METHOD AND APPARATUS FOR GENERATING DANCE MOTION BASED ON POSE AND TIMING CONSTRAINTS

摘要

The present invention relates to a method and apparatus for generating dance motion based on pose and timing constraints. A method and apparatus for generating dance motion based on pose and timing constraints according to an embodiment of the present invention can, when a user assigns pose to the music for authoring dance choreography, search poses including the most similar pose and select poses having high connectivity to naturally connect them.

1. An apparatus for generating dance motion based on timing and pose constraints comprising:
a pose data receiving part configured to receive at least one pose data and time information corresponding to each of the plurality of the pose data from a user; a similar pose candidate data searching part configured to determine a similar difference value between the received pose data and each pose of the plurality of motion data stored in motion database and select similar pose data of which the similar difference value is equal to or less than a threshold as similar pose candidate data; a motion clip generating part configured to acquire motion clip candidates, which including pose similar to the received pose data, from the similar pose candidate data based on timing constraints according to the time information; a connectable motion clip selecting part configured to calculate direction and speed similarity, and relationship similarity of the previous motion clip and the motion clip candidates, calculate the final similarity by providing constant weight values to the similar difference value, the direction and speed similarity and the relationship similarity, and select the connectable motion clip of which the final similarities are equal to or less than a threshold; and a motion clip connecting part configured to arrange the selected connectable motion clips in motion connecting blocks, estimate positions of joints of next connectable motion clip by controlling position of root joint of the next connectable motion clip, and connect the next connectable motion clip by calculating joint angles from the estimated positions of joints.
