Defining Projection Mapping
Projection mapping, also known as spatial augmented reality or video mapping, involves the projection of light onto objects or surfaces to create the illusion of transforming their appearance.
Unlike traditional projection methods that utilize flat screens, projection mapping allows for the adaptation of projections to complex three-dimensional shapes, making it possible to create illusions of depth, movement, and interactivity.
The Process
Object Selection: The first step in projection mapping is choosing an object or surface onto which the projection will be applied. This can range from buildings, sculptures, and vehicles to stages, furniture, and even human bodies.
3D Scanning and Modeling: Once the object is selected, it is necessary to capture its shape and dimensions accurately. This is achieved through 3D scanning techniques, such as laser scanning or photogrammetry, which create a digital representation of the object. The 3D model allows the content creators to precisely align the digital visuals with the physical object.
Content Creation: The next phase involves creating or adapting visual content specifically designed for the chosen object. This content can be a combination of images, videos, animations, or even interactive elements. The content is meticulously designed to match the object's shape, contours, and details, ensuring a seamless projection.
Projection Setup: To project the visuals onto the object, multiple projectors are strategically positioned around the area. These projectors need to be precisely calibrated and aligned to ensure accurate mapping and seamless blending of the projected images.
Calibration and Mapping: Calibration is a crucial step in projection mapping. Using specialized software, the projection system is aligned with the object's 3D model.
This process involves adjusting the projectors' lens settings, position, and orientation to match the virtual representation of the object. This alignment allows the projected content to seamlessly fit onto the object's surface, regardless of its irregularities.
Projection and Interactivity: Once the calibration is complete, the projection mapping system is ready to bring the object to life. The projectors beam the visuals onto the object, carefully aligning and mapping each element onto its respective surface.
The content can be programmed to synchronize with music, motion sensors, or interactive devices, adding an extra layer of immersion and engagement.
Applications and Impact
Projection mapping has transcended various domains and has become a staple in several industries. Based on our research, here are some of the most well-known applications:
- Art and Installations: Projection mapping has provided artists with new ways to express their creativity and transform spaces. Sculptures, art installations, and entire buildings serve as canvases for dynamic and visually stunning creations
- Entertainment and Events: Projection mapping has revolutionized live performances, concerts, and theatrical productions. It enables the creation of immersive and visually captivating experiences, blending the real and virtual worlds seamlessly.
- Advertising and Branding: Projection mapping offers a unique and attention-grabbing approach to marketing and advertising. From storefronts to product launches, projection mapping provides brands with an impactful way to engage and mesmerize their audiences, leaving a lasting impression and enhancing brand recognition.
- Architectural Projection: Projection mapping has transformed the way we perceive buildings and structures. Architectural facades can be turned into dynamic displays, showcasing stunning visuals and narratives, enhancing the overall aesthetics of urban landscapes.
- Educational and Museums: Projection mapping has found its way into educational settings and museums, providing interactive and informative experiences. Exhibits can come to life, offering visitors a deeper understanding of historical events, scientific concepts, or artistic movements.
- Home entertainment: Projection mapping is also used at home by projecting images onto their homes for Halloween, Christmas and other holidays or parties. This allows you to spice up family nights, delight your neighbors, or bring even more fun to your home.
