Ground interactive projection is a cutting-edge technology that allows users to interact with virtual images projected onto the ground without the need for any additional devices. By simply using their feet or hands, participants can engage with the virtual scenes, creating a highly immersive and entertaining experience. This technology is widely used in exhibitions, shopping malls, and other public spaces to attract crowds and enhance engagement. But how does ground LiDAR interactive projection achieve human-computer interaction? Let’s dive into the details.
The Principle of Ground Interactive Projection System
The ground interactive projection system works by projecting images onto the ground using a projector suspended from the ceiling. When a participant steps into the projection area, the system recognizes their movements through advanced sensors and cameras. This allows the participant to interact with the virtual scene using their feet or body movements, creating dynamic and responsive visual effects.
Key Components of Ground Interactive Projection System
1. Capture Devices and Projection Equipment
The system relies on capture devices such as sensors and cameras to detect the participant’s movements. A projector is used to display the content, while a camera tracks the participant’s motion. Typically, the system uses a projector with an infrared filter and a camera capable of emitting near-infrared light. This setup ensures accurate content projection and motion tracking.
2. Separation of Human and Virtual Background
To distinguish between the participant and the virtual background, the system uses infrared cameras. These cameras emit infrared light, which reflects off the participant and is captured by the camera, creating a clear image. The projector displays black content, while the participant’s movements appear as white, resulting in a monochromatic image that separates the human from the virtual environment.
3. Motion Detection
The system employs image differential technology to detect motion. By comparing consecutive frames captured by the camera, the system identifies the moving parts (i.e., the participant). This ensures that any movement is accurately tracked and translated into interactive effects.
4. Data Analysis and Projection
Once the system captures and analyzes the participant’s movements, it generates corresponding virtual effects and projects them onto the ground. Advanced techniques such as camera calibration, optical flow analysis, and performance optimization are also used to enhance the interactive experience.
Applications of Ground LiDAR Interactive Projection
Ground interactive projection offers a wide range of interactive experiences, making it a versatile tool for entertainment and advertising. Here are some popular applications:
1. Interactive Football
Participants can control a virtual football using their feet. By stepping into the projection area, they can kick the ball and score goals, creating a fun and competitive game.
2. Fish and Water Interaction
In this scenario, a virtual pool with swimming fish is projected onto the ground. When participants step into the area, ripples form around their feet, and the fish swim away, creating a lifelike aquatic experience.
3. Whack-a-Mole Game
Participants can play a virtual whack-a-mole game by stepping on the moles that appear on the ground. This interactive game is both entertaining and engaging, attracting people of all ages.
