Description
Technical Field
The utility model relates to a sand table especially indicates an interactive electron sand table.
Background
The sand table is divided into a simple sand table and a permanent sand table. The simple sand table is temporarily piled up on the field by simple devices such as silt, marks and the like, and the permanent sand table is made of foam plastic plates (or three-ply boards), gypsum powder, paper pulp and other materials according to a certain proportion according to a topographic map or a field topography, can be stored for a long time and is also called as a solid sand table. The solid sand table has the characteristics of strong stereoscopic impression, visual appearance and the like, is widely applied to many fields such as military affairs, teaching, tourism, real estate development and the like, is usually used for manufacturing models for economic development planning and large-scale engineering construction, and is very popular among planning decision makers and engineering technicians. However, the physical sand table has large floor space, inconvenient carrying, monotonous expression mode, limited expression content, difficult updating and poor interactivity, and can not meet the requirements of current scientific management, planning and decision-making.
Projectors have been widely used in various departments such as military, teaching, and enterprise as an important display device. The large-format and high-definition multimedia demonstration function is completed, so that the effects of exhibition, teaching, meeting and the like are good. In 2008, the Beijing Olympic Games will open a curtain and the 2010 Shanghai world expo will have colorful special projection effects, and further the perfect combination of science and art is exclamated.
In order to overcome many defects of the traditional solid sand table, the concept of the interactive electronic sand table is provided, and the interactive electronic sand table is designed and realized by comprehensively utilizing computer vision and projection technology.
Disclosure of Invention
The invention relates to an interactive electronic sand table which is composed of a projection sand table system, a projection display system, an image acquisition interactive control system and a computer system, and is shown in figure 1. Wherein,
the projection sand table system consists of an actual sand table and a projector.
The projection display system consists of a display, a screen and a projector.
The image acquisition interactive control system consists of a laser remote controller and a camera.
The projection sand table system completes the accurate fusion of multimedia and the entity model; the projection display system displays dynamic information of the interactive target to complete rendering output of the interactive effect; the image acquisition interactive control system takes a computer vision technology as a core and provides a man-machine interaction mode; scene management, scene rendering, image acquisition and tracking positioning, interactive analysis and judgment of the whole system are all completed in an image workstation.
The interactive electronic sand table is based on an entity sand table model, virtual scene construction and multimedia information rendering are carried out by using a computer, information such as characters, pictures, videos and virtual scenes is synchronously demonstrated in various modes such as projection and display, and vivid and intuitive display is carried out by combining light, so that visitors can vividly obtain concise, beautiful and vivid dynamic information. In addition, a multi-light-spot identification tracking technology is adopted, and interaction such as picture browsing and virtual scene roaming is performed through a laser pen. The interactive electronic sand table information display mode is novel, the demonstration effect is more vivid, comprehensive and efficient, the great information amount and the interactive experience sense of the visitor are brought, and the interactive naturalness and the interactive efficiency are realized.

Detailed Description
Corresponding physical sand tables are constructed within the scope of the subsidiary middle school of the Chinese people university and the surrounding traffic environment, as shown in figure 2.
A projector is arranged right above the solid sand table, and the MingBas MP515 is selected by comprehensively considering the factors of the price, the projection brightness, the size and the like of the projector. The projector projects the digital image onto an actual sand table to form a projected sand table. The shape of the projection surface is analyzed, an image registration and image matting projection technology is adopted, the projection sand table and the entity sand table model can be seamlessly combined, the expression effect is more attractive and vivid, and the sand table has stronger dynamic property, interactivity and extensibility. The projector can project required special effects in a specific projection area, such as the effects of target convergence and crowd activities in a local area of an entity sand table.
A common liquid crystal display is arranged right in front of the solid sand table for displaying an interaction effect, and each element can be used as an object for man-machine interaction. To improve the user's interactive immersion, the display area may be increased, or information currently of interest to a person may be projected onto the projection screen, such as various promotional theme pictures, using the projection screen and projector. This constitutes a projection display system.
The user can interact with the interactive electronic sand table through the laser pen. The interactive electronic sand table adopts an optical multi-light-spot capturing method. The laser pointer emits a high brightness light spot. And a high-grade camera with stable images is adopted, is arranged above the solid sand table and in front of the display to acquire images, and is respectively used for capturing the interactive laser points on the solid sand table and the projection screen in real time and carrying out positioning and tracking so as to identify interactive operation. These constitute an image acquisition interactive control system.
The computer system is used for constructing the virtual scene and processing and rendering the multimedia information. And carrying out a series of processing on the images acquired by the camera, extracting the coordinate position of the interaction target point, analyzing the interaction event and finishing the output of the interaction effect. Specifically, the computer performs scene rendering and projection image output, and is used for explaining information concerned by a current user in real time to the user, so that dynamic interaction between a person and a sand table in a multi-dimensional manner is realized.
And after the hardware preparation is finished, the connection and debugging of the interactive electronic sand table are carried out, the video signal of the computer is divided into a projection picture of a left screen and a display picture of a right screen, the projection picture and the entity sand table are subjected to image registration, and the fusion of the projection sand table is finished by adjusting the image coordinates in the program. The camera is fixed to identify, locate, track the interaction spot. And projecting a corresponding image on the sand table through the projector, and displaying an interactive effect by using the display. Through testing, the interactive electronic sand table can realize accurate positioning and tracking of multiple light spots and accurately judge interactive events. Multimedia such as virtual scenes, pictures and the like are displayed in combination with the physical sand table, so that a user participates in interaction, and a larger information amount and a stronger immersion sense are obtained.
