Automatic positioning method and system for underground coal mine drilling machine holder based on radar technology

The invention relates to the technical field of clamp holder positioning, in particular to an automatic positioning method and system for an underground coal mine drilling machine clamp holder based on the radar technology. When the underground coal mine drilling machine clamp holder is automatically positioned, obtained laser point cloud data is cut in a similarity comparison mode; according to the method, only the laser point cloud data containing the information of the holder is reserved, and then the holder is automatically positioned according to the laser point cloud data only containing the information of the holder, so that excessive errors are prevented from participating in positioning calculation, and the positioning accuracy is improved. 本发明涉及夹持器定位技术领域，尤其涉及基于雷达技术的井下煤矿钻机夹持器自动定位方法及系统，本发明在对井下煤矿钻机夹持器自动定位时，通过相似度比较的方式对获取的激光点云数据进行裁减，仅仅保留包含夹持器信息的激光点云数据，然后根据仅包含夹持器信息的激光点云数据对夹持器自动定位，这样避免了过多的误差参与定位计算，提高了定位的准确度。
