1. A method of correcting imaging data received from a sensor for environmental effects, the method comprising:

  • placing a calibration system in an environment similar to or the same as a monitored 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 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 an object during the data collection time period by the error factor to reduce the distortion caused by the atmospheric variables.
