Research And Implementation Of Fatigue Detection Software System Based On Multidimensional Chaotic Encryption

Fatigue driving is one of the most important factors that cause traffic accidents.Fatigue detection is an effective way to reduce traffic accidents.There are inevitably image information security issues during the network communication process.Image encryption is an effective way to solve the problem of information security.It is an issue worthy of further study to ensure the information security of the collected image in the network communication while the driver fatigue detection,this paper investigated these two aspects in detail.In this paper,based on the Visual Studio 2010 integrated development environment,MFC class library and OpenCV open source visual library,we design a fatigue detection software system based on multidimensional chaotic encryption.Through the analysis of image encryption technology and using multidimensional chaotic encryption algorithm encrypts video image,we proposed multi-threading method for the encryption so as to improve the real-time image encryption and using package transmission method so as to improve the real-time video transmission process;During the fatigue detection process,by combining with the Haar-like rectangle features in OpenCV classifier for face detection,eye location using sliding window and Hough transform based on human face detection in the region,and finally judged the fatigue,the whole process of the fatigue detection was presented in this paper.There are client and server(C/S)endpoints designed in this paper,the fatigue detection and image encryption are realized on the server side,the image decryption and video display functions are implemented on the client.Finally,through the test verification,the expected goal was achieved.
