Method, device and system for extracting green oil circuit of circuit board

The invention discloses a method, a device and a system for extracting a green oil circuit of a circuit board, and the method comprises the following steps: analyzing a Gerber file of a target circuit board, and obtaining a green oil copper pattern region; performing area screening on the first graphic area by adopting the non-line characteristic parameters to obtain the first graphic area; carrying out region screening on the green oil copper pattern region by adopting the line characteristic parameters to obtain a second pattern region; the second pattern area is a green oil circuit area; and extracting a graph corresponding to the green oil line area to obtain a green oil line. According to the method in the embodiment, the green oil circuit area in the target circuit board can be accurately screened and extracted, and the extraction speed is high. 本发明公开了一种电路板的绿油线路提取方法、装置及系统，其中的方法包括如下步骤：解析目标电路板的Gerber文件，获取绿油铜图形区域；采用非线路特征参数对第一图形区域进行区域筛选，得到第一图形区域；采用线路特征参数对绿油铜图形区域进行区域筛选，得到第二图形区域；第二图形区域即为绿油线路区域；提取绿油线路区域对应的图形，得
