Abstract

The invention discloses an article space proportion estimation method and device, a terminal and a storage device, and the method comprises the steps: obtaining the images, photographed by a pluralityof cameras from different angles, of an article space, carrying out the pairing, and obtaining pairs of images; extracting a plurality of feature points from each image; matching each feature point of one image in the same pair of images with all feature points of the other image to obtain matched feature point pairs; and calculating the proportion of the article in the article space by utilizingthe matched feature point pairs. According to the invention, the images of the object are shot from different angles by the plurality of cameras, so that each angle of the object is covered, a visualblind area is prevented from influencing the final measurement result, and the measurement stability and accuracy are improved.

Description

technical field [0001] The present application relates to the technical field of logistics and warehousing, in particular to a method, device, terminal and storage device for estimating the space ratio of items. Background technique [0002] With the explosive growth of domestic express delivery business, the volume of parcels that express companies’ logistics transfer stations need to handle every day is also increasing explosively. Each logistics transfer station may have hundreds of slots, and each slot is It is used for loading and unloading packages, and it is particularly important to monitor the stacking volume of packages in each slot. Most of the logistics companies still adopt the method of manual monitoring and dispatching, that is, when there is a vacancy in a certain slot, arrange to dispatch the package to the slot, or when there are too many parcels in a certain slot, the problem of warehouse explosion occurs , to call the delivery vehicle to deliver the pack...
