Abstract

The invention discloses a large-size workpiece movement measurement robot system and method. The system and method are based on a target tracking system, and depends on a mobile device, and a visual measurement system and a three-dimensional target which are carried by a robot, and a global control means is created, thereby enabling the target tracking system, the visual measurement system and thethree-dimensional target to be combined, removing the tedious step of pasting a target in a conventional visual measurement system, avoiding an error caused by the target matching and the impact on ameasurement error from the robot, and achieving the automation of high-precision measurement. The coordinate system of the target tracking system is the world coordinate system, and the point cloud data measured by the visual measurement system is unified in the world coordinate system. The calibration precision plays a key role in a final measurement result. Before measurement, the motion planning of the large-size workpiece movement measurement system and the calibration of a measurement system need to be completed, so as to achieve the automatic measurement of the large-size workpiece movement measurement robot system.

Description

technical field [0001] The invention belongs to the technical field of measurement, and in particular relates to a mobile measuring robot system and method for large-scale workpieces. Background technique [0002] In recent decades, long-distance, high-precision and large-scale coordinate measurement systems have been widely demanded in industrial fields such as aerospace, automobile and shipbuilding, hydroelectric power, steel, and transportation. With the development of large-scale equipment manufacturing industry, users' requirements for product quality control are also constantly improving, and industrial product design and manufacturing technology are constantly innovating. Due to the integrated characteristics of measurement functions, the traditional large-scale measurement system has been unable to meet the growing requirements of large-scale spatial coordinate measurement on industrial sites. Contents of the invention [0003] In view of this, the present inventi...
