Problems solved by technology

[0003] Most of the existing robot control is to fix the assembly point and the position of the robot, so as to measure and formulate the positional relationship in advance to achieve accurate in-position movement. However, once the workpiece to be assembled deviates, it needs to be readjusted, wasting a lot of time

Abstract

The invention discloses a workpiece three-dimensional positioning system and method based on point cloud data. The data of the depth camera is converted into the position information of the assembly point through the visual analysis mechanism, so as to obtain the real-time accurate position relationship, regardless of whether the workpiece to be assembled changes its position or not. , can provide accurate position information for subsequent robot actions, and realize fast and accurate assembly actions.

Description

technical field [0001] The invention relates to the technical field of assembly robot control, in particular to a three-dimensional workpiece positioning system and method based on point cloud data. Background technique [0002] For the consideration of fully automatic assembly, whether the control of the robot in the assembly process is accurate or not directly affects the assembly result. The assembly and the workpiece to be assembled are set as a set, and the two must be completely fitted before the assembly is complete, such as the common hole shaft assembly. , the hole is the workpiece to be assembled, and the shaft is the assembly. To fully insert the shaft into the hole requires accurate positioning of the center of the hole, and at the same time accurately controls the manipulator to move the shaft to the center of the hole to complete the assembly. [0003] Most of the existing robot control is to fix the assembly point and the position of the robot, so as to measur...
