Abstract
Systems and methods are provided for calibrating camera and measuring offsets for reducing distortions on images. The calibrating includes aligning an on-board image sensor and a lens barrel using a kinematic mount and affixing the onboard image sensor and the lens barrel to assemble a camera. The kinematic mount provides a predetermined number of degrees of freedom in aligning the on-board image sensor and the lens barrel. A device embeds the camera. The measuring includes receiving the camera in the kinematic mount and measuring an opposing pair of offset values as measured optical centers from the lens optical axis to the image sensor pointing reference at yaw orientations of the camera at 0 degree and 180 degrees. The method determines a total offset value by taking an average of the pair and canceling the rotationally symmetrical error. The method uses the offset value for reducing distortions on images by de-warping.
