| 发明名称 | Method and apparatus for movement estimation | ||
| 摘要 | A method for estimating movement of a mobile device includes: obtaining images from a camera communicatively coupled to a processor of the mobile device; identifying a stationary light source using at least one image of the images; calculating a displacement of the stationary light source based on a first location of the stationary light source in a first image of the images and a second location of the stationary light source in a second image of the images, the first image and the second image being captured at different times; and estimating movement of the mobile device based on the displacement. | ||

| 主权项 | 1. A method for estimating movement of a mobile device, the method comprising: obtaining a plurality of images from a camera communicatively coupled to a processor of the mobile device; identifying a stationary light source using at least one image of the plurality of images; calculating a displacement of the stationary light source based on a first location of the stationary light source in a first image of the plurality of images and a second location of the stationary light source in a second image of the plurality of images, the first image and the second image being captured at different times; and estimating movement of the mobile device based on the displacement. | ||
