Examples of Machine Vision

Quality Inspection in Manufacturing: Machine vision is widely utilized in manufacturing facilities to inspect and verify product quality automatically. It is often integrated into assembly or production lines to examine items for defects, accurate measurements, and proper labeling. For example, in the automotive industry, machine vision systems can inspect the shapes, dimensions, and surface finishes of various parts like engines and car frames to ensure adherence to specified requirements.

Facial Recognition Systems: Machine vision technology plays a crucial role in the development and operation of facial recognition systems, such as those used in surveillance, access control, and smartphone applications. These systems utilize cameras and specialized algorithms to capture, analyze, and compare facial features against pre-existing databases for identification and authentication purposes.

Autonomous Vehicles: Machine vision is an integral part of self-driving cars and other autonomous vehicles’ functioning. Cameras, LiDAR, and other sensor systems capture information about the surroundings, allowing the vehicle to recognize lanes, other vehicles, pedestrians, traffic signals, and other critical elements in real-time. This continuous stream of data is analyzed and processed, enabling the autonomous vehicle to make decisions regarding navigation, acceleration, and braking, thus making our roads safer.
