Description
Technical field
The present invention relates to a kind of multimedia interaction optical projection system, and in particular to a kind of signal of multimedia interaction optical projection system
Emitter.
Background technology
Multimedia interaction optical projection system is based on motion tracking technology, by the action of interactive participant and the image projected
The multimedia technology of interaction feedback.Existing multimedia interaction optical projection system generally includes image-forming module, signal emission module, letter
Number acquisition module, signal processing module composition.
Image projecting, is typically presented on specific position, example by image-forming module using projector or other picture reproducers
Such as metope, curtain surface, glass panel position, picture reproducer in addition to projector, plasma display, liquid crystal display,
LED screen can serve as the carrier of interactive image；
Signal emission module, typically using infrared transmitter, an infrared-ray face is got in the covering of image position of appearing（No
Visible ray）, when the body part of interactive participant is acted close to image, it can stop, interrupt infrared-ray, it is red during stop
Outer ray can produce a luminous point；
Signal acquisition module, seizure shooting is carried out according to interactive demand, typically catches interactive participant using infrared camera
The luminous point produced is acted, coordinate data is produced, feeds back to signal processing module；
Signal processing module, typically using the coordinate data of computer and computer software according to luminous point, at image
Reason, then feeds back to image-forming module, it is projected out corresponding image, completes interactive process.
The problem of it is present is that existing multimedia interaction optical projection system is typically to fix infrared transmitter operationally
Set, therefore infrared-ray is distributed by a fixed point, when interactive participant's body part is operated close to image, this
Luminous point should be produced at concrete operations position（Such as finger position）, but other positions of body be likely to be at finger with it is infrared
Between transmitter, as a result contact earlier, stop infrared-ray produce the luminous point coordinate data of mistake, have impact on multimedia mutual
The accuracy of dynamic optical projection system, and perspective plane always belongs to unlike material, and simple fixed form easily causes infrared emission
The situation that device comes off, if perspective plane has rough situation, the infrared transmitter being simply fixedly installed is in depression
Perspective plane can not just be completely covered if place.
The content of the invention
The present invention believes to solve not enough can be adjusted in multimedia interaction optical projection system there is provided one kind of above-mentioned technology
