Camera preset bit correction method, device, equipment and medium

The invention discloses a camera preset bit correction method, device and equipment and a medium, and relates to the technical field of camera application. The preset bit correction method comprises the following steps: extracting a feature point set of a detection image, matching the feature point set with a feature point set of a reference image to obtain feature point set pairs, and correcting the preset bit of the camera based on the number of the first feature point set pairs. According to the method, the difference condition of the number is distinguished and corrected through the feature point set, and the problem that correction fails when the difference between the shooting positions or the focal lengths of the reference image and the detection image is too large in a traditional correction method is solved. 本发明公开了一种摄像机预置位校正方法、装置、设备及介质，涉及摄像应用技术领域。该预置位校正方法包括：提取检测图的特征点集，将其与基准图的特征点集匹配，得到特征点集对，基于第一特征点集对的数量进行摄像机预置位的校正处理。本发明通过特征点集对数量的差异情况进行区别校正处理，解决传统校正方法在基准图与检测图的拍摄位置或焦距差异过大时存在校正失效的问题。
