Abstract

The invention discloses a laser scanning measurement device for acquiring spatial distribution of target objects. The device comprises a laser rangefinder module, a global positioning module, an attitude measurement module and a data processing module, wherein the laser rangefinder module is used for conducting laser scanning on the target objects to determine the relative positions of multiple scanning points on the target objects, the global positioning module and the attitude measurement module are used for obtaining the position and attitude of the scanning measurement device in the geodetic coordinate system, and the data processing module is used for obtaining the positions of the scanning points in the geodetic coordinate system, namely the spatial distribution condition of the target objects, through coordinate transformation. The invention further provides a laser scanning measurement method for acquiring spatial distribution of the target objects. The scanning measurement process is fast and efficient. The device and method are suitable for scanning measurement of target objects in any shapes.

Description

technical field [0001] The invention relates to the technical field of surveying and mapping, in particular to a laser scanning measurement device and method for acquiring the spatial distribution of objects. Background technique [0002] The 3D laser scanner uses the laser ranging device to record the 3D coordinates, reflectivity, texture and other information of a large number of dense points on the surface of the measured object, and quickly reconstructs the 3D model of the measured object and its lines, surfaces, volumes, etc. kinds of map data. Since the 3D laser scanning system can intensively acquire a large number of data points of the target object, compared with the traditional surveying and mapping technology, the 3D laser scanning technology has its breakthrough. [0003] According to a large number of research and analysis, it is found that although the 3D laser scanning technology can quickly draw the 3D point cloud map of the target object, there are still di...
