Research on matching method based on structural characteristics of profile surface
In view of the difficulties in drawing reuse after aluminum extrusion die design and the low efficiency of finding similar profile surface dies,a matching algorithm based on the structure characteristics of profile surface was proposed.According to the new profile surface image match-ing database of similar profile surface images,the corresponding die design was found for refer-ence.It used YOLOv5 algorithm to effectively identify the structural features of the profile surface and automatically mark the structure position.By calculating the position,acreage,and type of the corresponding structure on the profile surface,the structure similarity was obtained,and the struc-ture was matched one-to-one according to the idea of minimum cost and maximum flow to obtain the best matching result.
