Method, arrangement, and computer program product for coordinating video information with other measurements

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 a digital image of said target area,
• detecting the locations where the reference targets appear in said digital image,
• from the coordinates of said reference targets in said digital image and the measured coordinates of said reference targets at said reference locations, forming a mapping function that maps measured coordinates in said target plane into coordinates in said digital image,
• using said remote sensing apparatus to detect the appearance of objects that intersect said target plane and to output measured coordinates of detected objects,
• using said mapping function to convert said measured coordinates of said detected objects into coordinates in said digital image, and
• outputting and storing a combination image containing location-bound indications of detected objects with said digital image.

An arrangement for coordinating video information with other measurements, comprising:

• a coordinate input configured to provide coordinates of reference targets, measured with a remote sensing apparatus, at at least two reference locations in a target plane that is located within or adjacent to a target area, and configured to express said coordinates in a two-dimensional coordinate system that coincides with said target plane, wherein said coordinate input comprises a connection from one of a laser scanner and a three-dimensional reflection analyser,
• an image input configured to provide at least two at least partially non-overlapping digital images of said target area,
• an image processor configured to detect the locations where the reference targets appear in said digital images and to modify 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, and
• an image storage configured to store a combination image combined from the modified digital images,
• wherein the image processor is further configured to plot indications of detected objects that cut the target plane using said combination image as background.
