Abstract
The present invention relates to a human body animation system based on video frequency. Said system includes video collecting device and colour leotard. The described video collecting device includes video output port of digital camera and video input port of video collecting card which are connected by using twisted pair cable, in which the video collecting card is mounted in the computer. Said invention also provides its advantages and application.
Description
The present invention relates to multimedia application, relate in particular to a kind of human body animation system based on video.
Traditional human body animation is called the joint animation again.Joint model refers to the expression of the first tree of a kind of n, and its each interior nodes is the rotary joint with one degree of freedom.The motion in joint can be controlled by the method for direct kinematics or inverse kinematics.Direct kinematics is by the joint rotation angle is provided with the position that key frame obtains each limbs of associated.Inverse kinematics then is by the given end joint position, is calculated the position in each middle joint automatically by computing machine.Though it is simple than the former, along with the increase of facet joint complex degree, its cost of finding the solution will be huge.Can see that the joint animation not only needs animation teacher's loaded down with trivial details work, and calculated amount is very big.Because it is just to a kind of simulation of real human body motion, the final human motion that obtains often lacks the sense of reality.
The joint animation of comparing, the animation that obtains based on motion is just becoming more and more common, when going on the stage is made specific action, be attached to the performer on one's body the sensor of each joint part joint position can be returned to computing machine.These data are acted on the three-dimensional (3 D) manikin just obtained real human motion.Though this technology can produce more real human motion than joint animation, but its process of obtaining movable information is often costly, needs special operating room again, perhaps has cable to be attached on the human body, and this has limited performer's free movement, causes action distortion to a certain degree.
The purpose of this invention is to provide a kind of human body animation system based on video.
The present invention takes following measures in order to achieve the above object:
Human body animation system based on video comprises video acquisition device and colored tight, said video acquisition device is to connect the video output of digital camera and the video input port of video frequency collection card with twisted-pair feeder, wherein, video frequency collection card is mounted in the main frame of computing machine, and join with display, video camera is installed on the crane; Said tight front is provided with the blue circle formula of neck color lump from top to bottom successively, right shoulder purple saddle color lump, left side shoulder brown saddle color lump, chest black color lump, the blackish green chromosphere formula of right elbow color lump, the yellow circle formula of left side elbow color lump, the blackish green color lump of pelvis, preceding right arm purple color lump, preceding left arm brown color lump, the light green circle formula of right finesse color lump, left finesse cyan circle formula color lump, right knee brown circle formula color lump, the yellow circle formula of left side knee color lump, the blue circle formula of right ankle color lump, left side ankle black circle formula color lump, the back side also is provided with back black color lump from top to bottom successively, the blackish green color lump of back pelvis, back left arm brown color lump, back right arm purple color lump.
Advantage of the present invention: efficient, economical, and it is unrestricted to move, and in the research to human motion analysis in computer vision field, we have obtained inspiration, have developed the human body animation technology based on video.In different applications, our method can be at different video kinds.When the field that needs the least possible animation teacher manual intervention at some, we have made a tight, and color block is all sticked in the place corresponding to the different human body position on it.After utilizing the video acquisition device collection to put on model's the video of motion of this tight, system just can automatically handle this video.Finally, we can obtain three-dimensional motion information according to human motion situation in the video flowing, and set up the movable information storehouse, and the animation teacher just can generate new human body animation according to existing movable information like this.
Below in conjunction with accompanying drawing the present invention is elaborated.

Fig. 2 is the video acquisition device synoptic diagram;
Fig. 3 (a) is colored tight Facad structure synoptic diagram;
Fig. 3 (b) is colored tight structure synoptic diagram.
Human body animation system based on video comprises video acquisition device and colored tight, said video acquisition device is to connect the video output of digital camera 24 and the video input port of video frequency collection card 22 with twisted-pair feeder 23, wherein, video frequency collection card is mounted in the main frame 21 of computing machine, and join with display 20, video camera is installed on the crane 25; Said tight front is provided with the blue circle formula of neck color lump 1 from top to bottom successively, right shoulder purple saddle color lump 15, left side shoulder brown saddle color lump 2, chest black color lump 14, the blackish green chromosphere formula of right elbow color lump 13, the yellow circle formula of left side elbow color lump 3, the blackish green color lump 4 of pelvis, preceding right arm purple color lump 12, preceding left arm brown color lump 5, the light green circle formula of right finesse color lump 11, left finesse cyan circle formula color lump 6, right knee brown circle formula color lump 10, the yellow circle formula of left side knee color lump 7, the blue circle formula of right ankle color lump 9, left side ankle black circle formula color lump 8, the back side also is provided with back black color lump 16 from top to bottom successively, the blackish green color lump 17 of back pelvis, back left arm brown color lump 19, back right arm purple color lump 18.
