Outdoor naked-eye 3D technology is a technology that can present 3D effects in an outdoor environment without the need to wear any special glasses or equipment. Its main features include:

 

Viewing with naked eyes: Users can watch 3D content directly in an outdoor environment without wearing any special glasses.

 

High brightness and contrast: Naked-eye 3D technology can provide sufficient brightness and contrast in outdoor environments to ensure that the picture is clearly visible.

 

Wide viewing angle: Users can experience stable 3D effects over a wide viewing angle without being restricted by the viewing angle.

 

Environmental adaptability: Adapt to different lighting conditions and ambient light to ensure that it can still provide a good 3D experience in different outdoor scenes.

 

 

Outdoor naked-eye 3D technology is widely used in many fields, including but not limited to:

 

Outdoor advertising and digital signage: Using naked-eye 3D technology, more eye-catching three-dimensional advertisements can be presented on outdoor billboards and digital signage to improve advertising effects.

 

Outdoor entertainment: Set up naked-eye 3D screens in public places such as theme parks and squares to provide tourists with a more vivid entertainment experience.

 

Outdoor activities: Use naked-eye 3D technology in outdoor performances, music festivals and other activities to bring a more shocking and immersive feeling to the audience.

 

Outdoor navigation and maps: Set up naked-eye 3D screens at urban public transportation stations, squares and other places to provide more intuitive navigation and map information.

 

How it works 
 

Naked-eye 3D,  it means that the naked eye can intuitively see three-dimensional visual effects without the help of external equipment such as glasses and helmets. As we all know, our human brain is an extremely complex nervous system. In the visual system, since the distance between our two eyes is about 60mm, when we look at an object, the image of the object on the retina of the left eye and the right eye will exist. A certain degree of horizontal difference, then this phenomenon is what we usually call parallax. It is precisely because of the existence of this parallax that our brain can judge the distance of an object. At the same time, the brain will form a three-dimensional stereoscopic feeling through the fusion reflection of the optic nerve center and the visual psychological reaction of the two parallax images reflected in the eyes. This is the basic principle of naked-eye 3D imaging.

 

In addition, the naked-eye 3D visual effect ≠ the naked-eye 3D technology. The naked-eye 3D visual effect is more of a pseudo-three-dimensional effect formed by using optical illusions, while the naked-eye 3D technology is an imaging technology. Naked-eye 3D technology integrates optics, image processing and computer vision technology to achieve the miracle of projecting images from different viewing angles. Through special display technology and image processing methods, naked-eye 3D technology can simultaneously project images from different viewing angles on the screen, allowing our left and right eyes to receive different images. In this way, when our brains process these images, they will have a three-dimensional sense, as if the real world is unfolding before our eyes.

 

 

Outdoor naked-eye 3D technology has broad development prospects and may show the following trends in the future:

 

Technological improvements and innovations: There will be more improvements and innovations in key technologies such as light field display and viewpoint tracking to improve the stability and effects of naked-eye 3D technology.

 

Expansion of application fields: With the continuous advancement of technology, outdoor naked-eye 3D technology will be applied in more fields, including education, medical care, tourism, etc.

 

Intelligent interactive functions: Future outdoor naked-eye 3D systems may add more intelligent interactive functions to provide users with a more in-depth interactive experience.

 

Cost decline: As the technology matures and the market expands, manufacturing costs are likely to decline, making naked-eye 3D technology more popular and affordable.

 

Taken together, outdoor naked-eye 3D technology is expected to become an important part of the future digital entertainment and information display fields, providing users with a more immersive and engaging experience.
