Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] (1) The flow chart of UAV telemetry data processing is as follows: figure 2 shown. On the GIS system, set the relevant parameters of the UAV aircraft, mainly including the current model, aircraft ID, network transmission address, port number and other parameters.

[0028] (2) After the parameter configuration is completed, you can start to receive real-time telemetry data, match the corresponding configuration file according to the aircraft model, and complete the interpretation, storage and forwarding of the telemetry data. The standard data format after interpretation is as follows:

[0029] {"PlaneData":[{"FlyingTime":"633.000000","PlaneID":"MD1000","head":"-28437.000000"}]}

[0030] {"PlaneData":[{"GPSPrecision":"-0.001600","GPSstar":"12.000000","Latitude":"19.469603","Longitude":"1 08.888290","PlaneID":"MD1000"," head":"-28437.000000"}]}...

Abstract

The invention relates to an unmanned aerial vehicle sea area monitoring method based on a GIS, and the method comprises the following steps: obtaining an unmanned aerial vehicle measurement and control related parameter field in the form of a configuration file on a GIS system; for a specific unmanned aerial vehicle, receiving real-time video data of the unmanned aerial vehicle and telemetry datagenerated and stored by a flight control system; for the video data, utilizing a method based on gray projection to realize rapid motion estimation of video frames to form video motion codes; for thetelemetry data, coding the unmanned aerial vehicle and the motion mode of the load by taking time as an axis according to the unmanned aerial vehicle load state data and the load state data analyzed by the telemetry data to obtain a telemetry motion code; and realizing the synchronization of telemetry data and video data.

Description

technical field [0001] The invention belongs to the field of sea area monitoring, and in particular relates to a GIS-based information visualization system. Background technique [0002] Geographic Information System (GIS, Geographic Information System) plays an important role in sea area monitoring and management, and the digitization and informatization of sea area network cannot be separated from the support of GIS technology. [0003] At present, in the UAV monitoring of sea areas, each marine functional department carries out the construction of marine UAV monitoring work independently. The differences in UAV platforms, payloads, and data processing systems and methods of various departments make data acquisition, data processing, data management and distribution and The difficulty of sharing has increased, and it is difficult to meet the current extensive sea area monitoring needs, which directly limits the construction and operation of the UAV sea area surveillance an...
