1. A method for coordinating video information with other measurements, comprising: measuring, with a remote sensing apparatus, coordinates of reference targets at at least two reference locations in a target plane that is located within or adjacent to a target area, wherein said remote sensing apparatus comprises one of a laser scanner and a three-dimensional reflection analyser, expressing said coordinates in a two-dimensional coordinate system that coincides with said target plane, providing at least two at least partially non-overlapping digital images of said target area, detecting the locations where the reference targets appear in said digital images, modifying said digital images to make the coordinates of said reference targets in said digital images coincide with the measured coordinates of said reference targets at said reference locations, outputting and storing a combination image combined from the modified digital images, and plotting indications of detected objects that cut the target plane using said combination image as background.
