Abstract : This technical report summarizes the intrinsic sensor parameters for the range IR and color sensor used in the Fort Carson data collection and explores sensor-to-sensor image mapping under different assumptions regarding relative sensor placement. The default case is to assume perfectly boresight aligned placement, and then the implications of different deviations from this perfect placement are considered. Included in this report is a description of the calibration process used to recover the color sensor parameters. A key result shown in detail is the relative equivalence of planar sensor translation and small angle pan and tilt for points of known depth. This simplifying approximation has significant implications when fusing data from separate range and optical sensors.
