What is holographic projection?

The projector adopts high-end alignment, fusion and calibration technology to create an immersive visual experience and provide viewers with a truly unforgettable immersive visual experience.

Holographic projection is widely used in large-scale activities, leisure and entertainment, cultural and tourist attractions, museums, science and technology museums, digital movies and other industries.

Besides holographic projection and naked-eye 3D, the most important thing is the content of the video, which determines whether the final effect can attract the audience. Amazing holographic projection content material can always arouse the interest of the audience and forward it on its own.

In some activity sites, the projectors needed are different according to the size of the project, depending on the location, size and shape (full dome and partial dome, cylindrical, curved or flat; Ceiling, floor or any 3D-shaped object).

From 3D holographic projection to immersion projection, we focus on creative use of technology to design unforgettable experiences.

Dome projection is one of the techniques to project the projected image onto a sphere. Projecting the image onto a huge dome-shaped screen that simulates the skyline provides the audience with a completely immersive viewing experience. Dome projection is a high-tech equipment, which involves complex software and hardware integration and complex calibration and calibration process.

Camera calibration The calibrated camera is used to measure the projection screen, which improves the calibration accuracy, thus eliminating hardware errors and improving the quality of the projection system. The camera is calibrated for different distances, and the parameter file contains distortion coefficient, focal length and geometric correction value of the chip.

Calibration Panel When calibrating the vision system, the calibration panel is used as an accurate reference source. Our calibration board is tested based on certified high-precision coordinate measurement technology.

In addition to large-scale projection performances, projection technology can also be used for brand building or educational purposes of small companies. Use touch screen, sensor or radar to realize interactive experience. When someone touches a graphic, it will trigger animation and special effects to tell a story.

The projected touch wall is interactive, interesting and attractive, so it is a very good marketing and educational tool.

About educational purposes? The Hong Kong Museum of History held an exhibition entitled "The Road to Modernization-Seventy Years of People's Republic of China (PRC)". The projected touch wall with graphic background shows the Hong Kong-Zhuhai-Macao Bridge, its spectacular infrastructure and interesting facts. By clicking on the different icons on the bridge, the animation starts to play and provides the details of the bridge information.
