Comprehensive analysis of the principle and application of interactive projection system

The definition of the interactive projection system:

The interactive projection system is also called multimedia interactive projection. It is divided into ground interactive projection, wall interactive projection, and table (tablet) interactive projection. It uses computer vision technology and projection display technology to create a magical interactive experience. The audience can interact with the content in the projected picture through the limbs. It has high novelty and appreciation. It can fully mobilize the atmosphere of the exhibition hall, increase the technological content of the exhibition, and increase the popularity of the exhibition.

The principle of the interactive projection system:

The operation principle of the interactive projection system is firstly to capture and capture the target image (such as the participant) through the capture device (sensor), and then to analyze the image and analyze the system to generate the motion of the captured object. The operational data is combined with the real-time image interaction. The system creates a tightly integrated interaction between the participants and the screen.

The technology used in the interactive projection system is a hybrid virtual reality technology and dynamic capture technology, which is a further development of virtual reality technology. Virtual reality is a technology that generates a three-dimensional image from a computer and provides the user with a three-dimensional space and interacts with it. By mixing reality, the user can also touch the real environment while manipulating the virtual image, thereby enhancing the sense of the senses.

The composition of the interactive projection system:

The interactive system consists of four parts: the first part: the signal acquisition part, which captures and captures according to the interaction requirements. The capture device has an infrared sensor, a video camcorder, a thermal camera, etc. The second part: the signal processing part, which is real-time. The collected data is analyzed, and the generated data is docked with the virtual scene system; the third part: the imaging part, which uses a projector or other developing device to present the image in a specific position, the imaging device except the projector, the plasma display, LCD monitors and LED screens can be used as carriers for interactive images. Part IV: Auxiliary equipment, such as transmission lines, mounting components, audio equipment, etc.

Features of the interactive projection system:

1. Practicality: The system can meet various realities and potential functions, environmental requirements, etc., and achieve satisfactory results.

2, reliability: the system can provide long-term continuous operation, and is stable and reliable

3. Advanced: The function and performance of the system reach the advanced level of the same display system.

4. Persistence: Select high-quality, cost-effective projection, acquisition and other equipment to ensure that the display effect of the system remains unchanged for a long time.

5. Economical: In the case of meeting the demand, the cost of system construction and use input should be as small as possible, but it can achieve better advertising, learning or other effects.

6. Convenience: The system is easy to adjust and use, the user interface is friendly, the operation process is simple, and it can be operated after a short training period.

7. Flexibility: The system has flexible hardware reconfiguration capabilities, and the dependence between devices is low. Some devices can be replaced at any time without changing all devices. The system can be expanded (installing multiple sets of software) at any time based on changes in demand without wasting resources.

8. Participation: The system supports a large number of people to participate at the same time, suitable for the characteristics of the exhibition adult flow.

The multimedia interactive projection system is a system that combines virtual simulation and image recognition technology. The operation mode is that the infrared camera captures the participant's limb movements and transmits the image to the interactive host. After the system intelligent analysis and the presentation material, the generated virtual interactive image is transmitted to the projector, and finally the entire interactive image of the participant is projected. process. According to the use environment, it can be divided into ground interactive projection, wall interactive projection and other forms.
