Embodiment
The embodiment of the high in the clouds high-definition image processing platform of the present invention is described in detail below with reference to accompanying drawings.
Cloud computing, i.e. cloud computing, are the increase, use and delivery mode of the related service based on internet,
It is usually directed to by internet to provide dynamic easily extension and the often resource of virtualization.Cloud is one kind of network, internet
Liken saying.Past often represents telecommunications network in figure with cloud, is also used for representing internet and underlying infrastructure later
It is abstract.Therefore, cloud computing even can allow you to experience the operational capability of 10 TFlops per second, possess so powerful computing capability
Can be with simulated-nuclear explosion, Prediction of Climate Change and market trend.User is accessed by modes such as computer, notebook, mobile phones
Data center, computing is carried out by the demand of oneself.
There are a variety of sayings to the definition of cloud computing.For on earth what be cloud computing, can at least find 100 kinds of explanations.
Well accepted at this stage is National Institute of Standards and Technology (NIST) definition:Cloud computing is that one kind is paid by usage amount
Pattern, this pattern provides network access available, easily, on demand, into configurable computing resources shared pool (money
Source includes network, server, storage, application software, service), these resources can be provided quickly, only need to put into seldom pipe
Science and engineering is made, or carries out seldom interact with service supplier.
Piracy, which is taken on the sly, to be typically occurred in cinema, theater, arenas, projection room or theatre, and operator is in order to avoid steathily
Bat behavior it is prevailing, it will usually arrange special staff to be arranged in around auditorium, every fixed intervals arrange one,
With the manner behavior of spectators near naked-eye observation, once the recording that finds to there is spectators' hand-held mobile terminal to carry out image or photo
Shooting, is gone forward to prevent immediately or is alerted using hand-held infrared emission pen, so as to interrupt the behavior of taking on the sly of spectators.
However, there is the drawbacks of inherent in this artificial anti-mode taken on the sly:First, if auditorium area is larger, need
Many staff are arranged to carry out field monitor, it means that to need substantial amounts of cost of labor;Secondly, staff's naked eyes are swept
The mode efficiency retouched is low, and the mode of direct surveillance easily occurs to let off taking on the sly for some corner locations because of burnout
Person;Finally, set the mode of staff to bring discomfort to the spectators of normal viewing performance near spectators, it is glad to have impact on them
Appreciate the mood of performance.
As can be seen here, the artificial anti-mode taken on the sly has inborn deficiency, in order to overcome above-mentioned drawback, reduces and prevents what is taken on the sly
Operation cost, the anti-operating efficiency taken on the sly is improved, operator always searches for the anti-mode taken on the sly of electronics and carries out on-site supervision, electricity
Anti- take on the sly of son has two kinds of developing direction, and a kind of made an issue of on the mobile terminal held in spectators, when mobile terminal is shot certainly
Dynamic detection is taken on the sly behavior, but this mode may be because that the person of taking on the sly is avoided to the selection of mobile terminal, another kind be
The scene of taking on the sly disposes electronic jamming device, and this mode can avoid evading for the person of taking on the sly.
The existing anti-electronic jamming device taken on the sly is that a kind of infrared facility is placed in the back side of curtain or stage,
Infrared facility sends the sightless infrared ray of human eye, infrared if the person of taking on the sly is moving terminal or video camera shooting
Line will disturb the video camera imaging of the person of taking on the sly, the image or lower picture quality for causing the person of taking on the sly to obtain, can not commercially sell
Sell and propagated on network, so as to effectively safeguard copyright interest.
But this mode needs to launch infrared ray always, and the transmitting of infrared ray is large-scale, it is necessary to from each
Infrared ray is all launched in position, and cost is higher and poor feasibility.Therefore the anti-equipment of taking on the sly of the electronics at scene also needs to find others
Break through direction.
In order to overcome above-mentioned deficiency, the present invention has built a kind of high in the clouds high-definition image processing platform, can be by scene
The behavioral value of spectators and determine to whether there is in audience seat by the parameter extraction to site environment in auditorium
The person of taking on the sly, and the position where the person of taking on the sly can be positioned in time, in order to take corresponding orientation warning measure, remind
The person of taking on the sly abandons the behavior of taking on the sly

In addition, CPLD (Complex Programmable Logic Device) CPLD, be from
The device that PAL and GAL device developments come out, comparatively scale is big, complicated, belongs to large scale integrated circuit scope.It is
A kind of user according to respective need and voluntarily digital integrated electronic circuit of constitutive logic function.Its basic design method is by integrated
Develop software platform, the methods of with schematic diagram, hardware description language, generate corresponding file destination, by download cable ("
System " programs) code is sent in objective chip, realize the digital display circuit of design.
CPLD is mainly the programmable interconnection matrix list that center is surrounded by FPGA macroelement (MC, Macro Cell)
Member composition.Wherein MC structures are more complicated, and with complicated I/O cell interconnection structures, can be generated as needed by user specific
Circuit structure, complete certain function.Because the metal wire inside CPLD using regular length carries out the interconnection of each logical block,
So the logic circuit of design has time predictability, the shortcomings that segmented interconnection structure sequential is not exclusively predicted is avoided.
From CPLD developing histories, in the 1970s, earliest PLD -- PLD is born.Its
Export structure is programmable logic macrocell, because his Design of Hardware Architecture can be completed (to cover equivalent to house by software
Artificial portion of design bureau doors structure afterwards), thus his design has very strong flexibility, but its mistake than the digital circuit of pure hardware
Them are also made to realize the circuit of scale is smaller in simple structure.For make up PLD can only design small scale in circuitry this lack
Fall into, the 1980s mid-term, be proposed CPLD -- CPLD.This application goed deep into network, instrument and meter,
Automotive electronics, Digit Control Machine Tool, Space TT&C system etc..
CPLD has the characteristics that:With flexible in programming, integrated level is high, designs and develops that the cycle is short, the scope of application is wide, exploitation
Instrument is advanced, design and manufacture cost is low, standardized product low to the hardware skill requirement of designer is without test, strong security, valency
The features such as lattice are popular, fairly large circuit design can be achieved, therefore be widely used in the prototype and product of product
Among production is (typically below 10,000).Nearly all occasion using middle and small scale general digital integrated circuit can be answered
With CPLD devices.CPLD devices turn into the indispensable part of electronic product, and its design and application turns into electronics work
A kind of journey Shi Bibei technical ability.
