Satellite image connection point rapid acquisition method and system

The invention discloses a satellite image connection point rapid acquisition method and system, and belongs to the field of photogrammetry and remote sensing, and the method comprises the following steps: preprocessing a satellite stereo image pair, and obtaining a reduced left image and a reduced right image; performing uniform distribution optimization, single-piece texture optimization, three-dimensional texture optimization and consistency constraint optimization on the reduced left image and right image in sequence to obtain a plurality of optimized image block pairs; performing feature matching on the satellite stereoscopic image pair based on the position of each optimized image block pair to obtain a satellite image connection point; the system is arranged corresponding to the method and is used for realizing the method. According to the method, image block selection is converted into optimization of an energy function, and the problem of how to reliably extract high-resolution satellite image connect
