Abstract

The invention relates to a real-time digital image enhancement method and system, belonging to the technical field of digital image processing. When processing a digital image, the grayscale image collected by an industrial camera is obtained and transmitted to a first data conversion module by a CameraLink input interface for processing. The serial-to-parallel conversion is then transmitted to the FPGA chip. The FPGA chip acts as the core processing unit and the main control unit to control the logic timing of the entire system, process the image, and then transmit the image data to the second data conversion module for further processing. After a serial-to-parallel conversion, the enhanced image is output through the CameraLink output interface. The present invention is mainly implemented by utilizing internal resources of the FPGA, and adopts a pipeline method for data processing, thereby improving the image processing speed, occupying less resources, and reducing the power consumption of the FPGA.
