LiDAR interactive projection systems consist of various hardware and software components that work together to create an engaging interactive experience. Here’s a breakdown of the essential elements involved:
1. Projectors
- Quantity: One or more projectors are used, as there is no limit to the number of interaction points. This allows multiple users to experience the interaction simultaneously.
- Requirements: High-lumen projectors are necessary to provide clear and vivid interactive experiences, especially in exhibition settings where projection blending is often required.
2. Projector Mounting Bracket
- Installation: Typically, projectors are mounted at a height of over 3 meters for safety reasons. The mounting brackets must support the weight and ensure stability.
3. LiDAR System
- Components: The LiDAR system includes infrared lights and sensors that detect user interactions on the projected surface.
- Functionality: Users can perform various actions such as clicking, dragging, or rotating due to sensors installed on the projection surface. The infrared lights facilitate communication and recognition without being affected by ambient light conditions, ensuring a seamless interaction experience in both dark and brightly lit environments.
4. Video Content
- Types: The content projected onto surfaces can be categorized into standard visuals and interactive elements tailored to user needs.
5. Software System
- Types: The interactive software includes projection blending software and interaction software that manage how content is displayed and how users interact with it.
6. Central Control System, Computer, and Audio System
- These components manage the overall operation of the interactive projection system, including content playback and user interaction feedback.
Installation Methods for LiDAR Interactive Projection
The installation of LiDAR systems can vary based on specific requirements:
- Above Wall or LCD Screen: LiDAR can be mounted above the projection area.
- Below Wall or LCD Screen: Alternatively, it can be positioned below for different interaction dynamics.
- Free-standing Operations: Systems can operate away from walls or in open spaces.
- Height Adjustments: The distance from the LiDAR to the ground can be adjusted based on its radius, allowing for flexible installation setups.
Conclusion
LiDAR interactive projection systems combine advanced hardware and software to create immersive experiences across various environments. By leveraging technologies like LiDAR sensing and high-quality projection, these systems facilitate natural interactions that enhance engagement in educational settings, exhibitions, and more.
