Description
Technical field
The present invention relates to a kind of video image interactive system, be widely used in educational training, advertisement media, commercial entertainment,
Medical treatment etc..
Background technique
Usual exchange method is all to interact process by means of handheld device or specified medium in existing technology,
Such as Chinese patent, the patent No.: denomination of invention: ZL200510100240 computer projection auxiliary positioning method and uses this method
Interactive demonstration system, in mention further include electronic pen, which includes several circuit switches and is arranged on its circuit
Electromagnetism wave oscillator, when circuit switch conducting, the frequency of electromagnetic wave which generates changes；When this
When electronic pen issues electromagnetic wave to a certain position of the blank, which can incude the electromagnetic wave and carry out coordinate setting, and can incite somebody to action
The positioning coordinate is transferred to computer.For another example Chinese patent, the patent No.: ZL200810241540.3, denomination of invention: one kind has
The optical projection system of interactive function, in mention the sensing pen that the interactive special pens are built-in sensors and transmit circuit.In large size
In place, be especially adaptable to business and advertising of show business etc., interactive system cross control advertising results be by with
The interaction of passerby or spectators realizes, but both the above method equipment limit user can only wear or Portable device could be with
Equipment interaction, use is very inconvenient, and in the presence of structure is complicated, part processing difficulties, and adjustment is time-consuming and laborious, and working efficiency is low,
The technical problems such as inconvenient for use.
Summary of the invention
The object of the present invention is to provide a kind of video image interactive systems.
The technical scheme is that video image interactive system, including transmitting light source, it is sent out for being exported to delimited area
Penetrate light；
Inductor for acquiring the reflection of transmitting light, and obtains movement or position consecutive image of the object in institute's delimited area；
Processor module, for obtaining the two dimension of object outline by obtaining image difference to two frames analysis before and after consecutive image
Data coordinates obtain object outline by 2-D data coordinate analysis, by judge object outline moving direction or locating position
It sets, to determine the variation of interactive image；
Image display, for the variation according to interactive image, output display picture.
Further, the transmitting light source is infrared light supply.
Further, the inductor is ccd sensor.
Further, the image display is projector or one or more of TV or display.
The advantages and positive effects of the present invention are: directly realizing and interacting by the movement of moving object or state
The interaction of system does not have to enable interactive system being suitable for broader range by any auxiliary tool.
Detailed description of the invention
