Technical Field

[0001] The utility model belongs to the technical field of photography, and in particular relates to a camera device applied to three-dimensional geological modeling of tunnels. Background Art

[0002] A camera usually consists of two parts: a body and a lens. The development of existing cameras tends to make the lens and the body more integrated, reduce the size of the camera, make the camera lighter and easier to carry. However, the field of view of camera lenses on the market is limited to the front of the camera lens, and it is impossible to directly achieve fast and effective integrated shooting of the annular surface. It is necessary to constantly adjust the shooting angle of the camera lens, which is often time-consuming and inconvenient to operate. In the engineering field, it is often time-consuming and laborious to collect photo information of tunnel geological morphology using existing cameras. There is a lack of a fast and effective means of shooting the annular surface of the tunnel. The electronic informationization of tunnel geological conditions has always been a time-consuming technical problem in the field of engineering survey. Utility Model Content
