Abstract

The invention discloses a device for achieving image enhancement in infrared real-time puzzle by an FPGA. The device comprises an image input module, an FPGA module and an image output module. The image input module adopts a cameralink interface to acquire an infrared image, and converts a cameralink signal in a BASE mode into a line-field synchronization signal taking a pixel clock as a referenceand maximum 16-bit gray value data through a DS90CR288A serial-parallel conversion chip. The image output module writes an image into FIFO along with a pixel clock, the SDI output module reads FIFO data, splices the FIFO data into 16-bit data and sends the 16-bit data to the SDI chip, a circuit board with an FPGA as a main control chip and an image processing and collecting chip and an interfaceas peripheral circuits serves as a hardware structure, programming is conducted on the FPGA in a hardware description language, and real-time image frame-by-by-frame enhancement is achieved. Accordingto the technical scheme, the problem of poor imaging quality in the prior art is effectively solved.

Description

technical field [0001] The invention relates to the technical field of image enhancement, in particular to a method for FPGA to realize image enhancement in infrared real-time mosaic. Background technique [0002] Infrared imaging technology has significant advantages in target detection, identification, tracking and many other aspects, so it is widely used in border defense, weapons, monitoring and many other fields. Because of its wide range of applications, the performance of thermal imaging cameras has also improved. At present, high-precision thermal imaging cameras can generally achieve 14-bit or higher precision to meet the requirements of image processing algorithms. For different scenes, the grayscale distribution of infrared images is not the same, and may be distributed in a small range, resulting in problems such as inappropriate contrast and poor imaging quality. Contents of the invention [0003] The purpose of the present invention is to provide an FPGA de...
