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

CCD相机现在很流行，我们实际上可以使用许多类型的CCD相机。从CCD相机的特性可以看出，利用CCD相机构建的立体测量系统具有广泛而多样的用途。一种测量系统应根据所要达到的目的，具有一定的特点。本文从测量精度、会聚影像立体观测方法、立体匹配、扩展应用领域等方面探讨了实际应用的必要因素。在线立体测量将通过CCD相机、高速传输和显示以及人眼观察来实现。数字立体匹配技术得到了改进，但仍然不完善。因此，自动立体测量只能在有限的情况下进行。为了用肉眼观察数字图像，我们通常使用图像显示器。它有一个根本的优势。显示器价格低廉，操作方便，而且还具有各种有用的功能，一般来说。从这项研究中可以明显看出以下几点。利用图像显示器进行精确的立体观测。非常强的收敛照片可以观察和测量。在各种条件下都能准确、方便地产生校正图像。该系统操作简单。这样，想要获得一些测量数据的工程师可以方便地自行使用该系统。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.
