System for correcting geometry of mobile platform with sensor based on an orthophoto

摘要

Provided is a geometric correction system of a mobile platform equipped with a sensor based on an orthoimage. The geometric correction system of the present invention comprises: a sensor unit including at least one of an image sensor, a navigation sensor, and a three-dimensional measurement sensor for obtaining three-dimensional geographic data; a similarity analysis unit for analyzing the similarity between observation-related data obtained from at least one of the sensors equipped in a mobile platform and orthoimage-related data having two-dimensional geographic information, and setting reference data estimated as the same from the observation-related data and the orthoimage-related data; a network model configuring unit for generating a geometric model between the reference data and the observation-related data on the basis of the reference data and a reference coordinate system of the orthoimage; and a most probable value calculating unit for calculating a most probable value for minimizing the amount of difference between the observation-related data and the reference data from the geometric model, and generating corrected data estimated from the observation-related data in accordance with the most probable value. According to the present invention, the accuracy and stability of three-dimensional geometric information correction of a mobile platform are secured.
