Disclosed are a method and apparatus for controlling projection display, the method comprising: a projector collecting in real-time images of the motion trajectory of a laser pen within a set area of a projective plane; the projector performing recognition processing on the collected images of the motion trajectory of the laser pen; and the projector matching the recognition processing result with preset image data corresponding to various control operations, and if such matching succeeds, the projector processing according to the successfully-matched control operation. With this method, the projector becomes highly convenient and intelligent in operation. |
