Description

family:'Microsoft YaHei', tahoma, 宋体, sans-serif;font-size:14px;line-height:22px;background-color:#FCFCFC;">从结构上来说,鱼眼镜头确实也是类似于鱼眼的结构,并且鱼眼镜头派生出两种类型,一种称为Circular Image Fisheye(圆形鱼眼),另外一种称为Full Frame Fisheye(全幅鱼眼)。圆形鱼眼是鱼眼镜头的鼻祖,其设计的视角基本在180度以上,因此画面中只能看到圆形部分,这种镜头一般拥有超大的前组镜片,且镜片弯曲度非常大(为了采集来自更多方向的光线),自然成本也极高,目前基本上已经很少有厂商继续生产圆形鱼眼镜头了,这主要还是出于成本的考虑。

关键技术

根据鱼眼镜头成像的特点,选择合适的图像畸变校正算法,标定鱼眼图像的中心和半径,用标定得到的参数进行校正,推出校正模型,方法简单。程序使用matlab 编写,效果还算可以,不过还有待改进。
