Automatic checking system for stereoscopic warehouse

Abstract

The invention relates to an automatic inventory checking method for a three-dimensional warehouse. The method comprises the following steps that S1, a remote control terminal learns, trains and establishes a goods specification model; s2, the carrying equipment moves one stack to the position of a stacking platform to trigger a photoelectric sensor; s3, the remote control terminal receives the trigger signal to control the 3D camera to collect first image information of the goods; s4, the remote control terminal controls the 2D camera to collect second image information of the stacked goods; s5, the remote control terminal completes goods checking based on the image information and the volume information of the goods; and storing the inventory result data. By means of the method, the functions of automatic sensing, automatic specification identification, automatic image acquisition, automatic box number calculation and automatic data storage of the stacks can be achieved, and therefore stack data can be obtained under the condition of no human intervention, namely automatic checking is achieved.

Description

technical field [0001] The invention belongs to the technical field of warehouse goods inventory, and in particular relates to an automatic inventory inventory method and system for a three-dimensional warehouse. Background technique [0002] The three-dimensional warehouse has a wide range of applications in the logistics industry. It has the characteristics of safety, high degree of automation, and small footprint. However, how to efficiently count the goods stored in the three-dimensional warehouse has always been an unsolved problem. At present, the three-dimensional warehouse inventory generally adopts the manual inventory method. The process is: use a stacker to take down the goods in each cargo space, manually count them, and then put the goods back into the cargo position. For a large-scale stereo library, the efficiency of this process is very low. Generally speaking, it takes at least one week for a typical large-scale stereo library to perform a complete inventor...

Problems solved by technology

But this method has two disadvantages: 1. The space in the three-dimensional warehouse is narrow. For some large-scale multi-layer stacks, images can only be collected from the top, and it is impossible to complete the images from the four sides through the camera; 2. If only from The image is taken from the top but cannot be taken from the side. Because the 2D image cannot directly obtain the three-dimensional height information of the object, it is impossible to judge the number of stacked layers, so that it is impossible to calculate the total number of boxes stacked
