摘　　要：为避免红外视频在压缩存储过程中发生细节损失,提出了一种红外视频无损压缩的实现方案。该方案采用FPGA作为核心控制,以ADV212为压缩芯片并对其进行分析,选择合适的工作模式进行无损压缩。通过在线切换配置,还可对所存储视频进行解压缩和回放。该方案已经在自主研发的手持式红外观测仪中使用,效果良好。To avoid the loss of details of infrared video data during compression, a method for lossless compression of infrared video data is proposed. The method uses a FPGA as its core controller and uses an ADV212 chip as a compression chip. It can choose the appropriate operation mode for lossless compression. By switching its configuration on line, the saved infrared video data can be decompressed and played back. This method has been used in the portable infrared cameras we developed and good results are obtained.
