Photoelectric radar target detection method and system based on Beidou

The invention discloses a photoelectric radar target detection method and system based on Beidou and belongs to the field of photoelectric radar. The method and system mainly solve the problems about the position (distance and location), the speed, the time and the like of a detected target. The method includes the implementation steps that the geodetic coordinates of a photoelectric detection system are obtained through a Beidou satellite navigation system; the pixel coordinates of the target and the pixel coordinates of a background point of the target are obtained through the photoelectric detection system; the known geodetic coordinates of the background point in a database are called. With the photoelectric radar target detection method based on Beidou, the three-dimensional spatial posture of the imaging face of the photoelectric detection system can be determined through space resection, the geodetic coordinates of the target can be obtained through space intersection, the speed of the target is obtain
