1. A system comprising:
- a vehicle having vehicle position sensors;
a first video camera mounted to said vehicle and having camera position sensors and producing a first video feed in a first camera field of view;
a field of view calculator adapted to;
use said vehicle position sensors and said camera position sensors to produce a first calculated field of view;
determine that a first landmark is approximately located within said first camera field of view;
determine a calculated position of said first landmark within said first camera field of view;
find the actual position of said landmark within said first video feed;
compare said calculated position and said actual position of said landmark to determine a set of correction factors; and
use said correction factors to change said first calculated field of view;
an indicia generator adapted to use said first calculated field of view to produce at least one indicator within said first camera field of view;
a video display adapted to display said first video feed and said indicator.

Abstract
A system and method for placing reference locators on a streaming video image taken from a camera mounted on a vehicle. Sensors monitoring the camera field of view and direction of the optical axis along with sensors monitoring the vehicle'"'"'s position are used to generate a video overlay having various indicia. The calculated positions of the indicia may be compared to the position of landmarks taken from the video image to compensate for any inaccuracies in the calculated position taken from the various sensors.
