Description

Technical Field

[0001] The invention relates to the technical field of three-dimensional oblique photogrammetry, in particular to an automatic rotation device for three-dimensional oblique photogrammetry. Background Art

[0002] A 3D model is a polygonal representation of an object, usually displayed by a computer or other video device. The displayed object can be a real-world entity or a fictional object. Anything that exists in the physical world can be represented by a 3D model.

[0003] When deploying the camera, it relies on a placement frame for basic support. However, the function of the traditional placement frame is limited to horizontal fixation. It cannot flexibly adjust the tilt and rotation angle of the camera, which limits the diversity of its shooting angle. To solve this problem, advanced devices that can control cameras in three dimensions have emerged on the market. These devices cleverly use multiple independent motors to provide precise power support in multiple dimensions such as vertical, horizontal and tilt, allowing the camera to rotate and tilt freely in three-dimensional space, and even make subtle offset adjustments, thereby greatly broadening the shooting field of view and improving the flexibility and accuracy of video measurement. However, this technological breakthrough is also accompanied by cost considerations: each independent rotation in each dimension requires a dedicated motor as a power source, and the increase in the number of motors will undoubtedly increase the overall manufacturing cost. Therefore, while pursuing high flexibility, how to effectively control costs has become a problem that needs to be solved for this type of three-dimensional control camera device.
