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.
