Title:
THREE-DIMENSIONAL MEASUREMENT DEVICE, THREE-DIMENSIONAL MEASUREMENT DEVICE, MOVING ROBOT, WHEELBARROW-TYPE MOVING DEVICE, AND THREE-DIMENSIONAL MEASUREMENT PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2020/121406
Kind Code:
A1
Abstract:
The purpose is to provide a three-dimensional measurement device and a three-dimensional measurement processing method capable of acquiring a three-dimensional map while suppressing memory consumption. A three-dimensional measurement device comprises: a three-dimensional image acquisition unit 10 that acquires a three-dimensional image including three-dimensional point group data that is a set of data about three-dimensional points, the three-dimensional point being a three-dimensional image of a target to be measured and being points on the surface of an object in a three-dimensional space; a three-dimensional map generation unit 20 that combines three-dimensional images to generate a three-dimensional map in which a three-dimensional shape of the target to be measured is represented by combined three-dimensional point group data; a polygon extraction unit 30 that extracts a polygon from three-dimensional point group data constituting the three-dimensional map or three-dimensional point group data that is included in the three-dimensional image and is used to generate the three-dimensional map; a map evaluation unit 60 that evaluates the quality of the three-dimensional map on the basis of the polygon, and a measurement plan generation unit 70 that generates, on the basis of an evaluation result of quality of the three-dimensional map, a measurement plan including information indicating a target region to be measured or a measurement position for which a three-dimensional image is to be acquired.
