Three-dimensional coordinate measurement method and system based on airborne photoelectric platform

The invention relates to the field of photoelectric measurement, in particular to a three-dimensional coordinate measurement method and system based on an airborne photoelectric platform, and the method comprises the steps: completing the calibration based on a high-speed camera, determining the internal reference of the camera, and obtaining and storing image information in real time based on the high-speed camera carried by an unmanned plane photoelectric pod; determining moving target information through logical operation based on the image information; acquiring image information of the target in the high-speed camera based on the determined moving target information, extracting feature points, determining the reliability of the feature points based on the distance between the feature points, and executing a feature point matching strategy based on the reliability of the feature points to determine correct matching feature point pairs; based on the correct matching feature point pairs, final matching feat
