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...
Robots and automation technology has been increasingly used in the production of leather shoes. How to get the work trajectory is one of the key problems. Methods that can generate robot spraying trajectory by extracting shoe sole information were presented. The information including shoe sole surface and contour line could be obtained by off-line program with CAD technology and on-line program with...
This paper presents the mobility analysis of two parallel mechanisms, 4-RPRPR and 4-RRRRR, by screw theory. It is shown that the two parallel mechanism have the bifurcation of Schoenflies motion. In the singular configuration with the moving platform being parallel to the base, the moving platform has three finite translational degrees of freedom (DOFs) and two instantaneous rotational DOFs. The rotation...
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...
In shoe manufacturing, in order to attach the upper with the corresponding sole, it is necessary to ‘scrape’ certain material off the upper surface so that the glue can penetrate the leather and adhere; an operation called ‘roughing’. This paper presents the implementation of an innovative apparatus for roughing and adhesive spray of a shoe upper. The accuracy needed to follow the complex 3D (3 dimensional)...
The key problem in automatic shoe upper spraying system is how to get a reliable trajectory for spraying. To extract information of shoe upper and generate the trajectory for shoe upper spraying quickly, a method based on computer vision with structured light is described. After scanning a shoe lasted upper with the sensor of structured light and CCD camera, basic information of shoe upper rendered...
Modern logistic automation systems need the ability to cooperatively execute some complicated tasks in an efficient way. In order to meet this requirement, a kind of cooperative multi-robot logistic system based on agent is proposed, and the distributed multi-agent architecture for such intelligent production system is designed. The architecture consists of information agent, object agent, decision-making...
