查询词典 perspective projection

The techniques of projection center finding and perspective plane determination in 3 D PIV have been investigated profoundly.

对三维PIV中透视投影的视点定位与透视平面的确定技术作了深入的研究，提出了一种确定视点坐标与透视平面的方法，给出了相应的数学关系式，最后通过实验的方法对视点坐标与透视平面的确定技术进行了检验。

More complicated perspective projections can be composed by combining this one with rotations, scales, translations, and shears to move the image plane and center of projection wherever they are desired.

The accelerated algorithm of volume rendering based on textures mapping and the wavelet-based multiresolution volume rendering in network are performed by using OpenGL 3D visualization technique. From the point of view of computer graphics, 3D visualization mechanism of volume rendering based on OpenGL textures mapping is studied, including modelview transformation, projection transformation, perspective division, viewport transformation and the ways to embed textures mapping and blending in above four transformations.

利用OpenGL三维可视化技术实现了本文所提出的基于纹理映射的体绘制加速算法和网络环境下基于小波的体数据的多分辨率体绘制，并从计算机图形学的角度，研究了基于OpenGL纹理映射技术的体绘制的三维可视化流程，包括OpenGL的模视变换、投影变换、透视除法、视区变换，以及纹理的定义、映射与融合等步骤在上述四个变换中的嵌入方法。

We can then use this set of unwarped perspective images to calculate the relative poses of the calibration plate as well as the projection error of the feature points on the calibration plate by using the homography method.

接下我们就可以用所计算出的这组反扭曲影像，计算出虚拟相机与校正物之间的相对姿势，且再用homography方法我们可以计算出校正版上每个特徵点的校正误差。

The paper analyzes theoretically the influence law of length distortion after the reductions from measured side length to reference ellipsoid surface and then from side length on the reference ellipsoid surface to gauss perspective plane. It also discusses theoretical methods to restrict and the projection distortion influence.

从理论上分析了将实测边长归算到参考椭球面上和将参考椭球面上的边长归算到高斯投影面上的长度变形影响规律，讨论限制和减小这种投影变形影响的理论方法。

In chapter I, this paper elaborates the present historical context of metaphor, presents a contextual analysis of metaphor from the perspective of philosophy of language, points out that syntactics construction is the carrier, semantics projection is the essence and pragmatics choice is the creation mode of metaphor in a certain context.

本文第一章在给出了隐喻研究的当代历史语境之后，从语言哲学的角度考察并说明了：在特定语境中，语形构造是隐喻的载体，语义映射是其本质，语用选择是其生成方式，从而给出了一个较为细致全面的隐喻的语境分析。

You can have two different projections in OpenGL: the perspective or the orthographic projection.

你可以在OpenGL中有两个不同的预测：观点或正投影。

When representing cubic images, there are more people choose the range of 8 x 8pixel (34.1%, 37.8%) for horizontal projection and one-point perspective, and more people choose the range of 12 x 12pixel (35.4%, 48.8%) for two-point perspective and three-point perspective.

在水平投影与一点透视表现立方体的图像中，较多人选择8像素*8像素的范围（34.1%，37.8%）；在两点透视与三点透视表现立方体的图像中，较多人选择12像素*12像素的范围（35.4%，48.8%），显示出在制作立体图像时，在这些像素范围以上的图形能获得较佳的视认绩效。
