Deep learning camera.

Cognex has introduced the world’s first industrial smart camera powered by Deep Learning software. This combination expands the possibilities of what can be successfully and precisely inspected in factory automation

Deep Learning and Artifical Intelligence (AI) are among the buzzwords not only in the manufacturing industry but also in many other fields. Deep Learning, a type of AI that leverages neural networks can be easily explained: Similar to how humans learn what a house is from a large number of examples, so too can a deep learning system come to understand the nature of an object from labeled images. Whether a car’s bumper, a package’s envelope, or something else, deep learning is an examples-based approach to solving inspection challenges. Furthermore, each inspection can be continually improved by feeding the existing algorithm with more example image data. This new data enhances the system leading to more accurate results.

Expanding the limits of automated inspection
Whether this is real intelligence or not, might be discussed by experts. From a practical point of view, the benefits for manufacturers are obvious and multiple. Manufacturers still rely on human inspectors throughout the production process because traditional machine vision systems cannot handle the complexity or variability within certain tasks. But humans can be prone to inconsistent results from one human to the next, or they can tire over the course of an eight hour shift. Additionally, there are many aspects throughout production that still go uninspected from one reason or another. Both of these realities open manufacturers up to quality control issues or the chances for recalls.

A vision system with integrated artificial intelligence, for example, is able to combine the judgement of a human inspector with the robustness and consistency of an automated solution for inspection or quality control. This is exactly the main advantage of the new In-Sight D900 vision system from Cognex.

As a first-of-its kind solution, it embeds Cognex’s deep learning software, known as In-Sight ViDi, inside an industrial-grade smart camera. This combination expands the possibilities of inline factory automation inspections.

Hardware: State-of-the art flexibility
The In-Sight D900 hardware is a compact, industry-grade smart camera that can easily be installed and deployed on the line without the need for a PC. The highly-modular, IP67-rated vision system includes field-changeable lighting, lenses, filters and covers that can be customized to match the individual application requirements.

For all three application tools, users can take advantage of the intuitive In-Sight spreadsheet interface allowing for a fast setup of Deep Learning applications without programming. The In-Sight spreadsheet simplifies application development and streamlines factory integration with a full I/O and communications function set. It also enables the ability to combine traditional Cognex rules-based vision tools (like PatMax Redline™) and Deep Learning tools in the same job, leading to quicker deployments.

Since In-Sight ViDi requires vastly smaller image sets and shorter training and validation periods than other deep learning solutions, applications are quick and easy to set up, teach, and deploy.

ViDi Read: Complex OCR

With the In-Sight ViDi Read tool, the user is able to solve challenging OCR applications in minutes. This module deciphers badly deformed, skewed, and poorly etched codes using optical character recognition.

This tool works right out of the box, dramatically reducing development time, thanks to the deep learning pretrained font library. The user simply defines the region of interest and sets the character size. In situations where new characters are introduced, this robust tool can be retrained to read application-specific characters that traditional OCR tools are not able to decode. In comparison to conventional vision systems without Deep Learning, this feature offers obvious advantages.

ViDi Check: Verifying assemblies and part location

Assembly verification
The ViDi Check tool on the In-Sight D900 allows manufacturers to perform fast and accurate assembly verification.

The system is able to detect complex features and objects. It verifies whether parts and kits are assembled correctly based on their location within a user-defined layout. The tool can be trained to create an extensive library of components, which can be located in the image even if they appear at different angles or vary in size.

ViDi Detect: Find defects and other unwanted variations

Airbag bad!
A third tool called ViDi Detect was designed for analyzing complex defect detection tasks.

It is able to learn from images of good parts in order to identify defective parts. In-Sight ViDi Detect is ideal for finding anomalies on complex parts and surfaces, even in situations where defects can be unpredictable in their appearance.

Summary: A new paradigm for high-quality vision inspections

The integration of the In-Sight ViDi deep learning based vision software on a smart camera helps factory automation customers easily solve challenging OCR, assembly verification, and defect detection applications that are often too difficult to deploy with traditional, rule-based machine vision tools and require reliable, fast and consistent results not possible with human inspection.

With the introduction of this system, Cognex addresses three application fields: optical character recognition (OCR), assembly verification and defect detection. Others might (and will) follow, but these three alone open up a wide range of possible tasks that the new system can tackle successfully and with more precision than a conventional vision system. With respect to the markets, the In-Sight D900 can be used across a range of industries including automotive, consumer electronics, consumer products, packaging, food and beverage, medical devices, and logistics.
