Smart construction site holographic image display splicing method and system applying same

The invention relates to an intelligent construction site holographic image display splicing method and a system applying the same. The method comprises the following steps: obtaining a plurality of groups of holographic images of tower scene; taking any two holographic images in the holographic images of each group of tower scene as a first to-be-displayed spliced image and a second to-be-displayed spliced image respectively, and storing the first to-be-displayed spliced image and the second to-be-displayed spliced image in a first spatial light modulator and a second spatial light modulator respectively; performing diffraction operation on all pixels in the first to-be-displayed spliced image by using a first spatial light modulator, performing diffraction operation on all pixels in the second to-be-displayed spliced image by using a second spatial light modulator, and displaying a first three-dimensional reconstructed image corresponding to the first to-be-displayed spliced image, the second three-dimensio
