视线控制技术是通过捕捉并分析眼睛瞳孔的移动,从而达到控制交互界面的技术.该技术可以帮助残疾人士远程控制智能设备,如智能机器小车等,以扩展人们的行动和控制能力.通过对眼球追踪与控制技术的理论和技术的系统研究,设计了一个基于实现控制的模拟小车系统.该系统能够通过摄像头捕捉进行人脸识别并进一步捕捉到眼球运动行为,并对眼球的运动进行分析和数字化,从而控制模拟小车的前后左右运动.该系统主要包括人脸检测模块、眼睛检测模块、瞳孔定位模块、眼眶定位模块、位置计算模块和小车控制模块等几个模块.实验结果表明,该系统经过训练能够准确识别目标人脸的眼球运动轨迹和运动情况,并根据眼球运动能够精确控制模拟小车的运动.%The sight control technology is to capture and analyze the movement of the eye pupil,so as to achieve the purpose of control-ling the interaction interface. It can help people with disabilities to remotely control intelligent devices,such as smart cars and other de-vices,to expand people' s ability to operate and control. A simulation control system is designed based on the research of the theory and technology of eye tracking and controlling technology. It can conduct the face recognition by the camera and capture the eye movement, and with analysis and digitalization of the movement of the eyeball,can control the movement of the smart car. The system consists of several modules,such as face detection module,eye detection module,pupil positioning module,orbital positioning module,position cal-culation module and car control module. The experimental results show that it can accurately identify the eye movement trajectory and movement of the target,and precisely control the movement of the simulated car according to the eye movement.
