WebCamera parameters include intrinsics, extrinsics, and distortion coefficients. To estimate the camera parameters, you need to have 3-D world points and their corresponding 2-D image points. You can get these correspondences using multiple images of a calibration pattern, such as a checkerboard. WebStereo Calibration Process. To calibrate a stereo camera, you can simply run the command: voxl-calibrate-camera stereo, open the web portal, and fill the rectangles like such: The stereo calibrator calculates the intrinsics for each camera separately, so you will need to fill in all of the left rectangles, then all of the right rectangles. gameboy advance tv episodes cartridge
