求翻译：点云模型是实物模型转化为数据模型最原始的表现形式。虽然现在的三维扫描硬件精度高，但在获取点模型数据的过程中，受扫描设备物理特性、扫描环境、光照及人为因素的影响，得到的采样数据不可避免地带有噪声，从而使所获得的测量数据与实体存在一定的偏差。因此在对获取的原始采样数据进行相关数字几何处理之前进行光顺去噪处理成为一个必不可少的步骤。是什么意思？

Point cloud model is a physical model into the data model is the most primitive form of expression. Three-dimensional scanning hardware accuracy, but in the process of access points, the model data by the physical characteristics of the scanning device, scan the environment, light and human factors

point cloud model is a physical model for the data model into the original expressions. Although it is now the 3D Scanning hardware, but in high-precision model data points of access in the process of scanning equipment, physical features, scan the environment, light and the influence of human facto

The cloud model is the working model transforms as the data model most primitive manifestation.Although the present three dimensional scanning hardware precision is high, but in the gain model data process, is scanned%2

Point cloud model is a physical model into a data model the most primitive forms. Although the high precision three dimensional scanning hardware, but gets the point during model data, scanner, scanning of physical characteristics of the environment, light effects and human factors, are inevitably s
