Fingertip interactive tracking registration method for AR assembly system

Aiming at the problems of single input mode and lack naturalness in assembly process existing AR systems, a tracking registration method mobile system is proposed based on multi-quantity multi-degree freedom natural fingertip interaction. Firstly, real-time stable hand area complex environment realized region tracking; secondly, detection recognition K-COS parallel vector used to improve precision stability recognition; thirdly, special movement track recognized improved DTW algorithm, which has strong compatibility feature gradient transformation for trajectory finally, through projection relationship between virtual object, interaction object made more realistic. The experimental results show that background, illumination, scale rotation, about 93%, motion template matching 91%. translation error visual reduced by 100pix compared with method, efficiency AR-guided 24.77% traditional manual assisted method. These data verifies practicability fingertips user's features guided assembly.
