to detect checkerboard and successfully calibrate both left and right camera just not stereo.

Thanks again I will try this again.

Re: Left and Right Cameras Reversed

I managed to do the swapping, by putting cameras other way up and then Hflip and Vflip.

However if i wanted to change primary camera in the PiCamera library would this be a raspistill -cs1 switch in the bin file?

Re: Stereo_Camera Calibration error

Hi

I fixed the swapped images, and tried the halving technique, still no success as when i decrease number of photos it claims bad matrix's.

Do you have a place where i can send photo sets?

thanks

Ben

Stereo_Camera Calibration error

Hi, I am running the Stereo Pi Fisheye tutorial. I am on part 4, the calibration. I seem to calibrate both individual cameras but it fails on the Stereo calibration. File "4_calibration_fisheye.py", line 170, in calibrate_one_camera result = calibrate_one_camera(objpointsRIght, imgpointsRight, 'righ...

Re: StereoPi AnyCase Kit

Hi, I have purchased the anycase kit, i have the waveshare RPi I fisheye camera (https://www.waveshare.com/wiki/RPi_Camera_(I)) This camera does not fit with the anycase kit I purchased, even though it states it works for waveshare. Has waveshare updated their camera modules? I am very frustrated as...

Re: Left and Right Cameras Reversed

I have the same issue, however with a Rasbian image. Is there a solution using the Rasbian image?
