透视平面

Among the objects as the principle of geometric perspective and aerial perspective, and make it conveying deep stereo spatial feeling on planar painting.

在绘画中，依照几何透视和空气透视的原理，描绘出物体之间的远近、层次、穿插等关系，使之在平面的绘画上传达出有深度的立体的空间感觉。

The purposed thesis will resolve these problems by using perspective anamorphosis.

为了解决这些问题，本研究将使用透视的Anamorphosis，在平面上产生物件的三维模拟视觉。

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。

Whereas parallel projections are used to project points onto the image plane along parallel lines, the perspective projection projects points onto the image plane along lines that emanate from a single point, called the center of projection.

与平行投影沿着平行线将物体投影到图像平面上不同，透视投影按照从投影中心这一点发出的直线将物体投影到图像平面。

A calibration model was established by introducing a planar target that could move freely with three collinear and known mutual location points. The calibration point coordinates in a camera coordinate system could be calculated by using the imaging information of three points and the light stripes on image plane of the camera.

引入一个可自由移动的平面靶标，靶标上只需要共线且相互位置确定的3个特征点，利用共线三点建立三点透视数学模型，根据3个特征点以及光条纹在摄像机像面的成像信息，获取了光平面上标定点在摄像机坐标系下的坐标。

In order to recognize the 2D shapes, we proposed a set of perspective invariants of a pair of coplanar conics in this paper, we suggest a perspective invariant representation of general planar curve based on ellipse, and give an algorithm using the invariants and the representation to recognize 2D shapes.

为了实现二维形状的透视投影不变性识别，本文推导出了一种共面二次曲线对的透视投影不变量，提出了一种基于椭圆的平面曲线的透视不变性表示方法，并且给出了用该不变量和不变性表示方法实现二维形状识别的算法。

That is because the model is based on the ideal situation to presume the viewpoint as infinitely far away from the target. So it doesn't include the information of projection plane changing.

这是由于传统的模型是基于二维的平面运动模型，假设为投影点无穷远的情况，并不包含三维透视投影平面变化的信息，因此不能处理。

According to a theory of computer vision, the most general transformation that can occur between a scene plane and an image plane under perspective imaging is a plane projective transformation.

根据计算机视觉的理论，在透视变换的情况下，一个景物平面与一个图像平面之间的变换是平面投影变换。

This process is as follows: applying projective transformation on the plane, using interpolation method to acquired texture, and then mapping it on the model.

讨论了如何纠正平面纹理的透视变形，及其相应的纹理映射，其过程是在两视图重建的基础上，对原平面进行投影变换，并用插值方法获得纹理，从而映射到模型上。

人类在长期的艺术实践和探索中，创造和发明了许多表现空间远近的方法，从形体和空间关系来说，有平面透视、倾斜透视；从观察位置与观察对象之间的关系来说，则有散点透视和焦点

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.

他拔下桅杆，把帆卷起，系住。
