The invention provides a touch recognition method, device and equipment based on infrared and visible light and a medium, and is applied to a projector, and the method comprises the steps: projecting infrared light to a to-be-projected plane through a signal transmitting unit, generating a first echelette grating, then projecting an operation interface to the to-be-projected plane, and generating a second echelette grating according to the operation of the operation interface; the infrared camera continuously shoots the second echelette grating, obtained first light spot information is transmitted to the calculation and analysis unit, live-action picture information obtained by shooting the to-be-projected plane through the color camera is transmitted to the calculation and analysis unit, and the calculation and analysis unit determines a corresponding adjustment mode according to the first light spot information and the live-action picture information. And updating the projection content according to the adjustment mode. According to the method provided by the invention, through the arrangement of the double cameras, whether the light spot information is generated by the touch of the user or the article can be accurately determined, so that the situation of mistaken touch is reduced, the accuracy of touch identification is improved, and the user experience is improved.
Description
technical field [0001] The present invention relates to the field of projection technology, and in particular, to a touch recognition method, device, device and medium based on infrared and visible light. Background technique [0002] With the continuous multi-functional development of electronic devices, the traditional button-type operation interface or touch-screen interface has gradually been unable to meet the needs of users. Therefore, interactive technology has begun to flourish, and projection equipment that supports projection touch has also become more and more popular. more people's attention. [0003] In the prior art, the projection device is mainly based on the infrared depth vision method to locate and identify the touch object. This identification method is easily limited by the influence of the environment. The infrared touch identification method requires the infrared light in the current environment to be in a relatively high level. If the infrared intens...
