Method and system for judging whether goods exist in goods allocation or not through vision

Abstract

The invention relates to a method and a system for judging whether goods exist in a goods allocation or not through vision. The method comprises the following steps: calibrating the goods allocation in a shot picture of the to-be-judged goods allocation; taking a shot picture when the to-be-judged goods location is empty as a reference picture; determining the edge of the goods location in the reference picture through filtering; comparing the calibrated shot picture of the to-be-judged goods allocation with a reference picture for determining the edge of the goods allocation to obtain a reference picture for determining the position of the goods allocation; recording the gray scale standard of each region when the goods allocation is empty; collecting a field picture of the to-be-judged goods location in real time; recording a gray scale standard of each region of the field picture for determining the goods allocation position; comparing the gray scale standard of each region when the goods allocation is empty with the gray scale standard of each region corresponding to the field picture for determining the position of the goods allocation; and judging whether goods exist in each goods allocation or not according to the gray difference value of each region corresponding to each goods allocation. According to the invention, the cost of judging whether goods exist in the goods allocation is reduced.

Description

technical field [0001] The invention relates to the technical field of visual judgment, in particular to a method and system for visually judging whether a cargo space is available. Background technique [0002] In the field of production logistics, the storage of materials is placed in the ground cargo space or shelf grid by means of pallets or packing boxes. In order to facilitate the management and inspection of the information system, the information system needs to clearly know the storage space or Whether the shelf grid is empty or in stock. [0003] At present, the main technical way to determine whether a storage space or shelf is empty is to use photoelectric inspection technology such as photoelectric sensors. By placing a photoelectric sensor in each empty space and shelf grid to know whether it is empty or full, the detection efficiency and accuracy are very high, but there are The problem is that wiring and installation are required, and because of technical re...

[0003] At present, the main technical way to determine whether a storage space or shelf is empty is to use photoelectric inspection technology such as photoelectric sensors. By placing a photoelectric sensor in each empty space and shelf grid to know whether it is empty or full, the detection efficiency and accuracy are very high, but there are The problem is that wiring and installation are required, and because of technical requirements, the sensor needs to protrude from the ground or the shelf, which will have a certain impact on the passage of the ground or the use of the shelf, and the wiring installation on the ground needs to be dug, which not only causes damage to the ground, It also increases construction costs

Once the construction is completed, if there is a change in the position of the goods or shelves, or if there is a problem with the equipment line, the cost of adjustment and maintenance will also be high
