COMPUTING DEVICE, COMPUTING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/062781
Kind Code:
A1
Abstract:
[Problem] To enable acquisition of three-dimensional information obtained from a viewpoint on a construction machine. [Solution] This computing device: receives measurement data measured by tracking the position of a reflection prism 102 on a construction machine 100 equipped with a laser scanner 101 and the reflection prism 102 using a total station 200 of which the position and the attitude in a specific coordinate system are known; acquires a laser scan point cloud obtained by the laser scanner 101; transforms the coordinates of the laser scan point cloud to those in the specific coordinate system on the basis of the measurement data and the attitude of the laser scanner 200; detects a change on the time axis in point cloud data obtained through the coordinate transformation; and identifies the contents of the work being performed by the construction machine on the basis of the change on the time axis in the point cloud data.
