Abstract

The invention discloses a visual positioning method, which is executed in computing equipment and comprises the following steps of: acquiring a welding seam image on the surface of a workpiece; determining welding seam feature points and image coordinates thereof on the welding seam image based on the welding seam extraction template; and determining world coordinates of the weld joint feature points based on the image coordinates, wherein the workpiece is welded based on the world coordinates of the weld joint feature points. The invention also discloses a visual positioning system, a visual positioning method executed in the system and computing equipment. According to the visual positioning method, accurate positioning of the fillet weld coordinates can be achieved, so that the efficiency of weld extraction and weld positioning is improved.

Description

technical field [0001] The invention relates to the technical field of intelligent welding, in particular to a visual positioning method, system and computing equipment. Background technique [0002] At present, most of the workpiece welding is through manual welding. Manual welding not only has low efficiency and limited production capacity, but also has uneven welding quality and unsightly finished products. Therefore, in the fields of ships, aerospace, construction machinery and rail transit, the use of welding robots to realize intelligent welding is of great significance for improving welding quality and welding efficiency. [0003] When using a welding robot for intelligent welding, the core issue is how to efficiently and accurately locate the coordinates of the weld. Traditionally, the robot teaching method is used for welding seam positioning. In this method, the robot can only weld according to the preset trajectory. Therefore, when the workpiece size and positio...
