全景环形透镜三维空间成像展开算法的研究

全景环形透镜(PAL)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,极大地限制了PAL的应用领域。现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,极大地拓展了PAL的应用领域。

Research on image processing of the three-dimensional image of panoramic annular lens

Panoramic annular lens(PAL) is based on the principle of flat cylinder perspective(FCP),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.
