Method and device for robot processing target positioning based on 3D scanning

Abstract

The invention discloses a robot processing object positioning method and device based on three dimensional scanning; the method comprises the following steps: using a three dimensional scanner to carry out 3D scanning for a to-be-processed part so as to obtain a point cloud model of the to-be-processed part, matching and comparing the obtained point cloud model with a standard point cloud model, thus obtaining a difference model corresponding to the to-be-processed part; carrying out gridding treatment and converting the difference model into a sparse point cloud model; setting the position of the difference value exceeding a preset threshold on the model as a polished object item needing surface polishing treatment, thus satisfying processing precision, greatly reducing computational complexity, accelerating the processing speed, reducing a computing time, satisfying real time processing requirements, reducing hardware and software performance requirements, saving cost, reducing developing difficulties, and complying with the high speed large scale production mode requirements.

Description

technical field [0001] The invention relates to the field of robot vision processing, in particular to a method and device for locating a robot processing target based on three-dimensional scanning. Background technique [0002] With the development of the manufacturing industry, surface treatment such as grinding and polishing has become a key process, and its processing quality often determines the grade of the product. Especially with the advancement of processing technology, the surface of the parts to be processed is becoming more and more complex, and the requirements for processing precision are getting higher and higher. Therefore, the confirmation and positioning of the defects on the surface of the parts is a must in the surface treatment process. indispensable process. However, the existing methods mainly rely on manual discrimination, which has a large workload and high work intensity, and it is easy to produce waste products due to missed and wrong judgments, a...
