The invention discloses a train derailment safety monitoring and early warning method and device.The device comprises a fixing support, laser instruments and cameras, the fixing support is located near one side of the advancing direction of wheels, the two laser instruments are installed in the fixing support, the laser projection angles are located to the contact profiles of the wheels and a steel rail respectively, a pull rod is arranged on the lower portion of the fixing support, and the cameras are arranged on the pull rod. A camera is installed on the pull rod, the shooting angle of the camera is aligned with the wheel-rail contact area, and a shot original picture of the wheel-rail contact area is processed through an image processing algorithm to obtain transverse displacement data to evaluate the derailment safety level. The monitoring and early warning method based on visual behaviors is adopted to analyze the picture of the wheel-rail contact area, the method is more direct, laser ray positioning is accurate, the wheel-rail contact contour in the shot picture is clear, the number of target extraction steps is reduced, the tracking and positioning speed is high, the calculation precision is high, and the early warning efficiency and accuracy are improved.
本发明公开了一种列车脱轨安全的监测预警方法与装置,装置包括固定支架、激光仪、摄像仪,固定支架位于车轮前进方向的一侧附近,固定支架上内装有两部激光仪,激光投射角度分别定位到车轮与钢轨接触型面,在固定支架下部设置拉杆,在拉杆上安装摄像仪,摄像仪拍摄角度对准轮轨接触区域,对拍摄到的轮轨接触区域的原始图片通过图像处理算法处理,得到横向位移数据来评定脱轨安全等级。其采用基于视觉行为的监测预警方法对轮轨接触区域的图片进行分析,更加直接,激光线定位准确,拍摄图片中轮轨接触轮廓清晰,减少了目标提取步骤,跟踪定位速度快,计算精确度高,提高了预警效率和准确性。
