IMAGING DATA CORRECTION SYSTEM AND METHOD

摘要

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.

1. A method of correcting imaging data received from a sensor for environmental effects, the method comprising:
placing a calibration system a distance from an object that is in a monitored environment from which imaging data is to be collected by a sensor during a data collection time period, in an environment comparable to the monitored environment, the calibration system being configured to emit and/or radiate a test pattern having geometric, temporal, and/or electromagnetic characteristics, the calibration system having at least one emission/radiation point, each emission/radiation point including at least one emission/radiation source that emits and/or radiates in a region of the electromagnetic spectrum, the calibration system and the object being sufficiently far from the sensor so that imaging data collected by the sensor is distorted by atmospheric variables; emitting and/or radiating the test pattern having geometric, temporal, and/or electromagnetic characteristics with the calibration system; collecting imaging data from the calibration system with a sensor; comparing the imaging data collected by the sensor from the test pattern to the geometric, temporal, and/or electromagnetic characteristics of the test pattern to determine distortion caused by the atmospheric variables; 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/or electromagnetic characteristics of the test pattern; and correcting the imaging data collected by the sensor from the object during the data collection time period by the error factor to reduce the distortion caused by the atmospheric variables.
