基于YUV空间色彩传递的可见光/热成像双通道彩色成像系统

实现了基于DSP/FPGA的可见光与热成像双通道图像实时融合系统。选用Altera公司的Cyclone II FPGA首先对可见光和红外热图像进行彩色融合，再利用TI公司的TMS320DM642实现YUV空间的色彩传递，将白天光照下彩色图像的颜色信息传递给融合图像，使其更接近自然色彩，尽可能反映出更丰富的场景信息。文章阐述了系统原理、特点和功能，经实验证实，本系统可以实时实现树林、陆地背景下有效的色彩传递。

A Dual-band Color Imaging System for Visible and Thermal IR Images Based on Color Transfer in YUV Color Space

A dual channel real-time image fusion system based on DSP/FPGA for color night vision was designed. The visible and thermal IR images were fused into a color image through Cyclone H FPGA made by Altera Co. Ltd.，the color transfer in YUV color space was executed by TMS320DM642 made with TI Co. Ltd.，to transfer the color information of a day-time target image to the fusion im?age, which more approaches nature color and possibly reflects rich scene information. The principles, the structure, characters and the functions of the system were expounded. It was proved Dy an experi?ment that the system can realize effecive color transfer in real time against the background of woods and land.
