The present invention relates to a ship identification method in a ship lock monitoring system, which comprises the following steps: 1) acquiring a video taken from the ship lock entrance area, and performing background modeling based on the Vibe algorithm according to the previous f frames of the video, Obtain the background model, and then determine whether there is a moving object in the f+1th frame of the video and subsequent frames; 2) if there is a moving object in the n+1th frame and subsequent frames, then input the frame to In the mobilenet-ssd model of ship entry detection completed in advance, the category information and spatial position information of the ship are recognized; 3) For the spatial information given in step 2), two monitoring points are manually marked on the image in advance 0 and 1, the actual speed of each ship is calculated by recording the time when the ship passes through these two monitoring points in the image. The invention can provide an effective reference for the identification technology of the ship in the control system of the navigable ship lock of the hydroelectric power plant. |
