Abstract:
1. A method for identifying a position of a platform comprising: identifying a first location of a feature in a first image in a series of images generated by a camera system on the platform while the platform is moving; identifying a second location of the feature in a second image in the series of images generated by the camera system on the platform while the platform is moving, wherein the second image is taken at a different time from the first image; determining whether the feature is moving in an environment in a field of view of the camera system; and identifying a difference between the first location of the feature in the first image and the second location of the feature in the second image, identifying a shift in a perspective of the camera system from the difference between the first location of the feature in the first image in the series of images and the second location of the feature in the second image in the series of images, and identifying a change in the position of the platform based on the shift in the perspective in response to a determination that the feature is not moving in the environment in the field of view of the camera system.
