Accordingly, it is necessary to develop a drowsy driver awareness system. To avoid interrupting the driver, it is necessary to build a system under non-invasive and non-contact condition. Image process system suits to achieve such a request. Hence, it is recommended to judge the drowsiness state by observing eye status of operators via eye video. In this thesis, we use a CCD camera as the image sources and use skin color map to segment skin region. Then we use PCA algorithm to find the eye region for circular template searching. The circular template will locate the iris region and finally we can analyze this region to classify the eye openness state. By numerical simulation, we have obtained a high accuracy on eye openness detection and it would be helpful for the drowsy detection system.
