Description
Technical field
The invention belongs to information data transmission technical fields, and in particular to a kind of high-speed video collecting and transmitting method.
Background technique
In some special occasions or certain special fields, needs using special high-speed camera shooting and recorded
Journey, such as: when fast-changing scenes such as the moments for shooting object explosion, need image data Long Distant Transmit to rear end
Receiving device carry out receive and data processing.The picture format of these high-speed cameras output is usually off-gauge, not
It is common SD, high definition or super clear reference format, can not be passed using common digital video transmitter, receiver
It is defeated.
When digital camera exports image, common interface form includes USB, 1394 (fire wire), GE
(Ethernet), LVDS, CameraLink etc..Wherein, USB interface is shown especially suitable for camera is directly connected to computer
Show, can support various resolution ratio and frame frequency, is usually used in various SD, high-definition camera.1394 interface transmission rates are high, occupy
Cpu resource is few, and the operation is stable is also widely used on digital camera.Gigabit Ethernet (GE) transmission rate is high, price
It is cheap, it is used in various resolution ratio and frame frequency.CameraLink interface is a kind of bus type most fast in current industrial camera
Type is generally used on high-resolution high-speed area array camera or line-scan digital camera.
USB2.0 interface rate is lower, and CPU participative management is needed in transmission process, occupies and consumption resource is larger, pass
Defeated distance is close, and signal is easy decaying.USB3.0 rate has very big promotion, but CPU is needed to handle the disadvantage close with transmission range
Still it does not solve.
1394 interfacings are relative complex, and the popularity rate of interface is not high, slowly by market.
Gigabit Ethernet requires the transmitting terminal of image, receiving end to require the high speed envelope that CPU participates in carrying out ICP/IP protocol
Packet/solution package processing, needs to connect corresponding PHY device, transformer chip, RJ45 interface, volume is relatively large.
LVDS bus interface cannot support the transmission of high-speed data, and effective transmission range is shorter.
Camera Link interface volume is larger while expensive, and transmission range is short.
Therefore technical problem urgently to be solved is how simple using one kind, low cost device by high-speed video now
Image is handled from being transferred on the receiving device of rear end in remote high-speed camera.
Summary of the invention
In order to solve the problems in background technique, the present invention relates to a kind of high-speed video collecting and transmitting methods, will be non-standard
High-speed video images realize the lossless high-speed transfer of long range by way of format conversion.
Concrete principle of the invention is:
The high-speed video collecting and transmitting method transmitted at a distance can be supported the present invention is intended to provide a kind of, using will be nonstandard
The video of quasiconfiguaration is mapped to the method transmitted again after the video format of standard, by 640*480@K1The high-speed video of fps
It is mapped to the 1920*1080p@K for meeting BT.1120 standard2In fps HD video format, then by the data of HD video format
Demapping is carried out, 640*480@K is recovered1Coding output is carried out after fps high-speed video data again.
The specific technical solution of the present invention is:
The present invention provides a kind of high-speed video collecting and transmitting methods, which comprises the following steps:
1) high speed image of noncanonical format is acquired；
The high speed image of the noncanonical format is 640*480@K1Fps, high speed image format are YCbCr；Wherein, K1=
200 or 400；
2) high speed image of noncanonical format is mapped to the HD video data of reference format by the mapping ruler of setting；

3) the HD video data of reference format are reverted to the high speed figure of noncanonical format by the demapping rule of setting
As data；
4) high speed image data of the noncanonical format recovered is subjected to HEVC/H265 compressed encoding；
5) compressed bit stream of the high speed image of noncanonical format is exported.
Above-mentioned steps 2) in set mapping ruler be specifically:
A1, K is defined2Frame meets the transformat of the high clear video image of BT.1120 standard, the high definition view of each frame standard
Effective image section is set in the transformat of frequency image, the effective image section, should for filling high speed image data
Total 1920 column in effective image section and 1080 rows, i.e. 2073600 bytes；
B1, first character section is inserted into serial number byte 0 in the effective image section of the 1st clear video format of vertical frame dimension, then connects
Continuous insertion 1-6 frame high speed image, and number is 1~6 respectively, is finally embedded in the preceding 360 row image of the 7th frame high speed image,
And numbering is 7；
C1, first character section is inserted into serial number byte 1 in the effective image section of the 2nd clear video format of vertical frame dimension, then embedding
Enter rear 120 row of the 7th frame high speed image, then be consecutively embedded 8-13 frame high speed image, number is 8~13, is finally embedded in the 14th
Preceding 240 row of frame high speed image, and numbering is 14；
D1, first character section is inserted into serial number byte 2 in the effective image section of the 3rd clear video format of vertical frame dimension, then embedding
Enter rear 240 row of the 14th frame high speed image, then be consecutively embedded 15-20 frame high speed image, number is that the 15~20, the 3rd vertical frame dimension is clear
Extra byte after the 20th frame 640*480 format-pattern of effective image section receiving of video format is uniformly filled with 00；So far,
In the high speed image effective image section that continuous 20 vertical frame dimension speed loading images are just entered to the continuous clear video format of 3 vertical frame dimension；
E1, step B1~D1 is repeated, until by remaining 21~K1Vertical frame dimension speed loading images are to 4~K2Column high definition view
In the effective image section of frequency format.
Above-mentioned steps 3) in set demapping rule be specifically:
A2, data in the effective image section of the 1st clear video format of vertical frame dimension are obtained, judges first character section, if the
One byte thens follow the steps B2 for 0, if first character section thens follow the steps C2 for 1, if first character section thens follow the steps for 2
D2；
B2, it is continuously withdrawn 1-6 frame high speed image in the effective image section of the 1st clear video format of vertical frame dimension and is directly pressed
Code is reduced the staff, number is respectively 1~6, is then cached 360 row images before the 7th frame high speed image, then return step
A2；
C2, rear 120 row for first taking out the 7th frame high speed image in the effective image section of the 2nd clear video format of vertical frame dimension, by it
Compressed encoding is carried out after being spliced with 360 row images before the 7th frame high speed image that caches in step B2, is then continuously taken again
8-13 frame high speed image carries out compressed encoding out, and frame number is 8~13, and finally before the 14th frame high speed image 240 advance
Row caching, finally returns to step A2；
D2, rear 240 row for first taking out the 14th frame high speed image in the effective image section of the 3rd clear video format of vertical frame dimension, with
The preceding 240 row image of the 14th frame high speed image cached in step C2 carries out compressed encoding after being spliced, and is then continuously withdrawn
15th~20 frame high speed image carries out compressed encoding preparation, and frame number 15~20 remaining byte will be abandoned below, and be finally returned to
Step A2；
E2, step A2~D2 is repeated, until by K2Data in the effective image section of the clear video format of vertical frame dimension all connect
It harvests complete.
The beneficial effects of the present invention are:
The high-speed video transmission method used in the present invention in the whole process passes through the high speed image of noncanonical format
