SYSTEM AND METHOD FOR FOCUSING IMAGING DEVICES

摘要

A system and method for automatically focusing imaging devices on an imaging set employs at least one tracker and two or more tracking markers, each tracking marker having an identification means and a tracking pattern. The tracking markers are configured for attaching to the imaging devices and to corresponding subjects to be imaged. A tracker gathers image information of the imaging set and provides it to a controller, which compares the image information to predetermined stored information about the tracking patterns of the various tracking markers. The tracking markers are identified and their three-dimensional positions determined. The distances between the imaging devices and the subjects are determined and the distances between the imaging devices and the subjects are calculated. This provides the focus setting information for communication to the imaging devices. The tracking patterns may have no rotational symmetry, allowing the orientation of subjects to be determined.

主权项

1. A system for automatically adjusting a focus setting of at least one imaging device on an imaging set, the system comprising:
two or more tracking markers, each tracking marker comprising an identification means and a tracking pattern, the two or more tracking markers configured for attaching to the at least one imaging device and to corresponding one or more subjects to be imaged on the imaging set by the at least one imaging device; a first tracker disposed proximate the imaging set to gather first image information of the imaging set, the first tracker having a field of view including the at least one imaging device and the one or more subjects; a controller configured for receiving the first image information from the first tracker and for communicating to the at least one imaging device control signals for the adjusting of focus settings for the at least one imaging device based on distances between the at least one imaging device and the one or more subjects; and a database comprising predetermined information about the two or more identities and two or more tracking patterns of the corresponding two or more tracking markers.
