基于机器视觉的人眼跟踪系统的设计和实现 - 图文

摘要

摘要

随着人机交互技术的不断发展，除了传统成熟的鼠标、键盘等输入方式外，语音输入也进入了实用化阶段，人眼视线由于其本身包含较多当前任务信息也自然成作为一种候选的输入通道。

目前对于人眼视线的人机交互技术研究渐渐受到人们的重视。本文就人眼视线的人机交互技术，将当前比较成熟、完善的机器视觉技术与虚拟仪器相结合，利用市场上比较常见的摄像头对人眼进行非接触式的图像采集，由LabVIEW和Vision Assistant以及IMAQ Vision组成的虚拟仪器，对采集的图像进行处理和识别。最终建立人机交互平台，并完成人眼视觉对电脑鼠标控制的人眼追踪系统。

本系统是将机器视觉与虚拟仪器相结合，完成人眼视线与机器人机交互的一次新的尝试，是一个较有价值的研究方向。

Abstract

Abstract

With the development of Human-Computer Interaction Techniques, except the traditional mouse and keyboard, voice input method has entered practical stage. Because of the human sight includes a lot of information of current tasks, it can naturally becomes a candidate input channel. Human-Computer Interaction Techniques research about human sight is becoming more and more important.

In this paper, our method is based on the Human-Computer Interaction of human sight to combine mature machine-vision and virtual instruments. We used the camera which can be easily found on the market to gather the images of human eye by untouched way and the virtual instrument which consist LabVIEW, Vision Assistant and IMAQ Vision to process and identify the gathered images. At last, we had built Human-Computer Interaction platform to accomplish eye tracking system which uses human sight to control computer mouse.

This system combined machine-vision and virtual instruments to accomplish a new try of Human-Computer Interaction of human sight and computer. This is a valuable research field.
