The invention provides a traffic accident analysis method and system based on traffic scene three-dimensional reconstruction, and relates to the technical field of accident analysis, and the method comprises the steps: receiving traffic accident basic information, then carrying out preset time zone backtracking, obtaining a traffic accident role video sequence, configuring a traffic scene constraint range, and carrying out static scene reconstruction; the method comprises the following steps: acquiring a static three-dimensional scene, performing dynamic feature extraction to obtain dynamic feature information, and finally performing accident restoration to obtain an accident triggering reconstruction time comment and sending the time comment to a user side. The technical problems that in the prior art, an accident site cannot be accurately restored, behavior analysis of each role is lacked, interference of irrelevant information is caused, and accuracy and efficiency of data analysis and processing are further affected can be solved; accurate reproduction of an accident scene, deep analysis of role behaviors, improvement of accident analysis efficiency, optimization of user interaction experience and enhancement of decision support can be realized.
本申请提供了基于交通场景三维重建的交通事故分析方法及系统,涉及事故分析技术领域,该方法包括:接收交通事故基本信息,然后进行预设时区回溯,获得交通事故角色视频序列,配置交通场景约束范围,进行静态场景重建,获得静态三维场景,然后进行动态特征提取,获得动态特征信息,最后进行事故还原,获得事故触发重构时评并发送用户端。通过本申请可以解决现有技术不能准确地还原事故现场,缺乏对各个角色的行为分析,导致无关信息的干扰,进一步影响数据分析和处理的准确性和高效性的技术问题,可以实现事故现场的精准重现、角色行为的深度分析、事故分析效率的提升、用户交互体验的优化以及决策支持的加强效果。
