About this book

The evolution from 2D to 3D imaging represents one of the most significant technological advances in modern computing, enabling machines to perceive depth and understand the three-dimensional world around them with unprecedented accuracy.

For decades, cameras captured the world in two dimensions, recording only the intensity and color of light. While powerful for many applications, 2D imaging fundamentally lacks a critical dimension: depth. The human visual system achieves depth perception through binocular vision, where our two eyes provide slightly different views that our brain processes to estimate distances. Modern 3D image sensors bring this capability to machines, opening entirely new categories of applications from facial recognition to autonomous navigation.
