Abstract
Methods and apparatus are provided for determining a trailer dimension including a radar for generating a depth map wherein the depth map includes a detection of a first trailer surface, a camera for generating an image of the first trailer surface, a processor operative to determine a first dimension of the first trailer surface in response to the depth map and a second dimension of the first trailer surface in response to the first dimension and the image, and a vehicle controller controlling a vehicle in response to the first dimension and the second dimension.
Claims20
An apparatus comprising:
- a radar for generating a depth map wherein the depth map includes a detection of a first trailer surface;
- a camera for generating an image of the first trailer surface;
- a processor operative to determine a first horizontal dimension of the first trailer surface in response to the depth map and a vertical dimension of the first trailer surface in response to the first horizontal dimension and the image;
- and
- a vehicle controller controlling a vehicle in response to the first horizontal dimension and the vertical dimension.
A method comprising:
- capturing, by a radar, a radar map wherein the radar map is indicative of a location of a first trailer surface;
- capturing, by a camera, an image wherein the image includes the first trailer surface;
- estimating, using a processor, a first horizontal dimension of the first trailer surface in response to the radar map;
- estimating, using the processor, a vertical dimension of the first trailer surface in response to the first horizontal dimension and the image;
- transmitting the first horizontal dimension and the vertical dimension to a vehicle controller;
- controlling, using the vehicle controller, a vehicle performing a trailering operation in response to the first horizontal dimension and the vertical dimension.
An advanced driver assistance system comprising;
- a radar for generating a depth map wherein the depth map is indicative of a first surface of a trailer and a second surface of the trailer;
- a camera for capturing an image of the first surface;
- a processor configured to determine a width of the trailer and a length of the trailer in response to the depth map indicative of the first surface and the depth map indicative of the second surface, the processor being further operative to determine a height of the trailer in response to the width of the trailer and the image;
- and
- a vehicle controller configured to perform an assisted driving operation in response to the width, the length and the height of the trailer.
