利用HDL Coder完成红外探测器图像死点的替换

Dead Pixel Replacement in Infrared Detector Imaging System Using HDL Coder

利用HDL Coder工具从基于simulink模块的设计中生成可综合的硬件描述语言,并用FPGA实现红外探测器图像数据流的死点替换。以非致冷红外探测器成像系统中的死点替换为例,阐述了这一开发流程。将开发的关注点从HDL代码的底层编写转移到系统构架算法和仿真等更高级别的设计上来,提高了开发效率,并且取得了很好的图像处理效果。

Firstly,the synthesizable hardware description language（HDL）codes are generated in the design based on a simulink module by using the HDL Coder.Then,the FPGA is used to implement the dead pixel replacement in the image data stream of an infrared detector.By taking the dead pixel replacement of an uncooled infrared imaging system for example,the development process is described. Because the concerns are transferred to the upper design levels such as system architects and simulation, the development efficiency is improved and good image processing effectiveness is obtained.
