| 摘 要： | 为了研究列车高速运行过程中的轮轨接触状态,利用图像测量原理研制了便携式的轮轨接触状态可视化检测装置.通过钢轨内外两侧安装的高速摄像机,同步采集列车高速通过特定测量区域时的轮轨接触图像,再利用图像处理算法获得每个采样位置的轮轨外形轮廓,识别出轮轨异常接触状态,计算测量区域的轮轨接触轨迹.本文介绍了系统测量原理,重点设计了高速摄像机系统的参数,并给出了静态、动态和高速正线试验条件下装置安装可行性和检测性能的验证结果.

| Abstract: | A portable detecting device based on image measurement is developed to study wheel-rail geometrical contact state and make it visible. Two high speed CCD cameras are installed on both side of the rail to capture wheel-rail contact images synchronously while wheels passing through the inspecting area in high speed. Wheel-rail profiles are drawn out by specially designed image processing arithmetic, abnormal geometrical contact states of wheel-rail are recognized, and wheel-rail contacting track along inspect... |
