基于TMS320DM368 的光电吊舱视频压缩系统设计

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.

Design of Dlectro-optical Pod Video Encoding System Based on TMS320DM368

Real-time UAV electro-optical pod video data compression is one of the key technology of UAV electrooptical pod. In this paper we propose a real-time, low-power video encoding system design, based on DM368 processor and embedded Linux operating system. Compared with traditional embedded video H.264 encoding system design, we use DM368 inner video image co-processing to process the encoding task, which has the advantage of low-power consumption, low processing delay, and simple external circuit design. Furthermore, we utilize the real-time, stable and efficient embedded Linux operating system, capable of processing multi-task, such as video capturing, hard-core scheduling, serial communication, and data transmission.
