Marco Jacobs, Vice President of Marketing at videantis, presents the "3D from 2D: Theory, Implementation, and Applications of Structure from Motion" tutorial at the May 2015 Embedded Vision Summit.
Structure from motion uses a unique combination of algorithms that extract depth information using a single 2D moving camera. Using a calibrated camera, feature detection, and feature tracking, the algorithms calculate an accurate camera pose and a 3D point cloud representing the surrounding scene.
This 3D scene information can be used in many ways, such as for automated car parking, augmented reality, and positioning. Marco introduces the theory behind structure from motion, provides some representative applications that use it, and explores an efficient implementation for embedded applications.
