The invention relates to the technical field of ship intelligent detection, in particular to a channel ship gate entering safety detection method and device, and the method comprises the layout and installation of a camera and a laser radar, and the steps of the method. The method comprises the steps that a camera shoots a lateral front image, and ship 3D detection tracking is carried out; correcting external parameters of the camera by using the real-time water surface height, and calculating a real position; identity verification is carried out before entering a scanning area, and the laser radar scans the whole ship after the identity verification is qualified; judging that the ship is completely driven away from the scanning area, and carrying out ship height and draught safety verification; and checking the speed of the ship in the near-gate area. According to the method, the camera and the laser radar are combined, the advantages of the camera and the laser radar are taken, three detection links of identity verification, ship height and draft verification and near-gate-area speed verification are achieved, information of the ship to be fed into the gate is actively fed back in real time, the labor cost is reduced, and safety and efficiency are both considered.
本发明涉及船舶智能检测技术领域,特别涉及一种航道船舶进闸安全检测方法及其装置,包括:相机和激光雷达的布局和安装,以及方法步骤。步骤包括:相机拍摄侧前方图像,进行船舶3D检测跟踪;利用实时水面高度进行相机外参修正,计算真实位置;进入扫描区前,进行身份校验,合格后激光雷达进行整船扫描;判断完全驶离扫描区,进行船高及吃水安全校验;近闸门区域船舶速度校验。本发明联合相机和激光雷达,取两者优点,实现了身份校验、船高及吃水深度校验、近闸门区速度校验三个检测环节,主动实时反馈待进闸船舶的信息,降低了人工成本,兼顾了安全性和效率。
