| 摘 要： | 全景环形透镜(PAL)独特的成象性能,即环绕光轴360°产生一个环形象且景深为无穷远,使得由PAL组成的观测系统没有活动部件能同时观察透镜周围的景物.但PAL所成的环形象不便于人眼观察和测量,有畸变、失真,为此,本文根据图象坐标变换,实现了一种环形象的线性恢复,即首先将环形象线性化处理,再对其进行插值,实验结果表明线性化效果较好.该图象处理技术可以为发挥PAL的许多潜在应用创造条件.

| Abstract: | For the special imaging feature of Panoramic Annular Lens,that forming an annular image circling the axis and having endless depth of field,the observing system made up of PAL can be used to observe object around the lens without moving part.But the annular image formed by PAL is not only unconvenient for observation and measurement,but also has distortion phenominon.According to coordinate convertion of image,a method of linearizing annular image is presented.The results show that the effect of linearization is good.With this method,it can be found basis for potential application of PAL. |
