代码描述了可见光通信中关于光源分布的情况，不同光源分布造成屋内各个位置信噪比不同，上传了一个光源分布中心的，八个光源形成圆形分布以及最佳光源最佳分布类型。(Code describes the visible light communication information on the distribution of different light distribution caused by different house each location SNR uploaded a light distribution center, a circular eight light distribution and the best light optimal distribution type.)

Circles We can extend the Hough transform to other shapes that can be expressed parametrically. For example, a circle of fixed radius can be described fully by the location of its center (x, y). Think of each feature (edge) point on the circle as saying, ”if I’m on the circle, the center must be in one of these places”. It turns out that the locus of these votes is itself a circle. But what about circles of unknown size? In this case, we need a third parameter: the radius of the circle. So, we can parameterize circles of arbitrary size by (x, y, r). Instead of casting votes in a circular pattern into a two-dimensional accumulator, we cast votes in circles of successively larger size in a three-dimensional accumulator.
