摘要
随着红外技术的发展,红外传感器在各领域内广泛应用,常用于监控、安检、目标跟踪等。在一些特殊场合,如无人机获取目标信息,都需要记录整个过程,以备后续进行分析处理,与其他样本进行综合比较,从而获取更多信息。针对上述需求,进行了基于FPGA+DSP架构的红外图像存储与回放系统的设计,同时对存储芯片进行坏块管理,保证存储的可靠性,图像数据通过千兆以太网发送到上位机,完成数据卸载与回放。
With the development of infrared technology, infrared sensors are widely used in various fields such as monitoring, security checking and target tracking. In some special occasions, for example unmanned aerial vehi- cle （UAV） acquiring target information, the whole process is needed to be record to prepare for the subsequent analy- sis, treatment and comparison with other samples, so as to get more information. According to above requirements, the infrared image storage and a playback system based on FPGA＋DSP architecture are designed. And bad block management for memory chip is performed to ensure the reliability of the memory. Image data is sent to the host computer through Gigabit Ethernet to complete data offload and playback
