2D and 3D camera technologies
2D and 3D camera technologies are at the heart of powerful machine vision systems. They enable precise quality control, efficient process automation, and reliable error detection in industrial image processing.
2D camera technology
Area scan cameras capture the scene in a single shot. Line scan cameras scan the image line by line. The image is displayed as a monochrome or color image (RGB). 2D image processing is particularly effective when capturing scenes with high contrast and clear structures.
3D camera technology
3D cameras also capture depth values and offer new possibilities in robotics, automation, and medicine. The third dimension is becoming increasingly important for complex tasks. 3D solutions are also established in entertainment and virtual reality.
Typical areas of application for 2D and 3D cameras
2D and 3D machine vision cameras are used for different tasks in industrial image processing. While 2D cameras are primarily used for checking flat, high-contrast objects and fast inspection tasks, 3D cameras enable the precise detection of shapes, volumes, and positions in the third dimension. They are therefore ideal for complex automation and robotics applications.
