To provide an object detection apparatus, a ship equipped with the objection detection apparatus, and an object detection method that improve a detection accuracy of an object without increasing a calculation time period in learning.SOLUTION: An objection detection apparatus detects an object using a first learning model generated by using a plurality of pieces of first teacher data representing an image of the object. The object detection apparatus includes a horizontal detection unit, a correction unit, and an object detection unit. The horizontal detection unit performs detection processing of a horizon included in an image represented by detection image data used for detection of an object. The correction unit corrects the detection image data such that a first angle between a horizontal direction in the image and the horizon is equal to or less than a predetermined angle. The object detection unit performs detection processing of the object using the first learning model in an image represented by the detection image data corrected by the correction unit.SELECTED DRAWING: Figure 4

    【課題】学習時における計算時間を増加させずに、物体の検出精度を向上させる物体検出装置、当該物体検出装置を備えた船舶、および物体検出方法を提供する。【解決手段】物体検出装置は、物体を含む画像を表す第1教師データを複数用いて生成された第1学習モデルを用いて、当該物体を検出する。物体検出装置は、水平線検出部と補正部と物体検出部とを備える。水平線検出部は、物体の検出に用いるための検出用画像データによって表される画像に含まれる水平線の検出処理を行う。補正部は、画像における水平方向と当該水平線との間の第1角度が所定角度以下になるよう、当該検出用画像データを補正する。物体検出部は、補正部による補正後の検出用画像データによって表される画像において、第1学習モデルを用いて物体の検出処理を行う。【選択図】図4
