摘　　要：鱼眼镜头具有短焦距、大视场的优点,因而在很多领域都得到非常广泛的应用,但存在鱼眼图像畸变比较严重的问题,这就需要对图像畸变进行校正.为此,提出了一种能够实现全视觉球面图像的摄像机,并且给出它的标定方法.实验结果说明,根据给出的球面图像摄像机模型,图像畸变得到校正,并且也实现了球面摄像机对车辆周围环境的监测.The fisheye lens is widely used in many fields because of its short focus and wide field of view. But fisheye lens leads to serious image distortion that is required to be corrected. For this purpose, a camera which can generate a full vision spherical image was proposed in this paper, and its calibration method was provided. Experimental results indicate that the image distortion can be corrected with the presented prototype of the spherical camera. With this camera, we conduct the monitoring to whole surroundings around a vehicle.
