Problems solved by technology

The existing UAV real-time stitching method relies on the UAV-side processor to perform panorama stitching calculations. The existing UAV-side embedded processor has average computing power and encounters a lot of complicated image data. The processing of the UAV-side The server cannot handle it, which will cause poor user experience
The other is the post-processing panoramic stitching method, which copies the images collected by the drone to the local computer for stitching. This panoramic stitching method completely loses the real-time advantage of the drone, and the user experience is poor.

Abstract

The invention discloses a panoramic stitching method based on unmanned aerial vehicle cloud server calculation. The panoramic stitching method comprises the steps that S100, a mobile terminal sends apanoramic stitching instruction to an unmanned aerial vehicle in a wireless transmission mode; s200, the unmanned aerial vehicle receives the panoramic stitching instruction, and obtains a to-be-stitched image through a pan-tilt camera of the unmanned aerial vehicle; s300, the unmanned aerial vehicle sends the acquired images to be spliced to a cloud server through wireless transmission; s400, thecloud server receives the image sent by the unmanned aerial vehicle, and calculates a panoramic image through a panoramic stitching algorithm; s500, the cloud server transmits the panoramic image toa mobile terminal in a wireless transmission mode; and S600, the mobile terminal displays the received panoramic image spliced by the unmanned aerial vehicle to a user. The cloud server is used for splicing a large amount of image data, the problem that the task of image splicing cannot be completed due to insufficient calculation power of the unmanned aerial vehicle end is solved, the calculationpower of the unmanned aerial vehicle processor is improved, and the calculation performance of the unmanned aerial vehicle is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method and system for panorama stitching based on UAV cloud server computing. Background technique [0002] In recent years, with the development of UAV image panorama stitching technology, more and more UAVs have been used as important tools in various industries, such as: tourism aerial photography, TV series and movie materials, fire disaster relief, traffic sorting, surveying and mapping Mapping, agricultural plant monitoring, etc. At present, the images acquired by drones in the sky are stitched together, and the staff on the ground can extract a lot of useful information through the stitched panoramic images. For example, when firefighters face a forest fire, they use drones to capture and splicing images in the air, and give firefighting commanders an accurate fire area and fire trend information in a timely manner to help them quickly make decisions on ...
