Abstract

The embodiment of the invention discloses a method and device for determining the posture of a camera, electronic equipment and a computer readable medium. One specific embodiment of the method comprises the following steps: extracting feature points of at least two frames of images; based on the extraction of the feature points, determining a homography matrix between two adjacent frames of images; determining a plane normal vector according to the homography matrix between the adjacent images; determining a homography matrix between a plane corresponding to the plane normal vector and the target image; determining a homography matrix between the at least two frames of images and the plane according to the homography matrix between the plane of the plane normal vector and the target imageand the homography matrix between the two adjacent frames of images; and processing the homography matrix between the at least two frames of images and the plane to obtain the poses of the cameras corresponding to the at least two frames of images. According to the embodiment, the camera attitude is determined by estimating the normal plane of the plane and tracking the feature points.

Description

technical field [0001] Embodiments of the present disclosure relate to the field of computer technology, and in particular to a method, device, device, and computer-readable medium for determining camera poses. Background technique [0002] Camera pose, that is, the position of the camera in space and the orientation of the camera. The pose of the camera can be regarded as the transformation of the camera from the original position to the current position, including translation transformation and rotation transformation, which is the position of the rigid body in space and its own posture. Currently, the determination of the camera pose is done by knowing the normal vector of the image plane and by fixing the horizontal plane in the image. But the normal vector to the plane is unknown in the image. Contents of the invention [0003] The Summary of the Disclosure is provided to introduce concepts in a simplified form that are described in detail in the Detailed Descriptio...
