| As an important node in the battlefield information network, solo combat system plays a key role in the information war. Its leading pattern of combat mission will change from the traditional destruction to with reconnaissance and leading attack. The wireless video transmission system based on bluetooth is the result of individual terminal reconnaissance system. It applies bluetooth technology to military and can short the real-time monitoring of battlefield. It is important to enhance battlefield perception of the transient soldiers.This paper designed a set of embedded wireless video transmission system based on bluetooth after study and comparison of military wireless video transmission method and key technology at home and abroad. Designed the camera acquisition module based on OV5640. Designed the bluetooth transceiver module based on MT6620. Optimize and improve the hardware interface of bluetooth and camera to improve interface conversion rate in view of the battlefield applications. Based on the Bluetooth protocol stack, transplant and optimize the driver of the Bluetooth module. Based on the V4L2, transplant and optimize the driver of the camera module. And implement the bluetooth wireless video transmission system.Aiming at the problem of wireless video transmission highly delay, this paper adopted the MFC codec hardware and TCP/IP transmission joint solutions to reduce delay. Adopted based on bluetooth macroblock level adaptive bit rate allocation algorithm in terms of rate control. It leads to lower latency and video quality. Design the double thread control algorithm and reduces the system delay.Test and analysis system delay, PSNR, packet loss rate after design wireless video transmission system. Using normal terminal software system for function test and analysis. It Mainly test the video resolution, transmission distance, video quality and anti-jamming. Test results meet expectations. So it has extensive application prospect in military field.
