Grooved texture depth detection algorithm for cement concrete pavement

The invention discloses a grooved texture depth detection algorithm for a cement concrete pavement. The grooved texture depth detection algorithm comprises the following steps: inputting a three-dimensional data matrix of an image, and performing filtering processing on data; performing partitioning processing on the three-dimensional image data matrix after filtering, and dividing the data matrix to N uniform blocks according to the size of the matrix; calculating the corresponding texture depth of the block one by one; and calculating the mean texture depth one block by one block, and calculating an arithmetic mean of the N mean texture depths, namely the texture depth value TD of the image. According to the grooved texture depth detection algorithm, the real-time, high-efficient and quantitative detection of skid-resisting capacity of the cement concrete pavement can be realized. The method provided by the invention has the advantages of simplicity in calculation and short operation time, and is suitable for being used in a real-time system. According to the method provided by the invention, human intervention is not required, surface measurement is adopted, the efficiency of the method is high and the detection is precise; the influence of an inclined plane is eliminated, and the range of applications is wide, and potent information support can be provided for maintenance and management of the cement concrete pavement, and the maintenance and management level of a highway is improved.
