The invention discloses a running exercise experience scene type 3D holographic projection device. The running exercise experience scene type 3D holographic projection device comprises a treadmill anda 3D holographic projector, a sensor is installed on the treadmill, and the 3D holographic projector is installed at the front portion, the rear portion or the portion over the treadmill, projects tothe two sides or the periphery of the treadmill and comprises a central processor, an image data storage module, an image bottom image generating module, a digital conversion module, a 3D image projection module and a signal receiving module, wherein the image data storage module, the image bottom image generating module, the digital conversion module, the 3D image projection module and the signal receiving module are connected with the central processor; the sensor is in communication with the signal receiving module. Compared with the prior art, the running exercise experience scene type 3Dholographic projection device has the advantages that the device is not limited by space and light, a stereoscopic dynamic space of a virtual reality environment can be experienced with bared eyes simply without wearing glasses or other accessory products, and the limit in an existing 3D movie technology that audiences can only watch the virtual reality environment by wearing the glasses is broken through.
