摘　　要：碰撞检测分析对于保证地下管线普查成果质量非常重要,以往的管线普查成果为二维形式,碰撞检测也以简单的二维碰撞检测为主。然而,随着地下管线三维可视化应用场景的增加,传统二维碰撞检测方式已不能满足三维空间中复杂的碰撞检测需求。为解决该问题,本文研究对地下管线进行三维碰撞检测的方法,通过实验分析两种三维碰撞检测方法的综合性能以及各自的优缺点,并与传统二维碰撞检测方式进行对比。最后,总结这两种方法应用于三维场景中管线碰撞检测的可行性。The collision detection analysis method is very important for ensuring the quality of underground pipeline survey results.In the past,pipeline survey results were in two-dimensional form,and collision detection was mainly based on simple two-dimensional collision detection.However,with the increase of 3D visualization application scenarios for underground pipelines,traditional 2D collision detection methods can no longer meet the complex collision detection needs in 3D space.To solve this problem,this article studied a method for three-dimensional collision detection of underground pipelines.Through experiments,the comprehensive performance,and advantages and disadvantages of two three-dimensional collision detection methods were analyzed,and compared with traditional two-dimensional collision detection methods.Finally,the feasibility of applying these two methods to pipeline collision detection in 3D scenes was summarized.
