Development Level and Composition of Virtual Projection

Development Level and Composition of Virtual Projection
Interactive induction projection system mainly includes: ground interactive induction projection system, desktop interactive induction projection system, wall interactive induction projection system and interactive induction back projection system. The interactive projection system adopts advanced computer vision technology and projection display technology to create a magic and dynamic interactive experience.

Different from the traditional touch screen, without any other media, users can directly use their feet or hands to interact with the virtual scene on the ordinary projection screen, so that users can enter a wonderful world of virtual and reality integration, real and imaginary world.

1. What is the principle of interactive system of virtual projection technology?

The interactive induction projection system is controlled by a projector. The computer and audio system can directly project images to the ground and wall. However, its projection is divided into two layers of image effect. The first layer is the image in static state, and the second layer is the image effect of interaction with the audience by using infrared sensing technology to make the image change with the movement of the audience entering the picture.

2. What kind of development level has virtual projector technology reached at present?

At present, virtual interaction technology has completed the human-computer interaction part, and there are many kinds of simulation with the nature or virtual world. The reaction delay of interaction is 0.05 seconds.

3. What are the components of virtual reality projector interactive system?

The interactive system consists of four parts.
The first part: the signal acquisition part, according to the interactive requirements to capture and shoot. The capture equipment includes infrared sensor, video camera, thermal camera, etc;
The second part: the signal processing part, which analyzes the data collected in real time and connects the data with the virtual scene system;
The third part: the imaging part, the use of projectors or other imaging equipment to present the image in a specific location, imaging equipment in addition to projectors, plasma display, LCD, LED screen can be used as the carrier of interactive image.
The fourth part: auxiliary equipment, such as transmission lines, installation components, audio devices, etc.
