Mechanical arm optical guidance system for automatically shielding external light source interference

Abstract

The invention provides a mechanical arm optical guidance system for automatically shielding external light source interference, and relates to the technical field of industrial mechanical optics, in particular to improvement of a guiding system of an industrial robot arm. The optical guidance learning system comprises optical recognition mechanisms, wherein the plurality of the optical recognitionmechanisms are arranged, and the optical recognition mechanisms are arranged at different positions of a mechanical arm; the optical guidance learning system acquires an image of an operated materialthrough a plurality of optical recognition mechanisms, and performs image rendering on the operated material, and image rendering comprises edge stroking and point setting processing on an outer edgeof the operated material, calculating and point setting processing on edges of all ends of the operated material, brightness registration processing on the operated material, color registration processing on the operated material, workbench top registration processing on the operated material, background natural light brightness registration processing on an operation scene of the mechanical arm,and background lamp light brightness registration processing on the operation scene of the mechanical arm. The system can identify the material being operated, grabbed and processed, and shield the external light source interference, thereby guaranteeing accuracy of the mechanical arm under optical guidance, preventing misoperation, and further improving the accuracy and stability of guidance.

Description

technical field [0001] The invention relates to the technical field of industrial mechanical optics, in particular to the improvement of a guiding system of an industrial mechanical arm. Background technique [0002] Industrial robotic arms are mechatronic devices that simulate the functions of human arms, wrists, and hands. It can move any object or tool according to the time-varying requirements of space posture (position and attitude), so as to complete the operation requirements of an industrial production. Industrial robotic arms are mainly used in the field of automated and semi-automated production. The robotic arm can replace a lot of repetitive work of workers on the production site. [0003] In order to better operate the robotic arm, it is usually necessary to guide and position the robotic arm. At present, the common positioning is active positioning, that is, the coordinate system is established through the position of the robot arm itself. It needs to be adj...

Problems solved by technology

At present, some companies at home and abroad have developed optical vision guidance methods. The current optical guidance system technology is not mature enough, especially it is difficult to accurately identify the materials and their own positions in the scene, and it is especially easy to be interfered by external light sources, resulting in guidance. error, which eventually leads to operator error, is the biggest obstacle to current optical guidance systems
