The invention discloses an optical projection and screen image locating system and a locating method of the optical projection and screen image locating system and belongs to the technical field of optical projection. The optical projection and screen image locating system comprises a projector, a shooting and locating device and an infrared laser pen, wherein the projector is used for projecting an image on a projection curtain, the shooting and locating device is used for conducting shooting and locating on the image on the projection curtain, calculating the coordinate position of the position needing to be located, and transmitting relevant locating information to a processor, and the infrared laser pen emits infrared light to irradiate the image on the projection curtain and is also used for sending locating information to the shooting and locating device. By the adoption of the optical projection and screen image locating system and the locating method of the optical projection and screen image locating system, the image is projected on the projection curtain, and the image on the projection curtain is located.
Description
Technical field [0001] The present invention relates to the technical field of optical projection. Specifically, on the one hand, it relates to an optical projection and screen image positioning system; on the other hand, it relates to an optical projection and screen image positioning method. Background technique [0002] Optical projection systems play an extremely important role in modern life. Projectors are used no matter in the teaching process, or in daily company meetings or even large-scale government meetings. At present, with the development of technology, the technology of projectors has been greatly developed, and the functions are becoming more and more complete, such as intelligent control, networking, etc. However, these projectors use intelligent terminals such as Computer or smart phone, etc., during a meeting or teaching process, if you want to select a content for identification or playback, you need to walk to the computer or call an assistant to play it; thi...
