摘要:
相比于传统自动调焦方法,基于图像处理的光电自动调焦技术具有智能化、速度快、准确性高、便于控制等优势,已成为自动调焦技术研究的主流方向。本文首先通过构建模型,详细阐述了基于图像处理的光电自动调焦原理和流程,并简要介绍了两种常用自动调焦方法;接着,基于对焦深度法给出了本文设计的自动调焦方案;最后,利用搭建的原理性样机开展了自动调焦实验,验证了本文方案的可行性。
Compared with the traditional automatic focusing method, the photoelectric automatic focusing technology has become the main research direction due to its advantages, such as high intelligence, speediness, accuracy and convenient control. In this paper, the principle photoelectric automatic focusing based on imaging processing is stated in detail, and two common automatic focusing methods are introduced in brief. Then, this automatic focusing scheme is designed and put forward. At last, the automatic focusing test is carried out, and its feasibility is verified.
