[0051] The present invention provides a combined adjustment method of laser ranging-assisted optical image, which is suitable for a reconnaissance measurement platform that provides optical images and laser ranging devices. The optical image is used for target observation and tracking, and the laser ranging device is used for measurement. The distance from the platform to the target area is mainly used for the acquisition of image outer bearing elements without direct ground control information and high-precision target positioning. Practical applications show that some reconnaissance platforms are equipped with such measuring devices. In reconnaissance missions, the target area is usually far away from the observation platform, the optical image is shot at a large angle, and the observation range of the target area is limited. It is impossible to provide ground control points at any time during the mission, so the laser ranging value becomes the only control method. In the fie...
