Concerning the incomplete expression of the mine pre-warning information, big work load of data statistics analysis based on the vision, and complicated pre-warning data set, a 3D visualization algorithm of color gradual interpolation for mine pre-warning data sets was proposed. In this algorithm, first of all, the 3D space model was constructed according to point position and measured value information of mine pre-waming data sets, then, mine pre-waming data sets were mapped to color space model and hierarchical divided to three dimensional space according to gray level and color space mapping relationship of the system, each layer was coded for 3D visualization of false image based on mine pre-waming data sets according to the false image coding algorithm and color clustering parameter characteristics. At last, smooth transition of adjacent layer in the false image was carried out according to colour gradual interpolation algorithm. The experimental results show that the false image got by the proposed method has strong color rendering layer and smooth transition in colour and can satisfy the mine pre-waming data sets information expression.%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.
