A New Interactive Simulation Method for Virtual Tape Measurement

The virtual tape measurement is an extremely important process in the industrial training systems, and the fidelity of the measurement depends on the stability of the grasp and the accuracy of the tape measure. Combined with the virtual hand, a new interactive simulation method for the virtual tape measurement is proposed and applied to the wind-driven generator alignment training simulation system. The fusion of the geometric rules and physical rules improves the grasping judgment method, and the quaternion adjusts the grasp gesture. Based on the 3D algorithm, the tape width uneven is solved by optimizing the vertex setting to generate a smooth ruler. The experimental results show that our method is effective, and could greatly improve the virtual training effect with the accurate and natural grasping and the realistic tape simulation result.
