摘要：Embodiments of application discloses a method and device for determiningexternal parameters of a stereo camera. The method comprises: acquiring ground

surface data of a location of the stereo camera; generating, according to three-dimensional coordinates of each pixel in the ground surface data in a camera coordinatesystem corresponding to the stereo camera, a first plane equation in the cameracoordinate system that conforms to the three-dimensional coordinates of the pixels;determining, according to a distance between the origin of the camera coordinate systemand the ground surface, a setting height of the stereo camera; and generating, accordingto the first plane equation, a plane normal vector corresponding to the first planeequation; and determining, according to the plane normal vector, a pitch angle of thestereo camera and an inclination angle of the stereo camera. The external parameters ofthe stereo camera can be determined without using a reference point in a scene.
