基于视频目标检测的桥梁防船撞主动预警技术研究*

为减少船撞桥事故的发生,提高桥区水域的通航安全等级,以目标检测算法为基础通过AForge.NET工具包设计实现对桥区水域的运动船舶实时检测与跟踪。根据运动船舶的航行轨迹预测船舶航向,判断船舶是否具有撞桥危险并做出相应预警措施。并在安徽淮河干流蚌埠段等进行验证试验,试验结果表明检测效果良好,能够对高等级航道桥群河段的桥梁防撞主动预警提供有效可行的实施方案。

Active forewarning technology for anti-collision between ship and bridge based on video object detection

In order to reduce the accidents from collision between ship and bridge, and improve the navigation safety of the bridge area of water, we carry out real-time detection and tracking to the moving ship of the bridge area of water based on the object detection arithmetic and by the AForge.NET toolkit design, forecast the course of a ship according to the navigation contrail of the moving ship, estimate whether the ship is facing the danger of bridge collision, and then take relative forewarning measures. The test in Bengbu of the mainstream of the Huaihe river in Anhui province proves that and the detection effect is satisfactory and can provide availability and feasible proposal to the active forewarning of the bridge anti-collision of the bridge group in the river of advanced channel.
