Line laser contour measurement method, device and equipment

The embodiment of the invention provides a line laser contour measurement method, device and equipment, and relates to the technical field of laser measurement, and the method comprises the steps: controlling a drive motor to drive a line laser contour sensor to swing in a direction perpendicular to a reference plane where a measured object is located; in the swinging process of the line laser contour sensor, the line laser contour sensor is controlled to emit line laser, image data are collected in real time, and a swinging angle corresponding to the line laser contour sensor is recorded when the image data are collected each time; and performing data processing based on the acquired image data and the corresponding swing angles to obtain contour information of the to-be-measured object. According to the method provided by the invention, the contour information of the to-be-measured object can be obtained without external movement such as a conveyor belt or a sliding rail, and the dependence on an external m
