A Visual Computing Method for Coal Mine Roadway Deformation

Abstract:

In order to make more precise monitoring and automation of roadway, the paper presents a method based on computer vision. The first step is to get the edge information of marked points though image preprocessing, then calculate the planar coordinates of marked points and decode. The next is to set up the camera model to solve all the initial parameter and distortion coefficient of camera and initial marked points. Finally, the bundle-adjustment can refine all the camera parameter and the three-dimensional of marked points. Experience shows the method can achieve accurate three-dimensional information and make efficient adjustment about roadway deformation.
