人脸人耳图像采集装置设计

Design of image capture equimpment of human face and ears

目前国内外对脱机模式下的人脸人耳图像采集装置的研究还很少,本文提出一种基于TMS320DM6437为核心的多角度人脸人耳图像采集系统。本系统采用主动式红外光源,同时设计了图像采集的机械结构。系统通过七路摄像机分时采集七幅包括人脸正面和多个角度的人耳图像并完成存储。在除了正面人脸图像外的六幅多个角度的耳图像中,必定有一个是包含人耳信息量最大的图像,通过这张图像可以完成人耳识别。本设计为人脸和人耳的融合识别提供了方便快捷的图像采集装置。

In recent times,the research of image capture equipments of human face and ears in off-PC state is not consummate in domestic and abroad.However,this paper indicates the new system based on TMS320DM6437 samples the image of human face and ears from seven different directions.In this system,active infrared light is used,and also the sampling mechanical structure is designed.The images of face and ear are sampled by multi-angle in time-sharing through seven videos,and they are saved in the system.Besides,there is an image which includes useful information of ear.According to this image,the ear can be completely identified.The design of human face and ears identify provides convenience of image capture equipment.
