What is 6D pose estimation of an object?

6D pose estimation of an object is the task of determining its position and orientation in three-dimensional space. "6D" means six degrees of freedom:

• 3 coordinates of position (X, Y, Z)
• 3 angles of orientation (for example, Euler angles or quaternions)

In robotics and computer vision, this is important for precise interaction with objects, such as for a manipulator to grasp them. 6D pose estimation algorithms analyze data from cameras or sensors to determine exactly where and how the object is oriented relative to the robot or scene.
