The invention relates to a ship draft depth measuring method and system.The method comprises the steps that measuring device recognition equipment is arranged on a ship, a measuring device comprises a support with a throwing opening, a calibration plate placing mechanism arranged at the top of the support and image collecting equipment arranged at the bottom of the support, and a calibration plate placed in the calibration plate placing mechanism can be pushed out by the calibration plate placing mechanism; the calibration plate falls off from the throwing opening; the image acquisition device acquires video stream data of the calibration board falling from the putting port and sends the video stream data to the identification device; the identification equipment reads the video stream data, processes the video stream data to obtain a plurality of video frame images after the calibration plate falls on the water surface, calibrates the image acquisition equipment according to the plurality of video frame images to obtain an external parameter matrix from the plurality of image acquisition equipment to the calibration plate, and identifies the calibration plate on the basis of the external parameter matrix from the plurality of image acquisition equipment to the calibration plate. The vertical distance between the calibration plate and the image acquisition equipment is obtained, and the draft of the ship is obtained based on the ship body height and the vertical distance of the ship.

    本发明为一种船舶吃水深度测量方法及系统,其中方法包括:在船舶上设置测量装置识别设备,测量装置包括设有投放口的支架、设在支架顶部的标定板放置机构、设在支架底部的图像采集设备,标定板放置机构可推出其内部放置的标定板,使得标定板从投放口掉落;图像采集设备采集标定板从投放口掉落的视频流数据,发送给识别设备;识别设备读取视频流数据,对视频流数据进行处理,得到标定板落在水面后的多张视频帧图像,根据多张视频帧图像对图像采集设备进行标定,得到多个图像采集设备到标定板的外参矩阵,基于多个图像采集设备到标定板的外参矩阵,得到标定板与图像采集设备之间的垂直距离,基于船舶的船体高度和垂直距离,得到船舶的吃水深度。
