A Ship Trajectory Prediction Method Based on 2D Convolution and Transformer
论文提出了一种基于二维卷积神经网络与Transformer融合的船舶轨迹预测模型(2D-CNN-Transformer),旨在解决传统方法因离散化位置编码和单一模态特征提取导致的预测精度受限问题.通过连续位置编码技术,模型避免了经纬度网格划分引入的输入误差;结合轨迹图像重建与ResNet空间特征提取,增强了船舶运动轨迹的空间连续性表征;采用交叉注意力机制实现时空特征的动态融合.测试结果表明,在5 min、10 min和15 min预测尺度上,模型轨迹预测的均方误差和均方根误差均优于基线模型.连续位置编码、二维卷积分支和交叉注意力的联合应用,为智能航运系统中的高精度轨迹预测提供了新范式.
This paper proposes a 2D-CNN-Transformer model for ship trajectory prediction,integrating 2D convolution neu-ral networks with Transformer architecture to address the limitations of discrete position encoding and single modal feature extraction in conventional methods.The model employs continuous position encoding to eliminate quantization errors induced by grid-based co-ordinate mapping,reconstructs trajectory images for spatial feature extraction via ResNet,and leverages cross-attention for dynam-ic multi-modal feature fusion.Experimental results demonstrate superior performance in mean square error(MSE)and root mean square error(RMSE)across 5 min,10 min,and 15 min prediction horizons compared to baseline models.The synergistic integra-tion of continuous position encoding,two-dimensional convolutional branches,and cross-attention mechanisms offers a novel para-digm for high-precision trajectory prediction within intelligent shipping systems.
