Embodiment Construction

[0045] 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.

[0046] 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.

[0047] 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 for obtaining spatial positioning 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 performing standardization processing; predicting two-dimensional coordinates of key points from the single-person image by using a two-dimensional human body posture estimation method, predicting three-dimensional coordinates of the key points from the two-dimensional coordinates of the key points by using a three-dimensional posture generator, and obtaining a three-dimensional human body posture estimation result; meanwhile, obtaining human body parameters from the features of the two-dimensional human body posture estimation network; correcting the scale of the result of the three-dimensional human body posture estimation according to the human body parameters; calculating a visual angle deviation, and aligning a three-dimensional human body posture estimation result after rotation correction with a camera coordinate system; according to the perspective projection principle, absolute depth is fitted, obtaining space positioning, and finishing three-dimensional human body posture estimation. The result accuracy is improved and the system error is reduced.

Description

technical field [0001] The present invention relates to the technical field of computer vision, in particular to a method for estimating a three-dimensional human body posture for obtaining spatial positioning 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 bro...
