摘要
将激光摄像技术运用到地铁设备限界检测,对相邻摄像机不重合、不完整的检测轮廓进行融合拼接。根据分析所得到标定精度较差摄像机与相邻摄像机视觉重合远处出现检测轮廓数据出现不重合、完整的原因,采用迭代最近点(ICP)算法并结合杭州地铁二号线地铁设备限界的检测轮廓数据,对所检测设备限界不完整的轮廓进行融合拼接。研究结果表明:基于激光摄像技术检测技术能够更加快速、高效的实现设备限界的非接触式检测;采用ICP算法实现精度较差摄像机与相邻摄像机视觉重合远处设备限界检测轮廓的融合拼接,可以使设备限界检测更加完整、可靠,对保障地铁的安全运行具有现实意义。
Metro Equipment Gauge Detection based on Laser video camera technique was used in this paper,and achieved no overlap and incomplete equipment gauge contour data fusion and splicing. According to the analyzed reason of distance overlap visual of bad calibration accuracy video camera and adjacent video camera detecting contour data appear no overlap and incomplete. Combining with equipment gauge contour data of Hangzhou Metro Line 2,and using ICP algorithm to achieve equipment gauge contour data fusion and splicing. The results show that laser video camera technique can achieve faster and more efficient non- contact equipment gauge detection. ICP algorithm complete image fusion and splicing of distance overlap visual of bad calibration accuracy video camera and adjacent video camera detecting contour data can make the detection of equipment gauge more complete and reliable. The conclusions have practical significance for the safe operation of the metro security.
