Problems solved by technology

Although various commercial capture systems have been able to track and record human motion with high spatio-temporal resolution, due to the very high cost of software, equipment and data acquisition process (wearing is troublesome, commercial equipment usually requires users to wear 40- 50 carefully placed reflective markers, or 18 magnetic or inertial sensors), in addition, they usually have special requirements and restrictions on the performers and the collection environment, making them unsuitable for home use; the existing human body pose reconstruction The steps of the method are cumbersome, and the equipment required is relatively expensive and the cost is high

Embodiment Construction

[0013] This specific embodiment adopts the following technical scheme: Its reconstruction method is:

[0014] (1) Download the pure human movement database: download the database information, and convert the downloaded database data from BVH format to TRC format;

[0015] (2) Establish human skeleton image: select the human skeleton image from the image converted to TRC format, then mark each joint point, and then connect the marked points to obtain a two-dimensional human skeleton model;

[0016] (3) Establish a three-dimensional human skeleton model: perform translation and rotation transformations on the two-dimensional human skeleton model obtained in step (2) for each posture, and construct the index of the output movement data after translation and rotation transformation, and extract the corresponding joint points Establish a three-dimensional human skeleton model from the data;

[0017] (4) Tracking the joint points of the three-dimensional human skeleton model: mark the joint...

Abstract

The invention discloses a human body posture rebuilding method, and relates to the technical field of human body postures. The human body posture rebuilding method comprises the steps that firstly, a pure human body movement database is downloaded; secondly, a human body skeleton image is established; thirdly, a three-dimensional human body skeleton model is established; fourthly, joints of the established three-dimensional human body skeleton model are traced; fifthly, the image is compared and corrected; sixthly, the human body posture is rebuilt in a three-dimensional mode. According to the human body posture rebuilding method, the rebuilding steps can be simplified, cost is low, operation is easy and convenient, and rebuilding is quick, easy and convenient.

Description

[0001] Technical field: [0002] The invention relates to the technical field of human body posture, in particular to a method for reconstructing human body posture. Background technique: [0003] Human motion capture technology has been widely used in animation production, movie special effects, computer games and other entertainment fields, bringing huge economic benefits. Although various commercial capture systems have been able to track and record human movements with high spatiotemporal resolutions, they require very high-cost software, equipment, and data collection processes (wearing is very troublesome, and commercial devices usually require users to wear 40- 50 carefully placed reflective marking points, or 18 magnetic or inertial sensors). In addition, they usually have special requirements and restrictions on the performers and the collection environment, which makes them unsuitable for home use; existing body posture reconstruction The method has complicated step...
