一种基于鱼眼图像的全景展开算法

针对在全景图像拼接技术中有着广泛应用的鱼眼图像校正问题,这里选择分辨率为800×800大小的鱼眼图片进行实验,利用鱼眼镜头垂直拍摄生成全景图的方法,运用图像像素点矩阵的变换,像素点数量的不变性,拼接其子图像,进而取得了良好的效果,由此得出了一种简单而有效的全景图展开算法。实验证明,算法简单、计算量小、实时性高、获得了良好的校正效果,达到生成全景图像的目的。

A Panoramic Unwrapping Algorithm based on Fish-eye Image

Distortion correction of fish-eye image is widely applied in the mosaic technology of panoramic image. The fish-eye picture with 800×800 resolution is chosen for experiment, and the panoramic image is vertically taken by fisheye lens, and with transformation of image pixels matrix and invariance of pixels number, its sub-images are jointed together, and a good effect is achieved. Experiment indicates that the proposed panoramic unwrapping algorithm is effective and simple, less in calculation and high in real-time performance, and thus could achieve satisfactory correction results and the penetration of panoramic image.
