AI Technical Summary

Technical Problem

Existing three-dimensional measurement systems face challenges in accurately measuring the shape of objects when the distance between the sensor and the object is not within the appropriate range, especially when multiple objects overlap, leading to measurement errors.

Method used

A three-dimensional measurement system that utilizes a robot to adjust the position and posture of a three-dimensional sensor to maintain a predetermined reference distance from the measurement object, incorporating a control device to calculate deviations and correct the sensor's posture for accurate measurement.

Benefits of technology

Enables accurate measurement of the three-dimensional shape of objects regardless of their position, ensuring reliable detection and retrieval of workpieces.

Abstract

[Problem] To provide a three-dimensional measurement system that can accurately measure the three-dimensional shape of a measurement object without being affected by the position of the object being measured. [Solution] The first-state three-dimensional measurement system 1 disclosed herein includes: a three-dimensional measurement unit 32, which uses a three-dimensional sensor 20 that measures the distance to the measurement object to measure the position and shape of the measurement object; a robot 10, which moves the three-dimensional sensor 20 or the measurement object; a distance measurement unit 33, which measures the distance between the three-dimensional sensor 20 and the measurement object; and a measurement posture setting unit 34, which sets a measurement posture of the robot 10 such that the distance between the three-dimensional sensor 20 and the measurement object is a predetermined reference distance based on the distance measured by the distance measurement unit 33.
