摘　　要：基于双曲面折反射镜的全方位视觉传感器(ODVS)具有采集速度快、制造成本低、固定单视点成像等特点,已逐渐成为新一代全景图像获取的重要装置;文中利用4台具有相同成像参数的ODVS在同一水平面上以人眼间距对称配置,从4个不同视角实时采集水平360°范围内的全景立体图像;实验结果表明,文中设计的全景立体摄像装置在10m范围内摄取的全景3D图像富有立体感,具有成本低廉、操作简便、便于空间几何计算、符合人眼视觉习惯等诸多优点,具备较为广泛的应用前景。Omni--direetional vision sensor （ODVS） based on hyperbolic mirror is showing its rising importance among the new genera tion of panoramic picture capturing devices for its characteristics like high--rate data acquisition, low manufacturing cost, fixed single view point and so on. In this paper, we use four same ODVS to be symmetrically set on one plane with the spacing of human eyes to capture panoramic pictures from four different angles, thus to build a new kind of panoramic stereo camera which is capable of capturing 3D pictures in a horizontal range of 360 degrees. Experiments results show that, based on the characteristics of low--cost and user--friendly control, the camera is also qualified to capture panoramic 3D video fitting human visual habit as well as full of good stereo impression especially within the distance of 10 meters, and get depth information with simple geometry computation. This device has a promising future to be widely used in many fields.
