摘要
分析了当前的高速公路路面检测仪的不足,提出了一种基于几何光学三角测量原理的高速公路路面车辙检测系统。针对本仪器采集的图像数据的特点,采用非线性中值滤波对图像实时处理取得了满意效果,实验测试表明整个系统对路面起伏的分辨率达到毫米量级。
The paper has analyzed the deficiency of the speedway road inspecting instrument. A new design based on geometrical optics triangulation for the instrument has been presented. According to the charaeteristies of the image data captured by the system, we completed the image manipulation effectually by no - linearity noise filter. The experiment showed the system could detect 1 mm change of the road surface.
