Title:
METHOD AND DEVICE FOR CALIBRATING PITCH OF CAMERA ON VEHICLE AND METHOD AND DEVICE FOR CONTINUAL LEARNING OF VANISHING POINT ESTIMATION MODEL TO BE USED FOR CALIBRATING THE PITCH
Document Type and Number:
WIPO Patent Application WO/2021/215672
Kind Code:
A1
Abstract:
A method for calibrating a pitch of a camera on a vehicle is provided. The method includes steps of: a calibration device (a) inputting driving images from the camera into an object detection network to detect objects and generate object detection information and into a lane detection network to detect lanes and generate lane detection information; (b) profiling the object and the lane detection information to generate object profiling information and lane profiling information, inputting the object profiling information into an object-based pitch estimation module to select a first target object and a second target object to generate a first pitch and a second pitch, and (iii) inputting vanishing point detection information and the lane profiling information into a lane-based pitch estimation module to generate a third pitch and a fourth pitch; and (c) inputting the first to the fourth pitches into a pitch-deciding module to generate a decided pitch.
