Abstract
The invention discloses hundred million pixel web cameras, belong to image processing technique field, this hundred million pixel web camera uses n (n>=the cmos image sensor that 10) individual process is arranged obtains vision signal.N video signal transmission after compressed coding, then is uploaded on Baidu's application engine server to H.265 coding processing device, and video-splicing is then carried out on that server, synthesizes hundred million pixel videos, and finally hundred million pixel videos for synthesizing are stored in NVR.The present invention is the target by carrying out the form of software splicing to vision signal to reach hundred million pixels.
Description
Technical field
It is research object with hundred million pixel web cameras the present invention relates to image processing field, proposes on this basis
A kind of method of hundred million pixel videos to vision signal through being spliced to form.
Background technology
Present requirement more and more higher of the people to video pixel, mega pixel can not meet the visual demand of people
, in order to improve the concept that this present situation puts forward hundred million pixels.The video of hundred million pixels becomes apparent from, and is drawn when wide-long shot
Matter also can more high-quality.In order to see hundred million pixel videos, a kind of method that can make equivalent hundred million pixel video is now needed.
The content of the invention
For above mentioned problem, the present invention proposes the thought that a kind of multiple vision signals of acquisition reach hundred million pixels after splicing
(overall construction drawing is shown in Figure of description 1).Mainly employ LVDS transmission technologys, software splicing.Hardware components include mirror
Head, H.265 cmos image sensor, coding processing device, BAE servers, NVR memories.Wherein BAE servers are software splicings
Platform.Cmos image sensor amounts to and is provided with n, and the row such as row such as n cmos image sensor are arranged in camera lens, by arranging
Cmos image sensor after cloth is used to gather and obtain video data.H.265 the quantity of coding processing device is also n, each
H.265 coding processing device is connected with cmos image sensor respectively；The data that cmos image sensor is obtained pass through LVDS technologies
It is sent in H.265 coding processing device, then coding is compressed to vision signal, then the video flowing after coding is uploaded to and is drawn
Hold up carries out splicing and is synthetically formed hundred million pixel videos on server i.e. BAE servers, finally arrives hundred million complete pixel video storages
In NVR memories.When needing to pay a return visit, download, decompress, decode.
The technical solution adopted in the present invention is：This product mainly proposes a kind of structure of hundred million pixels web camera,
Including gathered data, processing data, data storage.This hundred million pixel web camera uses n (n>=10) it is individual by arrangement
Cmos image sensor obtains vision signal, here the main COMS imageing sensors from 16,000,000 pixels, data flow have n ×
16×16××30bit/s.The n vision signal that will be obtained is transferred in H.265 coding processing device using LVDs transmission technologys
Coding is compressed, H.265 the compression ratio of coding processing device can reach 200:1, the data flow after compression be n × 384 ×
bit/s.Cmos image sensor is transmitted with H.265 encoder using CSI-2 interfaces.Then by n video after compressed encoding
Data upload to Internet by gigabit LAN, then (BAE is serviced by gigabit wide area network transmission to application engine server
Device) on, to n video data uncompressed encoding, n data after treatment are stitched together, synthesize a hundred million complete pixels
Video, the vision signal of synthesis probably has n × 16 × individual pixel.Finally hundred million pixel videos for synthesizing are stored in NVR.
The LVDS transmission technologys, for the transmission of video signal flow.
The software splicing, splicing synthesis is carried out in application engine to multi beam video flowing.
The camera lens, for autozoom.
The cmos image sensor, for obtaining vision signal.
H.265 the coding processing device (Hi3519 chips), for being encoded to video signal compression, using H.265 encoding
Principle.
The BAE servers, for video software splicing.
The NVR memories, hundred million pixel videos for depositing synthesis.
The workflow of the hundred million pixels web camera is comprised the following steps：
Step 1：Cmos image sensor gathers vision signal.
Step 2：Vision signal to collecting is compressed coding.
Step 3：Vision signal after being encoded to n carries out software splicing.
Step 4：Hundred million pixel videos that will synthesize are stored in NVR.
Compared with prior art, the present invention has the advantages that：1st, in order to solve what web camera was shot
The low problem of video pixel.2nd, this product reaches the effect of hundred million pixels using the thought of video-splicing.
Brief description of the drawings
Fig. 1：Overall construction drawing (n>=10).
Fig. 2：16 arrangements of cmos image sensor.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
What is selected in the present invention is that the cmos image inductor of 16 16,000,000 pixels carries out video acquisition, 16 CMOS figures
As the data flow of inductor probably has 16 × 16 × 16 ×× 30bit/s.In order to expand shooting visual angle, can on the image sensor
Addition camera lens.The data volume of video flowing is excessive, so coding will be compressed to the vision signal for gathering, is chosen in the present invention
This chip of Hi3519 processes vision signal, there is H.265 encoder on Hi3519 chips, and maximum can support 16,000,000 pixels
Cmos image sensor, the compression ratio of chip can reach 200:1 high compression rate.This new cryptoprinciple uses advanced
Technology be used to improve relation between code stream, coding quality, time delay and algorithm complex, being optimal is set.After compression
Data flow probably have 16 × 384 × bit/s.Vision signal after treatment uploads Baidu's application engine server (BAE services
Device) on carry out software splicing, to 16 video data uncompressed encodings, treatment after 16 data be stitched together, synthesis one
Individual hundred million complete pixel videos, finally by the storage of hundred million pixel videos in NVR memories.
