Abstract：To achieve more efficient and stable recognition of printed digit images,and to fully leverage the speed advantage of FPGA in parallel processing in the field of image processing,a printed digit recognition system on the FPGA hardware platform is designed.This system acquires printed images through an image acquisition module,and then optimizes image quality by using im-age preprocessing techniques such as grayscale conversion to highlight features,binarization to simplify the image into black and white,and subsequent noise removal to filter out interference.Then,it conducts precise feature matching through a digital feature recognition algorithm,and finally presents the digit recognition results intuitively through digital tubes and LCD displays.For print-ed digits,this system can achieve rapid and accurate recognition.
