Abstract

The invention discloses a visual robot data acquisition and processing system, including an image acquisition module, an image segmentation module, a camera calibration module, and a target identification module communicating with a visual system module. A plurality of segmented regions have similarity, and segmentation and combination of the regions are realized through the target identificationmodule, to complete target identification. In the process, an evaluation function is needed to be set, to distinguish true and false targets. The visual robot data acquisition and processing system can perform full-frame identification processing on each acquired frame image. The system just needs to search and perform identification processing on targets in a local region of a frame of an image,and the method is target tracking. Target tracking can greatly reduce data size processed by the system, and easily satisfies real-time requirement of the system, and some time is saved to perform other processing.

Description

technical field [0001] The invention relates to a visual robot data acquisition and processing system, which belongs to the technical field of visual robots. Background technique [0002] With the rapid development of computer vision and computer hardware technology, combining visual information with robot control to form a visual servo system, so that the robot has the ability to intelligently interact with the external environment, is a major direction of robot development today; robot visual servo system By detecting the target object in the image, visual information can be obtained to control the movement of the robot; the position-based visual servo method first estimates the relative position of the target object in the Cartesian coordinate space relative to the camera according to the model of the robot, the accessible workspace and the target object. position; in computer image processing, visual tracking based on the analysis and understanding of dynamic images has ...
