Computer Vision for Inventory Counting: Market Info

The global computer vision market was estimated at $9.45 billion in 2020. It is expected to reach $41.11 billion by 2030 at a CAGR of 16%. Market growth is spurred by the increasing demand for computer-vision-based inventory counting solutions across various industries, from manufacturing and retail to healthcare and logistics. The main drivers for the popularity of such solutions are the need for faster and more accurate inventory counting, optimized labor and equipment cost, and streamlined decision making on stock replenishment.

How Computer Vision for Inventory Counting Works

A sample architecture

Below, ScienceSoft shares a sample architecture of a computer vision solution for inventory counting, describes its key components and the inventory counting process.

Architecture of a Computer Vision Solution for Inventory Counting - ScienceSoft

A computer vision solution for inventory counting comprises the following components:

  • Data storage for captured images and video feeds of the inventory storage areas (e.g., shelves at the point of sale, racks in the warehouse) and production lines.
  • An image analysis system with a pre-trained convolutional neural network (CNN) at its core to recognize and quantify inventory items.
  • A decision-making module (reinforced with rule-based or AI-powered algorithms) to analyze inventory data and suggest proper further actions (e.g., SKU replenishment, item replacement, etc.).

The software integrates with:

  • Control systems of cameras (installed in the facility, on robots or drones, on mobile devices, etc.) to import digital images and videos.
  • An inventory management system, accounting software, and required case-specific systems, such as a merchandise management system (MMS), a warehouse management system (WMS), purchasing software, etc. to import relevant historical information and share inventory-related data and decisions.

How to do inventory count with computer vision

Inventory counting with computer vision typically involves the following steps:

  1. Real-time export of available images and video feeds from cameras to the database for storage and their instant transfer to the image analysis system for processing.
  2. Image preprocessing (noise reduction, contrast enhancement, etc.) to improve the quality of images.
  3. Feature extraction to determine lines, corners, edges, colors.
  4. High-level image processing (recognition, classification, counting of inventory items, etc.).
  5. Analysis of inventory ID, quantity, location, identification and quantification of empty storage space.
  6. Communicating data on current inventory levels and other essential details to the relevant systems and/or employees responsible for inventory-related tasks.

Main use cases of computer vision for inventory counting

Success Stories of Computer Vision for Inventory Counting

Sam’s Club improves inventory counting efficiency and avoids out-of-stocks

In 2022, Sam’s Club, a US-based wholesale retailer owned and operated by Walmart Inc., launched Inventory Scan, an inventory counting system powered with computer vision and AI. The solution enables real-time collection and processing of shelf images captured by autonomous robotic floor scrubbers. It analyzes stock levels and product localization, verifies planogram compliance and pricing accuracy, and integrates with a retailer’s existing inventory management system to automatically report inventory insights to the store managers.

Inventory Scan helped Sam’s Club improve inventory counting speed, cost, and accuracy across the retailer’s 600 stores by minimizing the need for labor-intensive and time-consuming physical counts. With real-time visibility of available inventory, Sam’s Club can now proactively manage stock replenishment and avoid stockouts and overstocking, which is expected to bring significant ROI for the retailer.

The product by a warehousing startup drastically improves inventory counting speed and cost

A US-based warehousing AI and robotics startup developed Gather AI, a computer-vision-based inventory counting system that relies on drones to capture images of the storage areas in the warehouses. Gather AI performs real-time image analysis, automatically counts inventory by reading QR-codes and barcodes, and alerts on unidentified items that require manual check.

The solution provides 15x faster inventory counting comparing to physical counting methods and drives substantial cost savings due to eliminated need for manual counting.

The startup raised $7.1 million in funding from 2017 to 2021. Gather AI was reported to scan 200% more pallet locations in the first quarter of 2022 than during the whole year of 2021, which reflects the product’s increasing popularity.

To deliver reliable computer vision solutions for inventory counting, ScienceSoft relies on a range of mature technologies, including:

The Challenges of Computer Vision for Inventory Counting

Challenge #1: The need to properly train an image analysis model

To ensure precise identification and quantification of inventory items, a CNN-based computer vision model requires a large inventory image dataset to be trained on and accurate fine-tuning at the training stage.



A training dataset for a CNN can be composed from the historical SKU images available in the inventory database. ScienceSoft recommends integrating an image analysis module with an inventory database to streamline the collection of inventory images. It will also help facilitate and speed up image dataset updates (when a large number of new SKUs is introduced) for the model’s further retraining.

Also, ScienceSoft recommends involving professional data scientists to train an image analysis model. They will accurately configure the model’s hyperparameters and initial weights to ensure that the model is not overfitted (that it’s capable of producing good results not only on training data, but also on real data).


Challenge #2: The need to smoothly integrate with various image sources

An image analysis system needs to collect storage area images from the hardware end users rely on. Thus, the solution has to seamlessly integrate with all the relevant camera control systems.



Easy-to-use integration APIs help a computer vision solution connect fast and smoothly to multiple image sources. However, legacy camera control systems may require custom-built integrations.


Challenge #3: Poor quality of storage area images

Low-resolution cameras and insufficient, non-uniform lighting can disrupt the quality of images and video feeds used for inventory counting, which affects items recognition and quantification accuracy.



Applying AI-powered image preprocessing algorithms (e.g., intelligent image base-sizing, decompressing, Gaussian smoothing, color processing, etc.) helps improve the quality of storage area images.

ScienceSoft can provide end customers with expert assistance on selecting the proper hardware and uniform illumination for the inventory storage facility, if required.


Costs of Computer Vision Software

The cost of developing a computer vision system for inventory counting varies greatly depending on:

  • The number and complexity of a solution’s functional modules.
  • The number and complexity of potential integrations with relevant software (e.g., camera control systems, an inventory management system, accounting software).
  • Availability of historical inventory images and their quality, which impacts the time and efforts required to train an image analysis model.
  • The amount of the storage area images used for analytics, which defines system scalability requirements.
  • Requirements for the image processing frequency (periodical or ongoing), which defines performance and availability requirements.
  • The number and complexity of web and/or mobile user applications.
Pricing Information

Based on ScienceSoft’s experience, custom computer vision software for inventory counting may cost around $150,000–$400,000+.

Average prices for computer vision hardware range from $120 to $2,000+, the lower applying to a static CCD camera and the upper – to a commercial drone with an embedded camera.
