The present invention relates to the technical field of automatic spraying, in particular to an automatic spraying method and system based on machine vision, the system comprising: a PLC, a frequency converter connected to the PLC, a first infrared sensor, a second infrared sensor and a switch; The frequency converter is also connected to a motor, the switch is also connected to an industrial camera and an industrial computer, and the industrial computer is also connected to a spraying robot; the infrared signal is sensed by the first infrared sensor, thereby controlling the motor to start and run, And carry out image shooting, when the second infrared sensor senses the infrared signal, the frequency converter controls the motor to stop running, and the industrial camera stops image shooting; when the industrial computer matches the local image corresponding to the image, obtain the corresponding local image spraying program, and control the spraying robot to carry out the spraying operation according to the spraying program, and the present invention can automatically adjust the spraying process according to the texture of the workpiece.
Description
technical field [0001] The invention relates to the technical field of automatic spraying, in particular to an automatic spraying method and system based on machine vision. Background technique [0002] With the vigorous development of science and technology in our country, the application of machine vision and industrial robots will become more and more extensive. The combination of industrial robots and machine vision can make spraying more intelligent. In addition to being used for image recognition in the field of industrial control, industrial cameras can also extract the texture and contour of the workpiece, thus providing a basis for automatic spraying and spraying path planning. [0003] Existing spraying equipment can only carry out the same spraying process on the workpiece, and because the texture of the workpiece is different, different patterns need to be sprayed, and the spraying process often needs to be changed, and the spraying operation is very troublesome....
