Title:
MOVABLE THREE-DIMENSIONAL LASER SCANNING SYSTEM AND MOVABLE THREE-DIMENSIONAL LASER SCANNING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/197617
Kind Code:
A1
Abstract:
Provided is a movable three-dimensional laser scanning system, comprising: a movable scanning device (100) and a first signal processor (200). The movable scanning device (100) comprises a three-dimensional point cloud scanning instrument (120) and a sensing component (110). The three-dimensional point cloud scanning instrument (120) is used to perform three-dimensional scanning at different scanning locations and obtain corresponding point cloud data. The sensing component (110) is used to measure various parameters required by a simultaneous positioning and mapping algorithm. The first signal processor (200) is electrically connected to the three-dimensional point cloud scanning instrument (120) and the sensing component (110) respectively. The first signal processor (200) is used to update location and status information of a scanning center of the movable scanning device (100) in real time by means of the simultaneous positioning and mapping algorithm on the basis of data collected by the sensing component (110), and is further used to register point cloud data corresponding to any scanning center to a world coordinate system on the basis of real-time location and status information of the scanning center.
