Embodiment Construction

[0042] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0043] This implementation example is realized through the following technical solutions, such as figure 1 As shown, a real-time video stitching method based on multiple UAVs includes: 1. UAV posture correction, 2. Image shooting, 3. Image processing and feature extraction, 4. The ground station receives processed image information, 5. Feature matching area search, 6, outlier removal, 7, video splicing quality optimization, 8, spliced ​​video output. Among them, UAV posture correction uses the mutual mapping relationship between the image pixel coordinate system and the global coordinate system, and adjusts in the global coordinate system; image processing and feature extraction are carried out by the UAV onboard CPU; feature matching area search uses the pixel coordinate system and The corresponding relationship of the global coordinate system is car...

Abstract

The invention discloses a real-time video splicing method based on multiple unmanned aerial vehicles. The method comprises the following steps: step 1, correcting postures of the unmanned aerial vehicles; performing adjusting in the global coordinate system by using the mutual mapping relation of the image pixel coordinate system and the global coordinate system; step 2, carrying out image shooting; step 3, carrying ot image processing and feature extraction; carrying out image processing and feature extraction by utilizing an unmanned aerial vehicle airborne CPU; 4, enabling the ground station to receive the processed image information; 5, searching a feature matching area; step 6, deleting abnormal values; deleting the abnormal value by adopting an improved random sampling consistency algorithm; step 7, optimizing video splicing quality; and step 8, splicing video output. According to the invention, the workload of a ground station is reduced by adopting a distributed feature extraction technology, the splicing efficiency is improved by utilizing the prompt of a flight controller, the splicing speed of images shot by a plurality of unmanned aerial vehicles is improved, the splicing quality is improved, and the real-time splicing output of the images shot by the plurality of unmanned aerial vehicles is realized.

Description

technical field [0001] The invention belongs to video splicing technology, in particular to a real-time video splicing method based on multiple drones. Background technique [0002] The proliferation of commercial drone technology has enabled the deployment of aerial video surveillance systems to achieve unprecedented perspectives when monitoring target areas from the air; drone-based surveillance systems have a wide range of applications, including firefighting, search and rescue, and border surveillance. [0003] For example, a drone could be deployed to hover over a bushfire, streaming live video via a wireless connection to firefighters, allowing them to assess the situation from an aerial perspective. However, due to the limited field of view of the airborne camera, multiple UAVs are required to simultaneously cover a large target area for shooting; however, the video information captured by multiple UAVs is separated, and the ground receiving station receives the relev...
