Laser radar data acquisition system and data processing method

The invention relates to the technical field of data acquisition and modeling, particularly to a laser radar data acquisition system and data processing method. The laser radar data acquisition systemcomprises a data acquisition device and a data processing device. The data acquisition device is at least used for acquiring laser point cloud data of an area to be monitored and coordinate information corresponding to the point cloud data; the data processing device at least comprises a noisy point filtering unit and a curved surface generating unit. The noisy point filtering unit is used for filtering the laser point cloud data and removing noise points in the laser point cloud data, the curved surface generating unit is used for generating a triangular curved surface according to the laserpoint cloud data subjected to noise removal and corresponding coordinate information, and the triangular curved surface is used for calculating geographical space information of the area to be monitored.
