Depth detection in interactive projection system based on one-shot black-and-white stripe pattern.

Area of Science:

• Computer Vision
• Human-Computer Interaction
• 3D Reconstruction

Background:

• Conventional interactive projection systems often lack depth perception.
• Existing methods may require specialized equipment or screens.
• Accurate 3D interaction is crucial for immersive virtual experiences.

Purpose of the Study:

• To develop a novel method for estimating depth information in interactive projection systems.
• To enable 3D interaction without auxiliary equipment or special screens.
• To provide a more direct sense of virtual interaction.

Main Methods:

• Projecting a one-shot black-and-white stripe pattern onto a screen.
• Capturing the deformed pattern using a charge-coupled device (CCD) camera.
• Employing an algorithm based on simultaneous object/shadow detection for correspondence.
• Calculating depth information using the triangulation principle.

Main Results:

• The proposed method successfully estimates depth information from 2D coordinates.
• Effectiveness in depth detection was verified through simulations and experiments.
• The system allows for 3D interaction without specialized hardware or screens.

Conclusions:

• The novel method effectively provides depth information for interactive projection systems.
• This technology enhances virtual interaction by enabling true 3D perception.
• The approach offers a cost-effective and accessible solution for 3D interaction.
