Description

A kind of electronic eyes

Technical field

The present invention relates to electronic applications, refer to especially a kind of supervising device.

Background technology

Along with China's expanding economy, living standards of the people also improve day by day, and the family that has motor vehicle is more and more, and China has been global first automobile consumption state, and exceeding the U.S. becomes global first automobile to possess state be also within sight.

Motor vehicle is many, stops and becomes a difficult problem, and the present situation of China is that public parking resource is very limited, and especially city CBD stops and finds no parking space especially.Roadside arbitrarily parked by vehicle by a lot of drivers, makes originally more to block up with regard to narrow and small road.

For the roadside situation of arbitrarily stopping, main monitoring and managing method is to paste penalty note by traffic police at present, carries out economic penalties, but traffic police's police strength is limited, cannot follow the tracks of in the moment, more can each road manning, therefore, a lot of drivers entertain idea of leaving things to chance, and vehicle is arbitrarily stopped in roadside.

How prohibiting the phenomenon of stopping stopped in section by unrest and carry out timely, intelligentized management, is current problem demanding prompt solution.

Summary of the invention

The present invention proposes a kind of electronic eyes, has solved the problem of disorderly stopping in prior art.

Technical scheme of the present invention is achieved in that

A kind of electronic eyes, comprising:

Prohibit and stop Sign Board, its quantity is 2, is arranged on two ends, territory, prohibition parking area, and described taboo is stopped Sign Board camera is installed, and described camera surpasses to the setting of territory, prohibition parking area, and sampling interval is 1 minute;

Described taboo is stopped Sign Board and is also embedded with dsp chip, and dsp chip carries out format conversion to the picture signal of camera output, is converted to GIF form;

Image processing module, is connected to described dsp chip, and two of front and back picture signal is compared, and differential image signal is carried out to image processing, by the processing of car plate part sharpening;

GPRS module, sends to host computer processor by described package information.

Alternatively, described dsp chip is TMS320DM642 chip.

The invention has the beneficial effects as follows:

Stop the sampling of camera on Sign Board and prohibit the image that stops section by being arranged on to prohibit, former and later two images of comparison sampling, upload to host computer by GPRS module by differential image.

Brief description of the drawings

In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is the control block diagram of electronic eyes of the present invention.

Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.

As shown in Figure 1, a kind of electronic eyes of the present invention, comprising:

Prohibit and stop Sign Board, its quantity is 2, is arranged on two ends, territory, prohibition parking area, and described taboo is stopped Sign Board camera 30 is installed, and described camera surpasses to the setting of territory, prohibition parking area, and sampling interval is 1 minute; Described taboo is stopped Sign Board and is also embedded with dsp chip 31, and dsp chip carries out format conversion to the picture signal of camera output, is converted to GIF form; Image processing module 40, is connected to described dsp chip, and two of front and back picture signal is compared, and differential image signal is carried out to image processing, by the processing of car plate part sharpening; GPRS module 50, sends to host computer 60 processors by described package information.

Dsp chip carries out format conversion to the picture signal of camera output, is converted to GIF form, and the image volume of GIF form is little but degree of distortion is very low, and naked eyes are difficult to identification, meet the requirement of taking pictures.

Preferably, described dsp chip is TMS320DM642 chip.

TMS320DM642 is up-to-date fixed DSP in the C6000 of TI company series DSP, its core is C6416 type high-performance digital signal processor, there is extremely strong handling property, dirigibility and the programmability of height, equipment and the interfaces such as simultaneously peripheral integrated very complete audio frequency, video and network service.

TMS320DM642 chip comprises: 3 configurable video ports (VPORT0-2) can be realized seamless link with general video coding and decoding device, support various video resolution and video standard, support RAW video input/output, transport stream mode; 1 10/100Mb/s Ethernet interface (EMAC), meets IEEE802.3 standard; 1 hyperchannel band buffered audio serial port (McASP), supports I2S, DIT, S/PDIF, IEC60958-1, the audio formats such as AES-3, CP-430; 2 hyperchannel band buffering serial ports (McBSP), adopt RS232 level to drive; 1 VCXO interpolation control module (VIC), supports that audio/video is synchronous; 1 32,66M hertz, the master/slave pci interface of 3.3V, follow PCI2.2 specification; 1 configurable 16/32 host interface of user (HPI); 1 16 general input/output port (GPIO); 1 64 external memory interfaces (EMIF), can with most of asynchronous memories (SRAM, EPROM) and synchronous memories (SDRAM, SBSRAM, ZBT SRAM, FIFO) seamless link, maximum addressable external memory storage space is 1024MB; 1 has the enhancement mode direct memory access controller (EDMA) of 64 autonomous channels, tunnel; 1 data management input/output module (MDIO); 1 I2C bus module; 3 32 general purpose timers; 1 meets jtag interface and the daughter board interface etc. of IEEE1149.1 standard.

Electronic eyes of the present invention stops the sampling of camera on Sign Board and prohibits the image that stops section by being arranged on to prohibit, and former and later two images of comparison sampling, upload to host computer by GPRS module by differential image.
