Application of Chain Code Form and Line Segment Form in PCB hole detecting
Guo Bao-ping · Microcomputer Information · 2009
Aimed at researching on PCB’s holes detecting in order to adjust the benchmark of holing machine. After effective pretreatment to the image obtained by CCD, the chain code form and line segment form are used to obtain PCB holes ’ area 、perimeter、 shape and center precisely. The simulation results in by the software of Visual C++6.0 show that the PCB hole detecting could be done quickly in real time and more intelligentizedly.
