Zusammenfassung:The invention relates to a multi-view-angle satellite image block adjustment method and system, and the method comprises the following steps: S1, obtaining an original satellite image shot based on multiple view angles and additional original RPC parameters, and obtaining the coordinates of connection points from the original multi-view-angle satellite image, the connection points comprising control points; s2, an error equation Vxy and an error equation VC are listed for each connection point on each satellite image, # imgabs0 # imgabs1 # imgabs2 #, and Vxy is used for measuring a distance residual error between a back projection point after adjustment and an original image point; vC represents the residual error between the adjusted RFM optimization result and the initial value of the RPC parameter; and S3, solving the error equations Vxy and VC in a normalized manner by adopting a least square adjustment thought to obtain optimized RPC parameters. According to the method, an additional model is not introdu
