翻译后摘要：该报告开发了一个参数化模型的计算机控制的可移动摄像头的云台。该模型将对象空间到图像空间的变换表示为相机的控制变量的函数。我们构建了一个校准系统，用于测量模型参数，其具有足够的精度，足以满足我们目前的需要。我们还确定了模型测量误差的主要来源是不希望的图像运动，并开发了测量和补偿其中一些并消除其他部分的方法。如果系统图像失真成为主要的精度限制，该系统可以测量系统图像失真。它已被证明如何推广的模型，以处理小的系统误差，由于方面的云台几何目前没有占。该报告演示了该模型在立体视觉中的应用，并展示了它如何作为预测设备应用于定位感兴趣的对象并将其置于图像中心。（作者）
Abstract : The report developes a parametric model for a computer-controlled moveable camera on a pan-tilt head. The model expresses the transform relating object space to image space as a function of the control variables of the camera. We constructed a calibration system for measuring the model parameters which has a demonstrated accuracy more than adequate for our present needs. We have also identified the major source of error in model measurement to be undesired image motion and have developed means of measuring and compensating for some of it and eliminating other parts of it. The system can measure systematic image distortions if they become the major accuracy limitation. It has been shown how to generalize the model to handle small systematic errors due to aspects of pan-tilt head geometry not presently accounted for. The report demonstrates the model's application in stereo vision and have shown how it can be applied as a predictive device in locating objects of interest and centering them in an image. (Author)
