Research of Performance Testing Method of Section Monitoring System for Roadheader

Abstract

The paper presented a performance testing method of section monitoring system according to general working principle of section monitoring system. The method measures spatial position of feature point on cutting header by setting references of roadheader and roadway, and projected spatial track of a series feature points obtained on the plane where section outline was defined according to the references of roadheader and roadway when cutting header completes section scanning under guiding to section monitoring system, so as to form a real section outline. Finally, the method compared the real section outline with the defined one according to indexes of angle error, position error and shape error to complete performance evaluation of section monitoring system. The experimental result showed that the method is effective and accurate.
