| 摘 要： | 以规则格网来组织数据对坡度滤波方法进行改进,通过比较格网最低点与邻域最低点的坡度得到初始地形,再通过比较格网点与邻域格网最低点的判断获得数据点的地形信息,试验结果表明,对坡度的滤波方法有很大改进,也改善了滤波效果。

| Abstract: | An improved slope filter method based on the rules of grid to organize data is proposed.It can get initial terrain through comparing the grid lows and neighborhood low slope,and get data points terrain information through comparing the point of grid node with neighborhood grid low slope.The results of this experiment prove that the concept of the proposed improved method is promising,and it does significantly improve the filter quality compared to conventional slope filter techniques. |
