Method and system for facilitating planogram compliance for inventory management

A system for facilitating compliance in a retail store with respect to planograms, the system comprises:

• a user interface for receiving a plurality of images for each product present in the retail store, wherein the plurality of images is stored in an inventory
• one or more hardware processors;
• a memory in communication with the one or more hardware processors, wherein the one or more first hardware processors are configured to execute programmed instructions stored in the one or more first memories, to:
• transform the plurality of images to create a plurality of augmented images, wherein the transformation comprises a photometric transformation and a geometric transformation;
• train a model using the plurality of images and a plurality of augmented images;
• provide a target image and a query image, wherein the target image is captured by a user from a shelf in the retail store and the query image is taken from the inventory;
• extract a plurality of feature points from the target image and the query image using a feature extraction method;
• match the plurality of feature points from the target image and the query image to get a set of matching pairs on the basis of a similarity score;
• calculate a center and a scale for each pair of the set of matching pairs;
• generate region proposals for each pair using a set of centers and the corresponding scales, wherein the set of centers are identified using points where a large number of centers are clustered based on a threshold;
• calculate a classifier similarity score by classifying the generated region proposals using the trained model;
• identify overlaps among all the generated regions proposals, wherein the overlap is measured by an intersection area over a union (IOU) of two adjacent region proposals which are above a threshold;
• identify a single region for every detected overlaps using non-maximal suppression (NMS), wherein the identified single region is indicative of the detected products and their respective bounding boxes;
• collate all the single regions for all query images to get a realogram;
• and
• compare the realogram with the planogram to generate a planogram compliance report indicative of the planogram compliance for inventory management in the retail store.

One or more non-transitory machine-readable information storage mediums comprising one or more instructions which when executed by one or more hardware processors cause:

• receiving, a plurality of images for each product present in the retail store, wherein the plurality of images is stored in an inventory;
• transforming, the plurality of images to create a plurality of augmented images, wherein the transformation comprises a photometric transformation and a geometric transformation;
• training, a model using the plurality of images and a plurality of augmented images;
• providing, a target image and a query image, wherein the target image is captured by a user from a shelf in the retail store and the query image is taken from the inventory;
• extracting, a plurality of feature points from the target image and the query image using a feature extraction method;
• matching, the plurality of feature points from the target image and the query image to get a set of matching pairs on the basis of a similarity score;
• calculating, a center and a scale for each pair of the set of matching pairs;
• generating, region proposals for each pair using a set of centers and the corresponding scales, wherein the set of centers are identified using points where a large number of centers are clustered based on a threshold;
• calculating, a classifier similarity score by classifying the generated region proposals using the trained model;
• identifying, overlaps among all the generated regions proposals, wherein the overlap is measured by an intersection area over a union (IOU) of two adjacent region proposals which are above a threshold;
• identifying, a single region for every detected overlaps using non-maximal suppression (NMS), wherein the identified single region is indicative of the detected products and respective bounding boxes;
• collating, all the single regions for all query images to get a realogram;
• and
• comparing, the realogram with the planogram to generate a planogram compliance report indicative of the planogram compliance for inventory management in the retail store.
