高速红外图像判读系统设计研究

Design Research of High-Speed Infrared Image Interpretation System

针对实时跟踪领域事后图像判读处理数据量大、时间冗长的问题,提出了一种新型高速图像判读系统.该系统基于多线程乒乓缓冲技术,实现了图像加栽、显示及处理三项工作相互独立和并行执行.通过对红外图像进行灰度拉伸,预处理,亚像元插值细分等操作,有效提高了判读准确度.实验表明,该判读系统提高了数字图像判读系统的工作效率,大大缩短了数据处理时向.

Aiming at the problem of huge data amount and slow processing speed in the afterwards interpretation field,a new high-speed image interpretation system,isproposed. This system is based on the multithread Ping-Pong buffer technique and implements the parallel execution of image loading, image display and image interpretation. Interpretation precision is improved by manifold gray-mapping preprocessing and sub-pixel techniques. Designing experiments indicate that the system is efficiently improved and effectively solved the problem of long-time data processing progress in high-speed image storage system.
