Device and method for detecting thickness of water film on road surface
The invention discloses a road surface water film thickness detection device, which comprises an outer cover, the bottom of the outer cover is open, and the bottom of the outer cover allows water flow to flow through smoothly; the water film thickness detection structure is arranged in the outer cover, the water film thickness detection structure is a coating capable of changing color when encountering water and coated on the supporting structure, and after the bottom end of the supporting structure is in contact with the road surface, the color change length of the coating capable of changing color when encountering the road surface water is the water film thickness value; the pavement texture image acquisition device acquires a pavement texture three-dimensional cloud picture of the detected area and transmits the pavement texture three-dimensional cloud picture to the data processing module, and the data processing module recognizes a pavement texture depth value of the detected area according to the pavement texture three-dimensional cloud picture of the detected area. And the actual water film thickness value is obtained by subtracting the pavement texture depth value from the color change length of the water-discoloring coating. The device is convenient to carry and can be used and measured immediately, the calculation complexity is reduced, and the obtained water film thickness value is measured accurately.
本发明公开了一种公路路表水膜厚度检测装置，包括：外罩，外罩底部开口设置，且外罩底部允许水流畅通流过；水膜厚度检测结构，水膜厚度检测结构设置在外罩内，水膜厚度检测结构为涂覆在支撑结构上的遇水变色涂层，支撑结构底端接触路面后，遇水变色涂层遇到路表水发生的颜色变化长度即水膜厚度值；路面纹理图像获取装置，路面纹理图像获取装置获取被测区域的路面纹理三维云图，并传送到数据处理模块，数据处理模块根据被测区域的路面纹理三维云图，识别被测区域的路面纹理深度值，进而利用遇水变色涂层的颜色变化长度减去该路面纹理深度值，即为实际的水膜厚度值。装置方便携带，可以即用即测，降低了计算复杂度，得到的水膜厚度值测量精确。
