一种用变焦镜测距的新方法

本文提出了一种使用变焦镜测量距离的新方法。用一种特别设计的非线性振动的变焦镜首先把三维物空间离散成一系列的球面层，然后把这些离散的球面层图像记录在视频摄像机上。本文引入了一种用于滤除图像中模糊成份的去模糊算法。通过控制变焦镜驱动波的振幅和直流成份，可获得不同的深度范围。调整变焦镜振动的周期，能得到不同深度的精确度。而且通过增加视频摄像机的帧频，有可能把这种测距技术用作一种实时测距的方法。

A New Range Finding Method With A Varifocal Mirror

A new range finding method is proposed in this paper which make use of a varifocal mirror. The three-dimensional object space is first discretized into a sequence of spherical shells with a specially designed uulinear vibrating varifocal mirror, and then these discrete spherical shell images are recorded on to a video camera. A deblurring algorithm is introduced in this paper which is used to remove the blurred components in the images.Through controlling the vibration amplitude and direct current component of the driving wave for the varifocal mirror, we can obtain the different depth range. By adjusting the vibration period of the varifocal mirror, we can get a different depth acuracy and through increasing the frame frequency of the video camera, we may use this range finding technique as a real time range finding method.
