全景拼图的实现技术

为了成功地实现360°无缝全景拼图,分析研究了图像拼接的现有理论,将基于灰度图像的求灰度值最小误差的方法应用于现实中的彩色图像,实现了图像的配准;并应用图像边缘检测技术,对图像配准的传统方法进行了改进,有效地提高了图像配准的精确度.同时,从理论上探讨了图像缝合技术中色差线性调整这一方法的不足,分析了图像缝合后横向条纹出现的原因,并提出图像中值的色差线性调整方法,消除了图像缝合后的横向条纹.

Research on the Realization Techniques of Panoramic Image Merging

In order to realize successfully 360°seamless panoramic image merging, the authors deeply analyze and study the existing theory of image merging and apply the method of finding the minimum error of gray value based on gray images to the colour images in reality so as to realize the image registration. The image edge determination technique is appcied to improve the traditional method of image registration so that its exactness is effectively enhanced. The difficiency of linear adjustment of colour difference in image stitching is theoretically discussed and the cause of the appearance of horizontal stripes after image stitching is analyzed. Finally, the authors propose the effective linear adjustment method of colour difference to eliminate the horizontal stripes after image stitching.
