What is Projection mapping?
Projection mapping, also known as spatial augmented reality, is a technology that allows images, videos, or animations to be projected onto varied surfaces, transcending traditional flat screen displays. This technique has revolutionized the field of digital signage by enabling the transformation of mundane environments into immersive visual experiences. It leverages the power of projectors and sophisticated software to align visuals accurately with physical spaces, creating a dynamic interaction between digital content and the physical world.
The Technical Mechanics of Projection Mapping
At the core of projection mapping is the use of specialized software to manipulate projected images. This software calculates the dimensions and contours of the projection surface, allowing the projected visuals to align perfectly with the physical object. The process begins with the creation of a digital model of the target surface, which the software then uses to map the content accurately. The complexity of the software varies, from straightforward setups for simple shapes to advanced systems for intricate, multi-dimensional surfaces. The projection angle, brightness, and color balance are all meticulously adjusted to ensure the visuals appear three-dimensional and cohesive with the environment.
