Other AbstractThe invention discloses a visual welding seam surface quality real-time on-line detection sensor based on line structure light, comprising sensing units and an image processing unit, wherein two sensing units are respectively vertically installed at two sides of the upper and lower surfaces of the welding seam and connected with the image processing unit the sensing units comprise a video camera for receiving the welding seam surface gray scale image including laser stripe formed on the welding work piece a straight linear laser for generating laser structure light stripe on the welding work piece an optical filter in front of the video camera lens and an LED annular light source coaxially provided with the video camera and positioned in front of the optical filter. The invention uses the straight linear laser to project onto the upper and lower surfaces of the welding seam to generate the laser stripes the camera collects the welding seam surface gray scale image including laser stripes to finally realize automatic quality detection of the upper and lower surfaces of the welding seam and the precision of surface quality detection of the welding seam is improved. The sensor can be widely applied to the fields such as robot automatic welding.
