Abstract:

Through the study of laser ranging sensor and machine vision using laser ranging sensor, vision sensor, based on a combination of methods, this paper proposes a different in structured light and binocular size measurement of more simple and effective new method and new technology. Firstly, the optimal filtering method is selected by comparing the gray histogram, then the edge detection is performed by the laser ranging sensor and the monocular vision sensor. The laser ranging sensor realizes the fast ranging and positioning of the sampled targets, and calculates the relative position between the sampling manipulator and the target vehicle. The vision sensor can accurately identify the size and location of the car, which provides the basis for the automatic sampling of coal sampling manipulator. Detection goal is pull coal freight train, for the coal sampling industry to bring more simple, effective and accurate target location identification system and methods.
