POINT CLOUD DATA DISPLAY SYSTEM

A point cloud data acquisition system that provides a technology to enable checking of a point cloud data acquisition status on a map in real time at a survey site, includes a target unit including a reflection target, a scanner device configured to perform a distance measurement by transmitting distance measuring light and receiving reflected distance measuring light reflected by a measuring object, scan a measurement range with the distance measuring light, and detect an angle of the distance measuring light to acquire point cloud data of the measurement range, a surveying device configured to measure a distance and an angle to the reflection target and calculate measured coordinates and a direction angle of the scanner device based on distance and angle measurement data of the reflection target, and a display device configured to display data output from the scanner device and the surveying device, wherein the scanner device outputs point cloud data to the display device in association with an observation point each time of acquisition of the point cloud data, the surveying device outputs coordinates and a direction angle of the scanner device at the observation point to the display device in association with the observation point, and the display device converts point cloud data into data in a map coordinate system when all of point cloud data and coordinates and a direction angle of the scanner device are obtained with respect to the observation point, and displays the converted data on a display unit in association with a map.
