The invention provides an automatic monitoring and early warning method for ships in a bridge area water area. The method comprises the following steps: acquiring ship image data in the bridge area water area and acquiring ship contour data and ship position data; acquiring the preprocessed AIS ship position data to obtain target ship position parameter data; performing camera assumed world coordinate system conversion, and matching the ship position data converted to the camera assumed world coordinate system with the target ship position parameter data; dynamic and static information of each ship is obtained, a three-dimensional safety distance model of a bridge area and a water area is constructed, a longitudinal safety distance and a transverse safety distance are calculated, and when the ship has an over-height condition and a ship-bridge collision dangerous behavior, the dangerous ship is highlighted and early warning information is output. According to the invention, the ship image data and the AIS data are fused and displayed, accurate monitoring of ship parameters is realized, and when the ship has an over-height condition and a collision risk, early warning information is output, so that the safety of a bridge water area is improved.

    本发明提供了一种桥区水域船舶的自动监测预警方法,该方法包括:采集桥区水域的船舶图像数据并获取船舶轮廓数据和船舶位置数据;获取经过预处理的AIS船位数据,得到目标船位参数数据;进行相机假定世界坐标系转换,对转换至相机假定世界坐标系的船舶位置数据和目标船位参数数据进行匹配;获取每条船舶动静态信息,构建桥区水域三维安全距离模型,计算纵向安全距离和横向安全距离,当船舶存在超高情况和船桥碰撞危险行为时,突出显示危险船舶并输出预警信息。本发明通过将船舶图像数据和AIS数据进行融合并显示,实现对船舶参数的精准监测,当船舶存在超高情况和碰撞危险时,输出预警信息,提升了桥水区域的安全性。
