Abstract

The invention provides a projection interactive installation capable of realizing a correction function. The projection interactive installation comprises a master control processing module, an interactive module and an electronic stylus, wherein the interactive module comprises an optical lens, a filter switcher and an image sensor which are arranged in sequence; the master control processing module is respectively connected with a PC (personal computer) and the image sensor; the filter switcher is controlled by the master control processing module to switch a filter to a visible light-transmitting filter, and a picture is projected by the PC through a projector; the projected picture is collected by the image sensor through the optical lens, and written coordinates of the obtained picture are analyzed through the master control processing module; correction positioning is performed on the written coordinates of the obtained picture and display coordinates projected on an electronic whiteboard by the projector by the master control processing module; after the correction positioning is performed, the filter switcher is controlled by the master control processing module to switch the filter to an infrared light-transmitting spike filter, and then, the electronic stylus can write. According to the projection interactive installation provided by the invention, a user does not need to participate in operation during the positioning process of the interactive module, and thus, full-automatic positioning can be realized.

Description

technical field [0001] The invention relates to the technical field of optical image interactive projection, in particular to a projection interactive device capable of realizing a correction function. Background technique [0002] The projection interactive modules currently on the market generally use filters to physically filter out the light emitted by non-photoelectric pens, and only collect the light emitted by the photoelectric pens. So the lens can't see the normal environment, only the infrared light that the filter can pass through. This type of product needs to be positioned before use. The positioning method is generally that the projector reveals a positioning screen. The screen has several fixed points. The user holds the infrared photoelectric pen and clicks on these points according to the prompt Let the module collect the coordinates. The purpose of positioning is to establish the connection between the actual coordinates and the displayed coordinates in th...
