Problems solved by technology

Therefore, this remote sensing quantitative analysis method has the problem of high cost
Non-professional-level drones are equipped with ordinary cameras, so the images taken by non-professional-level cameras only carry the RGB information of the subject. This information is only suitable for general viewing and cannot be applied to the field of quantitative analysis. Image data is of low value

Abstract

The embodiment of the invention discloses an automatic registration method and device for the unmanned aerial vehicle images and an electronic device. The method comprises the following steps of obtaining a to-be-processed image collected by an unmanned aerial vehicle, determining the unmanned aerial vehicle flight attitude information corresponding to the to-be-processed image, the shooting parameters of an unmanned aerial vehicle camera, the corresponding geographic coordinates during imaging of the unmanned aerial vehicle camera and the corresponding height parameters, wherein the flight attitude information of the unmanned aerial vehicle at least comprises a course angle, a pitch angle and a roll angle, and the shooting parameter information at least comprises an image size and a fieldangle of the unmanned aerial vehicle camera, based on the pitch angle and the roll angle, determining the imaging direction of the unmanned aerial vehicle camera, and if the imaging direction of theunmanned aerial vehicle camera is perpendicular to the ground, determining the geographic coordinates corresponding to each pixel on the to-be-processed image based on a pre-configured calculation model according to the course angle and the camera shooting parameters. According to the method, the geographic coordinates of the pixels of the image are calculated, and the common images are convertedinto the remote sensing images, so that the purpose of improving the unmanned aerial vehicle image data value is achieved.

Description

technical field [0001] The present application relates to the technical field of image registration, and in particular, the present application relates to an automatic registration method, device and electronic equipment for drone images. Background technique [0002] At present, with the development of UAV technology, UAV remote sensing observation is widely used. Existing drones include professional-grade drones and non-professional-grade drones. Existing remote sensing observations mainly use professional UAVs for image collection. Due to the geographic projection information and spectral radiation information of professional UAVs, the images taken by professional UAVs can be directly applied to Quantitative analysis of remote sensing. Therefore, this remote sensing quantitative analysis method has the problem of high cost. Non-professional-level drones are equipped with ordinary cameras, so the images taken by non-professional-level cameras only carry the RGB informat...
