[0134] In some embodiments, if the first evaluation coefficient OPX of the target inspection area is 3, if the second evaluation coefficient TPX of the target inspection area is 5, if the preset proportional factors c1 and c2 are 1 and 1, then the comprehensive evaluation coefficient ZPX of the target inspection area calculated by the third calculation function ZPX=c1×OPX+c2×TPX is 8; wherein the proportional factors c1 and c2 are respectively the weight factors of the first evaluation coefficient OPX and the second evaluation coefficient TPX on the comprehensive evaluation coefficient ZPX, and the specific values ​​of c1 and c2 are preset according to the actual situation of the target inspection area.
