Background.AOI software needs to use the OCR feature to recognize the texts on the chips. Because Our vision software are based on OpenCV and so the first choice is the text module in Opencv_contrib.Procedures.1. OCR module is not in the standard OpenCV. It's in text module of Opencv_contrib. It can downloaded from Opencv_contrib.2. The core of OCR is using tesse
I usually use a scanned copy or pdf to view documents. However, when the ipad is relatively small in text, it cannot be effectively zoomed in. It is inconvenient to move the screen every time I read the documents, to solve this problem, we want to extract text from a pdf or image, which can be effectively processed. Of course, ocr technology is required. Now we will consider and solve this problem. 1. Technical preparation: the OS is
