Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present invention.
Example 1:
fig. 1 is a schematic diagram of a data transmission process provided in an embodiment of the present invention, where the process includes the following steps:
s101: and acquiring digital information of data corresponding to each frame of image.
The data transmission method provided by the embodiment of the invention is applied to image acquisition equipment.
In the embodiment of the invention, for each frame of acquired image, the image acquisition equipment transmits the data corresponding to the frame of image to the server. The image acquisition device may acquire data corresponding to the frame of image first, and acquire digital information of the data corresponding to the frame of image when data transmission is performed, and specifically, how to acquire corresponding digital information according to the data corresponding to the frame of image is prior art and is not described herein again.
S102: the digital information is converted to analog information.
Since the transmission efficiency is low due to the long transmission time of the digital information during data transmission, the digital information is converted into the analog information in the embodiment of the present invention, and the efficiency of data transmission is improved by transmitting the analog information. How to convert digital information into analog information is the prior art, and is not described herein again.
S103: and transmitting the analog information by adopting an invalid signal line corresponding to the frame image.
In order to increase the data transmission amount, in the embodiment of the present invention, the converted analog information is transmitted by using the invalid signal line corresponding to the frame image, so that the transmitted data amount is increased.
In the embodiment of the invention, for each frame of image, the digital information of the data corresponding to the frame of image is converted into the analog information, and the analog information after conversion is transmitted by adopting the invalid signal line in the frame of image. Since data transmission is performed using an invalid signal line in an image when data is transmitted, more data can be transmitted.
Example 2:
in order to improve the efficiency of data transmission, on the basis of the above embodiments, in an embodiment of the present invention, the converting the digital information into analog information includes:
for each byte of digital information, the byte is converted to analog information.
In the embodiment of the invention, the transmission time of the digital information is longer, in order to improve the efficiency of data transmission, each byte in the digital information is converted into analog information, and the converted analog information is transmitted when the data transmission is carried out.
Specifically, for a certain data Date to be transmitted, where B is a byte in the digital information, the determination formula of the analog information corresponding to each bit in the digital information is as follows:
wherein Bi is each bit contained in one byte, and i takes a value of 0-7. That is, if a value of a certain bit in the digital information is 1, the analog information corresponding to the bit is 255, and if a value of a certain bit in the digital information is 0, the analog information corresponding to the bit is 0.
In order to implement data transmission, on the basis of the foregoing embodiments, in an embodiment of the present invention, the transmitting the analog information by using the invalid signal line corresponding to the frame image includes:
aiming at each byte in the digital information, acquiring a pixel point corresponding to each bit in the byte in an invalid signal line;
aiming at each bit in the byte, setting the gray value of the pixel point corresponding to the bit as a numerical value corresponding to the bit converted into analog information in the digital information;
and transmitting the invalid signal line data after the gray value of the pixel point is set.
In the prior art, an invalid signal line includes a plurality of pixel points, each pixel point has a corresponding gray value, and the gray value corresponding to the pixel point is used for recording related information of an image. In the embodiment of the invention, the gray value of each pixel point in the invalid signal line is set as the numerical value after each bit in the digital information is correspondingly converted into the analog information, so that the invalid signal line transmits the analog information, and the transmitted data volume is increased.
Each byte of the digital information includes a predetermined number of bits, the predetermined number is usually 8, that is, each byte of the digital information includes 8 bits. Specifically, the process of setting the gray value of the pixel point is as follows: when analog information is transmitted, a pixel point representing each bit in each byte in an invalid signal line corresponding to each byte in digital information can be obtained first, and after the pixel point corresponding to each bit in the byte is obtained, the gray value of the pixel point corresponding to each bit is set as a numerical value obtained after the bit is converted into the analog information. In order to improve the accuracy of data transmission, on the basis of the foregoing embodiments, in an embodiment of the present invention, for each bit in the byte, after setting the gray value of the pixel point corresponding to the bit as the corresponding numerical value after the bit is converted into the analog information in the data information, and before transmitting the invalid signal line after the gray value is set, the method further includes:
acquiring a first pixel point and a second pixel point which are adjacent to a pixel point corresponding to the first bit in the byte and are not provided with a gray value in the invalid signal line;
setting the gray value of the first pixel point as a preset high-order numerical value; and setting the gray value of the second pixel point as a preset low-order numerical value.
Because analog information is easy to have a larger error rate in the transmission process, if the error rate is larger, the accuracy of data transmission is lower, so in the embodiment of the invention, the generation of the larger error rate in the transmission process of the analog information is avoided by setting the preset high-order numerical value and the preset low-order numerical value, and specifically, a preset high-order numerical value and a preset low-order numerical value are set for each byte in the analog information.
