Unmanned plane video image target positioning system and method and holder control method

Abstract

The invention discloses an unmanned plane video image target positioning system and method based on metadata and a holder control method and solves a problem that the position of a shot target of a video can not be acquired and displayed in the prior art. In combination with the target area position and the position and flight parameters of an unmanned plane, holder orientation and a pitch angle parameter are solved in real time, the target in the video is positioned, the target is assigned through frame selection of the video returned by the unmanned plane in an unmanned plane flight process, target positioning is supported, and the target area acquired through frame selection is displayed in a GIS map in real time. The method is advantaged in that a problem of inconvenience in manually adjusting a holder in the prior art is solved, point clicking on the GIS map to assign the target is supported, according to the unmanned plane, the target position, the flight parameter and the elevation data information, holder parameters are solved, the holder is controlled for rotation, and the target is made to be at a sensor vision axis center.

Description

technical field [0001] The invention belongs to the field of UAV target positioning and video image processing, and in particular relates to a metadata-based UAV video image target positioning system, a positioning method and a UAV cloud platform control method. Background technique [0002] UAV (Unmanned Aerial Vehicle, UAV), as a new type of modern military equipment, with its unique "unmanned" advantage, fully conforms to the modern warfare concept of "no meeting" and "zero casualties". By carrying different equipment, drones can perform tasks such as reconnaissance and surveillance, laser guidance, electronic jamming, communication relay, target positioning, combat assessment, and precision strikes. UAVs are also promising for civilian use. They can be used in field monitoring, weather detection, highway inspection, surveying and mapping, flood monitoring, aerial photography, traffic management, power line inquiries, forest fire prevention and rescue, etc. [0003] In r...

Problems solved by technology

[0007] Existing UAV operating systems, such as DJI, usually can only display the position coordinates of the UAV itself and the general orientation of the gimbal on the map during the flight of the UAV, and cannot obtain and display the information in the video. The location of the captured target; on the other hand, when the target in the designated area needs to be reconnaissance, the existing UAV operating system needs to manually adjust the pan / tilt, and can only rely on the real-time returned video to manually judge the pan / tilt control direction, operation is extremely inconvenient
