AI Technical Summary
Existing technologies lack an accurate evaluation method that is simple to operate, cost-effective, and applicable to the pose and trajectory accuracy of different VR devices, especially in evaluating the 6-DOF positioning and pose determination technology, tracking accuracy, and stability of VR devices in confined spaces.
By combining the Vicon motion capture system and the robotic arm system, the pose trajectory of the VR device is acquired through multiple fixed infrared cameras and a movable robotic arm. The timestamps are aligned using angular velocity modulus and Pearson correlation coefficient, and spatial and scale alignment is performed based on the hand-eye calibration principle. The difference between the two pose trajectories is calculated to achieve a comprehensive evaluation.
It achieves high-precision pose trajectory evaluation of VR devices in confined spaces. It is simple to operate, low in cost, and has a wide range of applications, suitable for VR device positioning accuracy evaluation in different scenarios.
