【摘要】 全景环形透镜PAL(Panoramic Annular Lens)利用平面圆柱投影法(FCP),将三维空间的像成在一个环形区域,由于其成像原理不同于人眼习惯的中心投影法(CCP),故不利于人眼的观察以及测量,极大的限制了PAL的应用领域。本文提出了一种新的展开方法,实现了从FCP到CCP 的转换,结果表明,三维立体空间环形像的展开效果良好,更符合人的观察习惯,极大的拓展了PAL 的应用领域。更多还原

【Abstract】 PAL(Panoramic Annular Lens) is based on the principle of FCP(Flat Cylinder Perspective), it images the three-dimensional space around its axis onto a two-dimensional annular space. For the principle it based on is FCP, which is different from Central Convergence Perspective(CCP) , the way human use to view the world. So the image of PAL doesn’t suit with our human, thus limits the usage of PAL, In this article, a new image process method is provided by the method of changing the principle of FCP to CCP, and expands the use of PAL into the three-dimensional space, makes it possible to the fields of endoscope, navigation, robot vision and large-scale inspection.更多还原
