摘　　要：为提高无人机在作战时通过无线电实时下传侦察图像目标位置提取设备的通用性与实时性,设计了以TMS320DM642为核心CPU,外围扩展图像编解码、遥测数据接收、操纵杆位置采集等电路所构成的一套硬件平台系统。在软件方面,采用空间三维坐标多级转换的方法解算目标位置,并通过修改内存数据将目标坐标值叠加于侦察图像中。经过多次飞行验证,该系统能够将目标坐标值叠加在侦察图像中的目标附近,且定位精度满足用户要求。In order to improve the versatility and real-time performance of target location extraction equipment when UAV is used in combat to download real-time reconnaissance image by radio,in this system,the core CPU of TMS320DM642 was used and the hardware platform of the system was constructed by expanding the image encoding and decoding circuit,telemetry data receiving circuit and joystick position acquisition circuit outside the CPU.In terms of software,the multi-level transformation of spatial three-dimensional coordinates was used to solve the target location,and the target coordinates were superimposed on the reconnaissance image by modifying the memory data.After many flight tests,the system can superimpose the target coordinates near the target in the reconnaissance image,and the positioning accuracy meets the user’s requirements.
