犯罪现场三维重建与虚拟仿真结合的O2O混合实训教学模式探析

Research on O2O mixed training teaching mode combining 3D reconstruction and virtual simulation of crime scene

"犯罪现场勘查"是公安学的一门主干课程。近年来三维激光扫描技术及虚拟现实技术、人工智能技术的快速发展,智勘采集终端已经可以快速复制现场,为该课程的实训改革提供了良好的技术支撑。文章对犯罪现场三维重建与虚拟仿真结合的O2O混合实训教学模式进行了探讨。结果表明,线下实训可指导学生完成真实犯罪现场的三维重建,在此基础上导入虚拟仿真平台系统,进行沉浸式的线下或线上的现场勘查与分析,利用多种技术手段,结合线上线下两种实训模式,充分发挥网络与传统实训教学方式的优势,互为补充,使该实训课程更为贴近实战需求,学生在实践中更好地培养现场勘查能力与专业技能。

"Crime Scene Investigation"is a main course of public security science. In recent years, with the rapid development of 3 D laser scanning technology, virtual reality technology and artificial intelligence technology, the intelligent exploration and acquisition terminal has been able to quickly copy the scene, which provides a good technical support for the training reform of this course. The offline training can guide students to complete the 3 D reconstruction of real crime scene. Based on this, the virtual simulation platform system is introduced to conduct immersive offline or offline scene survey and analysis. By using multiple technical means and combining online and offline training modes, the advantages of network and traditional training teaching methods can complement each other.This paper discusses the teaching mode of O2 O mixed training combining 3 D reconstruction of crime scene and virtual simulation.
