光刺激下瞳孔图像动态采集系统的研发

Development of the pupil image dynamic acquisition system under light stimulation

瞳孔动态变化特性是一个不受人的主观意愿影响的客观生理参数。针对人体疲劳客观参量检测中对瞳孔动态图像采集的特殊要求,研制了光刺激下的瞳孔动态图像采集系统。主要介绍系统的组成及其设计思路,重点介绍了光刺激器原理、各模块组成及具体的设计方法。实验表明,该系统能够对瞳孔动态图像进行有效地采集,为寻找表征疲劳的特征参数奠定了基础。

The pupil dynamic characters is an objective physiological parameter, which can not be influenced by subjective motive of people. According to the special requirements of the pupil dynantic image acquisition in objective fatigue test, we have developed a pupil image dynamic acquisition system under the visible light stimulation. This paper mainly introduces the composition and design of the system and emphatically introduces the design principle of light stimulator, the modules and the specific design methods. Experiments show that the system can be effeetively used in the pupil dynamic image acquisition and lay a foundation to find the characteristic parameters of characterizing fatigue.
