The embodiments of the disclosure provide a tracking accuracy evaluating system, a tracking accuracy evaluating device, and a tracking accuracy evaluating method. The method includes: detecting multiple distances between the tracking accuracy evaluating device and multiple reference positions in a rotating process associated with a rotating axis, wherein an accommodating space of the tracking accuracy evaluating device accommodates a tracking device during the rotating process, and the distance sensor, the rotating axis, and the tracking device accommodated in the accommodating space have a fixed relative position therebetween; estimating a first pose variation of the tracking device during the rotating process based on the distances and the fixed relative position; obtaining a second pose variation of the tracking device during the rotating process; and determining a tracking accuracy of the tracking device based on the first pose variation and the second pose variation.

Tracking accuracy evaluating system, tracking accuracy evaluating device, and tracking accuracy evaluating method

A tracking method for tracking a head-mounted device includes following steps. First pose data of the head-mounted device is tracked in an inside-out coordinate system. Second pose data of the head-mounted device is tracked in an outside-in coordinate system. A transformation relationship between the inside-out coordinate system and the outside-in coordinate system is calculated according to the first pose data and the second pose data. The first pose data in the inside-out coordinate system is transformed into third pose data in the outside-in coordinate system according to the transformation relationship. In response to that the second pose data is currently available, the second pose data is utilized to determine a device pose of the head-mounted device. In response to that the second pose data is currently unavailable, the third pose data is utilized to determine the device pose of the head-mounted device.
