Description
Technical field
The utility model relates to show equipment technical field of touch control, specifically, being related to a kind of contactless virtual touch-control
Device.
Background technique
Interactive physical touch screen (Touch Screen) is aobvious as long as user can be allowed lightly to touch computer with finger
Icon or text in display screen can be achieved with getting rid of keyboard and mouse action in this way to host service function, make human-computer interaction more
It is convenient.With advances in technology and develop, interactive touch-control screen is in the information inquiry of public place hall, e-commerce, movement
The regions such as office are widely used.
However, the interactive touch-control equipment under the above-mentioned this prior art, it is desirable that operator passes through directly touching screen
Scene plot face is to complete the operation to host.But with the requirements at the higher level that the innovation of technology and life requirement propose, many emerging
Application scenarios under, operator cannot achieve directly to be contacted with this interactive physical touch screen completion in the prior art.
For example, user needs the xegregating units such as wearing gloves in an aseptic environment, or user needs to wear in the case of bad weather
Wear safeguard, it is clear that the physics touch screen under traditional technology is unable to satisfy in the case of the new technologies and methods of such as above situation
Use demand.Obviously, the above deficiencies in the existing technologies propose new demand to non-contact gesture interaction.
Contactless interaction, which refers to, completes estimated operation after user is interacted using indirect mode with screen generation.Existing
In technology, it is real that contactless interaction is typically based on the equipment such as the Kinect of Microsoft or the realsense of Intel company
It is existing, it is using being installed on the camera of aspect phase user on screen perhaps gesture or movement of the depth camera to user
Interaction is captured, and by the position of the gesture of positioning user perhaps movement to identify hand-type or action, then will be known
Not Chu hand-type or movement posture with the preset operating gesture that is stored in equipment or movement carry out matching inquiry,
And query result is transmitted to terminal, and terminal is operated according to the instruction of instruction results pointer.
However, in actual use, it is clear that it is above-mentioned it is this to gesture and movement captured again with pre-stored hand
The efficiency for the contactless interactive mode that gesture data and action data carry out match query can not show a candle to the interactive mode directly contacted；
On the other hand, the process that gesture or action data and match query is stored in advance is also required to that special software is in addition arranged
Interaction driving engine, this virtually increases equipment cost again.One kind is had also been proposed in the prior art in operator and physics
Some plane for being parallel to the physical screen between screen is calculated as virtual touch surface by the three-dimensional perception of camera
Method judges whether the finger of user or limb part pass through the corresponding position of the virtual touch surface, then sends to computer
The touch control operation signal of corresponding position, to realize through the virtual touch surface of touch-control to realize the operation to computer.But this
Kind mode is limited due to being limited to camera shooting visual angle, usually cannot achieve reflecting to positions one to one all in larger screen
It penetrates；Either, in order to realize when screen is larger, one to one mapping to positions all on screen, then needing will be described
Virtual touch surface setting is apart from screen remote position, and this aspect makes operating effect sharp fall, and due to
Position apart from screen farther out, is also difficult to ensure the precision of position positioning.
For example, propose a kind of electronic whiteboard technology in the prior art, be using Infrared laser emission device, parallel and
Laser light curtain is projected with the position that screen or projected picture fit closely, then uses the sensing camera of infrared filter in a spacing
From outer photographed screen picture.When laser light curtain is not blocked, due to the bandha of laser, sensing camera will not take bright
Aobvious laser signal, and when laser light curtain by for example the modes such as user's finger touch screen are blocked when, laser light curtain is radiated at finger etc.
It is reflected on shelter, then emits and form bright hot spot in shooting picture to the laser in sensing camera direction, pass through knowledge
The position of other hot spot and size can be mapped as the touching signals of corresponding position on corresponding screen-picture, realize to calculating
The control of machine.
Although above-mentioned this electronic whiteboard technology solves the problems, such as that virtual touch-control is realized to computer operation,
It is corresponding accurate to need to keep one to one position of the virtual Touch Screen of laser and real screen again during realization, or even requires
The sensing region that the two carries out sensing camera in the case where approximate overlapping is demarcated, when cannot achieve the two approximation overlapping,
It will be unable to guarantee the precision of touch-control coordinate conversion.However, being actually used even if ensure that the approximate overlapping of the two in positioning
In the process, easily because by external force or needing the reasons such as adjustment that opposite position occurs between camera and virtual touch surface
It moves, or cannot keep touch surface always with real screen keeping parallelism, and these factors all will lead to the equipment and use
The precision of touching signals is influenced in journey.In the scene for needing to carry out non-contact touch-control control, virtual screen is close with real screen
Like overlapping, it will lead to finger and accidentally contact real screen, therefore also wish to virtual screen and real screen holding one is opposite
Biggish distance is to prevent from contacting.
In view of this, should be improved to the prior art, to solve the above-mentioned technical problems in the prior art.
