摘　　要：针对现有方法自动生成航线时未考虑航道宽度这一问题,提出了一种顾及航道宽度的最短距离航线自动生成方法。所提方法利用风、流致漂移量和航道的安全富裕宽度,构建航道宽度解算模型,并采用一种等价处理方法生成等宽航道,实现了顾及航道宽度的最短距离航线自动生成。实验结果表明:在岛礁区等复杂海域,所提方法能生成顾及舰船航行所需宽度的最短距离航线。Aimed at the shortcoming of building shortest distance route with existing methods without considering channel width,a method for automatically generating the shortest distance route considering channel width is proposed. Firstly,the distance of drift caused by the wind current and safe width of the channel are used to calculate channel width. Secondly,the channel with uniform width is built with equivalent processing method.Finally,the shortest distance route is automatically created considering the channel width. Experimental results demonstrate that the proposed method can create the shortest distance route considering width for navigation.
