Abstract: In order to solve the mine early warning information expression is not completely, data statistics analysis based on the vision to work hard, warning data set problems such as confused，a color gradual interpolation 3 d visualization algorithm for mine early warning data sets were proposed.In this algorithm，fist of all，the 3 d space model were constructed according to point position and measured value information of mine early warning data sets,then, mine early warning data sets and color space model was color mapping and were hierarchically divided for three dimensional space according to gray level and color space mapping relationship of the system, each layer were coded for 3 d visualization of false image based on mine early warning data sets according to the false image coding algorithm and color clustering parameters characteristics, the last, smooth transition of adjacent layer by processingfor the false image according to colour gradual interpolation algorithm. The experimental results show that the method of mine monitoring data processing false image color rendering sense of strong, colour smooth transition, can satisfy the mine early warning data sets information expression.

摘要： 针对矿井预警数据信息表达不完全、基于视觉的统计分析工作繁重、预警数据集庞杂等问题，提出了一种基于色彩渐进插值的矿井预警数据集三维可视化算法。在该算法中，首先根据矿井预警数据集的测点位置和测量值信息进行三维空间模型构造;然后根据灰度级与彩色空间系统的映射关系对矿井预警数据集与彩色空间模型进行颜色映射及三维空间层次分割，对每个层片依据伪图像编码算法及颜色聚类参数特征进行矿井预警数据集的三维可视化伪图像编码;最后根据色彩渐进插值算法对伪图像中相邻层片进行平滑过渡处理。实验证明，该算法处理的矿井预警数据集伪图像色彩渲染层次感强，色彩过渡平滑，有利于矿井预警数据集的信息表达。
