The invention discloses a traffic accident detection method based on a synthetic video. The method is characterized by comprising the following steps: setting a traffic simulator environment; controlling a vehicle in the simulator to run, and generating a video; repeating the simulation process by adopting different settings to generate a video data set; evaluating the availability of the video set; generating and evaluating a repeated data set, and selecting the data set with the best availability; designing and training a two-stage accident detector; and testing the performance of the detector. Compared with the prior art, the method has the advantages of simplicity, convenience and high detection accuracy, not only realizes simulation of complex real accidents, but also realizes an evaluation method of a synthetic data set, improves the usability, can be better suitable for real traffic videos, has a good use effect, is not easy to be misjudged, and is suitable for popularization and application. The method greatly improves the accuracy of traffic accident detection, and has a certain popularization and application prospect and value.

    本发明公开了一种基于合成视频的交通事故检测方法,其特点是该方法包括:设置交通模拟器环境;控制模拟器中车辆行驶,生成视频;采用不同设置,重复模拟过程,生成视频数据集;评价视频集可用性;重复数据集生成和评价,选取可用性最好的数据集;设计并训练一个两阶段的事故检测器;测试检测器性能等步骤。本发明与现有技术相比具有方法简便、检测准确率高的优点,不但实现对复杂真实事故的模拟,而且还实现了对合成数据集的评价方法,提高了其可用性,能更好适用于真实交通视频,使用效果好,不易被误判为,大大提高了交通事故检测的准确率,具有一定的推广应用前景和价值。
