Abstract:
Methods and devices for camera aided motion direction and speed estimation are disclosed. The method of determining position characteristics of a mobile device comprises capturing a plurality of images that represent views from the mobile device, adjusting perspectives of the plurality of images based at least in part on an orientation of the mobile device, determining a misalignment angle with respect to a direction of motion of the mobile device using the plurality of images, and storing the misalignment angle and the direction of motion in a storage device.
