摘要

设计了一种基于步进电机控制的热成像自动对焦系统,用于漏气定位。采用DFF (Depth From Focus)技术实现热成像的自动对焦。首先设计一个聚焦目标,然后利用能量梯度函数作为边缘检测的评价函数对其热图像的水平温度分布进行运算,最后利用爬坡法获得最优聚焦位置。理论分析和实验结果表明,所采用的控制方案和评价函数能够获得很好的调焦效果,有效克服了被测物体位置差造成的图像虚性。

Thermography autofocus applied in air leak location
A thermography autofocus system based on stepping motor control is designed for air leak location. DFF (Depth From Focus) is adopted to realize the autofocus of thermography. Firstly, a focusing target is designed, and then the horizontal temperature distribution of its thermal image is operated by using energy gradient function as the evaluation function of edge detection, finally the hill climbing method is used to achieve the optimal focusing position. The theoretical analysis and experimental results show that the adopted control scheme and evaluation function can obtain a very good focusing effect and effectively overcome the virtuality of images caused by the position difference of the tested object.
