The invention is suitable for the technical field of computers, and provides an early warning method, device and equipment for abnormal ship driving behaviors, a medium and an early warning system.The method comprises the steps that driver video data corresponding to a target ship are obtained; determining the number of abnormal behaviors of the target driver in unit time according to the driver video data, and comparing the number of abnormal behaviors with a preset number threshold; when the number of the abnormal behaviors exceeds a preset number threshold, obtaining the number of ships within a preset range around the target ship; and reducing the total frame rate of the driver video data according to the number of abnormal behaviors and the number of ships to obtain a sending frame rate, and sending the driver video data to a terminal for early warning according to the sending frame rate. According to the abnormal behavior times of the driver in the unit time and the number of ships in the preset range around the ship, the method reduces the transmission frame rate of the driver video data, reduces the video data volume, improves the transmission efficiency of the driver video data, and improves the early warning response speed.
本发明适用于计算机技术领域,提供一种船舶驾驶异常行为的预警方法、装置、设备、介质及预警系统,方法包括获取目标船舶对应的驾驶员视频数据;根据驾驶员视频数据,确定目标驾驶员在单位时间内的异常行为次数,并将异常行为次数与预设次数阈值进行对比;当异常行为次数超过预设次数阈值,获取目标船舶周围预设范围内的船舶数量;根据异常行为次数和船舶数量降低驾驶员视频数据的总帧率,得到发送帧率,并将驾驶员视频数据按照发送帧率发送到终端进行预警。本方案通过根据驾驶员在单位时间内的异常行为次数和船舶周围预设范围内的船舶数量,降低驾驶员视频数据的发送帧率,减少视频数据量,提高驾驶员视频数据传输效率,进而提高预警响应速度。
