System and method for image navigation and registration of satellites

摘要

The present invention relates to a satellite image geometry correction system and a method therefor, and more particularly, by receiving image data observed from a satellite, setting it as reference image data, and recognizing a cloud pattern included in the reference image data to create a cloud A cloud detection unit 100 for generating a mark and converting the generated cloud mark into a database, a geometric correction unit 200 for receiving image data observed from a satellite, and performing geometric correction by applying a preset algorithm ) and the accuracy of the geometric correction performed by the geometric correction unit 200 is determined, and when the accuracy is lower than the preset reference value, the geometric correction is repeated using the cloud mark generated by the cloud detection unit 100 . It relates to a satellite image geometric correction system, characterized in that it comprises an additional geometric correction unit 300 to perform.
