ADJUSTING MOTION CAPTURE BASED ON THE DISTANCE BETWEEN TRACKED OBJECTS

摘要

The technology disclosed relates to adjusting the monitored field of view of a camera and/or a view of a virtual scene from a point of view of a virtual camera based on the distance between tracked objects. For example, if the user's hand is being tracked for gestures, the closer the hand gets to another object, the tighter the frame can become—i.e., the more the camera can zoom in so that the hand and the other object occupy most of the frame. The camera can also be reoriented so that the hand and the other object remain in the center of the field of view. The distance between two objects in a camera's field of view can be determined and a parameter of a motion-capture system adjusted based thereon. In particular, the pan and/or zoom levels of the camera may be adjusted in accordance with the distance.

主权项

1. A method of controlling a camera using a distance of two objects in a 3D monitored space, the method including:
identifying from images captured by the camera first and second objects present in the 3D monitored space, the first and second objects at least partially within a field of view of the camera; repeatedly calculating spatial coordinates of the first and second objects present in the 3D monitored space based upon the images captured by the camera and calculating a distance between the first and second objects in space from the spatial coordinates; and responsive to the calculated distance, adjusting a camera parameter; whereby the camera is enabled to capture additional images of the first and second objects moving in space relative to the camera.
