A kind of imaging and projecting system equipment application,The imaging and projecting system system includes a plurality of light projection devices； An at least image capture unit； One is coupled the control device of connection for a plurality of light projection devices； And one coupled connection for an at least image capture unit and the control device respectively display unit； It utilizes each light projection device and an at least image capture unit,Reach can instant playback guiding message or the method for interaction space position in what operating space,Operating space Hou is entered to any subject matter,The information that the institute projects will be imaged on the what subject matter,Then the image capture unit will can be used to obtain three-dimensional space location information or 3D information that operating space intersects information and the subject matter,The position of the mobile subject matter in operating space is obtained via the control device again； Three-dimensional space location information image Hou that its operating space intersects information and subject matter is captured by the image capture unit,It is able to carry out interaction and guidance function.一種成像投影系統設備應用，該成像投影系統係包含複數個光線投射裝置；至少一影像擷取裝置；一供該複數個光線投射裝置予以耦接連結之控制裝置；及一分別供該至少一影像擷取裝置與該控制裝置予以耦接連結之顯示單元；其利用該各光線投射裝置與該至少一影像擷取裝置，達到可於操作空間中即時顯示導引訊息或互動空間位置之方法，帶有任一標的物進入至操作空間後，該所投影之資訊將成像於該標的物上，接著該影像擷取裝置將可用來取得操作空間交叉資訊與該標的物之三度空間位置資訊或3D資訊，再經由該控制裝置取得操作空間移動標的物之位置；藉由該影像擷取裝置擷取其操作空間交叉資訊與標的物之三度空間位置資訊影像後，得以進行互動與導引功能。
