The invention discloses a centrosymmetric workpiece automatic welding device and method based on visual measurement. An industrial robot, a welding gun, a 2D camera, a 3D camera, a controller and an industrial personal computer are electrically connected to a switch, and the switch is used for achieving communication between connecting devices; the controller is electrically connected to the linear module, and the industrial personal computer is electrically connected to the display screen; intelligent welding general control software is installed in the industrial personal computer. Communication connection and data interaction between the 2D/3D vision sensor and the welding robot can be established, and vision-driven robot intelligent welding is accurately achieved; the automatic welding device has a larger working space, so that the welding accessibility is improved, and the effective welding area of the robot is expanded; according to the automatic welding system, the centrosymmetric toggle plate type wor
