Update:
Sorry for the late reply. Hope the following information can help you:
1. If you are using a Zenmuse P1 camera, you can refer to the Timestamps.MRK file generated by the camera. There are fourth, fifth and sixth lines in it, which represent the compensation value from the camera to the antenna position. You can fill in this value for PPK;
The fourth column: the deviation of the antenna phase center to the camera CMOS sensor center in the north direction (N) at the moment of exposure of each photo, the unit is mm, the CMOS center is positive in the north direction of the antenna phase center, and negative in the south direction.
The fifth column: the deviation of the antenna phase center to the camera CMOS sensor center in the east direction (E) at the moment of exposure of each photo, the unit is mm, the CMOS center is positive in the east direction of the antenna phase center, and negative in the west direction.
The sixth column: the deviation of the antenna phase center to the camera CMOS sensor center in the vertical direction (V) at the moment of exposure of each photo, the unit is mm, the CMOS center is positive when the antenna phase center is below, and negative when it is above.
2. If you want to measure manually, please refer to the following information: The main antenna is the center of the RTK antenna mushroom head of the aircraft's No. 4 arm, and the compensation value data (the center position of the gimbal interface of a single gimbal is relative to the position of the No. 4 RTK antenna) ):
X-axis direction: 443.37mm
Y-axis direction: 333.63mm
Z-axis direction: 91.13mm |
