Embodiment Construction
[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0031] see figure 1 As shown, the laser pointer mouse system in the embodiment of the present invention includes a host computer (such as a personal computer, a notebook computer, etc.), a display module (such as a projector), a camera module, and a laser pointer mouse. The camera module includes a camera and a filter located in front of the camera, the center wavelength of the filter is the same as the laser wavelength emitted by the laser pointer mouse; the host is provided with a central processing module and a receiver for the laser pointer mouse; A laser switch button, a left function button corresponding to the left mouse button, and a right function button corresponding to the right mouse button are provided.
[0032] see figure 2 As shown, the image positioning method of the laser pointer mouse system in the embodiment of the presen...

The invention discloses a laser pen mouse system and an image positioning method thereof and relates to the field of laser pen-mouse interaction. The system includes a host, a display module, a central processing module, a camera module and a laser pen mouse. The central processing module is used for implementing screen positioning through a projection screen positioning algorithm and implementing mapping of screen coordinates to host system coordinates through a screen coordinate system. When the laser pen mouse emits laser, the coordinates to effective laser points in a projection image is mapped to the coordinates of a host system screen through a laser coordinate system mapping algorithm. When laser emitted by the laser pen mouse shifts, the movement of a system mouse cursor is controlled through a mouse coordinate anti-jitter algorithm. The system provided by the invention has functions of a laser pen and a mouse at the same time. The function is complete and the use is convenient, so that user experience is good.
Description
technical field [0001] The invention relates to the field of interaction between a laser pointer and a mouse, in particular to a laser pointer and mouse system and an image positioning method thereof. Background technique [0002] In occasions where a projector is required to give a speech, in order to guide the audience's sight, the speaker often uses a laser pointer to indicate the speech content on the projection screen, thereby enhancing the speech effect. However, since traditional laser pointers only have limited functions such as emitting laser light and turning pages, other operations still have to be completed with the mouse; therefore, traditional laser pointers still cause a lot of inconvenience to the speaker and affect the fluency of the speech. [0003] In order to solve the above problems, an electronic whiteboard and an air mouse based on somatosensory control have appeared in the market, but the electronic whiteboard and the air mouse have the following defe...
