The invention relates to a visual analysis method for a coastal commercial fishing boat collision high-risk area, and the method comprises the following steps: obtaining AIS data, and carrying out the preprocessing of the AIS data; performing operation state identification on the fishing boat to obtain the boat length and the boat width of the fishing boat; encounter data in the preprocessed AIS data are extracted; establishing ship domain models of the current ship and the target ship, and judging whether an encounter situation is formed between the two ships or not; when the meeting situation is formed, the meeting situation between the two ships is obtained; according to the ship domain models of the two ships, whether the ship domains of the two ships intersect or not is judged, and if yes, the collision risk degree between the two ships is obtained; and according to the collision risk degree, judging the collision risk in the whole meeting process of the ship meeting, and performing visual operation on meeting data.
本发明涉及一种沿海商渔船碰撞高风险区可视化分析方法,所述方法包括如下步骤:获取AIS数据,对AIS数据进行预处理;对渔船进行作业状态识别,获取渔船的船长和船宽;提取预处理后AIS数据中的会遇数据;建立当前船舶和目标船舶的船舶领域模型,判断两个船舶之间是否会形成会遇局面;当形成会遇局面时,获取两个船舶之间的会遇态势;根据两个船舶的船舶领域模型判断两个船舶的船舶领域是否有交集,有交集则获取两船之间的碰撞风险度;根据碰撞风险度评判船舶会遇整个会遇过程的碰撞危险大小,并对会遇数据进行可视化操作。
