摘要
提出了基于图像映射实现球面全景空间缝合及实时浏览的算法。首先,对两幅或多幅鱼眼图像使用扫描线逼近算法分别提取轮廓,再采用基于亮度差的图像缝合算法对其球面投影进行球面缝合,使用球面坐标定位校正算法校正图像并拼接成平面全景图,通过建立球面浏览视窗与平面全景图之间的像素映射关系,显示球面全景空间不同视角场景信息。实验结果表明,该算法较好地实现了鱼眼图像的无缝拼接以及球面全景连续360°的实时浏览。
A new algorithm was carried out to realize the reconstruction and navigation of sphere panorama. Fisheye image outline was picked up by using the scanning beam algorithm and its sphere projection was stitched with another one by using the lightness dispersion algorithm. The distortion of two fisheye images were corrected and then stitched to a plane panorama. Pixel mapping connection was fixed on between the scan window and the plane panorama, which realized a movement of view angle in all directions. The experiment shows that fisheye image stitching is realized and the sphere panorama navigation in the range of 360 degree can be done.
