摘要
分析了对海红外成像特征以及图像处理的技术难点。设计了一种海空背景下对舰船目标进行自动识别和跟踪的图像处理系统。首先,介绍了采用目标跟踪和识别算法并行工作的软件设计,该设计充分融合跟踪和识别处理信息。然后介绍了基于双DSP和FPGA构架的硬件设计,以DSP作为核心处理单元,FPGA作为控制单元。最后给出了外场试验实验数据,验证了该红外图像处理系统具有良好的实时性和适应性。
The characters of IR image under sea and the technical difficulties of image processing of which are analyzed. An infrared image processing system, which could automatically detect and track ship targets under sea and sky background, is introduced. First, the design of system software based on parallel processing of target tracking and detecting algorithms is introduced. The design fully fuses the processing information of tracking and detection model. Then, the system is implemented on the framework of double DSPs and FPGA. In the system, DSPs are used as core processing units, and FPGA is used as control unit. Finally, the practical experiments demonstrate the infrared image processing system has good real-time performance and adaptability.
