[Elphel-support] mono video output postprocessing

Hello, Now we use our stereo camera in mono mode, so the resulted 8bit grayscale video's pixels corresponds to the color value of the CCD in G G R B layout - if I'm right. I'm just wondering: Is there any easy way (preferably in Linux) to convert this format into a video of half size, half wid

[Elphel-support] thermal correction

Hello, We are calibrating our stereo camera indoor in 25 C, and using it outside in a car, where I guess the temperature can go up to 40 C especially in the black camera case. Is this thermal change requires a recalibration or the lenses (353-70-50) are stable enough against such a temperatur

Hello, I'm playing with an elphel NC353L stereo camera. By now registering, streaming works fine, but when I put the images into my (otherwise properly working) depth/disparity algorithm it gives really nonsense results. I guess this is because the images has to undistorted and rectified in adv
