The intelligent exhibition hall system based on holographic images of claim 8, wherein when the motion sensing module senses that multiple visitors visit at the same time, the central control module controls the corresponding camera of the motion sensing module to collect the image data of the corresponding visitor, and the central control module only determines the person with the complete facial image data at the highest position as the visitor.
10. The intelligent exhibition hall system based on holographic images of claim 8, wherein the central control module is configured with a preset time Tn, when none of the motion sensing modules in the exhibition hall senses a visitor, the central control module starts to count down from Tn, and when Tn returns to zero, the central control module adjusts the display levels of all the image display modules in the exhibition hall to 0.
