摄像机

You can think of the projection matrix as defining the properties of the lens of your camera.

你可以认为投影矩阵定义了你的摄像机的镜头属性。

Then we chose a specific position,the extrinsic parameters and the projection matrix attached to the position were obtained.

在已知摄像头内参数的情况下，计算特定位置的平面模板的外参数，从而确定在这一特定位置摄像机的投影矩阵，确定此时图像坐标系与世界坐标系的对应关系。

Based on the model of linearcamera in the stereovision and the character of wandering in the virtual scene, this method can get a projection matrix by thecorrespondence of four points between image space and texture plane.

该方法以立体视觉中的线性摄像机模型为基础，针对虚拟场景漫游的特点及需要，利用透视投影中点的对应关系，通过图像空间与纹理平面上的四点对应，求得纹理校正的投影矩阵。

The code below sets the Camera object's projection matrix once outside the rendering loop.

以下代码将用在渲染循环之外来设定摄像机对象的投影矩阵。

This thesis concentrates on two research fields, one is the technique of camera calibration, the other is the technique of scene rendering based on photographs, according to the projective geometry framework in Computer Vision.

本论文在计算机视觉的几何理论框架下，对摄像机标定技术和基于真实场景图像的绘制技术及应用这两个方面，作了比较深入的研究。

When rotational axis are unknown, the general solution of camera intrinsic parameters is obtained by the eigenvectors of 2D projective transformation.

在摄像机绕未知轴旋转时，根据相应的2D投影变换，运用矩阵特征向量理论给出了内参数的通解公式。

A parametric study graphic nature of the projection, that is, they read the projective transformation, remained the same graphic nature of the geometry, the branches. 2D projective transformation is a more common transform method, used in the camera lens of the camera plane, and applied to various fields of study.

射影几何是研究图形的射影性质，即它们经过射影变换后，依然保持不变的图形性质的几何学分支学科。2D射影变换是一种较为常见的变换方法，发生在用透视摄像机对平面摄像的时候，并应用于各个研究领域。

In order to improve the control performance, when the image distortion is too large resulting from camera obliquity, these parameters are transformed from image coordinate to robot coordinate through projective transformation, while parameters such as position and curvature are not necessarily provided.

为改善控制性能，当由于摄像机倾角较大而引起的图像畸变较大时，利用射影变换把参考轨线参数从图像坐标系映射到机器人坐标系，而无须提供位置、曲率等参数。

Punched tape, punch tapeEach of the two cameras serially records 60 pictures per second. When the tape has been completed, the recorded three-dimensional images can be reproduced on a TV screen using a standard VCR.

每台摄像机以每秒60幅的速率连续拍摄，录像带录满之后，录制的立体图像就可以用标准的盒式放像机在电视机屏幕上进行播放。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
