The invention relates to the technical field of ship draft calculation, and provides a ship draft calculation method which is used for calculating the draft of an inland river bulk cargo ship by using side-scan sonar. Comprising the following steps that S1, a side-scan sonar is installed at the bottom of one side of a navigation channel, and the side-scan sonar continuously emits sound beams to the water surface for 24 hours; s2, when the side-scan sonar receives a strong echo signal generated by a ship body on the sound wave beam, judging that a ship target appears; and S3, according to the sonar data received by the side-scan sonar, finding the strong reflection signal of the intersection point of the ship body and the water surface and the sampling point position of the strong reflection signal of the bilge, and calculating the draft value of the ship body by combining the installation depth of the side-scan sonar.

    本发明涉及船舶吃水深度计算技术领域,提供了一种船舶吃水深度计算方法,用于利用侧扫声呐实现对内河散货船的吃水深度进行计算。包括以下步骤:S1:在航道一侧的底部安装侧扫声呐,所述侧扫声呐24小时不间断向水面发射声波束;S2:当所述侧扫声呐接收到船体对所述声波束产生的强回波信号时,判断船舶目标出现;S3:依据所述侧扫声呐接收到的所述声呐数据,找到所述船体与水面交点的所述强反射信号和船舭部所述强反射信号的采样点位置,结合所述侧扫声呐的安装深度计算出所述船体的吃水深度值。
