Research on vehicle 3D data measurement method based on line laser scanning

The three-dimensional reconstruction of vehicle surface point cloud can provide effective reference data for robot path planning of vehicle surface spraying. A three-dimensional data measurement method of vehicle surface based on line laser sensor is proposed in this paper. This paper collects the point cloud information of vehicle surface by line laser sensor, extracts the effective three-dimensional information of vehicle surface. and takes the regular block and vehicle model as the experimental object, use the measurement system with the sensor clamped by the manipulator to measure the three-dimensional data, compare the point cloud data accuracy under different measurement depth and scanning speed, and reconstruct the vehicle model. The research shows that this method is feasible.
