Real-time pupil detection and tracking method

Abstract

The invention discloses a real-time pupil detection and tracking method. The method includes: (1) adopting a camera to shoot facial images in real time; (2) adopting an image capture card for capturing video images to obtain a sequence of a group of images; (3) subjecting each frame of captured images to skin detection to determine whether a human face exists or not and judge an approximate area of the human face; (4) detecting a pupil position in the area of the human face and tracking. By a YCbCr color space based skin color model, the method is high in detection rate under conditions of different skin colors and large illumination changes.

Description

technical field [0001] The present application relates to the technical field of safe driving of automobiles, and in particular, to a real-time pupil detection and tracking method. Background technique [0002] Pupil detection is proposed as part of face recognition. Regarding pupil detection, although many people at home and abroad have put forward different views, the current mainstream methods include template matching method, projection method, "feature eye" method, method based on wavelet transform, method based on symmetry and method based on neural network . [0003] Kanade and other researchers have developed methods to detect pupil features from a static image. More pupil feature detection methods are based on YUlll's irregular template method, but since the irregular template scheme requires a lot of time, this The method is difficult to apply to pupil tracking in video images. But if used for pupil tracking, these schemes are far from meeting the real-time requ...
