3D全息投影是一种无需配戴眼镜的3D技术,观众可以看到立体的虚拟人物。这项技术在一些博物馆应用较多。全息立体投影设备不是利用数码技术实现的,而是投影设备将不同角度影像投影至一种国外进口的全息膜上,让你看不到不属于你自身角度的其他图像,因而实现了真正的全息立体影像。 3D holographic projection is a kind of 3D technology without wearing glasses, the audience can see three-dimensional virtual characters. This technique is used more in some museums. Instead of using digital technology to implement holographic stereoscopic projection equipment, projection equipment projects images of different angles onto a holographic film imported from abroad so that you can not see other images that are not your own, thus enabling true holography Three-dimensional image.
