摘　　要：提出了一种利用扫描变换技术实现的水平视场角为180°的全景电视系统。通过将电视摄象机的直线扫描变成圆扫描,可以在一个普通的电视监视器上同时观测展开的360°全景图象,该系统具有观测场面大,图象连续完整,直观性好,易辨别图象方向等优点。通过实验研究,给出了全景电视的一种电路实验方案。最后,通过摄取模拟图象,在监视器上显示出了展开的360°柱面图象。In this paper, a panoramic TV system with a horizontal viewing angle of 180° by utilizing scan converting technology is proposed. By converting linear scan of a TV camera into circular scan, the spread 360° cylinder picture can be observed on an ordinary TV monitor simultaneously. As a result, the viewing angle is enlarged, the scene is displayed with continuity and completeness, the reproduced picture is convenient for direct—viewing and for recognizing the direction, etc. An experimental scheme of the panoramic TV system is given by experimental investigation and the spread 360° cylinder picture taken from the monitor for a simulate.d picture is shown in this paper.
