Beschreibung
Zusammenfassung:	A ground detection method, comprising: determining the angle between a scan line and a target ground plane according to the coordinates of a bottom center point and the height of a three-dimensional scanner from the target ground plane (S120); according to the angle and the distance between the three-dimensional scanner and a reference ground plane, determining the length of a scan line segment irradiated by the three-dimensional scanner to an edge point of a recessed area (S130); and determining the width of the recessed area according to the length of the scan line segment and the maximum distance between two bottom points (S140). Further provided are a ground detection apparatus, a device, and a computer-readable storage medium. Procédé de détection de sol, consistant à : déterminer l'angle entre une ligne de balayage et un plan de sol cible en fonction des coordonnées d'un point central de fond et de la hauteur d'un scanner tridimensionnel par rapport au plan de sol cible (S120) ; en fonction de l'angle e
