Embodiment Construction

[0045] The present invention proposes a new motion synthesis system that uses a new metric that can measure the difference between two frames of different motion clips, regardless of the local coordinate frame of the motion.

[0046] figure 2A flowchart of a method of generating motion synthesis data from at least two recorded motion clips is shown in and further described below.

[0047] Motion graphics generated by this system can be used for path fitting purposes as well as avoiding obstacle objects. Figure 6 An exemplary application of the invention is shown. During path fitting ( Figure 6 a) The system according to the invention searches the motion graph for a given path GP and generates a composite motion to fit the path SP1 by concatenating motion segmentation nodes. When avoiding the obstacle object (b), when the synthetic motion is generated and the obstacle OB appears on the road, the system can automatically calculate the synthetic path SP2 avoiding the obstac...

Abstract

A method for generating motion synthesis data from two recorded motion clips comprises transforming (slO) the motion frames to standard coordinates, separating (s20) HF motion data of the motion frames from LF motion data, determining (s30) from different motion clips at least two motion frames whose frame distance is below a threshold, and defining (s35) a transition point between the at least two motion frames, interpolating (s40) motion data between said determined motion frames separately for HF and LF motion data, and generating (s50) a motion path from three segments: one segment is transformed motion data from a first motion clip up to the transition point, one segment is the interpolated motion data, and one segment is transformed motion data from a second motion clip, starting from the transition point.

Description

technical field [0001] The present invention relates to a method of generating motion synthesis data and a device for generating motion synthesis data. Background technique [0002] This section is intended to introduce the reader to various aspects of art, which may be related to various aspects of the invention that are described and / or claimed below. It is believed that this discussion is helpful to provide the reader with background information that will facilitate a better understanding of various aspects of the invention. Accordingly, it should be understood that these statements are to be read in light of this, and not as admissions of prior art. [0003] Animated humans are an important part of a wide range of media, and they are common in entertainment, training, visualization, and other applications. Animating human motion convincingly is difficult for two main reasons: motion itself is inherently complex, and human observers are very sensitive to errors because ...
