A Method to Measure Depressed Pavement Area Based on Single Image

Abstract:

A calibrated plate will be placed on the spot before digital pictures are taken to calculate all kinds of useful data with a distance measure system of traffic based on single view. Depressed pavement area such as groove, gasoline stained etc. can be measured based on a single view, a method which employs region growing and boundary tracking was given in this paper. Firstly a closed boundary can be achieved with algorithm of region growing and boundary tracking, furthermore the pixels within the target closed area can be calculated. Finally the practical area can be calculated through the ratio relationship between the area and the calibrate plate. The experiment shows that the method has low time complexity and high robust．
