Abstract

An apparatus and method for determining the distinct location of an image-recording camera within an environment, using visually detectable structures includes the image-recording camera, a measuring camera permanently mounted thereon, and an evaluation unit configured to ascertain the distinct location of the image-recording camera from the measuring camera image structures. The two cameras are oriented to record a common detail from the environment, containing structures that are visually detectable by the two cameras in their images. The measuring camera is connected to the evaluation unit, which is designed to ascertain the distinct location of the image-recording camera from the environment structures detected by the measuring camera. The evaluation unit is configured to locate these structures in the image-recording camera image and to correct the location of the image-recording camera, ascertained from the measuring camera image, using the position of the structures from the image-recording camera image.
