由ＣＣＤ摄像装置、视频信号采集卡和个人计算机构成的眼球活动分析系统能实时地跟踪、分析病人眼睛凝视点的变化规律．本系统应用图像分割和快速边缘检测技术精确测定眼睛注视位置，根据预定准则分析凝视点的空间和时间分布，为精神病临床检查和医学研究提供了重要依据．文中给出了一个凝视点分析实例
The eyeball activity analysis system composed of CCD camera, video signal acquisition card and personal computer can track and analyze the changing rule of the patient’s eye gaze point in real time. The system uses image segmentation and fast edge detection technology to accurately measure the position of eye gaze and analyze the spatial and temporal distribution of gaze point according to predetermined criteria, which provides an important basis for clinical examination and medical research of mental illness. The article gives an example of the point of gaze analysis
