To provide a method and an apparatus for detecting a pedestrian which can detect a movement status of the pedestrian, an electronic device, and a computer-readable medium.SOLUTION: A method includes: acquiring a point cloud frame including point cloud data of a pedestrian; projecting the point cloud data of the pedestrian to a ground coordinate system to obtain projection point data of the pedestrian; determining a direction of a connection line between the two shoulders of the pedestrian, based on a location distribution of the projection point data; extracting a point cloud of a stable region from the point cloud data of the pedestrian based on the direction of the connection line between the two shoulders of the pedestrian, a form change range of the stable region when the pedestrian moves being smaller than form change ranges of other regions of the pedestrian; and determining movement information of the pedestrian based on a coordinate of a center point of the point cloud of the stable region in a plurality of consecutive point cloud frames.SELECTED DRAWING: Figure 2

    【課題】歩行者の運動状態を正確に検出することができる歩行者検出方法及び装置、電子機器及びコンピュータ可読媒体を提供する。【解決手段】歩行者の点群データを含む点群フレームを取得するステップと、歩行者の点群データを地上座標系に投影して、歩行者の投影点データを取得するステップと、投影点データの位置分布に基づいて、歩行者の両肩を結んだラインの方向を確定するステップと、歩行者の両肩を結んだラインの方向に基づいて、歩行者の点群データから、歩行者の移動時の形態変化幅が歩行者の他の領域の形態変化幅よりも小さい安定領域の点群を抽出するステップと、複数の連続する点群フレームにおける安定領域の点群の中心点の座標に基づいて、歩行者の運動情報を確定するステップと、を含む。【選択図】図2
