摘要: 针对目前广泛使用的经验取浅方法在安全可靠性上的不足,提出了一种基于不确定度的水深控浅方法。所提方法计算了原始观测和内插水深的不确定度信息,并基于不确定度信息设计了安全可靠的水深控浅模型,比对分析了两种水深方法的安全可靠性。实验证明:与经验取浅方法相比,所提方法可明显提高水深模型的安全可靠性,特别是在水深变化复杂的区域。

Abstract: Aiming at the shortage of a common experiential shoal-biased method assuring navigation safe, a method for controlling shoal-bias based on uncertainty is proposed. Uncertainties of raw depth and interpolated depths are calculated, a safe and reliable model for controlling shoal-bias with a quantitative value based a depth uncertainty is designed, and the probability of two depth models assuring navigation safe are compared and analyzed. Experimental results demonstrate: The proposed method is much more reliable in security than that of the experiential shoal-biased binning method, especially in areas where depths change complexly.
