Abstract

The present application provides a method for monitoring a flow velocity and a flow direction of a tidal flat coastal current based on photovoltaic video images of a tidal flat. The method includes: obtaining a tidal flat video of a target area to be monitored; performing scene recognition based on the tidal flat video to obtain tidal flat seawater images; determining a number of observation lines based on the tidal flat seawater images, and setting a plurality of parallel flow velocity observation lines in a north-south direction and an east-west direction according to the number of the observation lines, respectively, where the parallel flow velocity observation lines include north-south parallel flow velocity observation lines and east-west parallel flow velocity observation lines; making the north-south parallel flow velocity observation lines intersect with the east-west parallel flow velocity observation lines to obtain flow velocity nodes; and obtaining the flow velocity and the flow direction of the tidal flat coastal current based on a north-south component and an east-west component of the flow velocity nodes. According to the present application, planar monitoring can be implemented, and interference of irrelevant areas can be avoided. Details of areas having local turbulence or significant changes can be effectively recorded. Flow velocity characteristics of different positions in a large-scale monitoring area can be fully reflected.
