Abstract
A device for measuring a parking space as a vehicle drives past the parking space includes a depth-measuring line scan camera movable together with the vehicle for acquiring individual images of the environment surrounding the vehicle transverse to a longitudinal direction of the vehicle, an arrangement for acquiring the movement of the vehicle, and an evaluation device. The individual images of the environment surrounding the vehicle contain depth information that is resolvable in a vertical direction.
Claims9
A device for measuring a parking space as a vehicle drives by the parking space, comprising:
- at least one sensor located on the vehicle and movable with the vehicle for acquiring data concerning the environment surrounding the vehicle in a horizontal direction transverse to a longitudinal direction of the vehicle, wherein the at least one sensor is a depth-measuring line scan camera, wherein the acquired data concerning the environment surrounding the vehicle are configured to be one-dimensionally resolved in an additional direction transverse to a longitudinal direction of the vehicle, and wherein the data concerning the environment surrounding the vehicle contain brightness information and depth information resolvable in the additional direction;
- an arrangement configured to acquire data regarding movement of the vehicle as the vehicle drives past the parking space;
- and
- at least one evaluation device configured to evaluate the data.
A method for measuring a parking space as a vehicle drives past the parking space, comprising:
- using a depth-measuring line scan camera, taking a sequence of individual images of a surrounding environment of the vehicle in a horizontal direction transverse to a longitudinal direction of the vehicle as the vehicle drives past the parking space, the individual images being resolved in an additional direction transverse to the longitudinal direction of the vehicle, wherein the individual images in the additional direction contain one-dimensionally resolved brightness and depth information;
- acquiring data regarding movement of the vehicle as the vehicle drives past the parking space;
- calculating a path increment from one individual photograph to a successive individual photograph;
- and
- determining, from the sequence of individual images with one-dimensionally resolved depth information, the boundaries of the parking space and the usable dimensions of the parking space.
