IMAGING DATA CORRECTION SYSTEM AND METHOD
First Claim
Patent Images
1. A method of correcting imaging data received from a sensor for environmental effects, the method comprising:
- placing a calibration system into an environment comparable to an environment from which imaging data is to be collected by a sensor during a data collection time period, the calibration system being configured to emit a test pattern having geometric, temporal, and electromagnetic characteristics, the calibration system having at least one emission point, each emission point including at least one emission source that emits in a region of the electromagnetic spectrum;
emitting the test pattern having geometric, temporal, and electromagnetic characteristics with the calibration system during the data collection time period;
collecting imaging data from the calibration system with a sensor during the data collection time period;
comparing the imaging data collected by the sensor from the test pattern to the geometric, temporal, and electromagnetic characteristics of the test pattern;
determining an imaging error factor based on differences between the imaging data collected by the sensor from the test pattern and the geometric, temporal, and electromagnetic characteristics of the test pattern; and
correcting the imaging data by the error factor.

Abstract
Methods and systems for use in calibrating imaging data, are provided that include using a calibration array to generate a test pattern. The calibration array can emit a test pattern having geometric, temporal, and electromagnetic characteristics. The collected data can be compared with the geometric, temporal and electromagnetic characteristics to determine an error factor that can then be used in analyzing the collected data.

13. A calibration system that can be placed into an environment comparable to an environment from which imaging data is to be collected by a sensor and used for correcting imaging data received from the sensor, the calibration system comprising:
-
a calibration array that emits a test pattern having geometric, temporal, and electromagnetic characteristics, the calibration array having a plurality of emission points, each emission point including at least one emission source that emits in a region of the electromagnetic spectrum; a control unit operatively connected to the calibration array that provides test pattern commands to the calibration array in order to cause the calibration array to emit the test pattern; and a communication system operatively connected to the control unit that communicates data from the calibration system to a remote location. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 28, 29, 31)
