Computer vision refers to the AI technology that enables computers to interpret and understand visual information from the world. With regard to Augmented Reality, computer vision plays an important role as any AR system needs to be trained to understand its environment in order to be able to accurately place digital content in the correct location.
Common computer vision techniques include image processing, feature extraction, and pattern recognition,
In a nutshell, without computer vision, SLAM as well as image and object recognition/tracking wouldn’t even be possible.
