Title: Pose determination method and device, intelligent apparatus, and storage medium
Inventor: LIN XIANGKAI
IPC: G06T7/73
Filed: 2019-03-22
Abstract: The present invention relates to the technical field of computers. Disclosed in an embodiment of the present invention are a pose determination method and device, an intelligent apparatus, and a storage medium. The method comprises: acquiring, by means of tracking a feature point of a first anchor image, a pose parameter of an image captured by a camera; if an image preceding a first image satisfies a feature point tracking condition while the first image does not satisfy the feature point tracking condition, taking the image preceding the first image as a second anchor image; acquiring, by means of tracking a feature point of the second anchor image, a pose parameter of the image captured by the camera with respect to the second anchor image; and acquiring a pose parameter of the image according to the pose parameter of the image with respect to the second anchor image and a pose parameter of each anchor image with respect to a preceding anchor image, and determining a pose of the camera according to the pose parameter. In the invention, another anchor image is used when a first image does not satisfy a feature point tracking condition, thereby preventing the problem in which a feature point is unable to be tracked due to too many changes in a position or an orientation of a camera, enhancing robustness, and increasing tracking precision.
