Precision detection method of virtual reality motion capture system and related device

The invention discloses a precision detection method for a virtual reality motion capture system and a related device, and the method comprises the steps: building a three-dimensional coordinate of amotion capture sensor, obtaining the rotation angle data and position data of the motion capture sensor when the motion capture sensor is static, and carrying out the root-mean-square error calculation; obtaining a position jitter error and a rotation angle jitter error, and performing Airy variance analysis to obtain a random error term; meanwhile, obtaining rotation angle data and translation data of the motion capture sensor in a dynamic state, performing root-mean-square error calculation, and obtaining a rotation error and a translation error; and finally, using the position jitter error,the rotation angle jitter error, the random error term, the rotation error and the translation error as precision values of the motion capture system, and detecting the precision of the virtual reality motion capture system.
