Computer vision systems are playing an important role in 3D measurement for industrial applications. A method of image process and features extraction for structured light stripe image of Tailored Weld Blanks with arc and splash disturbance is proposed. Then, the target image is pre-processed using image median filtering and setting range of interest. Furthermore, several thresholds of Gray Centroid...
This paper describes the development of laser stripe sensor for automatic 3D Curve detection for Shoe Sole Spraying. It also presents the implementation of a new apparatus for adhesive spray of the shoe upper. Laser stripe sensor which is used to obtain profile of shoe sole upper plays an important part in the production of leather shoes. The sensor consists of a CCD camera and a stripe-type laser...
This paper deals with a seam tracking system of welding of tailored weld blanks based on active laser-triangulation. The system consists of DSP based vision camera and stripe-type laser diode. The total system is assembled into a compact module which can be attached ahead of welding torch and it has high dynamic performance in guiding the robot arm welder accurately over the seam. its structure, basic...
An on-line visual tracking sensor system for the automation of laser welding processes in heavy industries is presented. A method of image process and features extraction for structured light image of laser welding has been developed. In order to set the range of interest, the Radon Transform is applied to determine the x and y coordinate in image coordinate system. For image de-noising, the median...
