Fixation Points Estimation Based on Binocular Stereo Vision
Pages 71 - 74
Abstract
This paper proposes a method of fixation points estimation combining the two-dimension mapping model with three-dimension stereo vision. The purpose of our study is to design an easy-to-use non-contact gaze tracking system under natural light. The method of two-dimension mapping is easy to achieve, however, it needs the user to keep the head being fixed. It could achieve higher estimation accuracy though it is still not easy for users to use the algorithm. To solve this problem, we have introduced the binocular cameras to calculate the pose of head and then add the related result into the result of 2D mapping to compensate the movement of head. The average error angles of gaze estimation in the case head fixed and head moving are 5.1°and 8.5°, respectively. This proposed method is easy to achieve and the experiment device is easy to mounted.

Remote gaze estimation based on 3D face structure and iris centers under natural light
Remote gaze estimation under natural light is still a challenging problem. Appearance based methods are seriously sensitive to illumination variation in the visual spectrum and usually can hardly handle the problem of head movements. And most existing ...
Binocular Camera Calibration Using Rectification Error
CRV '10: Proceedings of the 2010 Canadian Conference on Computer and Robot VisionReprojection error is a commonly used measure for comparing the quality of different camera calibrations, for example when choosing the best calibration from a set.
