The invention discloses a holographic imaging sand table system. The holographic imaging sand table system comprises multiple stereoscopic models, a projector, a main control computer, a plane imaging device, a multidimensional imaging device and a touch interaction system, wherein the multiple stereoscopic models are distributed on a sand table, the plane imaging device is distributed under the projector, the multidimensional imaging device is used for converting a plane image formed by the plane imaging device into a multidimensional stereoscopic virtual image, projecting the multidimensional stereoscopic virtual image on the multiple stereoscopic models distributed on the sand table, and forming a display effect combining the virtual image with an actual image, the touch interaction system is connected with the main control computer, and the multidimensional imaging device is a multi-pyramid-shaped imaging device which is used for carrying out stereoscopic dynamic imaging at the inside middle part and is formed by splicing multiple light reflecting mediums in isosceles triangular shapes. The holographic imaging sand table system disclosed by the invention is reasonable in design, low in cost, simple and convenient in operation, flexible in control mode, high in intelligentized degree and wide in application scope, and can solve the practical problems that the traditional sand table is long in manufacturing period, is time-consuming, material-consuming and labor-consuming, and does not have a timeline function of changing architecture landform and a function of dynamically showing a distribution boosting process.
