Robotic Flexible Measuring System for 3D Topography of Large and Complex Surfaces

Abstract

The robot flexible measurement system for three-dimensional shape of large and complex surfaces belongs to the field of shape measurement technology, which solves the lack of flexibility of measuring equipment in the existing technology and cannot realize online measurement; the degree of automation is low, the accuracy of point cloud stitching is low, and the measurement efficiency is low. Technical issues to be improved; the measurement method of this measurement system includes the following steps: Step 1: Establish a complex surface measurement system model; Step 2: Plan the trajectory of the complex surface, and perform offline programming; Step 3: Measure the three-dimensional shape of the complex surface; Step 4: Process the measurement data of complex curved surfaces, and use the global point cloud splicing technology based on IGPS to complete the splicing of point cloud data; the present invention can change the robot control program at any time for different measurement products to adapt to different measurement requirements; industrial robots It can communicate with the computer in real time, which improves the automation of the system.

Description

technical field [0001] The invention belongs to the technical field of shape measurement, and in particular relates to a flexible measurement system for a three-dimensional shape robot of a large complex curved surface. Background technique [0002] In modern industrial production, especially in aerospace, automotive, weaponry, mold manufacturing and other fields, there are more and more parts with complex curved surface shapes, and the requirements for the structure and shape of parts are very high. Traditional manual offline measurement The method can no longer meet the needs of modern production for surface measurement. How to measure curved surfaces accurately, quickly and online has become one of the current research hotspots; in addition, the speed of product upgrading is accelerating. , more and more tend to develop to flexible production methods with multiple varieties and small batches. If enterprises still adopt traditional fixed detection methods, even if this met...
