摘要
红外热成像系统的输出图像非均匀性比较明显,成像模糊,因此研究针对红外图像的锐化增强算法,具有比较重大的意义。一种新的红外图像组合边缘算法在软件仿真上的有效性已经探讨过,在此基础上,对算法稍作改进,重点探讨该算法在硬件实时图像锐化增强上的有效性。为此,设计FPGA+SRAM的硬件结构,探讨该算法在硬件系统上的实现方法,分析该算法在硬件平台上的实施效果,比较该算法在软件仿真和硬件实现上的实施效果。图像经过该锐化算法实时处理后,轮廓得到加强,易于识别图像目标。验证了改进锐化算法的有效性。
The output of the infrared imager is heteropical and dim,so the sharpening enhancement algo rithm of the infrared image has the great significance.The effectiveness of the algorithm of infrared image com bined the edge has been discussed in the software simulation,on that basis,the algorithm has a few improve ments.The effectiveness of the algorithm in the sharpening enhancement about the hardware real-time image is mainly discussed.The FPGA ＋ SRAM hardware structure is designed,the realization method of the algorithm in the hardware system is discussed,the effect of the algorithm realized on the hardware platform is analyzed,and the implementation effects between the software and hardware are compared.The image contour is strengthened after the sharpening algorithm and the objective is identified easily.
