Aerial 720-DEG photographing panoramic contrast method of unmanned aerial vehicle

Abstract

The invention relates to an aerial 720-DEG photographing panoramic contrast method of an unmanned aerial vehicle. The method comprises the following steps: acquiring two groups of unmanned aerial vehicle 720-DEG panoramic aerial images; respectively constructing two skyboxes by using each group of unmanned aerial vehicle 720-DEG panoramic aerial images by taking the camera as the center; monitoring visual angle parameters of two cameras, and constructing an interconnected controller to maintain the visual angle synchronization; respectively acquiring a half image from the respective skybox through the visual angle movement of each of two cameras; splicing the images acquired by two cameras to generate a contrast image. Through the aerial 720-DEG photographing panoramic contrast method of the unmanned aerial vehicle disclosed by the invention, the unmanned aerial vehicle panoramic aerial image contrast at different time or different locations can be realized.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a method for comparing 720-degree aerial panoramas of unmanned aerial vehicles in the air. Background technique [0002] Panoramic picture display is a unique image display method, the intelligent method for rapidly generating high-definition panoramas based on round fisheye or drum-shaped images disclosed by Chinese invention patent specification CN1707354A (public date: December 14, 2005), Chinese invention patent The method disclosed in the specification CN1707355A (published on December 14, 2005) based on six drum-shaped images to generate a full spherical panorama. Then there was a method of combining panoramic images with geographic information systems, and the Chinese invention patent specification (Chinese Patent No. ZL 200610026274.3, authorized announcement date May 20, 2009) disclosed the method of constructing panoramic electronic map services.

Problems solved by technology

[0003] The above technology is a good illustration of the evolution process of panoramic picture technology. From the display of panoramic pictures to panoramic electronic maps, the application of ordinary panoramic pictures has been solved, but it does not involve the comparison of panoramic images. For some application fields, such as infrastructure projects For the progress comparison of the main building, it is necessary to compare the panoramic images of the main building of the infrastructure project at different times, so as to clarify the completion progress and facilitate the progress control; for example, for water pollution control, it is necessary to compare the panoramic images of the same waterway at different times In order to find the pollution situation to facilitate governance; in addition, in some site selection issues, it is also necessary to compare the panoramic images of different places to determine the advantages and disadvantages for decision-making... In these fields that require the use of panoramic image comparisons, it is currently It is very troublesome to rely on manual comparison and analysis
