Embodiment 1
[0166] Embodiment 1: A method of calibrating a patient monitoring system for monitoring the positioning of a patient at first and second locations spaced apart by a fixed distance, the method comprising:
[0167] providing a monitoring system operable to obtain images of the patient proximate to the first and second locations;
[0168] providing a calibration object having a first set of calibration marks and a second set of calibration marks, the first set of calibration marks being offset from the second set of calibration marks by a distance corresponding to the distance between the first and second positions;
[0169] positioning the calibration object such that a first set of calibration marks is located adjacent a first location and a second set of calibration marks is located adjacent a second location;
[0170] obtaining images of the first and second sets of calibration marks using the monitoring system; and
[0171] The monitoring system is calibrated based on the a...
Embodiment 2
[0172] Embodiment 2: The method of Embodiment 1, wherein the monitoring system comprises a plurality of 3D cameras, wherein at least one 3D camera is configured to capture images of objects near the first location and at least one 3D camera is configured to capture images of objects near the second location Image.
Embodiment 3
[0173] Embodiment 3: The method according to embodiment 2, wherein the 3D camera comprises a 3D camera selected from the group consisting of: a stereo camera; a 3D time-of-flight camera and a 3D camera utilizing structured light to project onto the surface of the monitored object.
