System and Method for Recording and Visualization of a 3D Scene in Real Time

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention relates to a system and method for capturing and visualizing a 3D scene in real-time using a movable image capturing device, such as a camera or 3D sensor. The captured data is sent to a processing unit that incrementally builds a 3D model, which can then be visualized on a remote display device (such as a VR headset or screen). The system supports interactive and guided scanning, real-time incremental reconstruction, and independent asynchronous communication between capturing, processing, and visualization components. Users can explore partially reconstructed scenes immediately, with live updates as more data is captured.

Use CasesContent extracted from patent full text and abstract with AI.

• Remote inspection or walkthroughs of buildings, homes, or industrial sites for real estate, construction monitoring, or virtual tourism.
• Remote technical support and collaboration, for example, guiding a field technician while an expert remotely explores the environment.
• Virtual reality (VR) or augmented reality (AR) reconstructions for immersive training, simulation, or education.
• Remote repairs and maintenance, allowing experts to visualize complex 3D equipment environments as a local operator captures them.
• Heritage preservation and documentation of archeological or historical sites to enable remote interactive exploration.
• Law enforcement or forensic investigation to document and revisit crime or accident scenes.
• Interactive 3D content creation for gaming, film sets, or digital twin applications.

BenefitsContent extracted from patent full text and abstract with AI.

• Real-time visualization: Users can start exploring a scene instantly, even before full reconstruction is complete, enhancing immersion and efficiency.
• Incremental 3D modeling: The system builds models on the fly as data is acquired, allowing for flexible, dynamic, and partial scene reconstruction.
• Remote and asynchronous operation: Capturing, processing, and visualization can be performed in separate locations and at different rates, allowing for scalable and distributed collaboration.
• Guided scanning: The system can provide feedback or instructions to the operator, increasing data capture efficiency and ensuring key areas are recorded.
• Multi-user support: Multiple remote users can independently explore the same or different parts of a 3D scene simultaneously.
• Reduced bandwidth: Only relevant display information is sent to remote viewers, avoiding the need to transmit full 3D models, which is efficient for networked or cloud-based solutions.
• Extensible with CAD overlays and annotations: Additional information—such as pointers, highlights, or superimposed models—can enhance communication and collaboration.
