Patent US 10,927,132 B2 describes a system and method for displaying an image on a curved projection screen using a single projection device. The invention addresses the challenges of accurately projecting images onto non-planar surfaces, particularly curved screens, without distortion, which typically requires complex multi-projector setups or specialized optics.
A key novel aspect of this patent is its approach to correcting geometric distortion and achieving focus across a curved surface using a single projector. The system employs a "mask map" and a "depth map" to achieve this. The mask map defines the shape of the projected image on the curved screen, ensuring that the image fits the screen's boundaries without spillover. The depth map, on the other hand, contains information about the three-dimensional curvature of the projection surface relative to the projector. This depth information is used to compute geometric corrections that are applied to the image data before projection. Specifically, the system pre-distorts the image such that when it hits the curved screen, it appears geometrically correct to the viewer. Furthermore, the patent describes a "focus map" that guides the adjustment of focus across different parts of the image, compensating for the varying distances between the projector and the curved screen. This combined approach of geometric and focus correction enables high-quality projection onto curved surfaces from a single, potentially off-axis, projector.
The commercial potential of this invention is significant across various industries where immersive visual experiences, efficient display solutions, and complex projection environments are desired. The ability to use a single projector to achieve high-quality images on curved screens offers substantial cost savings, simplifies setup, and reduces maintenance compared to multi-projector systems.
Possible applications include:
Immersive Simulation and Training: Creating highly realistic and seamless immersive environments for flight simulators, driving simulators, military training, and industrial operations, where a continuous, wide field of view is crucial for effective training.
Planetariums and Theaters: Projecting high-resolution content onto dome or curved screens in planetariums, cinemas, and specialized entertainment venues, providing a more engaging and immersive experience for audiences without visible seams or alignment issues common with multiple projectors.
Theme Parks and Attractions: Enhancing visual effects and storytelling in theme park rides and interactive exhibits by seamlessly projecting dynamic content onto uniquely shaped or curved surfaces, improving guest immersion.
Data Visualization and Control Rooms: Displaying complex data or monitoring environments on large, curved screens in control rooms, command centers, and scientific visualization labs, providing operators and analysts with a comprehensive and easy-to-view interface.
Digital Signage and Advertising: Creating striking and dynamic digital signage displays on curved architectural elements or artistic installations in public spaces, retail environments, and corporate lobbies, capturing audience attention more effectively.
Automotive and Transportation Displays: Developing advanced heads-up displays or interior vehicle displays that project information onto curved surfaces within the vehicle, improving ergonomics and user experience.
This patent offers a versatile and cost-effective solution for advanced projection, providing a pathway to more immersive, efficient, and visually compelling display systems across a broad spectrum of commercial and specialized applications.
