spatial point meaning in Chinese
空间点
Examples
- Gps is the technology which use the satellite to measure the 3d coordination of spatial points
Gps (全球定位系统)卫星定位技术利用人造地球卫星，确定地面点的空间位置。 - By taking these spatial points as initial guess , all exact real solutions withi n a certain range of variables are found using unrestraint optimization
以这些空间点为初始值，利用无约束优化，得到在一定值范围内的原方程组的全部精确实数解。 - This paper develops 3d graphics with opengl and draws three - dimensional entities visualization by spatial point set . thu three - dimensional effect and visualization of 3d entities figure are strengthened by light
摘要介绍了采用空间点集绘制实体的方法，生成真实感较强的三维实体图形的过程和三维实体的交互式旋转、缩放、多方位剖切等可视化显示。 - Secondly , this thesis purposes a new deformation correction method basing on neural net . it can get the mapping between spatial points and points in the image using this method after getting input , output and condition without considering other factors
最后将图像点的像素坐标输入给训练成功的bp网络,即可得到预期的空间位置,从而建立图像像素点与空间位置的映射关系。 - Now the 2d precision of spatial points is very great , but because by usual correlation fitting method we can transfer gps ellipsoidal height into normal height of the local geoid is considered as mathematical curve plane , it is not conform the fact of mountainous districts so the precision of elevation is so small that it is not satisfied with the requirement of leveling
目前，地面点的平面位置确定精度已相当高，但高程精度始终未能达到水准测量的要求，因为将gps大地高转化为水准正常高的拟合推估方法是将局部大地水准面视为数学曲面，常常与实际情况差异较大(特别在西部山区差异更大) 。
