Computer Vision in the Automotive Industry

Computer vision is a branch of artificial intelligence that teaches machines to understand and interpret visual data. Robots can accurately recognize and classify items using digital images from cameras and movies, together with deep learning models. They can also act on what they “see.”

The first computer vision experiments were carried out in the 1950s, using the first neural networks to identify an object’s edges and categorize basic objects like circles and squares. The first computer vision programmer to decipher typed or handwritten text was developed in the 1970s and used optical character recognition. For the blind, written text was translated using this invention.

As the internet developed in the 1990s, facial recognition software grew in popularity and made enormous collections of pictures accessible online for research. Thanks to these growing data sets, algorithms can now distinguish specific individuals in photos and videos.

Competition intensifies as there are more cars on the road. Each automaker works hard to create better vehicles. They are also worried about quantity, in addition. In 2021–2022, over 82,7 million cars were produced globally. But because so many cars are built, production mistakes are more likely now. How, therefore, may this issue be solved? In some of the top vehicle industries throughout the world, computer vision makes this possible.

But what exactly is this technology, and how does it help the sector? How might it be put to use? If you want to learn the answers to these queries, just read this article.

Deep Learning applications have shown great potential in the automobile sector, both inside and outside vehicles, such as during manufacturing, sales, and aftersales operations.

How is Computer Vision Work?

Computer vision technology generally imitates how the human brain works. But how does our brain identify things we see? One of the popular theories holds that our brains use patterns to decode certain items. Systems that use computer vision use this principle.

Pattern recognition is the foundation of modern computer vision algorithms. Computers are trained using enormous volumes of visual data, which is also used to process photographs, classify objects, and find patterns. For example, let’s send a million photos of flowers. The computer will analyze them, find patterns shared by all flowers, and create a model “flower.” As a result, anytime we send the computer photographs of flowers, we can discern whether they are flowers accurately.

In his work Image Processing and Computer Vision, the technical details of how computers comprehend Golan Levin provides images. Computers understand images as a collection of pixels, each having a unique set of colour values. Here is a picture of Abraham Lincoln as an illustration. Each pixel in this image has an independent 8-bit brightness value that ranges from 0 (black) to 255 (white) (white). When an image is uploaded, the software can identify these numbers. The computer vision algorithm in charge of subsequent analysis and decision-making receives this data as input

The Importance of Computer Vision to the Automotive Industry

Most industries put automation first. This goal aims to enhance product processing while minimizing manual labor. So how does machine vision contribute to achieving this goal? Examining the two most common functions listed below will teach you this:

Robotic guidance technology can find even the smallest 2D or 3D objects by using implanted optical sensors. Additionally, by creating a path, this method makes it easier to place fragile items. It also keeps a closer eye on critical activities than people do. This ensures that your business will become more productive without adding more manual labor.

Inspection: As already said, this technology makes identifying and classifying objects simple. As a result, computer vision is used in the care industry to check every step of production. Every manufactured product is checked for flaws, and those found are rejected. This covers surface detection (finding dents, scratches, etc.) and functional faults. It also requires confirming the presence or absence of car parts and examining the right sizes and shapes of those there. Last but not least, it continuously monitors every step of the product assembly process, helping to maintain the high calibre of each manufacturer.

The Development of Deep Learning

We must fully examine the algorithms that underlie computer vision technology to understand how it works today. Deep learning is a particular kind of machine learning that uses algorithms to discover patterns in data. It serves as the basis for contemporary computer vision. On the other hand, machine learning depends on AI, which is the basis for both technologies (check AI design best practices to learn more about design for AI).

Deep learning, which uses a specific neural network algorithm, is a more effective computer vision method. It makes use of neural networks to draw patterns from supplied data samples. The algorithms are based on our understanding of how brains work, namely how the neurons in the cerebral cortex are connected.

The perceptron, a mathematical representation of a biological neuron, is an essential building block of a neural network. There is potential for multiple layers of interconnected perceptrons, similar to biological neurons in the brain cortex. The perceptron network transmits input values (raw data) until they reach the output layer, which is a prediction or extremely accurate estimate about a certain object. For instance, after the investigation, the machine can categorize an object with X percent certainty.

For instance, to execute facial recognition, you would need to follow these steps

Establish a database: For each subject, you wanted to track, you had to gather distinct photos in a specific way.

Annotate photos: You would then need to add a tonne of important information for each image, such as the distance between the eyes, the width of the nasal bridge, the distance between the top lip and the nose, and dozens of other measurements that identify each person’s distinctive features.

Next, collecting new images from photographic or visual content would be essential. Then, you had to repeat the measurement process by emphasizing the image’s key features. It would help if you also considered the angle at which the photo was taken.

Automatic Vision System for Detecting Visual Defects

The automotive sector makes substantial use of computer vision in many applications to enhance the quality of the final product. Most customer product returns are because of aesthetic issues related to the painting. Operators often carry out the visual flaw detection process. A manual inspection takes time, is difficult, and is subjective.

Systems for automatic computer vision can look at the surface of manufactured parts like wheels. Real-time flaw identification can be accomplished using multiple cameras positioned above the production line. The devices keep an eye on the wheel’s coating intensity, looking for anomalies like a tiny decrease in the amount of paint that might signify an unexpected issue during the painting process.

How Long Does It Take To Understand An Image?

