使用红外热像仪探测自燃煤矸石山表面温度时，获取的热红外影像缺乏与之对应的空间信息，难以进一步分析其温度场信息，精确探测着火点，为解决该问题，利用近景摄影测量的方式获得煤矸石山表面的空间信息，将其与煤矸石山表面温度融合得到自燃煤矸石山的温度场信息，并利用 ArcGis 软件构建其红外三维模型。通过实验验证了该方法具有可行性，并进行了误差分析。研究结果表明，该方法得到的三维模型点位误差在0??07 m 范围内，可以满足实际煤矸石山表面着火点探测的需求。

When using thermal infrared imagers to detect surface temperature of spontaneous coal gangue piles,the infrared images lack corresponding spatial information,it is difficult to anG alyze information of temperature filed and precisely plumb the kindling point?? In order to solve the problem,the authors used close range photogrammetry method to get surface special inforG mation of coal gangue pile,and ArcGis software to construct infrared 3D model which were feasiG ble in the experiment?? The analysis results of errors showed :position errors of the 3D model were less 0??07 m,and it could meet the actual requirement of plumb the kindling pointin coal gangue piles.
