Encoder-decoder small bridge bottom crack detection system and method based on reverse residual bottleneck

The invention aims to provide an encoder-decoder small bridge bottom crack detection system based on a reverse residual bottleneck. The encoder-decoder small bridge bottom crack detection system based on a reverse residual bottleneck comprises an industrial camera set arranged at the bottom of a bridge and used for shooting a video of a bridge bottom crack in a translation mode, the camera set is connected with a remote WiFi transmission module, the WiFi transmission module is arranged in a camera, and data can be transmitted only when the computer and the camera are in the same frequency band; power supply equipment of the industrial camera is powered by solar energy, and a solar panel and small voltage conversion equipment are tightly attached to the side wall of the bridge. After the computer obtains a video, video frames are dynamically extracted as images, an encoder-decoder model of a reverse residual bottleneck is built in the computer, the computer is used for detecting whether cracks exist in the ima
