technical field

The invention relates to the technical field of unmanned aerial vehicles, in particular to a multi-angle variable three-dimensional modeling pan-tilt.

Background technique

Using oblique photogrammetry technology for 3D modeling has been applied in many industries. The more common solutions at this stage are roughly divided into two types: one is to place four cameras at a fixed angle (45-degree inclination to the ground). The ground is photographed at the same time, and the multi-angle photos of the ground surface are obtained to build a 3D model; the other is to rotate the two cameras to the ground and take pictures with a 45-degree tilt through the swing of the steering gear. Because the shortcomings of these two methods of shooting are the fixed shooting angle of the lens to the ground, and because 3D modeling requires multi-angle shooting of ground objects to obtain a better model effect, Gu designed a camera with a variable shooting angle to the ground. Gimbal to improve model quality.
