Blasting Hole Recognition and Location Based on Machine Vision

Abstract

In order to guide the manipulator putting explosive into the blasting hole automatically, a hole recognition and location method based on machine vision is presented. First, capture the target blasting hole pictures from two different directions by a camera mounted on the manipulator. Then, use binocular calibration method to get the hole position based on the camera coordinate. Finally, transform the camera coordinate system to the manipulator coordinate system, and then the target hole position is obtained. The experimental results show that this method has high detection accuracy and achieves a better blasting hole location.
