Abstract
A measurement system and associated techniques can reduce the time for obtaining 3D data about a target object by measurement. The measurement system includes a 3D sensor installable on a robot to obtain, by measurement, 3D data indicating 3D coordinates of surface points on a surface of a target object, a displacement detector that detects a displacement of a joint of the robot, a drive that drives the joint of the robot, a sensor controller that controls the 3D sensor to obtain 3D data about the target object by measurement at one or more measurement points, an integrator that performs 3D integration of 3D data about the target object obtained by measurement before a first operation performed by the robot on the target object and 3D data about the target object obtained by measurement at the one or more measurement points after the first operation performed by the robot on the target object, and a robot controller that outputs, to the drive, a drive command for controlling a second operation performed by the robot based on 3D coordinates of the surface points on the surface of the target object indicated by 3D data obtained through the 3D integration.
