Title:
METHOD OF CALIBRATING STEREO CAMERA INSTALLATION PARAMETER
Document Type and Number:
WIPO Patent Application WO/2017/209015
Kind Code:
A1
Abstract:
A method of calibrating a stereo camera installation parameter according to a mode of embodiment of the present invention is a method of calibrating an installation parameter of a stereo camera which is attached to a movable object and captures images of a road surface over which the object is to move, in order to detect the height of the road surface. According to this method: the stereo camera captures an image of a road surface on which a mark has been provided a prescribed distance from the position of the stereo camera; the installation parameter and the value of the prescribed distance are used to obtain a vertical axis direction position in a coordinate space in the image captured by the stereo camera; and the obtained vertical axis direction position and the vertical axis direction position of the imaged mark in the coordinate space are compared, and the installation parameter is calibrated on the basis of the comparison result.
