Document Type and Number:
Japanese Patent JP7000555
Kind Code:
B2
Abstract:
Embodiments of the present application disclose a method for determining pose information of an image capturing device, including: acquiring, by an image capturing device, a first image of a target object; extracting, by the image capturing device, coordinate information of a first two-dimensional (2D) key point corresponding to the target object from the first image; acquiring, by the image capturing device, a second image of the target object; acquiring, by the image capturing device, coordinate information of a second 2D key point in the second image according to the coordinate information of the first 2D key point; acquiring, by the image capturing device, coordinate information of a three-dimensional (3D) key point corresponding to the target object; and determining, by the image capturing device, camera pose information of the second image according to the coordinate information of the first 2D key point, the coordinate information of the second 2D key point, and the coordinate information of the 3D key point. In the embodiments of the present application, more key points can be obtained during the estimation of camera pose information, so that errors in camera pose information are reduced, and a tracking loss because of an excessively small quantity of key points in tracking can be avoided.
