Abstract
Disclosed is a method and apparatus for searching a human three-dimensional (3D) posture which can rapidly and accurately search a human 3D posture by effectively representing the human 3D posture with a small amount of data. According to the method, a posture database is established by extracting posture descriptors using relation among respective joints of a body, and a feature of a query 3D posture is simultaneously extracted in the same manner. Then, the similarity is calculated by comparing the posture descriptor of the query 3D posture with the posture descriptors of postures in the posture database, and then outputted to search the human 3D posture.
Claims12
A method of searching a human three-dimensional (3D) posture, comprising:
- a posture descriptor extracting step of extracting a posture descriptor from a human query 3D posture using relation among respective joints of a human body;
- an other posture descriptor extracting step of extracting posture descriptors of human 3D models in a posture database in the same manner as the posture descriptor extracting step;
- a database establishing step of establishing the posture database with the posture descriptors of the human 3D models extracted at the previous step;
- a 3D model database establishing step of establishing a 3D model database using the human 3D models;
- a similarity comparing step of comparing an output query posture descriptor with the posture descriptors in the posture database;
- and
- a comparison result outputting step of outputting the 3D model database corresponding to the posture having the highest similarity in the posture database by indexing the similarity in accordance with a result of the similarity comparison at the previous step.
An apparatus for searching a human three-dimensional (3D) posture comprising:
- a posture descriptor extracting section for receiving a query 3D posture, and extracting a posture descriptor from the query 3D posture using relation among respective joints of a human body;
- another posture descriptor extracting section for extracting posture descriptors of respective postures of human 3D models by the same operation as the posture descriptor extracting section;
- a posture database establishing section for receiving posture descriptor data of the human 3D models from the posture descriptor extracting section and establishing a posture database;
- a similarity comparing section for comparing a difference between the posture descriptor of the query posture and the posture descriptors in the posture descriptor database;
- a 3D model database establishing section for establishing a 3D model database with human 3D models, and connecting the posture descriptor values in the posture database to the corresponding human 3D model values in the 3D model database, respectively;
- a comparison result indexing section for receiving comparison results from the similarity comparing section, and indexing the postures in the posture database according to a size of the similarity;
- and
- a comparison result outputting section for bringing out from the 3D model database, and outputting the 3D model which corresponds to the posture ranked to have the highest similarity by the comparison result indexing section.
