Evaluation method and evaluation device for internal reference calibration, electronic equipment and storage medium

The embodiment of the invention provides an evaluation method and evaluation device for internal reference calibration, electronic equipment and a storage medium. The method comprises the following steps: acquiring a plurality of calibration images from different visual angles; calibrating the plurality of calibration images to obtain internal parameters of the camera; generating a target image based on the plurality of calibration images, wherein feature points of the target image comprise calibration feature points of each calibration image; calculating a feature point coverage rate, a global re-projection error and a local re-projection error of the feature points; and evaluating the internal reference of the camera based on the feature point coverage rate, the global re-projection error and the local re-projection error. According to the embodiment of the invention, multiple evaluation indexes such as the feature point coverage rate, the global re-projection error and the local re-projection error are ado
