介绍了一种全向立体声系统的标定方法。该系统使用一对垂直排列的折反射全向摄像机,每个折反射全向摄像机由透视摄像机和双曲面镜组成,从而提供单个投影点。我们将校准分为两个步骤。第一步通过将椭圆拟合到图像中的镜边界来估计图像中心和宽高比。第二步通过使用校准图案和对极几何来估计焦距和包括比例的相机姿态(位置和取向)。实验结果表明了该方法的有效性。
This paper describes a calibration method of an omnidirectional stereo system. The system uses a pair of vertically-aligned catadioptric omnidirectional cameras, each of which is composed of a perspective camera and a hyperboloidal mirror, thus providing a single projection point. We divide the calibration into two steps. The first step estimates the image center and the aspect ratio by fitting an ellipse to the mirror boundary in the image. The second step estimates the focal length and the camera pose (position and orientation) including scale by using a calibration pattern and epipolar geometry. Experimental results show the effectiveness of the proposed calibration method.
