Introduction to projection mapping technology
Projection mapping technology, also known as 3D mapping, is a projection technique that can transform an object (mostly an irregularly shaped object) into a display surface of an image projection. The object can be a large landscape like a building or a building, a small outdoor object or a dramatic set. With special software, you can project two-dimensional or three-dimensional images with a program, and adjust the image with the object to make the image conform to the object and its environment. The software can interact with the projector and project at a specific angle onto the surface of the object. This technology has been used by artists and advertising designers to add extra dimensions, create visual illusions and motion concepts to static objects. Light-shadow projections are often combined with sound or triggered by sound to produce a visual impression.
The appearance of the projection mapping technology breaks the limitation of the projection on the carrier. It can make any surface become the carrier of the projection, and the projection picture and the carrier are perfectly integrated, as if the picture is a part of the carrier itself.
The perfect blend of objects and animation
The projection mapping technology is composed of single or multiple projectors. It is a comprehensive visualization system project integrating hardware platform and professional display equipment. The whole system includes display objects, projectors, advanced simulation graphics computing clusters, and related auxiliary components. It produces a highly realistic, three-dimensional sense of three-dimensional scenes, coupled with music and sound effects, to achieve a shocking effect. Currently, Mapping technology is mostly used for art display and commercial projection.
All projectors are designed for flat projection screens, and the projected images are also rectangular (usually 4:3 or 16:9), and when such projectors project images onto non-planar projection screens In this case, image distortion caused by each projector projecting onto the circular screen is distorted. In order to obtain the correct image display effect on such a non-planar screen, the generated real-time image must be performed. Processing, such image distortion distortion correction processing is called nonlinear distortion and digital geometric correction. The light sculpture projection is mainly designed for the projection surface of the three-dimensional object. We can pick the surface contour mask of the object that needs to be projected for the customer, and provide convenience for displaying some special shape objects, automobile shape, sculpture shape, irregular wall. Body, etc., can be easily competent.
Mapping technology on the light show
Mapping technology on outdoor
A short explanation from a technical point of view: 3D mapping is mainly a screen mosaic project. It mainly covers three parts: projection system, playback system and splicing engineering. The projection system is the core unit, which generally uses high-end projection devices with more than 20,000 lumens for projection. The giant images are usually spliced together. Through the fusion technology, a whole picture with no gaps, brighter, larger and higher resolution is displayed, supplemented by a playback system to achieve the perfect effect of sound and light.
Projection Mapping Feature
1. With its characteristics of shock + novelty, cool + high technology, it has become the most powerful means of warning to attract the attention of the crowd.
2. The projection object is extensive, and the customized motion is projected onto the body through 3D projection, such as ground projection, water curtain projection, flowing body projection, scene projection, landscape projection, fornix projection and so on.
3. The immersive system can be combined with the distribution of new products, and the fine characteristics of the products can be achieved by means of immersion.
