What is 3D computer vision?

3D computer vision involves using algorithms and systems to interpret and understand three-dimensional structures from visual data like images or videos. It enables machines to analyze depth, shape, and spatial relationships in a scene. Applications range from object recognition to 3D scene reconstruction. A key aspect is depth estimation, which determines the distance of objects from the camera. Techniques include stereo vision, which uses two camera views, and depth sensors like LiDAR. These methods are essential for creating 3D models of environments in applications like robotics and augmented reality. Another critical use is motion analysis. By tracking objects in 3D space, systems like self-driving cars can make real-time decisions based on their surroundings. 3D computer vision also supports virtual reality by enabling realistic scene rendering and interaction.
