METHOD AND SYSTEM FOR RECALIBRATING SENSING DEVICES WITHOUT FAMILIAR TARGETS
First Claim
1. A method comprising:
- capturing a scene using a sensing device;
determining whether or not the device is calibrated;
in a case that said sensing device is calibrated, adding at least one new landmark to the known landmarks;
in a case that said sensing device is not calibrated, determining at least some of the captured objects as objects stored on a database as known landmarks at the scene whose position is known; and
calibrating the sensing device based on the known landmarks.

Abstract
Methods and systems for recalibrating sensing devices without using familiar targets are provided herein. The method may include: capturing a scene using a sensing device; determining whether or not the device is calibrated; in a case that said sensing device is calibrated, adding at least one new landmark to the known landmarks; in a case that said sensing device is not calibrated, determining at least some of the captured objects as objects stored on a database as known landmarks at the scene whose position is known; and calibrating the sensing device based on the known landmarks. The system may have various architectures that include a sensing device which captures images of the scene and further derive 3D data on the scene of some form.

13. A method comprising:
-
capturing a scene using a sensing device; determining whether the captured scene contains a minimal number of known landmarks sufficient for determining whether the sensing device is calibrated; in a case that the captured scene contains said minimal number of landmarks, checking whether said sensing device is calibrated, in a case that said sensing device is calibrated, adding at least one new landmark to the known landmarks; in a case that said sensing device is not calibrated, calibrating the sensing device based on the known landmarks; and in a case that the captured scene does not contain said minimal number of landmarks, checking calibration of the sensing device without using known landmarks, and in a case that the sensing device is calibrated, adding at least one new landmark to the known landmarks. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
