Abstract

A video-assisted laser displacement detection device belongs to the technical field of bridge deflection detection. The device includes a mobile bracket, a laser, a backplane, a backplane bracket, a camera, and a camera connecting rod. The backplane is marked with a horizontal and vertical coordinate scale. The laser is fixed on the mobile bracket, the backplane is fixed on the backplane bracket, and the camera is fixed on the camera. Above the connecting rod, the camera connecting rod is fixed above the back plate. When in use, the mobile bracket is fixed on the target object, moves with the target object, adjusts the angle of the backplane so that the laser emitted by the laser is perpendicular to the backplane, and automatically captures the displacement of the laser point through the camera to determine the displacement process of the target object. The device determines the displacement process of the target object by means of laser positioning and the camera captures the displacement of the laser positioning point, which can more intuitively determine the moving process of the target object and improve the detection accuracy.
