数据处理

The proposed RS decoder is independent of the interval of codeword block. Consequently, it can work not only in a burst mode, but also in a continuous mode.

该结构使译码处理不受数据块间隙长短的约束，既可以处理独立的编码数据块也可以处理连续发送的编码数据块。

Point clouds are discrete data points without the topology relationship between them. So, to facilitate and expedite the extraction of contour points for the late NPR style, firstly we should simplify the point cloud data. In other words, non-contour points should be eliminated but their contour points and feature points should be retained .

点云数据本身是无拓扑关系的离散数据点集，所以，为了方便和加速后期非真实感绘制风格化所需轮廓点的提取，首先对点云数据进行了"粗略"地简化处理，即剔除点云数据中非轮廓点保留了其轮廓点和特征点；然后应用判定准则提取出所表示物体的轮廓点并对其进行"归并"形成便于NPR风格化处理的特征轮廓线；最后再对得到的轮廓线进行NPR风格化效果"加密"处理。

As for the software design, according to the features of angular deflection algorithm, the data processing way is designed as follows: whenever an isochronal packet is acquired, it is processed and the result is accumulated, and the processing of an image is completed when the transmission of the next image is started.

对于系统的软件设计，根据角偏差算法的特点，设计处理数据方式为：每采集一个等时数据包就对该数据包进行处理并将结果累加，到下一幅图像传输开始时完成对上一幅图像的处理。
