摘要
分析了车载视觉增强系统中红外热成像的特征及其图像处理的技术难点, 并设计了一种车载红外热成像图像处理系统。首先, 在评估了系统的静态资源和动态资源的消耗后, 给出了以 FPGA为核心处理单元、ARM为控制单元的系统硬件架构。然后介绍了图像处理系统的软件设计, 并提出了一种用于系统调试的通信协议帧结构。实测结果表明, 该红外热成像图像处理系统的具有良好的实时性和可靠性。
Abstract
In this paper, the characteristics and technical difficulties of image processing for infrared thermal imager in the vehicle vision enhancement system are discussed, and a vehicle infrared thermal image processing system is designed. Firstly, after the static and dynamic resource consumption of the system evaluated a hardware architecture based on Field Programmable Gate Array(FPGA) and Acorn RISC Machine(ARM) is given. In this architecture, FPGA is used as core processing unit, and ARM is used as control unit. Then, the software design of the image processing system is introduced, and a communication protocol frame structure for system debugging is proposed. Finally, the practical experiments demonstrate the good real-time and reliability performance of proposed system.
