| 摘 要： | 自动调焦系统是保证测量电视获得被测目标清晰图像的一个关键部分,快速有效地实现自动调焦,有助于提高整个系统的性能。本论文提出了一种基于图像处理技术的自动调焦方法,采用Sobel边缘检测算子来检测图像的边缘点数,并根据该值判断是否聚焦,同时采用自适应搜索步长的登山算法控制调焦镜头组得到清晰图像。实验证明,使用本论文算法可对复杂条件下的目标实现自动调焦,增强了测量电视的适用性。

| Abstract: | Automatic focusing system is a key part of measuring TV for capturing the clear objective image.It is help to enhance the performance of measuring TV with focusing effectively and quickly.An image type automatic focusing system is proposed.The sum of edge points of an image is used as the criterion function whether the image is focused.The hill-climbing automatic focusing principle with adaptive searching step size is also given.The experiments proved that the system can focus the object in the complex condition and improve the adaptability of measuring TV. |

| Keywords: | automatic focusing sum of edge points adaptive searching step size |
