At present, holographic projection technology can project a small dinosaur or monster in a fixed scene to interact with people. The principle of this technology is to project an image to a certain position in the air by using optical projection technology, and then form a three-dimensional optical scene by using the intersection of laser beams or beams. The realization of this technology requires the use of professional holographic projection equipment, and the cost is relatively high, usually ranging from several thousand yuan to tens of thousands of yuan.

In addition to the equipment cost, the realization of holographic projection technology also needs certain conditions, such as a suitable projection environment, not being interfered by too many light sources, and certain light control ability. In addition, holographic projection technology needs a lot of computing and image processing technology, and also needs the support of corresponding computers and control systems.

Generally speaking, holographic projection technology is expensive and needs certain technical and environmental support. At present, it is mainly used in exhibition, performing arts, education and other fields.
