Space positioning system for intelligent assembly and space positioning method for intelligent assembly

Abstract

The invention discloses a space positioning system for intelligent assembly. The space positioning system for intelligent assembly can carry out space positioning on target objects which are complex in shape. The space positioning system for intelligent assembly comprises a robot control cabinet, a robot module, a 3DL camera, an image processing module, an algorithm calculating module and a positioned target object. The invention further discloses a space positioning method for intelligent assembly. The space positioning method for intelligent assembly comprises the steps of (1) building a user coordinate system and a tool coordinate system of the 3DL camera, (2) calibrating the 3DL camera in the user coordinate system, (3) taking eight photograph points in the edge of the target object to photograph, (4) carrying out binarization processing on photographed images of each point, and obtaining feature points of each photograph point, (5) extracting space position information of each feature point in the user coordinate system, (6) transmitting the space position information of each feature point in the user coordinate system to the robot control cabinet, and (7) calculating a space position coordinate system of the target object according to the space position information of the eight feature points on the target object.

Description

technical field [0001] The invention relates to a space positioning system and a positioning method for intelligent assembly. Background technique [0002] Assembling is the follow-up process of product production and plays an important role in the manufacturing industry. At the same time, assembly accuracy plays a key role in the overall quality of the product. In order to improve production efficiency and assembly automation level, ensure product quality, and reduce costs, intelligent assembly systems based on robotics and vision technology are being vigorously promoted. The basic principle of this intelligent assembly method is: the robot obtains the spatial position information of the fixed target object through the vision system, and uses this spatial information to carry out automatic assembly with another target object held by the robot. In this intelligent assembly process, the most critical link is the acquisition of spatial position information of fixed objects. ...

Problems solved by technology

The Chinese patent "Simple and Flexible Positioning Method for Continuous Surface of Target" (Patent No.: CN101745824A) discloses a method of using laser tracker for target positioning, but this method requires the target ball to be in contact with the target, and the measurement efficiency Low

Since the installation accuracy of this installation method is guaranteed by the labor quality of the workers, the installation accuracy and consistency are poor, and the labor intensity of the workers is high.
