基于颜色突变的预警彩色位移云图的绘制算法

Colorful Displacement Nephogram Rendering Algorithm based on Warning of Color Mutations

利用测量数值是连续变化的和颜色参数是离散数值的特点,针对地下工程沉降离散监测点的数据分析要求,通过总结各种云图的生成方法,提出了一种新的绘制彩色云图的方法。该法使用简便,绘制效率高、易于推广。如果观测的数据点的位移沉降大于允许值,如出现塌陷,根据该测点及周围测点的位移变化,定位预警点,具体预警点云图颜色会出现显著变化,与周围区域形成鲜明对比。

In view of underground engineering settlement discrete monitoring data analysis requirements, a new method of color image of nephogram rendering is proposed, in thought of measuring changes in the numerical and color parameters is the dispersional of numerical characteristics, by summing up the various nephogram generation. The method is simple to use, rendering efficient and easy to promote. If data points in observation are greater than the allowed displacement values, such as a collapse, the algorithm will locate the specific warning point, considering the measuring point and the displacement measuring points around changes, warning of the specific point makes cloud color changes will be significant, with the surrounding in sharp contrast to the region.
