Abstract

The embodiment of the invention discloses a three-dimensional digital sandbox deducing method and system based on augmented reality. The three-dimensional digital sandbox deducing method comprises thesteps that a display terminal receives a first operation of a user to open a sandbox deducing application program; in the sandbox deducing application program, the display terminal acquires a currentactual environment picture through a built-in image acquisition device; the display terminal conducts feature extraction on the current actual environment picture to obtain a target feature point; the display terminal conducts matching processing on the target feature point according to a preset database so as to obtain a target position; the display terminal obtains and displays a target virtualscene according to the target position; the display terminal receives second operations of a target virtual scene, wherein the second operations include movement, zooming, lifting, character behaviorsetting and real-time dynamic display and screen capture of a sandbox display effect or video generation. By adopting the three-dimensional digital sandbox deducing method and system, the immersion sense of a user watching an actual object is improved, and an interaction effect is improved.

Description

technical field

[0001] The invention relates to the field of augmented reality technology, in particular to a three-dimensional digital sand table deduction method based on augmented reality and a system thereof. Background technique

[0002] The sand table is a model made of sand, war chess and other materials according to the topographic map, aerial photo or field terrain, according to a certain proportion. The sand table is used to miniaturize the landform or buildings for people to observe, and has been widely used in military or commercial activities.

[0003] However, the known sand tables are mainly solid plane sand tables, and most of them use models to perform static representations of themes such as buildings. The display effect is not interesting, and it also lacks interactivity for the audience. For this reason, a kind of interactive multimedia sand table has appeared, and its main scheme is as follows: On the basis of the traditional sand table model, it is org...
