Abstract: Aspects of the present disclosure include methods, apparatuses, and vehicles for performing intrinsic calibration of the cameras in the vehicle. A processor may acquire plural images of a target captured by the camera at different locations. For each image, the processor may tone map the image, binarize the tone-mapped image, define a structuring element based on the digital form of the shape of the target, perform morphology on the image to align and calibrate the structuring elements, filter the target and modify each of the other pixels to black, and compile an output image. Based on the calibration, the principal point values may be shifted to account for discrepancies and store calibrated values in each camera.
