Bridge structure dynamic displacement monitoring and sensing system based on laser scanning

A bridge structure dynamic displacement monitoring and sensing system based on laser scanning comprises a laser emission source, a laser receiving and imaging device, a signal processing control device, a fixed base and a to-be-measured structure, the laser emission source is installed on the fixed base, the fixed base and the to-be-measured structure are arranged oppositely, and the laser receiving and imaging device is installed on the fixed base. The laser receiving imaging device is installed on the to-be-detected structure and used for detecting the dynamic displacement of the to-be-detected structure, and the laser emission source and the laser receiving imaging device are connected with the signal processing control device and transmit a detected dynamic displacement signal of the to-be-detected structure to the control module. And after receiving the signal, the control module processes the signal and displays the dynamic displacement of the to-be-tested structure. According tothe utility model, only