Simply put, not much. This justifies the intrigue surrounding computer vision: Even compute clusters in the past needed days, weeks, or even months to complete all the required computations. However, the process is lightning fast thanks to today’s super-speed CPUs, related gear, fast, dependable internet, and cloud networks. The willingness of some of the biggest companies performing AI research, including Facebook, Google, IBM, and Microsoft, to share their work has been a major factor. In particular, by open sourcing some of their machine learning work.

This allows others to expand on their work rather than start from scratch. Because of this, the AI industry is flourishing, and trials that took weeks can now be finished in just 15 minutes. Furthermore, for many real-world computer vision applications, this process is ongoing. It takes place in microseconds, which enables the so-called “situational awareness” of contemporary computers.

Inspection of Assembly Line Parts:

Deep learning has huge potential for part inspection and fault localization in AI vision applications for the automobile industry. Identifying improperly produced components, such as brake components, is essential before assembling any vehicle. Here, manual inspection is difficult to do without assistance.

Deep learning algorithms (Single Shot Detector – SSD, Faster RCNN) are more resilient in detecting numerous faults than traditional image processing techniques (Single Shot Detector – SSD, Faster Recurrent Convolutional Neural Networks). Transfer learning techniques were used to train a deep learning system for fault identification using a custom-collected dataset. They produced 95.6% accuracy on cylindrical grey shade brakes.

Application Areas for Computer Vision

Some people think that computer vision will play a significant role in design in the distant future. It’s untrue. Numerous areas of our lives already use computer vision. Here are a few notable examples of how we now use this technology:

Automotive

The automotive industry is undergoing a fundamental transition due to artificial intelligence. The speed of life has begun to quicken due to the integration of computer vision into the overall scheme of things in 2022. Self-driving and networked vehicles will be more common than in 2021, thanks to developments in computer vision technologies and implementations in 2022.

In 2022, computer vision will be primarily concerned with transforming autonomous vehicles into sophisticated visual readers, employing top-tier training data to fuel the algorithms and top-notch annotation techniques to improve the models over time.

As a result, we can expect that the in-car cameras will be able to recognize facial expressions more precisely, significantly reducing the likelihood of accidents. In 2022, computer vision will change how people see autonomous vehicles, influencing everything from seatbelt monitoring to creating dependent pedestrian tracking modules.

Content Structure

Computer vision systems currently aid content organizing. A good example is Apple Photos. We can traverse a more well-organized collection of images thanks to the application, which has access to our photo collections and automatically tags photos. Since it automatically provides a curated display of your favorite memories, Apple Photos is a great tool.

Facial Identification

Facial recognition technology matches people’s faces in face-to-face photos to their identities p. Important, often used objects contain this technology. Facebook, for instance, utilizes machine vision to recognize people in pictures.

A key biometric authentication method is face recognition. Presenting their faces to unlock their smartphones is a common feature of many mobile devices on the market today. Mobile devices scan this image and, depending on analysis, decide whether the person holding a device is authorized to use it. Front-facing cameras are used for face recognition. This technology’s biggest plus is how quickly it works

Touch Business

A few years ago, that could have seemed science fiction, yet nowadays, everything can be bought with the tap of a finger. Touch commerce enables customers to purchase directly from their mobile devices by fusing touchscreen technology and one-click ordering. After activating the service and connecting payment information to a general account, customers can purchase anything from clothing to furniture.

With sales of this kind expected to rise by 150 percent this year alone and retailers in virtually every industry anticipating a boost in revenue from this new technology, this is one of the most important advances in eCommerce in recent years.

Combined Reality

Applications for augmented reality require computer vision. With this technology, augmented reality (AR) applications may identify real-time objects (including surfaces and specific objects inside a physical place) and use this information to position virtual things in the real world.

Autonomous Vehicles

Automobiles can perceive their environment thanks to computer vision. An intelligent vehicle’s several cameras record videos from diverse perspectives and provides the data to computer vision software. Real-time video analysis by the system identifies traffic signals, surrounding objects (such as pedestrians or other vehicles), close road signs, etc. The autopilot function in Tesla vehicles is one of the most notable uses of this technology.

Healthcare

Computer vision has been making waves in the healthcare industry. The goal of this AI application, however, is to help medical companies produce very proactive tools and robots by 2022. Specific goals will be to spot severe conditions more quickly, measure blood loss precisely, improve diagnostic accuracy, and even provide better medical imaging standards.

Agriculture

Many agricultural organizations use computer vision to examine the harvest and provide solutions to common agricultural problems like weed emergence and nutrient shortage. Computer vision systems examine photos taken by satellites, aircraft, or drones to identify issues early and save significant financial losses.

Using the Edge

Edge computing will overtake cloud computing in some applications in 2022, especially when data privacy is crucial. In addition, computer vision in 2022 will seek to offer quicker responses because edge computing depends on on-premises technologies and real-time communications between the source and origin.

The broad use of Edge Computing in the next months will elevate Computer Vision to the status of a mainstream technology, reducing the existing lag between data identification, data categorization, and data interpretation.

Wrap-Up

In addition to the sectors already listed, supply chain management, manufacturing, three-dimensional imaging, surveillance, and data annotation will all be impacted by computer vision in 2022. AI and machine learning will make life easier for businesses and customers in the current and upcoming years, as well as in the near and distant future, as machines become smarter every day.
