Description
Technical field
The present invention relates to a kind of interactive exhibition system, method and the dresses of the augmented reality for popular science propaganda education sector
It puts.
Background technology
In recent years, in display and demonstration project, such a deduction mode, the basic displaying side of this mode are frequently seen
Method is interacted using a perspective plane horizontally or vertically and visitor or user.It is this virtual existing based on enhancing
Real interactive display mode, is highly suitable for popular science propaganda education.In order to realize this exhibition method interacted, in technology
On can have more mature following several implementation methods.
A kind of realization technology is based on camera infrared imaging analytical technology.Infrared imaging pattern is common technology,
Principle is：Using invisible infrared light-illuminating interaction area, one layer of infrared external reflection face is formed, is handled using by infrared filtering
Camera by interaction personnel block after image analyze and process.Newest analytical technology is the height based on OpenCV technologies
Fast image analysis method.The shadow positions in the infrared external reflection face image through blocking are obtained using this as interaction trigger position, and
By two-dimensional coordinate pass to interactive software system, by backstage interactive managing system for interaction two-dimensional coordinate make feedback,
Corresponding image is rendered by rendering system and interacts displaying.
The advantage of infrared imaging analytical technology is that its implementation cost is relatively low, and interactive device only needs infrared lamp and by red
The common CCTV video cameras of the outer transformation that filters, the image capture interface and related software being fitted in PC machine, you can implement.
The interactive device expense of every square metre of interactive region is in thousand yuans of ranks.And the disadvantage is that, due to video camera shooting and
Infrared lamp irradiating angle problem, the resolution ratio for causing device is relatively low, and larger shield can only be fed back.Meanwhile by
In the image recognition analysis for needing progress intensive, so interaction delay is more serious.
Another is achieved in that based on infrared two-way emission type interaction technique.Infrared two-way emission type interaction technique be also one into
Ripe technology, originating from infrared two-way emission type sensor, originally applied to industrial detection.In the development of multimedia interactive demand
In, infrared two-way emission type interactive device is technically simple, cheap (relative to capacitance interactive mode, plasma interactive mode with its
With sound wave interactive mode) the features such as once once occupying more than 90% share in touch screen interaction market.The full name of its technology is called
" active infrared line blocks detection ", basic construction includes transmitting terminal, receiving terminal, beam intensity control, optical lens etc..It is former
Reason is using the infrared-ray of infrared light-emitting diode transmitting, does focusing using optical lens, reaches light far
Distance, last light are received by the photistor of receiving terminal.When there is the infrared-ray that object blocks transmitting terminal transmitting, due to
Receiving terminal can not receive infrared ray, so trigger signal can be sent out.Infrared ray is a kind of black light, and can be spread, and is thrown
After being shot out, cone light beam can be formed in starting pipeline stage, with the increase of transmitting range, ideal tensile strength and transmitting
Distance decays in inverse square.When object crosses its search coverage, interdict infrared beam and cause trigger signal.Infrared touch panel
Whether gather X, the infrared ray matrix in Y-direction exactly before screen is close to, have infrared ray to be hindered by object by ceaselessly scanning
Gear detects and positions the touch of user.And the X that is blocked according to infrared ray, the position in Y-direction export corresponding two-dimensional coordinate,
And by two-dimensional coordinate pass to interactive software system, by backstage interactive managing system for interaction two-dimensional coordinate make instead
Feedback, renders corresponding image by rendering system and interacts displaying.Similar technology also has sound wave detection to be blocked to hand over to penetrating
Mutual mode and plasma ray block detection interaction technique, carry out the analysis of advantage and disadvantage together herein, just no longer repeat.
The advantage of infrared two-way emission type interaction technique is, for smaller display surface, resolution ratio is relatively
High, resolution ratio can reach the interaction resolution of 4096*4096DPI.Its stability is also relatively high, due to its main group
Into being partly infrared diode and photo resistance, industrialization degree is higher so that its stability has also reached higher level.
In addition, the capital equipment service life due to this scheme depends on the service life of infrared light-emitting diode, this also just imparts this kind of friendship
Mutual device has the long-life, high durable, not by the characteristic of electrical Interference.The prime weakness of which is, due to such scheme
The blocking test of various media is used to realize interactive coordinate judgement, also just can accordingly have erroneous judgement to similar substance
Property, that is, there is weak resistance for strong light there are infrared equipment, acoustic wave device has strong noise weak resistance etc., thus limits
The use scope of this kind equipment.Secondly because this kind of two-dimensional coordinate positioning device sensing range size is exactly detect matrix big
It is small, when needing to expand perception interactive range, it can only simply increase the size of detection matrix, in large size interaction project
In, according to square calculate in the case of, expense will be excessive, and every square metre of cost of this class interactive device reaches ten thousand yuans
More than, and since the installation of device comes to the surface, need mounted on the upper strata of interaction content, and be symmetrical line formula
, the shape-designing for causing interaction content is difficult.
