球面极 meaning in English

spheric polar

3d points are converted to images based on spherical polar coordinates , and point cloud surface information such as location , normal and color are stored in two - dimensional images
本文通过球面极坐标将点云曲面的几何信息及表面属性信息映射到二维图象中去。
From the point cloud surfaces , multi - layered geometry images are created which can represent the original models accurately very much . the compounded geometry image representation of point cloud surfaces , is also based on the former transform method , where the difference lies : take one of coordinates as the gray value and another two as location respectively , three different geometry images can be created . three gray images are combined into a compounded color image
点云曲面的复合图象表示方法，首先把点云曲面中点的笛卡尔坐转换为球面极坐标，分别把球面极坐标[ r ，， ]中的一个坐标转换为象素的灰度值，另外两个量转换为该象素的坐标，这样就可以得到三幅不同的图象，把这三幅灰度图象分别对应到彩色图象的r ， g ， b中去，就组合成为一幅复合彩色图象。
