Gesture control projection display device and control method thereof

Abstract

The invention relates to a gesture control projection display device. The gesture control projection display device comprises a projection device, a distance sensing device, an image acquisition device and a central system device, wherein the projection device projects and displays an image to a projection surface; the distance sensing device senses a first distance and a second distance; the image acquisition device acquires a gesture image of a control gesture; the central system device is connected with the projection device, the distance sensing device and the image acquisition device; and the central system device is used for determining an effective gesture space according to the first distance, judging whether the control gesture is positioned in the effective gesture space or not according to the second distance, processing the gesture image of the control gesture positioned in the effective gesture space and controlling a display image projected by the projection device. The gesture control projection display device has a simple structure, can simply realize operation and control on the projected display image by utilizing the control gesture, enhances the interactive experience and contributes to realizing miniaturization, integration and intelligentization. The invention further relates to a control method of the gesture control projection display device.

Description

Technical field [0001] The present invention relates to projection display technology, and in particular to a gesture control projection display device and a control method thereof. Background technique [0002] With the improvement of the quality of life, people are more and more fond of the visual experience brought by the large screen display, and the projection system is gradually favored because it can project the displayed image on the large screen or the wall for display. Currently, a traditional projection system includes not only a projector and a screen, but also smart devices such as computers, notebooks and mobile phones connected to the projector. In addition, traditional projection systems also require operation control devices such as a mouse, a keyboard or a laser pointer to realize basic operation control of displayed images. Therefore, the construction of the traditional projection system requires a lot of equipment, the connection structure is complicated...
