To solve the problem of workpiece target accurate positioning in industrial environment, we proposed a method that used object's surface point cloud which created by stereo matching of binocular vision. Firstly, found out the ROI(Region Of Interest) of the stereo matching point cloud by template matching, and used an algorithm of noise reduction to gain a clean ROI point cloud. And then, extracted...
Non-uniform illumination makes it's difficult to detect and extract the target. To locate multiple target under complicate illumination, an improved vision system was designed in this paper. After analyzed kinds of image-binaryzation strategy, we choose the adaptive threshold binarization as the image binarization strategy. Through image processing, morphological processing, adaptive threshold binarization...
Litchi fruit mechanized flexible picking could effectively solve the issue of the labor shortage at harvest time, and achieve high efficiency of harvesting fruit without injury, which have an important prospects of development and application. This paper designed a PP-RRR manipulator with S-joints DOF. By applying CAD graphic method, analyzed the structure size of manipulator in the height of 1-3...
The intelligent role in virtual environment can be located when using vision to get the target image, but there is a source separation problem in case of unknown complex natural signals. In order to resolve the source separation problem, this paper proposed the target three-dimensional modeling based on the visual image processing of virtual robot; applied the method based on the nonlinear Principle...
