technical field

The utility model belongs to the technical field of tunnel detection, in particular to a camera fixing device for tunnel image collection.

Background technique

A camera, referred to as a camera, is a device that uses the principle of optical imaging to form an image and uses a film to record the image. Many devices capable of recording images have the characteristics of a camera. Medical imaging equipment, astronomical observation equipment, etc. A camera is an optical device used for photography. After the light reflected by the subject is focused by the camera lens and the shutter that controls the exposure, the subject forms a latent image on the photosensitive material in the dark box, and is processed to form a permanent image. This technology is called photography. In the process of tunnel construction, operation and maintenance, functions such as modeling and disease identification and detection can be realized by taking pictures of the outline of the tunnel and combining image recognition and processing technologies. Therefore, it is necessary to install multiple acquisition cameras in the tunnel to monitor information is collected, but it also creates a lot of problems.
