TRACKING SYSTEM CALIBRATION WITH MINIMAL USER INPUT
摘要
To calibrate an positional sensor, a plurality of image locations and image sizes of a tracked object are received as the tracked object is moved through a rich motion path. Inertial data is received from the tracked object as the tracked object is moved through the rich motion path. Each of the plurality of image locations is converted to a three-dimensional coordinate system of the positional sensor based on the corresponding image sizes and a field of view of the positional sensor. An acceleration of the tracked object is computed in the three-dimensional coordinate system of the positional sensor. The inertial data is reconciled with the computed acceleration, calibrating the positional sensor.
