What are the main differences between 2D and 3D vision systems and when is each preferred?

• A. 2D vision uses flat images for detection; 3D vision adds depth for pose estimation and depth-based tasks; 3D is preferred for precise spatial reasoning.
• B. 3D vision uses only color information; 2D uses depth.
• C. 3D vision cannot detect pose.
• D. 2D vision uses flat images for detection; 3D vision adds depth for pose estimation and depth-based tasks; 3D is preferred for precise spatial reasoning.

Answer: (D)
