The embodiment of the invention provides a traffic accident information acquisition method and system and a camera. The method comprises steps: when the camera detects a traffic accident, acquiring afirst relative position of an accident point where a traffic accident occurs in the acquired video, based on the first relative position, obtaining the physical position of the accident point in a world coordinate system through conversion; according the physical position of the accident point, based on a preset time interval, acquiring first traffic flow information of each lane in a preset arearange of the accident point, acquiring a video, and sending the physical position of the accident point, the first traffic flow information acquired at each preset time interval and the acquired videoto a platform server, and the platform server acquires second traffic flow information of each lane of upstream and downstream intersections of the accident point according to the physical position of the accident point and the preset time interval, and associates and records the physical position of the accident point, the first traffic flow information, the second traffic flow information and the video acquired at each preset time interval. According to the scheme, the traffic accident information can be collected in real time.
本发明实施例提供了一种交通事故信息采集方法、系统及摄像机,摄像机在检测到交通事故时,获取采集的视频中发生交通事故的事故点的第一相对位置,根据第一相对位置,换算出事故点在世界坐标系下的物理位置,根据事故点的物理位置,按照预设时间间隔,获取事故点的预设区域范围内各车道的第一车流信息,并采集视频,发送事故点的物理位置、各预设时间间隔获取的第一车流信息及采集的视频至平台服务器,平台服务器根据事故点的物理位置,按照预设时间间隔,获取事故点的上下游路口各车道的第二车流信息,将事故点的物理位置、各预设时间间隔获取的第一车流信息、第二车流信息和视频进行关联记录。通过本方案,可以实现对交通事故信息的实时采集。
