最近,图象处理引起了普遍的兴趣。人们正在试用光传感器以谋求生产线的自动化。而要把目视检查改为依靠机器自动地进行时,在模型识别问题上遇到了很多困难。在目前还是赶不上人类卓越的模型识别能力。现在,想从数字图象处理的角度来观察一下检查的自动化。 图象处理又分为印刷工程的图象处理、光学图象处理、电气模拟图象处理和数字图象处理等几种。除去印刷工程的图象处理以外, Recently, image processing has generated widespread interest. People are experimenting with light sensors to automate the production line. However, to change the visual inspection to rely on the machine automatically, a lot of difficulties have been encountered in the model identification. At present, it still can not keep up with human outstanding model recognition ability. Now, look at the automation of checking from the perspective of digital image processing. Image processing is divided into printing engineering image processing, optical image processing, electrical analog image processing and digital image processing, and several other. Apart from the image processing of a printing project,
