Abstract
Techniques for calibrating a camera utilizing a calibration station. The camera calibration station may be configured to emit collimated light toward a camera housed in a cradle. The camera may capture images of the collimated light at pre-determined positions throughout a calibration sequence. A computing system associated with the camera calibration station may utilize reference locations determined based on the collimated light at the pre-determined positions compared to measured locations of the collimated light at the pre-determined positions to determine intrinsics of the camera (e.g., focal length of lens, optical center of lens, etc.) and an error associated therewith. Based at least in part on the error being less than a threshold error, the computing system may store the intrinsic parameters of the camera.
