热成像过程中的视场选取问题

THE SELECTION OF FOV IN INFRARED THERMAL IMAGING

详细讨论热成像过程中机场选取与跟踪概率、空间分辨率的关系，认为在测量动态目标时，固定视场选取不能保证空间分辨率满足采样定理。通过数学建模和计算机仿真，实现机场选取的自动控制，获得最佳的热留空间分辨率。

The relation of FOV selection with tracking probability and space resolution is discussed in the paper. We think that, in the observing of moving objects, the fixed FOV selection cannot make the space resolution meet the sample law. The automatic selection of FOV and the best space resolution of thermal image are reached by our math modeling and computer simulation.
