example 1

[0092] Example 1--Single-person gesture control real estate sand table display system

[0093] The main hardware list of the system is shown in Table 1, and the hardware structure is shown in the figure.

[0094] Table 1 Main hardware list of single-person gesture control real estate sand table display system

[0095]

[0096]

[0097] When the system starts, the system central control first reads the system running configuration from the server, and then calls the monocular camera to take pictures of real estate sand table images, and performs physical sand table calibration. After the calibration is completed, the graphical interface is initialized and displayed on a translucent display.

[0098] Deepin camera 2 captures user images in real time, and transmits the images to the central control of the system for face detection and calculation of the perspective angle of the graphical interface. Depth camera 1 captures the user's gestures in real time, conducts prelimin...

example 2

[0103] Example 2 - multi-person gesture control real estate sand table display system

[0104] This embodiment is a real estate sand table display system that supports multi-person gesture control. The hardware used in the system central control and data management background is the same as the previous example. The hardware list of the sand table booth is shown in Table 2, and the top view of the hardware structure is shown in the figure.

[0106]

[0107]

[0108] The system workflow is basically the same as Example 1, the difference is that the system no longer has the face capture function, and the graphical interface adopts a fixed layout. A touch film is pasted on the translucent display, which forms a touch area with the adjacent electric field sensor. When in use, the system detects the approach of the user through the electric field sensor, activate...

Abstract

The invention provides a sand table display system based on gesture control. The system comprises a system central controller, a sand table exhibition stand and a data management background, the system central controller is a control core of the system, controls the sand table exhibition stand and the data management background to operate normally, and calls corresponding functions according to application requirements and user instructions. The sand table exhibition stand comprises an entity sand table, a display terminal and a gesture interaction terminal. And the data management backgroundis used for storing and maintaining display content related data, providing support for the sand table exhibition stand and supporting other clients accessing the system to carry out data query. The system can be used for content display with a sand table as a core, has gesture interaction and data visualization functions, and supports data processing and maintenance related to the content. The system provided by the invention has both good impression experience of an entity sand table and rich data support of a virtual sand table. The display effect is good, the interaction experience is good, and use and maintenance are convenient.

Description

technical field [0001] The invention belongs to the technical field of gesture control, in particular to a sand table display system based on gesture control. Background technique [0002] The sand table is a miniature model made according to the regional topography, which is widely used in conference communication, commercial display, simulation and other fields. At present, the sand table includes two types: physical type and virtual type. Among them, the physical type is mainly based on physical miniature models, supplemented by sound, light, electricity and other multimedia technologies to provide rich interactive experience; the virtual type relies on computer simulation technology to present the simulation model of the target area through the display device, which has a high Flexibility and large amount of information. In addition, some new sand tables provide a variety of human-computer interaction experiences, such as gesture control, VR, etc., providing users with...
