基于FPGA的红外和CCD图像融合研究及实现

为了能够同时显示多个传感器的信息，需要对红外传感器和CCD传感器获得的图像信息进行融合。通过对红外图像的插值放大、彩色编码运算，使得红外图像的分辨率和CCD图像的分辨率保持一致，并得到红外彩色图像。为了实现2幅彩色图像的融合，采用颜色空间变换的方法将颜色信息和亮度信息分离开来，采用不同的融合策略对各通道图像信息进行融合，并在 FPGA 内实现了图像的融合算法。最终设计出了一套基于 FPGA 的实时图像融合系统。

Infrared and CCD image fusion research and implementation based on FPGA

In order to simultaneously display information from multiple sensors, we need to fuse the image information that is acquired from infrared sensors and CCD sensor. This article make the resolution of infrared image is consistent with the resolution of the CCD image after the infrared image interpolation amplification, and get the infrared color images by using colour coding arithmetic. In order to realize the 2 pair of color image fusion, we adopt the method of color space transformation which can split color and brightness information and use different fusion strategies for each channel to fuse the image information, and realize the image fusion algorithm in FPGA.Finally,we design a set of real time image fusion system based on FPGA.
