Embodiment Construction
[0031] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0032] In the embodiment of the present invention, adopt client / server hardware topology such as figure 1 shown. The client can be connected to an image acquisition device (such as a scanner) or a hardware storage device. Therefore, the source of the image can be scanned by the image acquisition device and sent to the client, or the image file is given by the storage device and sent to the client. Client; wherein: image scanning is to scan the drawing into an analog signal through the photoelectric scanning device of the image acquisition device, and convert the analog signal into a digital image signal through the A / D converter, and the image signal is sent to the client through the USB bus;
[0033] Among them, the scanning program is started to scan the drawing through the scanning function of the vectorization system, and...
