摘要： A system and method are provided for monitoring an eye to determine eye closure. The system includes a video imaging camera oriented to generate images of an eye, and a video processor for processing the images. The processor includes an edge detector for detecting edges of the eye in the image, and a line selector for generating lines at any of select angles representative of the detected edges. The processor determines the state of eye closure, such as an open eye or closed eye, based on an angle between two of the lines that select angles. The system may be employed on a vehicle to determine the eye closure state of a driver of the vehicle.

摘要： A system and method are provided for monitoring an eye to determine eye closure. The system includes a video imaging camera oriented to generate images of an eye, and a video processor for processing the images. The processor includes an edge detector for detecting edges of the eye in the image, and a line selector for generating a plurality of lines at multiple angles representative of the detected edges. The processor determines the state of eye closure, such as eye open or eye closed, based on the number of lines at selected angles. The system may be employed on a vehicle to determine the eye closure of a driver of the vehicle.
摘要翻译：提供了一种用于监视眼睛以确定眼睛闭合的系统和方法。该系统包括面向产生眼睛图像的视频成像摄像机和用于处理图像的视频处理器。处理器包括用于检测图像中的眼睛的边缘的边缘检测器，以及用于以表示检测到的边缘的多个角度生成多条线的线选择器。处理器基于所选择的角度的线数来确定眼睛闭合的状态，例如眼睛打开或眼睛闭合。该系统可以用在车辆上以确定车辆驾驶员的眼睛闭合。

摘要： A system and method are provided for monitoring an eye to determine eye closure. The system includes a video imaging camera oriented to generate images of an eye. The system also includes a video processor for processing the images generated with the video imaging camera. The processor includes an edge detector for detecting edges of the eye in the image and a line selector for generating substantially horizontal first and second lines representative of the detected edges. The processor determines the state of eye closure, such as eye open or eye closed, based on distance between the first and second lines. The system may be employed on a vehicle to determine the eye closure of a driver of the vehicle.
