Three-dimensional digital sand table engine technology and device based on aerial photography of unmanned aerial vehicle

Abstract

The invention discloses a three-dimensional digital sand table engine technology and device based on aerial photography of an unmanned aerial vehicle, and belongs to the technical field of digital sand tables. According to the present invention, the air routes can be planned according to a sand table area actual map, and the unmanned aerial vehicle can carry out the aerial survey automatically tocollect the data according to the air routes. The method comprises the steps of shooting pictures at multiple angles and at the shooting points; recording the photo data information of each shooting point and the corresponding geographic coordinate data; processing the geographic coordinate data acquired by the unmanned aerial vehicle; utilizing a model generation software, calculating and processing the aerial triangulation data by using a data cluster; carrying out model production, generating a three-dimensional data sand table model automatically; carrying out model refinement processing on the three-dimensional digital sand table, and carrying out ground object editing monomer restoration processing and texture mapping, displaying and presenting the generated three-dimensional digitalsand table data on the basis of a sand table engine which is independently researched and developed, and introducing an advanced interaction finger sleeve to achieve the diversified interaction withthe three-dimensional digital sand table, so that the display effect of the sand table is greatly improved.

Description

technical field [0001] The present invention relates to the technical field of digital sand table, and more specifically, relates to a three-dimensional digital sand table engine technology and device based on drone aerial photography. Background technique [0002] The digital sand table is mainly divided into two types: one is to add a multimedia projector system to the original traditional sand table model; the other is a pure three-dimensional digital sand table, which generally has an interactive function. The projection surface is generally a specially processed white or gray screen, with Solid sand table model. Through sound, light, electricity, image, three-dimensional animation and computer program control technology, it is integrated with the physical model. [0003] The digital sand table is realized through sound, light, electricity, image, three-dimensional animation and computer program control technology, and the use of digital projection. The digital sand tab...
