摘要：In order to evaluate thedamage of the road accurately, a Ferret subsection measurement method based on Invariantmoment was proposed.First, it set a Ferret minimum external rectangular on the basis of the barycenter and spindle. The rectangular width was the result of crack width.It settheedge conditions for reducing the errors of measurement caused by the slender burrs. It allowed rectangular edge and targets to intersect. In order to section reasonably, a method basedon distance map was proposed. In the extreme value points, the subsections image was finished. It ensured that the distance between two adjacent lines was longer thanthe crack width. Experimental data indicated that the percent of valuable information was higher, the measurement was accurate. It can meet the requirement of practical engineering.
