System and method for processing image data to generate a pavement surface evaluation and rating report

A non-transitory computer-readable medium comprising instructions for execution by a computer, the instructions including a computer-implemented method for processing image data to generate a Pavement Surface Evaluation and Rating (PASER) report for a road system, the instructions for implementing:

• collecting road data including a plurality of road images;
• identifying a plurality of features-of-interest based on the plurality of road images, each of the plurality of features-of-interest being a road irregularity in the road system;
• estimating one or more physical parameters of the plurality of features-of-interest based on the plurality of road images;
• calculating an actual location for each of the plurality of features-of-interest based on the road data;
• uniquely identifying all of the plurality of features-of-interest and eliminating duplicate occurrences of a same feature-of-interest in the plurality of features-of-interest based on the road data and the actual locations of the plurality of features-of-interest;
• identifying a corresponding road position for each of the plurality of features-of-interest based on the road data and the actual locations of the plurality of features-of-interest,
• associating each of the plurality of features-of-interest with one of a plurality of road segments located within the road system based on the road data and the actual locations of the plurality of features-of-interest;
• selecting a first road segment from the plurality of road segments as a selected road segment;
• selecting a subset of the plurality of features-of-interest that are located within a selected road segment as a selected subset;
• calculating a distance between each unique feature-of-interest in the selected subset and a nearest feature-of-interest in the first subset based on the road data and the actual locations of the plurality of features-of-interest;
• and
• generating a PASER estimation value for the selected road segment based on derived data for the selected road segment and stored baseline PASER data,
• wherein
• the road images are each associated with a corresponding road segment chosen from the plurality of road segments, and
• the derived data for the selected road segment includes the one or more physical parameters of the plurality of features-of-interest associated with the selected road segment, the actual location of each of the plurality of features-of-interest associated with the selected road segment, and the distances between the selected features-of-interest and the nearest features-of-interest associated with the selected road segment.
