基于序列图像的全景图像拼接

Panoramic image mosaic based on sequence image

基于图像建模和绘制的虚拟环境构造是近年来虚拟现实技术研究的热点。其中基于序列图像的全景图像拼接技术研究是虚拟环境临场感的一个关键因素,文章以普通照相机拍摄的序列图像为基础,通过相邻两幅序列图像差值图像极值点的搜寻,可以快速提取两幅序列图像之间的重叠部分,并采用线性加权法使得缝合后的图像自然、逼真。最后给出了本算法在PC机拼接的效果图。

Virtual environment building based on image modeling and rendering is the hot point of the research on virtual reality technology,and the panoramic image mosaic technology based on sequence image is a key to achieve virtual environment telepresence. In this paper,the sequence images taken by using ordinary digital camera are used and the differences of two adjacent sequence images are calculated in search of the minimum point,then the overlapping part between the two sequence images can be obtained fast. By adopting the linear weight method,the mosaic image is made more natural and lifelike. The mosaic image realized on the personal computer is also given to show the effectiveness of the presented algorithm.
