Title:

STEREOSCOPIC CAMERA AND HEIGHT ACQUISITION METHOD THEREFOR AND HEIGHT ACQUISITION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2018/153313

Kind Code:

A1

Abstract:

The present application relates to a stereoscopic camera, a height acquisition method therefor and a height acquisition system, which relate to the field of electronic technology applications. The method comprises: acquiring angle information of a stereoscopic camera, said angle information comprising a pitch angle and a tilt angle; capturing a ground image of a scene in which the stereoscopic camera is located; determining depth information of each pixel point on the ground image; creating a three-dimensional point set according to the depth information of each pixel point on the ground image, wherein said three-dimensional point set records coordinate information of a three-dimensional point corresponding to each pixel point on the ground image; according to the angle information and the three-dimensional point set, determining the height of the stereoscopic camera. The present application solves the problems wherein an operation process is complex when determining height by means of configuring an external reference structure and wherein the costs of determining height are high. The present application is used for determining the height of stereoscopic cameras.
