| 摘 要： | 要从鱼眼图像恢复出实际的场景图像,其前提是必须准确的提取出鱼眼图像的轮廓,而提取鱼眼图像的轮廓也就是确定鱼眼图像的中心和半径.从提取鱼眼图像轮廓着眼比较了最小二乘拟合法、面积统计法、扫描线逼近算法、改进的扫描线逼近算法等各自的优缺点.其中改进的扫描线逼近算法具有准确地提取鱼眼图像轮廓,计算量小,实时性好,校正效果好的特...

| Abstract: | To resume actual image from fish eye image,the Precondition is contour extraction of fish eye image truly.At the same time,contour extraction of fish eye image is also to find the center and radius of fish eye image.This paper is to compare calculating the area of the square method,the circular region,scan line approach algorithm and the improved scan line of approach algorithm.The improved scan line of approach algorithm has the advantage of veracity,the less calculate amount,the good real-time and the fin... |
