Embodiment Construction

[0060] In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

[0061] The three-dimensional interactive gesture sampling method provided by this application is based on the Markov chain Monte Carlo sampling method, and generates a large amount of real three-dimensional human interactive gesture data through a data-driven method. Through the present application, a large amount of real three-dimensional human interaction data can be generated, and the human posture space implied by the two-dimensional input data can be well covered. The three-dimensional interactive gesture sampling method of the present application can be used in a...

Abstract

The present application relates to a three-dimensional interactive gesture sampling method, device, computer equipment and storage medium. The method includes: obtaining a sampled video frame with annotations, the annotations being two-dimensional pose pairs; obtaining a priori function, and generating a three-dimensional likelihood function according to the sampled video frames with annotations; The three-dimensional likelihood function is used to construct the posterior probability density function; the preset initial three-dimensional pose pair is obtained, and according to the preset initial three-dimensional pose pair, the posterior probability density function is sampled by the Metropolis-Hastings sampling method , to obtain 3D pose pairs. This method generates a large number of three-dimensional interactive pose pairs by using video data that is relatively easy to obtain, and the operation is simple and the cost is relatively low.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular, to a three-dimensional interactive gesture sampling method, device, computer equipment and storage medium. Background technique [0002] Currently, there are many works on recovering 3D human pose from 2D data. It is not particularly difficult to obtain the geometry of the 3D pose of a single or isolated character. For example, 2D joints are automatically estimated from a single image, and 2D joints are fitted with a 3D statistical human model to obtain 3D pose and body shape. Or learn joint angle-constrained models from new motion capture data, including stretch poses. Various widely used models constrain the 2D-to-3D transformation of a single pose. [0003] However, when the collected objects are characters in motion, such as directly collecting data such as wrestling, Latin dance, etc. that contain a large number of three-dimensional human interaction p...
