Brief description of the drawings
Fig. 1 is the flow chart of the VR three-dimensional experiencing systems of gesture identification.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Referring to Fig. 1, in the utility model embodiment, a kind of VR three-dimensional experiencing systems of gesture identification, including ray connect
Device unit, gesture original state unit and gesture positioning unit are received, wherein gesture positioning unit includes gesture information collection and divided
Unit and identification and the applying unit of gesture are analysed, the ray receiver unit includes ray receiver, and ray receiver is used for
Receive the VR heads that user uses and show equipment and gesture equipment；The gesture information collection includes project structured light with analytic unit
Device, light time-of-flight sensor and polygonal imaging camera head；The structured light projector uses laser projecting apparatus, project structured light
Device is externally provided with a grating for being carved with certain patterns, and laser can reflect when carrying out projection imaging by grating, so that
The final drop point on a surface of an of laser produces displacement, when object distance laser projecting apparatus is closer, refraction and produced
Raw displacement is with regard to small；When object distance farther out when, refraction and caused displacement also will become big accordingly；The gesture information is adopted
The pattern collection that collection also includes projecting pattern on body surface for detecting collection structured light projector with analytic unit images
Head, pattern acquisition camera are gathered by the detection to pattern change in displacement, and position and the depth of object are calculated using algorithm
Information is spent, and then restores whole three dimensions；The smooth time-of-flight sensor includes light-emitting component and COMS imaging sensors,
COMS imaging sensors are used for catching the photon for being sent by light-emitting component and being reflected from body surface, so as to obtain photon
Flight time, according to photon flight time and then the distance of photon flight can be extrapolated, also just obtained the depth of object
Information；The quantity at least two of the polygonal imaging camera head, image is absorbed simultaneously using at least two cameras, passes through ratio
The difference of the image obtained to these different cameras in synchronization, depth information is calculated using algorithm, so as to polygonal three
Dimension imaging；The gesture original state unit, can be self-defined initial according to user's needs primarily to distinguish gesture motion
State, use family more comfortable；The gesture information collection and analytic unit, utilize user by ray receiver
