Abstract

The invention relates to a real-time digital image enhancement method and system. The invention belongs to the technical field of digital image processing. The invention discloses a method for processing a digital image. Acquiring a grayscale image acquired by an industrial camera; the data is transmitted to the first data conversion module through the Camera Link input interface for serial-parallel conversion; then, the signals are transmitted into an FPGA chip; and the FPGA chip is used as a core processing unit and a main control unit to carry out logic sequential control on the whole system, processes the images, transmits the image data to the second data conversion module to carry out serial-parallel conversion again, and outputs the enhanced images through the Camera Link output interface. The method is mainly realized by utilizing internal resources of the FPGA, and data processing is carried out by adopting an assembly line mode, so that the image processing speed is improved,less resources are occupied, and the power consumption of the FPGA is reduced.
