| With the development of control science,computer science,electronic science and other subjects,the research on face detection system has made many achievements.However,at present,most face detection systems are based on the PC architecture,and their portability and mobility are greatly limited.So,it is very inconvenient to use them in some special applications.Under this background,new requirements have been put forward for face recognition applications.Therefore,researches on embedded system face recognition have very strong practical significance and broad application prospects.Under this background,this paper designed and implemented an embedded face detection system based on OpenCV.Based on the Windows CE6.0 operating system,this system used EVC4 development tools for development,accepted the S3C6410 development board and the OV9650 camera as the hardware of the system,and employed face detection algorithm which was based on Haar-like feature and Adaboost cascade to detect faces.In this paper,the current research situation of embedded face detection system was analyzed,and then the porting process of OpenCV was discussed.On this basis,the demand analysis and overall design of face detection system based on OpenCV were conducted;the face detection algorithm used in the system was studied;and the system development platform was introduced in detail.On this basis,this paper realized the face detection system based on OpenCV,and described the implementation methods of image acquisition module,the face detection algorithm and other modules detailedly.Finally,the performance of the system was tested.After testing,the system could operate correctly and efficiently to achieve the purpose of system development.The face detection system based on OpenCV has been put into practical use.Embedded face detection system can overcome the shortcomings of traditional face detection system in its portability and mobility.Also,it can detect the face correctly and efficiently,and promote the promotion and application of face detection system. |
