Embodiment Construction

[0028] The invention provides a method for processing video data of a UAV. The data downloaded by the UAV includes video data and telemetry data, and the telemetry data includes UAV attitude data and load attitude data, such as figure 1 As shown, the steps of the UAV video data processing method of the present invention are as follows:

[0029] (1) Decompress the video data downloaded by the drone to obtain image data, and extract feature points from each frame of image data; digital images use a series of numbers to represent the depth of each pixel on the image. The difference in brightness and texture in the image is represented by different digital values. The places where the pixel values ​​change sharply appear as edges or corners on the image; these image features are determined by the geometric or color properties of the target itself. Therefore, the performance of the same target in several adjacent video images is similar, but the geometric deformation of the target...

Abstract

The invention relates to an unmanned aerial vehicle video data processing method, in particular relates to a method for matching and fusing respective processing results after respective processing on unmanned aerial vehicle video data and remote measuring data. The method disclosed by the invention can solve the problem of synchronization between ground video data and the remote measuring data on an unmanned aerial vehicle, especially a microminiature unmanned aerial vehicle platform, and matching correlation processing is carried out for improving the synchronization accuracy and observation accuracy of the video data and the remote measuring data; and post processing error caused by non synchronization of the video data and the remote measuring data is effectively improved by adopting the method disclosed by the invention.

Description

technical field [0001] The invention relates to a method for processing video data of an unmanned aerial vehicle, which can be used for an unmanned aerial vehicle, especially a micro-miniature unmanned aerial vehicle platform, and is used to improve the synchronization accuracy and data processing accuracy of the unmanned aerial vehicle video data and telemetry data. Background technique [0002] At present, UAV platforms are used as aerial platforms for reconnaissance and strikes. Its data processing and related decisions are made by ground operators. The main thing to deal with is the specific location of the UAV's reconnaissance target and strike target, which may be the geographic location or relative position relative to the strike firepower; this requires the use of data processing algorithms to obtain the location information of the UAV's reconnaissance target. The accuracy of the target position obtained through the processing algorithm determines the effect of reco...
