To achieve easy and highly accurate draft measurement.SOLUTION: A draft measurement program causes a computer to execute: an acquisition step of acquiring a hull image in which a hull is imaged; an area detection step of detecting a water surface area in the hull image using a detector that receives the hull image as input; a reading step of reading scale values indicated by draft marks in the hull image using a recognizer that receives the hull image as input; and a measurement step of measuring draft of the hull based on the detection result of the water surface area and the reading result of the scale values.SELECTED DRAWING: Figure 3
【課題】容易かつ高精度な喫水計測を実現すること。【解決手段】本願に係る喫水計測プログラムは、コンピュータに、船体が撮影された船体画像を取得する取得手順と、船体画像を入力とする検出器を用いて、船体画像中の水面領域を検出する領域検出手順と、船体画像を入力とする認識器を用いて、船体画像中のドラフトマークが示す目盛数値を読み取る読取手順と、水面領域の検出結果と、目盛数値の読取結果とに基づいて、船体の喫水を計測する計測手順とを実行させる。【選択図】図3
