Abstract

The invention provides an unmanned aerial vehicle and a panoramic stitching method, device and system thereof. The method comprises the following steps of obtaining multiple frames of images for stitching; carrying out panoramic stitching on the multiple frames of images at an unmanned aerial vehicle side based on a preset rule to obtain a panoramic image; and sending the panoramic image to a mobile terminal. Since the multiple frames of images for stitching are obtained at the unmanned aerial vehicle side, and the panoramic stitching is carried out on the multiple frames of images based on the preset rule to obtain the panoramic image, image distortion caused by encoding and compression of the multiple frames of images for stitching is avoided, and stitching errors are reduced. Moreover, since the panoramic image is stitched at the unmanned aerial vehicle side, compared with the manner of stitching the panoramic image at the mobile terminal, the response time from obtaining the images to stitching the images is shortened, the stitching efficiency is improved, and the panoramic stitching instantaneity is improved.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle video image processing, in particular to an unmanned aerial vehicle and its panorama stitching method, device and system. Background technique [0002] The development of image stitching technology is becoming more and more mature. Image stitching technology refers to the technology of stitching several images (which may be images obtained at different times, different angles of view or different sensors) into a large seamless high-resolution image. Image stitching technology has been widely used in space exploration, remote sensing images, medical image analysis and other fields. With the continuous development of civilian aerial photography UAV technology, the application range of UAV is also expanding rapidly, and it has also been widely used in advertising photography, transportation, disaster detection and other fields. Combining image stitching technology with aerial photography drone...
