Abstract
An image-based motion sensor includes a camera system and a processing system. The camera system is arranged for generating an image output including a plurality of captured images. The processing system is arranged for obtaining a motion sensor output by processing the image output, wherein the motion sensor output includes information indicative of at least one of a motion status and an orientation status of the image-based motion sensor. For example, information indicative of the orientation status of the image-based motion sensor may includes roll, pitch, and yaw related motion information, and information indicative of the motion status of the image-based motion sensor may includes speed, acceleration and displacement information.
