A method of image-tracking by using an image capturing device (). The method comprises: performing an image-capture of a scene () by using an image capturing device; and tracking movement () of the image capturing device () by analyzing a set of images by using an image processing algorithm ().

Image-based surface tracking

Method and apparatus are provided for image based positioning comprising capturing a first image with an image capturing device. Wherein said first image includes at least one object. Moving the platform and capturing a second image with the image capturing device. The second image including the at least one object. Capturing in the first image an image of a surface; capturing in the second image a second image of the surface. Processing the plurality of images of the object and the surface using a combined feature based process and surface tracking process to track the location of the surface. Finally, determining the location of the platform by processing the combined feature based process and surface based process.

Method and apparatus for image-based positioning

A method for performing point-to-point measurements includes (i) determining a distance to a first point and obtaining an image at a first pose, and (ii) determining a distance to a second point and obtaining an image at a second pose. The images have an overlapping portion. A change in pose between the first pose and the second pose is determined using observed changes between common features in the overlapping portion of the images and a scale associated with the images. A distance between the first point and the second point is determined based on the first distance, the second distance, and the change in pose between the first pose and the second pose.

Point-to-point measurements using a handheld device

A method of image-tracking by using an image capturing device. The method comprises: performing an image-capture of a scene by using an image capturing device; and tracking movement of the image capturing device by analyzing a set of images by using an image processing algorithm.
