Description

technical field

[0001] The invention relates to a three-axis orthographic pod for an unmanned aerial vehicle, which belongs to the technical field of photoelectric equipment in aircraft and aviation technology. Background technique

[0002] In the process of remote sensing aerial photography, remote sensing instruments are required to be as stable as possible, especially aerial photogrammetry, which requires that the heading overlap rate and side overlap rate are both greater than a certain value, which requires the camera to keep approximately vertical to the ground.

[0003] When the attitude angle changes greatly, the aerial photography images tend to have too low or no overlap, resulting in aerial photography loopholes, resulting in the unusable route image data with loopholes, and the aerial photography needs to be re-used.

[0004] Therefore, it is necessary to use a stable platform to compensate the attitude change of the flying platform to ensure the quality of camer...
