The invention relates to the technical field of water level monitoring, in particular to an accurate flow velocity measurement method and system based on an unmanned ship. Comprising the following steps: S1, lowering an unmanned ship to a to-be-measured river channel, and selecting and setting a zeroing direction of a measurement section of the to-be-measured river channel; s2, preliminarily measuring the flow velocity of the to-be-measured river channel by the unmanned ship to obtain a preliminary flow velocity; if the initial flow velocity is greater than the set flow velocity, the unmanned ship selects a drifting method to measure the flow velocity; and if the initial flow velocity is not greater than the set flow velocity, the unmanned ship selects a single-point positioning method to measure the flow velocity. The corresponding measurement mode is selected according to the flow velocity condition of the river channel, the flow velocity of the river channel can be accurately measured according to the flow velocity condition, the whole measurement mode is stable and efficient, and great popularization value is achieved.

    本发明涉及水位监测技术领域,具体地指一种基于无人船的流速精准测量方法及系统。包括以下步骤:S1、无人船下放到待测河道,选择并设置待测河道测量断面的归零方位;S2、无人船对待测河道的流速进行初步测量,获得初步流速;若初步流速大于设定流速,无人船选择漂流法对流速进行测量;若初步流速不大于设定流速,无人船选择单点定位法对流速进行测量。本申请根据河道流速情况选择相应的测量方式,能够根据流速情况对河道流速进行精确测量,整个测量方式稳定、高效,具有极大的推广价值。
