无人机光电吊舱视频数据的实时压缩处理是无人机光电吊舱的关键技术之一。以DM368为核心处理器,以嵌入式Linux为板级操作系统,设计出一套可供无人机光电吊舱使用的低功耗视频实时压缩系统。与传统的嵌入式视频H.264软件编码压缩系统相比,本系统依赖DM368内嵌的视频协处理硬核处理H.264编码,具有功耗低、处理延迟小、外部电路简单等诸多优势。同时系统以嵌入式Linux为板级操作系统,实时性强,可稳定高效地管理视频采集、硬核调度、串口通信、数据输出等诸多任务。
The real-time compression processing of UAV optical pod video data is one of the key technologies of UAV optical pod. With DM368 as the core processor and embedded Linux as the board-level operating system, a set of low-power video real-time compression system is designed for the UAV photoelectric pod. Compared with the traditional embedded video H.264 software encoding and compressing system, the system relies on the hard-core H.264 encoding embedded in the DM368 video processing, which has many advantages such as low power consumption, small processing delay and simple external circuit. At the same time, the system uses embedded Linux as the board-level operating system and has strong real-time performance, which can manage many tasks such as video acquisition, hard core scheduling, serial communication and data output stably and efficiently.