And when setting up the predetermined high order figure value and predetermine the low order figure value of every byte, can acquire the pixel that sets up to the predetermined high order figure value of this byte and predetermine the low order figure value that corresponds earlier, and is concrete, and the acquisition process that sets up to the pixel of predetermineeing the high order figure value and set up to the pixel of predetermineeing the low order figure value is: and acquiring a pixel point corresponding to the first bit in the byte in the invalid signal row, and acquiring a first pixel point and a second pixel point which are adjacent to the pixel point corresponding to the first bit and are not provided with gray values. That is to say, for each byte, the pixel points corresponding to the byte in the invalid signal line may be, from left to right: the byte is corresponding to a first pixel point with a preset high numerical value, the byte is corresponding to a second pixel point with a preset low numerical value, and each bit in the byte is converted into analog information and then is corresponding to the pixel point. Of course, for each byte, the arrangement mode of the pixel points corresponding to the byte in the invalid signal line from left to right may be other modes.
Aiming at each byte in the analog information, after a first pixel point and a second pixel point corresponding to the byte are determined, the gray value of the first pixel point is set as a preset high-order numerical value, and the gray value of the second pixel point is set as a preset low-order numerical value, so that the byte is transmitted through an invalid signal line and is converted into a numerical value after the analog information, the preset high-order numerical value corresponding to the byte and the preset low-order numerical value corresponding to the byte.
Fig. 2 is a schematic diagram for setting the gray-level value of the pixel point corresponding to each byte according to the embodiment of the present invention.
Fig. 2 illustrates an example in which the gray values of two pixel points before the pixel point corresponding to each byte are respectively set as the preset high-order value and the preset low-order value, as can be seen from fig. 2, the gray values of adjacent pixel points may be sequentially set as the preset low-order value 0, the preset high-order value 255, and then the value of each bit in the byte converted into analog information is set. Therefore, the transmitted gray value of the pixel point which is set to be the preset low-order numerical value and the preset high-order numerical value corresponding to the byte is used for correcting the numerical value of each byte after being converted into the analog information, and the numerical value of each byte after being converted into the analog information is prevented from generating deviation in the transmission process.
Example 3:
fig. 3 is a schematic diagram of a data transmission process provided in an embodiment of the present invention, where the process includes the following steps:
s301: and receiving each invalid signal line data sent by the image acquisition equipment.
The data transmission method provided by the embodiment of the invention is applied to the server.
In the embodiment of the invention, data transmission is carried out through each invalid signal line data sent by an image acquisition device, and a server receives each invalid signal line data sent by the image acquisition device, wherein the signal line data received by the server and sent by the image acquisition device are marked to indicate whether the corresponding signal line is an invalid signal line or an effective signal line.
S302: aiming at each invalid signal line data, acquiring analog information transmitted by the invalid signal line data; converting the analog information into digital information; and acquiring the data of the frame of image corresponding to the digital information.
After receiving each invalid signal line data sent by the image acquisition device, acquiring data included in the invalid signal line data for each invalid signal line data, specifically, acquiring data included in the invalid signal line data by the following steps: and acquiring analog information transmitted by the invalid signal line, converting the acquired analog information into digital information after acquiring the analog information, and acquiring data corresponding to the digital information in the invalid signal line data through the digital information. Specifically, how to obtain data in the invalid signal line data corresponding to the digital information through the digital information is the prior art, and details are not described herein.
Example 4:
in order to accurately determine digital information corresponding to analog information, on the basis of the foregoing embodiments, in an embodiment of the present invention, the acquiring analog information transmitted by the invalid signal line data includes:
sequentially identifying the gray value of each pixel point in the invalid signal row, and acquiring a first pixel point with the gray value set as a preset high-order numerical value and a second pixel point with the gray value set as a preset low-order numerical value;
acquiring each pixel point between adjacent first pixel points and second pixel points; and acquiring analog information corresponding to the gray value of each pixel point.
In the embodiment of the invention, each bit of each byte in the digital information is easy to generate errors when being transmitted after being converted into the analog information, so that the server can firstly sequentially identify the gray value of each pixel point in the invalid signal line, obtain a first pixel point which is adjacent to the invalid signal line and is set as a preset high-order numerical value and a second pixel point which is adjacent to the invalid signal line and is set as a preset low-order numerical value according to each pixel point, obtain a preset number of pixel points behind the adjacent first pixel point and the adjacent second pixel point after obtaining the first pixel point and the second pixel point, and determine the analog information corresponding to each pixel point according to the obtained gray value of each pixel point.
