摘要:
针对目前不同光谱波段图像配准算法复杂、精度低和实时性差的问题,该文提出了基于像素空间相关度的双通道图像融合效果评价方法,将该指标用作实时图像配准的控制参数,在基于DM642的视频图像实时处理仿真平台上,对微光双谱图像进行了实时配准。实验结果表明:与常用的基于控制点、边缘等图像配准算法相比,该文提出的实时配准方法准确、有效,且不受图像灰度变化、噪声及不同微光成像波段成像器的光谱响应特征的影响。
Abstract:
In view of the problem of the complexity of different spectrum image registration arithmetics,low registration precision and bad real-time property,an evaluation method of the dual-channel image fusion effect based on pixel spatial correlation degree is proposed.This index is used as the control parameters of real-time image registration.Dual band real-time image registration is carried out based on real-time video image processing emulational platform based on DM642.The experimental results show that,compared with the commonly used algorithm based on the control point or the edge,the image registration algorithm proposed here is more accurate and effective,and it is not influenced by image gray scale change,noise and spectral response characteristics of different band low level light imaging device.
