The method comprises an action of processing the at least one digital image to calculate image positions of the depicted at least three light sources in each image. The method comprises an action of identifying the at least three light sources in each image by comparing a parameter computed from the at least one image and a respective parameter computed from a database. The method comprises an action of determining a position of the at least one sensor based on the identified at least three light sources.
