Reverse Engineering Printed Circuit Board is to obtain the schematic diagram based on the board image. The key technologies involved are image processing, image recognition, component and line connection processing, network table generation and automatic generation of schematics.
The study is focusing on the component and line connection processing techniques in the network table generation process. Specifically, component and wire processing technologies include Protel component library analysis, component symbol and various component connection processing algorithm design, invisible line analysis reasoning, and network table generation.
