The invention relates to an inland ship navigation risk early warning method and device, and the method comprises the steps: carrying out the quantification of ship navigation risk factors, and constructing a three-dimensional dynamic ship domain model; acquiring radar feature information, AIS feature information, river channel water depth information and navigation environment influence information of the ship; performing track prediction based on the AIS feature information and a preset BP neural network model, and performing track fitting with the radar feature data to obtain a predicted track; generating a current ship domain and a predicted ship domain according to the three-dimensional dynamic ship domain model, the predicted track and the channel environment influence information; and judging whether the current ship field and the predicted ship field have the risk of being invaded or not, generating risk early warning information when the risk of being invaded exists, and performing risk early warning prompt to a user. According to the method, the three-dimensional dynamic ship domain model based on multi-factor quantification under spatial-temporal variation is combined with the predicted track, so that the accuracy, rapidity and universality of risk early warning of inland ship navigation are improved.

    本发明涉及一种内河船舶航行风险预警方法及装置,其方法包括对船舶航行风险因素进行量化,构建三维动态船舶领域模型;获取本船的雷达特征信息、AIS特征信息、河道水深信息以及航行环境影响信息;基于AIS特征信息和预设的BP神经网络模型进行航迹预测,并与雷达特征数据进行航迹拟合,得到预测航迹;根据三维动态船舶领域模型、预测航迹和航道环境影响信息生成当前船舶领域和预测船舶领域;判断当前船舶领域和预测船舶领域是否存在被入侵的风险,存在被入侵的风险时生成风险预警信息,向用户进行风险预警提示。本发明将时空变化下基于多因素量化的三维动态船舶领域模型和预测航迹相结合,提高了内河船舶航行风险预警的准确性、快速性与普适性。
