摘要双目立体三维测量是测距的一种重要方式，它是利用成像设备从不同的位置获取被测物体的两幅图像，利用相机成像机理计算图像对应点间的位置偏差，来获取物体三维几何信息的方法。

本文在以往的研究基础上，继续探讨了利用摄像设备从不同角度获取目标物图像，并对图像进行处理以还原目标物体三维位置的方法。实验通过GPS设备精确测量目标三维位置信息，通过使用灯光制造特征点方便图像特征点的提取，并通过合理优化程序检测图像中的特征点信息，并通过数据处理还原特征点的三维信息。82075

Title    three dimensional measurement technology of    the  binocular stereo                                               

Abstract Binocular stereo vision measurement is a kind of important form of 3D measurement, it is based on the principle of parallax and the imaging device to obtain the object to be measured of two images from different locations, through the position deviation of calculated image corresponding points to obtain geometrical information of 3D objects。

In this paper,  it discusses the use of camera equipment from different angles to get the target image on the basis of previous studies, and processes the image  methods to restore the 3D target position。 Through GPS equipment ,the experiment can accurate measure the 3D information of the target, through the use of light manufacturing feature points extraction of image feature points, and by optimizing the program to detect the feature points and through data processing the three-dimensional information of the feature point reduction。

A complete binocular measurement system can be pided into image acquisition, camera calibration, feature extraction, stereo matching, object orientation and so on。 This paper is mainly discussing the two aspects of the camera calibration, target positioning。

Firstly, this paper describes the basic principle of stereo vision distance measurement according to the choice of stereo vision imaging system model。 Secondly, the pretreatment method of image feature extraction is analyzed, and the algorithm is verified by an example。
