摘　　要：图像的边缘是图像的最基本特征之一。边缘检测可以应用在基于特征相关的图像配准方法中。根据在紫外检测中可见光与紫外图像配准、融合的实际需要,利用双光谱图像检测系统,在TMS320DM642评估板上用Sobel算子实现了对可见-紫外图像的边缘检测,为系统的图像配准提供了边缘检测的方法。The edge is one of the most fundamental features of image. Edge detection can be used in the image registration which based on the feature＇s correlation. Edge detection has been realized for needs of visual and UV image registration as well as fusion for UV detection. It uses arithmetic operators Sobel based on U/V double spectrum imaging system and high speed DSP TMS320DM642 EVM, which can be applied in image registration.
