The invention provides an active anti-ship-collision early warning method and system for a bridge. The method comprises the following steps: acquiring image information and a motion characteristic signal of a target ship body; pre-processing the image information by adopting a self-adaptive threshold filtering method to obtain a pre-processed image; inputting the preprocessed image into a trained hull recognition model to obtain a recognition result; the identification result comprises contour point coordinates of the target ship body; performing wavelet denoising on the motion characteristic signal to obtain a denoised signal; according to the de-noised signal and the identification result, simulating a motion track of the target ship body at a future moment; and performing collision judgment according to the motion trail and preset bridge information, and if a judgment result is collision, performing early warning. According to the invention, the relative position and motion state of the target ship body can be monitored in real time, and when possible collision is detected, an early warning signal can be sent out in time to guide the ship to take avoidance measures, so that the bridge safety is improved.

    本发明提供了一种桥梁主动防船撞预警方法及系统,方法包括:获取目标船体的图像信息和运动特征信号;采用自适应阈值滤波方法对所述图像信息进行预处理,得到预处理图像;将所述预处理图像输入至训练好的船体识别模型中,得到识别结果;所述识别结果包括目标船体的轮廓点坐标;对所述运动特征信号进行小波去噪,得到去噪信号;根据所述去噪信号和所述识别结果模拟未来时刻的所述目标船体的运动轨迹;根据所述运动轨迹与预设桥梁信息进行碰撞判断,若判断结果为碰撞,则进行预警。本发明能够实时监控目标船体的相对位置和运动状态,当检测到可能发生撞击时,能够及时发出预警信号,指导船舶采取避让措施,从而提高桥梁安全性。
