摘要
设计了一种基于嵌入式Linux的矿用搜救机器人音视频系统。系统选用S5PV210微处理器作为主控单元,采用1/2.7 inch CMOS USB双目摄像头+BH1750光强采集+850 nm红外补光作为低照度环境下视频采集方案、本质安全电压转换方案和有线/无线通信接口,实现了矿井低照度环境下高清音视频的采集,并对采集的音视频数据进行压缩、存储、显示以及传输。
The audio and video system of mine search and rescue robot is designed based on the Linux.The system selects a 1/2.7 inch CMOS USB binocular camera,BH1750 light intensity acquisition and 850 nm infrared compensation light as the video acquisition scheme under low illumination environment,the hardware has intrinsically safe power conversion circuit and wired/wireless communication interface,the system realizes the acquisition of two high-definition audio and video in the low illumination environment of coal mine,and carries out compression,storage,display and transmission for the collected audio and video data.
