Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] Such as figure 1 As shown, the GIS-based panorama scene automatic association method includes the following steps:

[0017] Step S1: Use the UAV to shoot in the air; turn on the UAV and the control platform, and when the GPS signal is good, let the UAV fly at a fixed height above the landscape, and adjust the initial shooting angle on the operating platform so that no The initial orientation of the man-machine is geographically true north, and then it is rotated to take pictures. The photos taken have GPS attributes of latitude and longitude, altitude and angle with true north;

[0018] Step S2: Synthesize a group of photos of a scene so that the center of the synthesized panorama is in the direction of head-on and true north, check the exif information of the synthesized panorama photos, and confirm that each panorama photo has GPS at...

Abstract

The invention discloses a GIS-based panorama scene automatic association method. The method includes the steps of firstly, using a drone in the air to shoot landscape; secondly, synthesizing landscapeimages; thirdly, writing the name, longitude and latitude, altitude and due-north included angle data of each scene image into List<E> objects; fourthly, performing GIS distance calculation on the longitude and latitude of two scenes, and associating the two scenes if the distance is smaller than or equal to a set scene association distance limit value; fifthly, performing relative horizontal angle calculation on every two corresponding associated scenes; sixthly, performing relative elevation angle calculation on every two corresponding associated scenes; seventhly, saving the horizontal angle and elevation angle of the associated scene of each scene as json data. The GIS-based panorama scene automatic association method has the advantages that a GIS algorithm is used to calculate the relative orientation and relative elevation angle of every two scenes, every two scenes are associated, automatic scene connection is achieved, manual matching cost is reduced, and error rate is lowered.

Description

technical field [0001] The invention relates to the technical field of three-dimensional real scene display, in particular to a method for automatically associating panorama scenes based on GIS. Background technique [0002] In the existing non-street-view 3D real-scene applications, the interconnection between scenes is done manually in each scene by adding scene hotspots associated with the scene and setting the direction and position, and then exporting relevant configuration data. In large-scale 3D real scene applications, when the number of scenes reaches a certain level, labor costs and error rates will inevitably increase. Contents of the invention [0003] In order to solve the problems in the above-mentioned prior art, the present invention proposes a method for automatically associating panorama scenes based on GIS, comprising the following steps: [0004] Step S1: Use the UAV to shoot in the air; turn on the UAV and the control platform, and when the GPS signal...
