Design And Implementation Of 3D Modeling System Based On Kriging Method

Ore body modeling is an important part of the mining process.The Kriging-based ore body modeling system designed in this paper aims to make full use of the drilling data provided by the exploration process to accurately and quickly model the ore body and improve the efficiency of the geological personnel.This paper analyzes the development status of ore body modeling at home and abroad,introduces Kriging interpolation method and computer related technology,and studies the system demand analysis.Be sure to use the Beego framework as the overall framework of the system,use the Mongo DB database to store data,use Go language to build the background,and combine Java Script and HTML5 to implement the front end.The system is mainly divided into modules for data processing and analysis,generation of ore lines,generation of ore bodies and three-dimensional display.In order to realize the data processing and analysis module,this paper carried out operations such as creating drills,sample length combination,extra high taste processing,and Kriging feasibility analysis for the exploration data.In order to realize the generation of the oreline module,this paper deeply studies the multi-occlusion projection area algorithm,discretizes the block model based on the projected area and the octree idea,and then deeply analyzes the CPU-GPU cooperative acceleration Kriging algorithm.The discrete units are quickly interpolated,then the block segment model is divided into sections.Finally,the section point set is divided by the ore body point set division strategy based on the improved DBSCAN algorithm,and the point set is smoothed by the Cubic BSpline interpolation method.In order to realize the generation of ore body model module,this paper uses the central point connection method to close the coil,and the minimum area method and the minimum circumference method are used to connect the circle line.In this paper,the ore body modeling process is demonstrated in a threedimensional way,and the drilling model,discrete element model,circle line model and ore body model are constructed.The system implements the functions in the demand analysis and achieves the system goals.After trials in actual production,the ore body can be modeled and displayed in three dimensions more accurately and efficiently.
