Utilization o Flexible System for Stereoscopic Measurement by Use of SSD cameras

现在，ccd相机很流行，我们几乎可以使用许多类型的相机。从CCD摄像机的特性可以看出，利用它们构成的立体测量系统具有广泛的应用前景。一个测量系统应该根据我们想要实现的目的而具有特殊的功能。本研究从测量精度、会聚照片立体观察方法、立体匹配及应用范围的扩展等几个方面探讨了立体测量在实际应用中所必须考虑的因素，实现了用CCD摄像机进行在线立体测量、高速传输与显示以及人眼观察。数字立体匹配技术有所改进，但仍不完善。因此，自动立体测量只能在有限的情况下进行，为了用人眼观察数字图像，我们通常使用图像显示器。In有一个根本的优势。一般来说，该显示器价格低廉，操作方便，并且还具有各种有用的功能。从这项研究中可以明显看出以下几点。通过使用图像显示来执行准确的流观观察。可以观察和测量非常强的会聚照片。在各种条件下都能准确、轻松地生成校正后的图像。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。它在工程测量领域得到了广泛的应用。

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.
