Relationship between dispersion circle and the range of depth of field;
弥散圆与景深范围的关系
Based on dispersion circle,a new auto focusing method is proposed.
介绍了目前常见的虹膜采集自动调焦方法,分析了被广泛应用的基于图像清晰度评价函数的方法,指出其关键指标为单峰性、灵敏度、无偏性和快速性,提出一种新的基于弥散圆的虹膜采集自动调焦方法,该方法利用主动点阵红外光源,结合可靠的瞳孔粗定位算法,不仅具有良好的单峰性和灵敏度,而且在实时性能上具有明显的优势,单幅虹膜图像平均处理时间小于1ms。
For a triangular aperture we no longer see a circle of confusion, but rather a triangle of confusion.
对于三角形光圈,我们看到弥散圈不是圆形的,而是三角形的。
The camera then paints a fully detailed picture, using an amount of light corresponding to that for each detail, spread over a disk the size of the circle of confusion appropriate for each detail in turn.
然后相机就画出详尽的图片,对于每一点使用相应的光量,扩展成一个相应弥散圈大小的原盘。
