查询词典 perspective projection

In this paper, a series of lunar map projection formulas are deduced including azimuthal projections, cylindrical projections and conical projections. The lunar map projections software is compiled. By caculating lunar map projection distortions, their projection distortion rules are found. Base on the lunar exploration mission, the lunar map projection scheme is given in this paper. The azimuthal conformal projection or the circumcenter perspective azimuthal projection is usually used in small areas, especially in two poles. When the whole map of the moon is needed, the azimuthal conformal projection or the circumcenter perspective azimuthal projection is used within 10° in the poles, and the traverse tangent cylindrical conformal projection or the normal secant conical conformal projection can be used in else areas, furthermore, band-division is necessary to reduce the projection distortion.

本文推导了基于月球参考球的各种投影公式，主要包括方位投影、圆柱投影和圆锥投影；编制了月球地图投影计算软件；对多种月球的投影变形进行了详细的计算，总结分析了各种月球投影的变形规律；结合月球探测的需要，给出了月球投影方案的建议：对于局部的面积较小的投影区域，建议使用等角方位投影或外心透视方位投影；如果绘制月面全图，在两极10°范围内采用等角方位投影或外心透视方位投影，其余区域可以采用等角横切圆柱投影和等角正割圆锥投影，并且要进行分带处理。

Finally, the run-length of data points are extracted by horizontal projection, and the modules corresponding to the run-length are taken to decode.

From the concept, it does the exact opposite of a camera: instead of recording an image of the environment by means of an orthographic or perspective projection, projective texture mapping projects an image onto the environment, by using a matrix very similar to the one a camera uses.

从这个概念上，它与摄象机正好相反，不是通过正交或者透视投影来记录环境的图象，而是把图象投射到环境上，通过使用类似于摄象机使用的矩阵。

This paper puts forward a method of texture rectification based on perspective projection.
