项目摘要

CCD camera are, now, popular and we can use practically many types of them. From the properties of CCD cameras, we can understand that a stereoscopic measuring system constructed by use of them may be applied in extensive and various purposes. A measuring system should have the special features according to the purposes which we want to accomplish. In this study, necessary factors for practical applications, such as measuring accuracy, method of stereoscopic observation for convergent photographs, stereo matching and extension of application fields, were dealt with.On-line stereoscopic measurement will be realized a CCD camera, a high speed transfer and display of and a human eyes observation. Digital stereo matching techniques were improved, but still incomplete. Therefore, an automatic stereoscopic measurement can be practiced only in limited cases.In order to observe the digital images by human eyes, we usually use image displays. In has a fundamental advantage. The display is inexpensive, easy to operate, and also has various useful functions, in general. The followings are evident from this study. Accurate streoscopic observations are performed by use of image displays. Very strong convergent photographs can be observed and measured. Rectified images are produced accurately and easily under various conditions. The system is easy to operate. Then, an engineer who want to get some measuring data can easily use the system by himself. It causes wide use in the fields of engineering measurements.

CCD照相机现在很流行，我们实际上可以使用许多类型。从CCD摄像机的特性可以看出，利用CCD摄像机构成的立体测量系统具有广泛的应用前景。测量系统应根据我们要实现的目的而具有特殊的功能。本文讨论了实际应用的必要因素，如测量精度、会聚照片的立体观察方法、立体匹配和应用领域的扩展，通过CCD相机实现在线立体测量、高速传输和显示以及人眼观察。数字立体匹配技术得到了改进，但仍不完善。因此，自动立体测量只能在有限的情况下进行，为了使人眼能够观察到数字图像，我们通常使用图像显示器。它有一个基本的优势。一般来说，该显示器价格便宜，易于操作，并且还具有各种有用的功能。从这项研究中可以看出以下几点。通过使用图像显示器进行精确的立体观测。可以观察到和测量到非常强的会聚照片。在各种条件下准确且容易地产生校正图像。该系统操作简单。这样，想要获得一些测量数据的工程师就可以很容易地自己使用该系统。它在工程测量领域有着广泛的应用。
