Abstract


In recent years, the rapid development of motion capture technology , how to make effective use of motion capture data has become many scholars hotspot . The technical sports redirect existing motion data is mapped to the new model of the target , and to ensure the reasonableness of the new generation movement , use of motion capture data is of great significance . Exercise redirect technology , from the point of view of maintaining the original motion characteristics , sports redirect method proposed for different situations . Resolution motion capture data based on the existing skeleton model is simplified to facilitate the movement redirect technology . The main work and innovation : Sports redirect method put forward a way of keeping the characteristics of the original trajectory . The foot motion redirect distortion , to solve this problem by adjusting the legs vector , lower limb movement to keep the footprint redirect , which keep the footprint is divided into the overall scaling of the original footprint and corrected overall maintained. Sports redirect method is proposed based on the trajectory of constrained optimization . The fundamental difference between redirect in the upper limbs and lower limbs , the redirect method based on optimization solving method of upper limb movement redirect , while incorporating the lower limb movement to achieve the redirection of the movement as a whole and for the characteristics and requirements of the upper limb . Proposed a technical framework based on the movement of the motion data classification redirect . How motion classification algorithm based on sports redirect , a the classified sports redirect the technical framework and use this framework the above sports redirect a movement to redirect the prototype system , verified motion redirect method effectively sex .
