<p>The present invention provides a subway train tunnel projection system and method. The projection system comprises a projection unit, wherein a projection plane of the projection unit is a tunnel wall; a control unit, connected with the projection unit; and a distance measuring device, connected with the control unit, and capable of measuring distance data from the surface of the tunnel wall to the projection unit and sending the data to the control unit, wherein the projection unit comprises a zooming system that is connected with the control unit and controlled by the control unit; and the control unit calculates data required for zooming by the zooming system, and transmits the data to the zooming system for zooming. The system and the method provided by the present invention make full use of large windows of subway compartments and the tunnel to conduct effective and dynamic information propagation, and compared with the prior art, the system and the method have the beneficial effects of low cost, easy control, and good projection effect.</p> |
