Description
Technical field
It the utility model is related to augmented reality field, more particularly to a kind of interactive projection system.
Background technology
At present, various abundant in content children's class TV programme enrich the playtime of children, are brought to numerous children
Joy.In fact, at present for children, maximum amusement is exactly to see TV；And various game are then not appropriate for, this is
Because game needs complicated operation, even some simple trivial games are also required to the children at larger age（Such as 6 one full year of life with
On）Just it is understood that and plays.But game can meet the entertainment requirements of children with well interactive.Therefore, at present
There is the unfavorable condition that some children indulge in game, cause the heightened concern of parent.
On the other hand, with the development of science and technology there is augmented reality, it is a kind of by real world information and void
Intend " seamless " the integrated new technology of world information, it script in the certain time spatial dimension of real world is difficult to experience to be
Entity information (visual information, sound, taste, tactile etc.) by science and technology such as computers, be superimposed again after analog simulation, by void
The Information application of plan is perceived, so as to reach the sensory experience of exceeding reality to real world by human sensory.Real environment
It has been added to and same picture or space while has existed in real time with virtual object.
How a kind of interactive projection system based on augmented reality is provided, is prevented when children carry out real-time interactive because of human body
Block and occur the shadow on screen, lift display effect, be research topic of the present utility model.
The content of the invention
Goal of the invention of the present utility model is to provide a kind of interactive projection system.
To achieve the above object of the invention, the technical solution adopted in the utility model is：A kind of interactive projection system, it includes
Main control computer, the projecting apparatus being connected with main control computer and be arranged in front of projecting apparatus and with the matching used throwing of projecting apparatus
Shadow screen, the angle of plane where the projecting apparatus and line and projection screen of the projection screen bottom on perpendicular is 0 ~
30 °, the distance of plane is 1 ~ 1.6m where the projecting apparatus to projection screen；
The projecting apparatus is wide angle projection instrument, and the wide angle projection instrument includes projection chip and wide angle projection lens, described
The focal length projection ratio of wide angle projection lens is less than 0.6, and the wide angle projection lens include the set gradually along projecting direction
One lens group, the second lens group, diaphragm and the 3rd lens group.
Above, it is not specifically limited for the number of degrees of angle, the utility model, it is typical but non-limiting to be
0°、1°、3°、5°、10°、15°、20°、25°、27°、29°、30°.It is preferred that 20 ~ 25 °.
Distance for the projecting apparatus to plane where projection screen, the utility model are not specifically limited, typical case but
It is nonrestrictive can be 1m, 1.05m, 1.1m, 1.15m, 1.2m, 1.25m, 1.3m, 1.35m, 1.4m, 1.45m, 1.5m,
1.55m、1.6m.It is preferred that 1.3m.
Preferably, connected between the main control computer and projecting apparatus by HDMI.
Further, the projecting apparatus is fixed on the movable end of a telescoping shoring column, the elongation of the telescoping shoring column
Direction is consistent with the exit direction of projecting apparatus.
Preferably, the fixing end of the telescoping shoring column is fixed on the ceiling, and now, projecting apparatus is suspended in ceiling
On.
Preferably, the projecting apparatus is wide angle projection instrument.
Because above-mentioned technical proposal is used, the utility model has following advantages compared with prior art：
1. the utility model can effectively prevent children from projecting by setting the relative position of projecting apparatus and projection screen
The light path of projecting apparatus injection is blocked when being operated on screen, avoids occurring the shadow on the projection screen, lifts display effect；
2. the utility model fixes projecting apparatus using telescoping shoring column, be easy to adjust according to actual needs projecting apparatus with
The angle of plane where line and projection screen of the projection screen bottom on perpendicular, so as to meet different height children's
Use demand, it is applied widely；
3. the utility model is simple in construction, easy to use, suitable for popularization and application.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment one.
Wherein：1st, projecting apparatus；2nd, projection screen；3rd, telescoping shoring column.
Embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model：
Embodiment one：
Shown in Figure 1, a kind of interactive projection system, it includes main control computer, the projection being connected with main control computer
Instrument 1 and it is arranged in front of projecting apparatus and projection screen matching used with projecting apparatus 2, the projecting apparatus and projection screen bottom
The angle of plane is 0 ~ 30 ° where line and projection screen on perpendicular, flat where the projecting apparatus to projection screen
The distance in face is 1 ~ 1.6m；
The projecting apparatus is wide angle projection instrument, and the wide angle projection instrument includes projection chip and wide angle projection lens, described
The focal length projection ratio of wide angle projection lens is less than 0.6, and the wide angle projection lens include the set gradually along projecting direction
