红外成像区域法自动调焦聚焦区域的研究

Study of the focus area in the automatic focusing system of infrared imaging zone method

在红外成像区域法自动调焦系统中,聚焦区域选择很重要。为此,对一组红外图像进行实验仿真,选择相同大小、不同位置的聚焦区域观察其对调焦评价函数曲线的影响,以及选择同一聚焦位置、不同大小的聚焦区域观察其对调焦评价函数曲线的影响,通过分析得出聚焦区域选择的基本原则。

In the automatic focusing system of infrared imaging zone method, the selection of focus area is very important. To choose the position of focus area and the focus size of image, this paper did experimental simulation with a group of infrared image, to observe that focus area influence on the curves of focusing appraisal function selecting the same size different positions and the same position different sizes of the focus area, and getting the basic principles of the focus area selection through the analysis.
