Abstract
A method and a device for detecting an object stacking state, and an intelligent shelf are disclosed. The method comprises capturing a color image and a depth image that are aligned with each other above a reference plane in which the object is located, identifying the object and an area occupied by the object in the color image, converting the depth image into a height map relative to the reference plane, determining a reference height of the object based on the height map and the area occupied by the object, acquiring an actual height of the object based on the identified object, and comparing the reference height of the object with the actual height of the object and judging a stacking state of the object based on a result of the comparing.
