| Abstract: | When remote sensing,the change of the aircraft's attitude data(roll,pitch, yaw), height, speed and the property of sensor itself causes the geometric distortions of image pixels relative to surface objects. A geometric correction model of tri CCD line sensor imaging is established by use of outer orientation elements synchronously recorded by IMU and inner orientation elements calibrated in the lab. At last geometric distortions and geometric corrections are simulated on the computer. |
