Problems solved by technology

However, the light intensity output by the fill light is fixed, that is, the fill light intensity is the same no matter in a brighter or darker environment, which will lead to poor brightness and contrast of the image, which cannot reach the user's expectations. Expected effect, seriously affecting the quality of captured images

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...
