Abstract
A parking assistance system is mounted in a vehicle, and has an image pick-up with a single camera, an image processing device, a display, a steering angle sensor, a wheel speed sensor, and a pulse counter. An A/D converter subjects two analog images picked up by the image pick-up at different locations to A/D conversion, and sends the results to frame memories. A CPU uses the digital image data and the transition data of the vehicle to calculate object data and a distance from the vehicle to the 3D object. An image thus obtained is then converted into a view from the above. The view from the above is stored in a frame memory, and outputted to the display under the control of a controller for display.
Claims17
A parking assistance system for assisting a driver of a vehicle to park by picking up an image around the vehicle, and advising the driver of what 3D object is located therearound, said parking assistance system comprising:
- an image pick-up having a single camera, said image pick-up being operable to pick up, during a transition of the vehicle, a first image and a second image around the vehicle at a first location and time and a second location and time, respectively;
- an object specification part being operable to detect and specify the 3D object found in each of the first image and the second image;
- a vehicle position calculation part being operable to calculate transition data of the vehicle from the first location to the second location;
- an object distance calculation part being operable to calculate a distance from the vehicle to the 3D object by using a position of the 3D object in each of the first image and the second image, and the transition data of the vehicle;
- and
- an image creation part being operable to create a third image for display to the driver based on the first image and the second image picked up by said image pick-up and data calculated by said object distance calculation part.
