摘　　要：案例场景的再现对于远程教学具有重要意义,尤其对于某些具有复杂时空场景的典型案例教学,只采用文档、图片、视频等方式展示不够直观形象、体验感差、参与性低。以公安专业课程案例教学为例,通过引入三维全景技术,构建案例现场三维场景平台来模拟案件发生过程,并以交通事故现场勘查为例,在该平台上通过全景展示、多场景切换、调用案件时序热点库等功能进行案例教学实践,使非现场教学更生动化,有效地辅助课堂教学。The reproduction of case scene is of great significance for remote teaching,especially for some typical case-based teaching with complex spatio-temporal scenarios.The presentation of documents,pictures and videos is not intuitive enough,resulting in poor experience and low participation.In order to reproduce the scene of public security cases more vividly in remote teaching,the three-dimensional panoramic technology was introduced and a 3D scene platform for public security case was constructed to simulate the real scene of the case.This paper takes the traffic accident scene investigation as an example to demonstrate the case-based teaching practice carried out on the platform with such functions as panoramic display,multi-scene switching,and case timeline hotspot database calls,so as to make the off-site teaching more lively and assist classroom teaching effectively.
