Determining shape and motion from monocular camera: A direct approach using normal flows

作者：

Highlights：

• We determine camera motion and shape directly from normal flows.

• Our method does not require optical flows or feature correspondences.

• Two constraints are developed to determine camera motion.

• Experimental results are comparable to the state-of-the-art methods.
