Study on the Theory of Welding Seam Detecting Sensor Based on Structure Light
The influence of arc noise to laser strip image is studied comprehensively, and the arc noise model is established. Originating from the principles of projective and perspective transformation, the models of coordinate transformation between workpiece and camera with arbitrary angle of laser light and camera are presented. Both of the models are very useful to the design of structure light sensor. The sensor designed based on the theory above is used in automatic welding.
