基于ARM9的嵌入式手持瞳孔测量仪设计
Design of embedded hand-held pupilometer based on ARM9
摘要
Abstract
A kind of embedded Linux hand-held pupilometer based on ARM9 architecture is discussed in this paper. The programmed algorithm is calculated by S3C2440A chip,with which frame image of dynamic video is collected through camera and human-computer interaction is established at Qt/Embedded graphical user interface(GUI)system. Canny operator is selected for the programmed algorithm to detect the edge of eye gray image. The pupil detection is implemented by means of Hough trans-form. The experiment result indicates that the algorithm achieves the expected effect in pupil detection with high precision and low noise.关键词
