Lecture 3

Question 1

Whare are the 3 types of pose estimation?

Answer 1

1. Direct (non-optimal) (no optimisation process)
2. Tracking the segments independently
3. Tracking the entire kinematic chain

Question 2

What is the direct pose esetimation method?

Answer 2

Calculate the coordinate system at the pelvis for EACH FRAME INDEPENDENTLY

Question 3

What are some issues with the direct pose estimation method?

Answer 3

• Needs the pelvis first
• Removes the medial epicondyle marker and place one on the thigh instead
• Add a ‘wand’

Question 4

How can you overcome the issues of the direct method?

Answer 4

Can use linear algebra to transform coordinate systems