Specifically, in the embodiment of the present invention, the process of determining the pixel point corresponding to each byte in the simulation information is as follows: and sequentially determining a preset number of adjacent pixels with gray values, wherein the gray values of the preset number of pixels sequentially correspond to a preset high-order numerical value corresponding to a certain byte in the digital information, the corresponding preset low-order numerical value digital information and a numerical value obtained by converting each bit in the byte in the digital information into analog information. And because each byte contains 8 units, the pixel points with the preset number are 10 pixel points generally, wherein the 10 pixel points contain the pixel points corresponding to the 8 units in the byte, the gray value corresponding to the byte is set as a preset high-order numerical value, and the gray value corresponding to the byte is set as a pixel point corresponding to a preset low-order numerical value.
For example, M/T bytes of analog information may be stored and transmitted for each invalid signal line in an M × N image, where M refers to the number of pixels in each line in the M × N image, N refers to the number of lines in the M × N image, and the minimum value of T is 10, that is, at most M/10 bytes of digital information after being converted into analog information may be stored and transmitted for each invalid signal line. Wherein M × N may be 1280 × 720, 1920 × 1080, 2592 × 1944, 3840 × 2160, or the like.
For each byte in the analog information, if the gray value corresponding to the byte in the analog information is set, the adjacent pixels are sequentially the pixel corresponding to the byte from left to right, wherein the pixel is used for setting the gray value to be a preset high-order numerical value, the pixel corresponding to the byte is used for setting the gray value to be a preset low-order numerical value, and the pixel is used for setting the gray value to be a numerical value after each bit in the byte is converted into the analog information, then when a first pixel and a second pixel are determined, a preset number of pixels can be sequentially obtained, wherein the two pixels of the preset number of pixels are the first pixel and the second pixel respectively.
In order to accurately determine digital information corresponding to analog information, in the embodiments of the present invention, on the basis of the foregoing embodiments, the converting the analog information into the digital information includes:
and converting the gray value of each pixel point into digital information according to the obtained gray value of each pixel point.
In the embodiment of the present invention, for each byte in the digital information, after the pixel point corresponding to the analog information converted from each bit in the byte is obtained, the gray value of the pixel point corresponding to each bit in the byte is obtained, and the analog information corresponding to the gray value of the obtained pixel point is converted into the digital information.
Because the transmitted analog information has loss in the data transmission process, the value of the analog information transmitted by the invalid signal line acquired by the server is not fixed, such a conversion of analog information transmitted in an image into digital information by a server may have a problem of a conversion error, and the number of pixel points on the invalid signal line is large, it cannot be predicted which pixel points have large gray value distortion degree, therefore, in the embodiment of the present invention, for each bit in the byte, and converting the analog information of the gray value of the pixel point corresponding to the bit into digital information according to the gray value of the first pixel point corresponding to the byte and set as a preset high-order numerical value, the gray value of the second pixel point corresponding to the byte and set as a preset low-order numerical value, and the gray value of the pixel point set as a numerical value after the bit is converted into the analog information. Specifically, the digital information T determined by the server is:
the method comprises the steps that ImageDate is a gray value of a certain pixel point after transmission, L is a gray value obtained after transmission of the pixel point with the gray value set as a preset low-order numerical value, and H is a gray value obtained after transmission of the pixel point with the gray value set as a preset high-order numerical value; Δ 0 and Δ 1 are preset values; while H- Δ 1> L + Δ 0.
That is, the server knows that the gray values of the pixel points at the preset positions in the adjacent preset number of pixel points sequentially set with the gray values represent the preset low-order numerical value and the preset high-order numerical value respectively, wherein the preset low-order numerical value can be a value obtained by converting low-order 0 in the digital information into the analog information, and the preset high-order numerical value can be a value obtained by converting high-order 1 in the digital information into the analog information. The gray values of the 2 pixel points which are acquired at the same time after transmission are L and H, the received gray values of the pixel points at other positions can be compared with H-delta 1 and L + delta 0, and when the gray value of one pixel point is greater than or equal to H-delta 1, the digital information corresponding to the bit represented by the pixel point is considered to be high-order 1; and when the gray value of one pixel point is less than or equal to L + delta 0, the digital information corresponding to the bit represented by the pixel point is considered as low-order 0.
Fig. 4 is a schematic diagram of a transmission process of a pixel point corresponding to analog information after conversion of one byte in digital information according to an embodiment of the present invention.
Fig. 4 illustrates an example in which the gray values of two pixel points before the pixel point corresponding to each byte are respectively set as the preset high-order value and the preset low-order value, as can be seen from fig. 4, after data transmission, the gray values of the pixel points may change, so that the digital information after conversion of the analog information corresponding to each bit in the byte is accurately determined by setting the gray values as the gray values of the transmitted pixel points of the preset low-order value and the preset high-order value, and the problem that the converted digital information is wrong due to deviation of the analog information in the transmission process is avoided.
