Empty three encryption precision which is high

Air three encryption accuracy X and Y high. According to the query related information,

1, for artificial structures in dense areas of stereo image, the number of feature points is dense, air three encryption precision tilted image checkpoints precision compared to the downward looking image precision is high. The resolution of the image is 10 centimeters.

2, the measurement results of the plane x, y error are in the precision range, the elevation of the z-value error is slightly larger. After increasing the number of control points, the accuracy of plane x and y is significantly improved.
