Problems solved by technology

[0008] However, this method requires the target object to be stationary in order to take images for extracting key points, and when using this method, it must be equipped with a binocular camera, which is very inconvenient. When using method 2 at the same time, only rigid body Moving target object for pose positioning

Embodiment Construction

[0083] In order to efficiently and accurately locate the pose of the target object in the video, in the embodiment of the present disclosure, the electronic device first obtains the initial pose, the first video frame and the second video frame containing the specified target object, based on the obtained Including the initial pose of the specified target object, the first video frame and the second video frame, two different calculation methods are used to calculate each feature point of the target object, and each feature point of the target object is obtained in the first Based on the first two-dimensional coordinate information and the second two-dimensional coordinate information in the video frame, a target pose positioning result of the target object in the first video frame is obtained based on the first two-dimensional coordinate information and the second two-dimensional coordinate information.

[0084] In practical applications, the above-mentioned electronic devices...

Abstract

The invention relates to a pose determination method and device, electronic equipment and a storage medium, which are used for efficiently and accurately determining the pose of a target object in a video, and the method comprises the following steps: obtaining an initial pose containing a specified target object, a first video frame and a second video frame, and adopting two different calculation modes to calculating each feature point of the target object to obtain first two-dimensional coordinate information and second two-dimensional coordinate information of each feature point of the target object in the first video frame, and obtaining a target pose positioning result of the target object in the first video frame based on the first two-dimensional coordinate information and the second two-dimensional coordinate information.

Description

technical field [0001] The present disclosure relates to the field of computer science, and in particular to a pose determination method, device, electronic equipment and storage medium. Background technique [0002] With the development of Augmented Reality (AR) technology, the interaction between virtual information and the real world becomes more frequent. For example: when recording a fun video, add virtual props to human hands. [0003] In practical applications, in order to make the interaction between virtual information and the real world more realistic, it is necessary to perform pose positioning on human body parts, objects, etc. in the real world. [0004] Under related technologies, the commonly used pose positioning methods include the following two types: [0005] Method 1: Based on the point features and line features of the two-dimensional image, the observed image frame and the template image frame are matched to obtain the matching result. Based on the ma...
