1. A system for determining a distance to a region of interest comprising: a first camera configured to have a first field of view; a second camera configured to have a second field of view that overlaps at least a portion of the first field of view; a control device configured to allow a user to select a region of interest in the at least a portion of the first field of view that overlaps the second field of view; a processor configured to calculate a distance of the selected region of interest relative to a location by comparing a position of the selected region of interest in the first field of view with a position of the selected region of interest in the second field of view; and a display device configured to produce a display of the distance calculated by the processor, wherein the first field of view includes a horizontal dimension and a vertical dimension, and the second field of view includes a horizontal dimension and a vertical dimension; and wherein the processor is further configured to calculate the distance of the selected region of interest relative to the location by comparing the position of the selected region of interest in the horizontal dimension of the first field of view with the position of the selected region of interest in the horizontal dimension of the second field of view.
