Qinfeng Li, Dong Liang, Yinsong Xu, Naifu Xiao, Yilin Li · 2019
This paper improves the traditional algorithm for circuit diagram image recognition, which identifies each component as well as the topological relationship over an entire circuit diagram. This paper uses generalized nodes as the basis for analysis of the circuit connection relationship, and compares recognition speed and accuracy of the proposed method against the traditional recognition algorithm for image recognition of printed and handdrawn circuit diagrams. The comparison results show that the algorithm proposed in this paper is superior to the traditional algorithm.
