Abstract

The invention provides a projection control recognition method and device and control equipment, after a control light spot emitted by the control equipment is recognized on a projection picture, a to-be-recognized image containing the projection picture and the control light spot is shot, and the position information of the control light spot in the to-be-recognized image is obtained by performing image recognition processing on the to-be-recognized image. And control information sent by the control equipment is determined according to the obtained position information. According to the scheme, the position information of the control light spot is obtained in an image recognition mode, then the control information is determined, and the effect of rapidly and conveniently determining the corresponding control information through the position information can be achieved.

Description

technical field [0001] The present application relates to the field of projection technology, and in particular, to a projection control identification method, device, and control device. Background technique [0002] With the development of projection technology, projection equipment is more and more widely used in people's daily life or work. Nowadays, more and more families choose to use projection equipment for TV projection, game projection, etc. In addition, in their daily work, more and more corporate employees choose to use projection equipment for presentations and document explanations. In the existing projector virtual touch technology, the infrared receiver is generally used to detect the infrared light emitted by the infrared touch device, and then the touch information sent by the touch device is determined to complete the touch operation. In the existing control methods, there is a problem that the detection and identification methods are complicated, and it ...
