Abstract

The invention discloses a positioning system and method for a laser pen mouse. The positioning system for the laser pen mouse comprises the laser pen mouse and a projector. The system has the technical scheme that a camera is arranged on the projector, and the laser pen mouse is provided with a left control key and a right control key which correspond to the left key and the right key of the mouse. When the left control key or the right control key on the laser pen mouse is pressed down, a projection image is obtained through the camera for carrying out positioning, the relative position of a laser light spot on the projection image is identified to obtain the coordinate of a mouse cursor in an operating system to enable the operating system to operate a corresponding operation on the coordinate so as to realize the remote-control operation of the laser pen mouse, users can obtain visual and accurate operation experience and are free from the influence of the distance of the laser pen mouse so as to bring convenience to teaching, speeches and the like, and a function that the laser pen mouse can click a position where the laser pen mouse points to can be achieved.

Description

technical field [0001] The invention relates to the technical field of projector control, in particular to a laser pen mouse positioning system and method. Background technique [0002] Large-screen projection is more and more widely used in multimedia teaching, speeches, teleconferencing and other activities. In order to attract the audience, the speaker usually stands on the edge of the projection screen, and uses the laser emitted by the laser pointer to indicate the key content of the speech on the projection screen, so as to improve the concentration of the audience. However, the existing laser pointer usually only has the function of turning pages and does not have the function of mouse operation. When the mouse operation is required, the speaker must return to the computer to perform mouse operation. . Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a laser pen mouse positioning s...