The third mode is laser radar positioning interaction mode.Laser radar is operated in infrared and visible light wave range, with
Laser is working beam.It is made of laser transmitter, optical receiver, turntable and information processing system etc., and laser will be electric
Pulse becomes light pulse emission and goes out, and optical receiver electric pulse is reduced into from the reflected light pulse of target, is sent to again
Computing device.The effect of laser radar be can accurately measure target location (distance and angle), motion state (speed, vibration and
Posture) and shape, detection, identification, resolution and tracking target.Laser radar uses 2 kinds of working methods of pulse or continuous wave, detection
Method can be divided into Mie scattering, Rayleigh scattering, Raman scattering, Brillouin scattering, fluorescence, Doppler according to the principle difference of detection
Wait laser radars.Laser radar is the radar system to emit the characteristic quantities such as the position of detecting laser beam target, speed.From work
Say there is no basic difference with microwave radar in principle：To objective emission detectable signal (laser beam), then will receive from
The reflected signal of target (target echo) is compared with transmitting signal, after making proper treatment, so that it may which obtain target has
Close information, such as target range, orientation, height, speed, even posture, shape parameter.In interaction schemes, laser radar
Effect is to form a piece of laser scanning light curtain apart from interaction face 2mm-10mm or so in interaction surface, by being moved in light curtain
The position of interaction body and finding out for motion state, the two-dimensional coordinate relative to laser emission point is formed, to reach interactive work
With.The advantages of radar is that small, light weight, sensing area are big, cheap.
But the defects of laser radar is also that obviously, first, when work is big by environment and atmospheric effect.Laser
Generally decay in bright day gas smaller, propagation distance is farther out.And in the bad weather such as humidity, dense smoke, thick fog, attenuation is drastically
It increases, propagation distance is greatly affected.If operation wavelength is 10.6 μm of co2 laser, be in all laser propagation in atmosphere performance compared with
Alright, in the attenuation of bad weather it is 6 times of fine day.Moreover, air circulation can also make laser beam be distorted, shake, directly
Influence the measurement accuracy of laser radar.And its precision is relatively low, its resolution ratio can only achieve a centimetre rank, institute under normal circumstances
This kind equipment can not be used in fine interaction demand.
4th kind of mode is nanometer conductive ink interactive mode.Nanometer conductive ink interactive mode is just to rise for 2017
A kind of new media interactive mode with artistic feeling, principle are the conductive characteristics using nanometer-level silver and graphite material, are passed through
Human contact generates short circuit current, to excite corresponding interactive action.The original exploitation purposes of this nano material is to be applied to
The circuit printing technology of fine-grade can carry out the printing of circuit on multiple material by printer, and this makes it possible to significantly
It reduces the preparation process cost of circuit or even by improving the printings of specialized printers rate respectively, circuit is prepared into grade easily
Ground is promoted to Nano grade.Certain European new media company in 2017 be proposed in exhibition with printing of conductive inks into exhibition
, by human body touch, short circuit current is formed, to excite corresponding projection image, the bandwagon effect of augmented reality is formed, from this
Nanometer conductive ink interactive mode enters interactive display industry.
The advantages of nanometer conductive ink mode is to implement simply, it is only necessary to carry out computer drawing, and root to displaying pattern
The circuit that intermittent is carried out according to the situation of touch patterns needed for displaying interaction is set, then directly can large area by printer
Printing is implemented, then passes through conducting resin adhesion node to signal collection device, you can implements the confirmation of interaction locations, is handed over so as to generate
Mutual effect.And since the printing material of conductive ink can be flexible material, so conductive ink interactive mode has front 3
In mode the interaction of impossible curved surface realization, provide the design space of bigger and aobvious for the Project design in displaying
Existing mode.
The defects of conductive ink is maximum is, must be prefabricated.Need to carry out at the scene if piecemeal prints compared with
Work is bonded for accurate circuit.So at present, this kind of exhibition item is usually all to cut into smaller interactive block face, and according to friendship
What mutual block face interacted.Simultaneously because the problem of cost, in the more sparse large-scale exhibition item of interaction block, this interaction side
Formula still there are implementation cost it is excessively high the problem of.
