Abstract

The embodiment of the invention provides a method and a device for measuring the volume of a logistics item, which are used for collecting accurate volume data of the logistics item and providing effective data support for logistics transportation. The method for measuring the volume of the logistics item provided by the embodiment of the invention comprises the following steps: collecting a depth image which is obtained by shooting a target logistics item through a depth camera; segmenting a target surface in the depth image, the target surface being a bearing surface for bearing a target logistics part; taking the target surface as a background region, performing foreground and background segmentation on the depth image, and taking an image corresponding to an obtained foreground region as the depth image of the logistics item; calculating a minimum cuboid surrounding the target logistics item according to the depth image of the logistics item; and calculating the volume of the minimum cuboid as a volume measurement result of the target logistics part.

Description

technical field [0001] The present application relates to the field of logistics, in particular to a method and a device for measuring the volume of a logistics item. Background technique [0002] Compared with traditional cameras, depth cameras (also known as depth cameras or 3D cameras) can detect the distance from each point in the image to the camera, and can detect the depth of field distance of the shooting space, which makes it easier to restore the real scene. Realize applications such as scene modeling. Typically, the depth camera can adopt three schemes of structured light, binocular vision or optical time of flight (Time Of Flight, TOF). [0003] In recent years, with the rapid development of related technologies such as machine vision, automatic driving, and face recognition, the application scenarios of depth cameras have become more and more extensive, especially the application requirements on mobile terminals are very strong. For example, in the field of lo...
