问题描述
因此，认为这是我想建立一个软件谁可以跟踪学生的possition，但我不能找到在互联网上的数学aproch的问题。我想看看如何计算瞳孔的位置的一些例子。谢谢！
So, the think is i want to build a software who can track the possition of the pupil, but i cant find on internet a mathematical aproch to the problem. I want to see some examples of how to calculate the position of the pupil. Thanks!
推荐答案
我认为最常见的方式包括照明与点光源的主体和使用明亮的高光在角膜上找到眼球。然后，相对于亮点瞳孔的位置，让你的方向。要使用红外光和红外线黑白摄像机简化图像处理。
I think the most common way involves illuminating the subject with a point light source and using the bright specular highlight on the cornea to locate the eyeball. Then the location of the pupil relative to the highlight gives you the direction. To simplify the image processing you use IR light and an IR monochrome camera.
要制定出数学尝试用一个圆形的眼球素描它在2D，创建镜面高光，其中光眼的中心之间的线穿过圆一个固定的点光源和阴影弧再present瞳孔。
To work out the math try sketching it in 2D with a circular "eyeball", a fixed point light that creates the specular highlight where a line between the light and the center of the eye crosses the circle, and a shaded arc to represent the pupil.
