PROJECTION SYSTEM AND PROJECTION METHOD FOR SUBWAY TRAIN TUNNEL

摘要

Provided are a projection system and a projection method for a subway train tunnel. The projection system comprises a projection unit, a projection surface of which is a tunnel wall and a control unit which is connected to the projection unit, and further comprises a distance measurement device, wherein the projection unit comprises a zoom system connected to the control unit and controlled by same. The control unit obtains data that needs to be zoomed by the zoom system by means of calculation and transmits same to the zoom system for zooming. The system and method provided in the present invention make full use of the large windows of a carriage of the train and the tunnel to perform effective and dynamic information transmission, and have the beneficial effects of a lower cost, being easy to control and having a good projection effect when compared to the prior art.
