First Claim
Patent Images
1. A method for recognizing a position of an obstacle in a vehicle, comprising:
- obtaining image data and ultrasonic sensor data through a camera and an ultrasonic sensor, respectively;
detecting edges of the obstacle perpendicular to a ground surface in the image data;
detecting a discontinuous position at which the ultrasonic sensor data are not continuous;
detecting intersection points of a straight line connecting edges of the obstacle detected in continuous images from the image data to a center position of the camera when the discontinuous position coincides with a camera position; and
estimating the intersection points to be the position of the obstacle.

Abstract
An apparatus for recognizing a position of an obstacle in a vehicle obtains image data and ultrasonic sensor data through a camera and an ultrasonic sensor, detects linear edges perpendicular to a ground surface in the image data, detects a discontinuous position at which the ultrasonic sensor data are not continuous, detects intersection points of the linear edges detected in continuous images from the image data when the discontinuous position coincides with a camera position, and estimates the intersection points to be the position of the obstacle.

10. An apparatus for recognizing a position of an obstacle in a vehicle, comprising:
-
a camera configured to photograph image data around the vehicle; an ultrasonic sensor configured to sense an obstacle around the vehicle; and a controller configured to detect edges of the obstacle perpendicular to a ground surface in the image data to register the edges of the obstacle in a storage based on movement information of the vehicle, detect a discontinuous position of ultrasonic sensor data output from the ultrasonic sensor, and detect intersection points of a straight line connecting the edges detected in continuous image data obtained within a predetermined distance based on a camera position to a center position of the camera when the discontinuous position coincides with the camera position to recognize the intersection points of the straight line connecting the edges to the center position of the camera to be positions of edges of the obstacle. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
