VERNA has implemented a pilot project and demonstrated the ARUCO marker recognition system for one of the largest wholesale and retail chains of grocery and non-food stores.
The customer plans to use this technology as an auxiliary tool for accounting for the movement of goods inside the supermarket.
Our customer had the task of tracking the movement of cargo trolleys (rollcages) inside the supermarket warehouse between the areas of acceptance of goods, short-term storage, as well as areas of the trading hall and laying out. In the supermarket, such carts are usually about 200 pcs. They move products for laying out on the shelves. To reduce the time of finding products that require a strict temperature regime outside the refrigerator zone, it is necessary to control the movement of cargo carts.
Another function that the customer can solve with the help of this technology is the help of the store staff in quickly finding the rollcage with the right product and filling the supermarket shelves in a timely manner.
For these purposes, Verne specialists proposed to implement a video analytics system for ARUCO markers as the most appropriate. ARUCO markers are a synthetic square marker consisting of an internal binary matrix that defines its identifier. Due to the simple structure of the marker, the process of processing it is quite simple and fast.
We produced unique two-color black and white markers for the customer, placed them on roller cages, pre-entered the markers into the database, connected existing security cameras to the ARUCO code recognition video analytics system.
The system quickly and accurately recognizes the ARUCO code, determines its location and stores it in the log. By code number, the customer can at any time find objects of interest in the video archive, configure reaction rules, transfer data for processing to other software integrated with the video surveillance system.
All information about the time of arrival, unloading, movement between the laying areas enters the customer's management system and from there reports of responsible persons are generated according to the necessary criteria. The ARUCO codes used by us for this task are recognized from far distances and in low light conditions better than QR and BAR codes, which are rarely used for localization tasks due to redundancy and the need for high resolution. For the customer, there was no need to buy and use high-resolution cameras.
The first notice of ARUCO tokens appeared in 2014. ARUCO markers were originally developed to solve the problem of estimating camera orientation when used in various applications, including augmented reality applications.
Now this technology is often used in product production, in assembly shops, on the territory of factories, factories, greenhouses to account for types of goods, pallets and quick search in the archive.
In ARUCO warehouse complexes and logistics distribution centers, markers are used to track the movements of any product or batch of goods from the moment of receipt to shipment to customers.
