Abstract

The invention provides a light supplementing device for a tunnel detection image capture device. The light supplementing device for the tunnel detection image capture device comprises a plurality of light supplementing units; a plurality of the light supplementing units are uniformly distributed on a support, and the support is parallel to a tunnel section; a light source set and an image capturedevice are mounted on the support; each light supplementing unit comprises the light source set and the image capture device, and the light source set is arranged on the lateral surface of the image capture device; the light source set is provided with a lamp shade; and the light supplementing units are distributed on the support in 1 / 4 of an arc. The illumination light supplementing device for the tunnel detection image capture device can effectively solve the problems of illumination and over-exposure while capturing images in tunnel environments at present.

Description

technical field [0001] The invention relates to the technical field of tunnel detection, in particular to an illumination supplementary light device used for a tunnel detection image capture device. Background technique [0002] In recent years, with the rapid development of urban construction and the continuous expansion of urban scale, urban subway traffic has developed rapidly with its unique advantages. Metro tunnels have extremely high requirements for operational safety. During the operation, management and maintenance of subway tunnels, regular Detection and timely detection and treatment of tunnel structural defects such as cracks, water leakage, etc. At present, the structural detection of subway tunnels mainly relies on manual detection methods. Manual detection is slow, inefficient, and increasingly unsuitable for modern subway tunnels. The detection window time is short Therefore, the research on the rapid and automatic detection technology of subway tunnel struc...
