摘　　要：得益于嵌入式软硬件平台的迅猛发展,可穿戴式成像设备成为发展的新趋势,并对传统便携式成像设备产生了深刻的影响。以集成了TI DM3730双核异构处理器、SDRAM、NAND Flash及电源管理的Jorjin AP模块作为处理核心,接入低功耗、小型化微光探测器和高分辨率的OLED微显示器,设计构成了应用于微光环境下目标辅助观察的嵌入式平台。平台对并行视频信号做差分对转换,提高视频传输距离和稳定性的同时,简化了视频接口线数,创新性地强化了设备穿戴的灵活性。平台算法处理能力强、功耗低、重量轻,可无线通信、视频存储及电池供电,能有效提高使用者的夜间目标探测能力,在工业、科学、军事等领域有着广泛的应用前景。Profit from the rapid development of embedded software and hardware, wearable imaging device has become a new trend and exerted a profound influence on traditional portable imaging equipments. Choosing Jorjin AP Module as the core, which integrates Texas Instruments Heterogeneous dual-core processor Synchronous Dynamic random access memory, SDRAM, NAND Flash and Power Management IC, utilizing low power consumption small size low-light camera and high resolution Organic Light Emitting Diode micro-display display, an embedded platform was designed to be applied to auxiliary target observation in low-light conditions. Platform creatively transformed video signal from parallel format into differential format, which not only improved the stability and transmission distance, but also reduced the number of physical interface＇s lines and made it more flexible to support more kinds of application scenarios. With the advantage of strong algorithm processing ability, low power consumption, light weight, wireless communication, video storage and battery powered, platform can be deeply used in improving users＇ target detection ability at night in industry, science, military and other fields.
