Embodiment 1

[0035] Such as figure 1 A virtual interactive display system for agricultural products shown mainly includes an interactive module, a collection module, an identification module, a database module, a drawing module, and a display terminal;

[0036] The interactive module is for visitors to select the types of agricultural products and display content types;

[0037] The acquisition module collects the selection information of the interaction module and sends it to the identification module; in this embodiment, the acquisition module mainly includes a video camera, and the video camera tracks and shoots the selected image of the interaction module and sends it to the identification module;

[0038] The identification module identifies the selection information and feeds it back to the drawing module;

[0039] The database module stores digital media files of all types of display contents of all agricultural products;

[0040] The drawing module selects display content from th...

Embodiment 2

[0046] A method for virtual interactive display of agricultural products realized in combination with the above system, the flow chart of which is as follows figure 2 As shown in , it mainly includes the following steps:

[0047] S1. Utilize the video camera to take the front image of the calibration plate, calculate the two-dimensional coordinates of the four vertices of the largest circumscribed quadrilateral of the four divided regions in the image respectively from the digital images taken, and calculate the four largest circumscribed quadrilaterals of each region The two-dimensional coordinates of the vertices are saved in the identification module of the computer; at the same time, the marking patterns on the cards of all agricultural products are scanned into digital images, and saved in the identification module of the computer, and the name of the agricultural product corresponding to each marking pattern is recorded at the same time.

[0048]S2. The acquisition modu...

Abstract

The invention relates to the technical field of virtual reality, in particular to a virtual interaction display system and a virtual interaction display method for agricultural products based on an augmented-reality technology. An interaction module is used by a visitor for selecting an agricultural product type and a display content type; an acquisition module is for acquiring selection information of the interaction module; an identification module is used for identifying the selection information; and a drawing module is used for selecting display contents from a database module according to an identification result fed back by the identification module and displaying on a display terminal. Due to the adoption of the virtual interaction display system and the virtual interaction display method, the application requirements of introduction, promotion, popular science education and the like on specific agricultural products can be met, and the field display interest and appeal of the agricultural products are enhanced; and meanwhile, the virtual interaction display system and the virtual interaction display method have the characteristics of easiness, practicability and capability of flexibly expanding display contents.

Description

technical field [0001] The invention relates to the field of virtual reality technology, in particular to a system and method for virtual interactive display of agricultural products based on augmented reality technology. Background technique [0002] At present, most interactive display systems for agricultural products mainly use graphics and image technology to make information such as the appearance, production process, and use of agricultural products into digital images, videos, or animations that can be played on computers, tablet computers, etc. The terminal is for users to play on-site, or for users to play remotely through the Internet, wireless network and other means. [0003] The wide application of information technology has greatly broadened the means of displaying agricultural products through paper publicity materials and on-site physical demonstrations, and improved the display effect and efficiency of agricultural products, which has positive practical sig...
