Embodiment Construction

[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by the embodiments of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0037]It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element. In addition, the connection can be used for both fixing function and circuit communication function.

[0038] It is to be understood that the terms "length", "width", "top", "bottom", "front",...

Abstract

The invention provides a three-dimensional human body posture estimation method and a computer readable storage medium. The method comprises the following steps: acquiring a single-person image from an original image by adopting a human body detection network and carrying out standardization processing on the single-person image; predicting two-dimensional coordinates of the key points from the single-person image by using a two-dimensional attitude estimation method; generating a three-dimensional coordinate from the two-dimensional coordinate, including: predicting a first three-dimensional coordinate of the key point by using a three-dimensional attitude generator; performing symmetric processing on the two-dimensional coordinates according to a symmetric structure of a human body joint, and predicting second three-dimensional coordinates of the key points by using a three-dimensional attitude generator; enabling the first three-dimensional coordinate and the second three-dimensional coordinate to respectively calculate difference values with the corresponding labels, the sum of the results bing used for back propagation, and obtaining three-dimensional human body posture estimation. A connection relation and a symmetric relation between key points of a human body are fully utilized, and the purpose of optimizing a prediction result can be achieved; and meanwhile, on the basis of an original data set, the expansion of training data is realized, and the robustness of the model is enhanced.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a method for estimating a three-dimensional human posture and a computer-readable storage medium. Background technique [0002] It is a very valuable research direction in the field of computer vision to estimate the human body pose on a two-dimensional RGB image containing a portrait, that is, to output the coordinate position of the key points of the designated human body according to the image information. The detection results of human pose estimation can further serve many industrial fields such as human body reconstruction, human-computer interaction, behavior recognition, virtual reality, game modeling, etc., and have been applied to many products. Compared with two-dimensional attitude, the result of three-dimensional attitude estimation can provide higher-dimensional and richer information in application, and has broad application prospects. Therefore, in recent...
