When finger or other lighttight objects are intervened between the laser projection 1 and projected display region, and throwing
When having touch action operation on shadow image, the projected path that will lead to part black light structure light is hindered, relative to throwing
The projection for the black light structure light that shadow path is unimpeded can be in the intrusion object because of the convex-concave surface of intrusion object
Hinder position to generate the non-progressive or non-smooth imperceptible structured light deformation of apparent part, black light Image Acquisition
Device after the imperceptible structured light pattern for collecting the local deformation, is sent to intelligence system and carries out image procossing.Due to intrusion object
Intervention caused by local imperceptible structured light deform caused by otherness, be obvious and be easy to judge, thus can
Orient the specific touch location of the intrusion object.About the motion detection of finger or opaque object, using image difference
The technology of dividing, subtracts each other the imperceptible structured light pattern for the two continuous frames that black light image acquisition device obtains, analysis obtains
Be motion parts data.
The intelligence system is mounted in ultrashort burnt laser projection, on the one hand with the drive control of laser projection
System is connected, and laser projection is made to have intelligent operating system.On the other hand, it is connected with black light image acquisition device, energy
The collected imperceptible structured light pattern containing user's operation information is enough handled, and based on this pattern, in conjunction with intelligence
Image processing program in system, positions the touch location of user, to drive mouse mobile, completes shirtsleeve operation, reaches
To the operating effect of similar touch screen.
Man-machine interactive system process based on imperceptible structured light:
1) laser projection projects the pattern containing imperceptible structured light in the frame gap of projection normal visible light image,
User carries out touch action operation before projected image；
2) black light image acquisition device captures the imperceptible structured light pattern data containing user's operational motion, and will
The data are sent to intelligent operating system；
3) in intelligent operating system, imperceptible structured light pattern data is handled, the touch for finding out user is dynamic
Make, driving mouse is mobile, completes the operation of similar touch screen；
4) realize the combination of visible light live fluoroscopic images data in the touch action data and processor of user, i.e., it is complete
It is handled at user's movement and the synthesis docking of live fluoroscopic images, preparation throws real-time interaction effect in the form of visible light
Shadow is to projected display region.
Then, continue to project containing imperceptible structured light in the frame gap of projection visible images in laser projection
Pattern, black light image acquisition device prepare imperceptible structured light pattern data of the capture containing user's operational motion.
