    The invention relates to a ship collision risk analysis method, which comprises the following steps of: according to AIS dynamic data of ships of known types, constructing a neural network prediction model capable of judging ship types according to the AIS dynamic data; performing grid division on the target sea area; traversing all grids in the target sea area, and calculating collision elements of different types of ships in each grid according to the neural network prediction model; performing weighted linear superposition on the collision elements in each grid to obtain collision risk quantized values of different types of ships in each grid; and superposing the collision risk quantized values of the different types of ships in each grid within a preset time, dividing the collision risks of the different types of ships in each grid into a plurality of grades according to an equidistant division method, and carrying out risk grade visualization in a thermodynamic diagram form in a map. The ship collision risk level in the target sea area can be analyzed according to the AIS ship position data.

    本发明涉及一种船舶碰撞风险分析方法，包括以下步骤：根据已知类型船舶的AIS动态数据，构建能够根据AIS动态数据判断船舶类型的神经网络预测模型；对目标海域进行网格划分；遍历所述目标海域中的所有网格，根据所述神经网络预测模型，分别计算出各个网格中不同类型船舶的碰撞要素；将各个网格内的碰撞要素做加权线性叠加，得到各个网格的不同类型船舶的碰撞风险量化值；叠加预设时间内所述各个网格的不同类型船舶的碰撞风险量化值，按照等距离划分法将各个网格内的不同类型船舶的碰撞风险划分为若干等级，并在地图中以热力图的形式进行风险等级可视化。本发明能够根据AIS船位数据分析出目标海域内的船舶碰撞风险等级。
