Holographic phantom imaging system is a mid-air imaging system that suspends three-dimensional images in the real scene of the cabinet. The holographic phantom imaging system consists of a cabinet body, a spectroscope, and video playback equipment. Based on the principle of spectroscope imaging, a special processing of a three-dimensional model is constructed through real product shooting, and then the captured product image or product three-dimensional model image is superimposed into the scene, forming a dynamic and static product display system. People do not need to wear any polarized glasses, and they can enjoy watching the 3D phantom stereo display effects without any restraint, giving people a visual impact and a strong sense of depth.
