Abstract
A device for use in obtaining one or more calibration parameters of an array of two-dimensional sensors used in stereotactic localization of objects in a workspace. The device comprises a target array and a positioner capable of positioning the target array at a desired location in the workspace.
Claims26
A device for use in obtaining one or more calibration parameters of an array of two-dimensional sensors used in stereotactic localization of objects in a workspace, the device comprising:
- (a) a two-dimensional array of targets;
- and
- (b) a positioner capable of positioning the array at a plurality of desired locations in the workspace.
A method for obtaining one or more calibration parameters of an array of two-dimensional sensors used in stereotactic localization of objects in a workspace, each sensor in the sensor array viewing the workspace along a fixed sight line and producing a signal characteristic of its view of the workspace, the method comprising:
- (a) positioning a two-dimensional target array at each of a plurality of desired locations in the workspace;
- (b) for each of the desired locations, processing the signals produced by one or more sensors in the sensor array;
- and
- (c) calculating the one or more calibration parameters of the sensor array based upon the processed signals obtained on at least two positions.
