Abstract
The utility model discloses a kind of visual projection's interactive system based on pattern-recognition, including projecting apparatus, camera, infrared tube, infrared fileter and PC, the camera is fixed on support, support vertical is fixed on level ground, the camera is connected with PC, infrared tube is arranged on the bottom of support, infrared fileter is arranged on cam lens rear portion, the projecting apparatus is arranged on the rear side of support, it is connected higher than camera and with PC, and the display picture of PC is projected between user and camera and form view field, the utility model is when user tramples on the region again, its foot produces diffusing reflection near infrared light and forms highlighted target hot spot.
Description
Technical field
It the utility model is related to computer vision and area of pattern recognition, and in particular to a kind of vision based on pattern-recognition
Project interactive system.
Background technology
Interaction is that augmented reality is combined virtual object with reality scene, and user can be allowed to be carried out with virtual environment
Interaction.It allows user to produce a kind of sensation on the spot in person, and builds a kind of brand-new dynamic interactive experience for it.And regard
It is an important application of augmented reality to feel projection interactive system, and it is to rely on advanced computer vision technique and Projection Display
Technology, create a kind of realistic interactive mode.
Utility model content
In order to overcome shortcoming and deficiency existing for prior art, the purpose of this utility model is to provide a kind of based on pattern knowledge
Other visual projection's interactive system.
The utility model adopts the following technical scheme that：
A kind of visual projection's interactive system based on pattern-recognition, including projecting apparatus, camera, infrared tube, infrared filtering
Piece and PC；
The camera is fixed on support, and support vertical is fixed on level ground, and the camera is connected with PC,
Infrared tube is arranged on the bottom of support, and infrared fileter is arranged on cam lens rear portion, and the projecting apparatus is arranged on support
Rear side, it is connected higher than camera and with PC, and the display picture of PC is projected between user and camera and formed
View field.
The infrared tube is specially word line infrared tube.
The beneficial effects of the utility model：
(1) target is protruded using near-infrared secondary light source, in view field, one near-infrared light source covering of formation is put down
Face；
(2) when user is trampling the region, its foot produces diffusing reflection near infrared light and forms highlighted target light
Spot；
(3) simultaneously, cam lens with the addition of infrared fileter, reduce the complexity of image background.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
With reference to embodiment and accompanying drawing, the utility model is described in further detail, but reality of the present utility model
Apply mode not limited to this.
Embodiment
As shown in figure 1, a kind of visual projection's interactive system based on pattern-recognition, including it is projecting apparatus 1, camera 2, infrared
Pipe 3 and PC；The camera 2 is fixed on support, and support vertical is fixed on level ground, and infrared tube 3 is arranged on support
Bottom, support behind installation projecting apparatus 1, be connected higher than camera and with PC, and be projected in the display picture of PC
View field is formed between user and camera, user is when using the system, system-oriented device, tiptoe pointing system
Position where device, effective foot's hot spot can be produced under the searchlighting of active light source, and be imaged in camera.
Infrared tube is specially word line infrared tube in the present embodiment, and infrared filter disc is set after the camera lens of camera, with drop
Low background complexity and prominent target hot spot.
System forms the plane of a near-infrared light source covering, when user moves in region, its pin in view field
Portion will produce diffusing reflection hot spot.Meanwhile cam lens add infrared fileter to reduce background complexity and prominent target light
Spot；Secondly, the Morphologic Parameters such as area, area girth ratio and circularity by calculating human foot's infrared light spot are simultaneously filtered
Ripple, form first order coarseness grader；Then, the minimal error rate Bayesian Decision in use pattern recognition methods is as two
Level fine grit classification device.Finally, the target article coordinate on image is mapped to the mouse coordinates of PC, and then realized to mouse
Control, reach the purpose of user and system interaction.
Above-described embodiment is the preferable embodiment of the utility model, but embodiment of the present utility model is not by described
The limitation of embodiment, it is other it is any without departing from Spirit Essence of the present utility model with made under principle change, modify, replace
Generation, combination, simplify, should be equivalent substitute mode, be included within the scope of protection of the utility model.
