The invention discloses an interactive automatic welding method based on three-dimensional vision. The interactive automatic welding method comprises the following steps that an interactive automatic welding system based on the three-dimensional vision is built; a three-dimensional model of a to-be-welded workpiece is obtained; a workpiece coordinate system and a robot coordinate system are aligned by using three-dimensional vision; to-be-welded features are selected in an interactive interface, and a welding track is generated; and welding is performed using a robot. According to the interactive automatic welding method, three-dimensional vision is combined with an interaction system, and the online programming or on-site teaching process is changed into an automatic welding system based on image interaction. Compared with traditional online programming and field teaching schemes, the automation degree is higher, labor is saved, and efficiency is improved; meanwhile, the programming skill requirement on front-line operators is also effectively reduced; and in addition, remote control can be achieved through the method, or one worker can control multiple devices, and unmanned flexible welding can be achieved.
Description
Technical field: [0001] The invention relates to an interactive automatic welding system and method based on three-dimensional vision, which mainly uses a three-dimensional digital model combined with robot technology to complete the setting of welding tasks in an interactive manner, and then guides the robot to complete the automatic welding tasks. The invention belongs to the fields of industrial automation and machine vision. Background technique: [0002] In the field of robot automation welding, widely used methods include on-site teaching programming and off-line programming. On-site teaching programming, through manual coordinate alignment, find the starting point or trajectory of welding, input it to the robot system, and then use the robot to perform automated welding. This method is suitable for small batches of flexible welding scenarios, but its use is very limited due to the high requirements for on-site workers; in addition, because the teaching process is ver...
