Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the disclosure, as detailed in the appended claims.
An embodiment of the present disclosure provides a data transmission method, as shown in fig. 1, the data transmission method includes the following steps:
101. acquiring the acquisition parameters and the target transmission bandwidth of each acquisition module.
The acquisition information comprises acquired position information, acquisition distance, acquisition time, acquisition focal length and acquisition range.
For example, the a acquisition module is deployed in the square plane of the vehicle at coordinate (x.y), acquires a distance of 10m from the target object, acquires a focal length of 4mm, and acquires data ranging from 45 ° to 125 °.
According to the method, the acquisition end acquires the original data and the acquisition parameters of the original data through the unmanned vehicle.
The target image refers to N images captured by the unmanned vehicle.
The unmanned vehicle has at least one acquisition module deployed on at least one plane.
For example, 4 cameras are deployed right in front of the vehicle, 2 cameras are deployed in the left and right branches of the vehicle, and 3 cameras are deployed in the rear of the vehicle.
In particular embodiments, capturing the image of the unmanned vehicle may be capturing the image upon request, or capturing the image by a preset rule.
In an optional embodiment, the unmanned vehicle can acquire the acquisition parameters of the image after acquiring the image, and sends the image to the acquisition terminal after marking the acquired image through the acquisition parameters.
In an alternative embodiment, the acquisition end may be a hardware device or a software module.
In an alternative embodiment, the acquisition end may be deployed in a control platform for controlling the unmanned vehicle.
102. And determining a first area and a second area according to the acquisition parameters and the target transmission bandwidth.
Wherein the first region is at least a region including a plurality of acquisition modules or a partial region of an image acquired in one acquisition module.
Wherein the second region is at least a region comprising a plurality of acquisition modules or a partial region of an image acquired in one acquisition module.
In the method provided by the present disclosure, because bandwidth resources are insufficient in the transmission process, the acquisition region in the vehicle needs to be divided into an important region, i.e., a first region, and a non-important region, i.e., a second region.
For example, the first region may be a region of the vehicle that is facing the target object, and the second region may be a region lateral to the vehicle.
For example, the first region may be an image region at a central position in the image captured in the first capture module of the vehicle, and the second region may be an image region at an edge position in the image captured in the first capture module of the vehicle.
Correspondingly, if the target transmission bandwidth is larger than the resources required by data transmission, all the acquisition modules can be divided into the first acquisition module, that is, all the images are subjected to high-definition coding processing.
The image display quality of the first area is higher than that of the second area, for example, the first area is a high definition display area, and the second area is a normal display area.
Different scenarios are presented here to illustrate how the first and second regions are divided:
the first example is as follows: the first area is a certain area in the image acquired by the acquisition module:
in the method provided by the present disclosure, determining the first area according to the acquisition parameter and the transmission resource specifically includes:
acquiring an image acquired by the acquisition module, and dividing the image into N areas;
acquiring acquisition parameters of the N areas, wherein the acquisition parameters at least comprise acquisition positions and acquisition resolutions;
and determining a first region and a second region in the N regions according to the acquisition parameters.
The area division can meet the image transmission requirement of each module under the better network condition, and in order to improve the image transmission efficiency, the image acquired by each acquisition module is optimized, the area needing high-definition coding transmission is divided into a first area, and other areas are divided into a second area.
Example two: the first region is a region containing the acquisition modules:
in the method provided by the present disclosure, determining, according to the acquisition parameter and the transmission resource, a first acquisition module in a first area specifically includes:
acquiring acquisition parameters corresponding to each acquisition module in the first plane;
determining target acquisition parameters according to the target transmission bandwidth, wherein the target acquisition parameters at least comprise a first angle and a first distance which are matched with the acquisition angle;
and when the acquisition parameters corresponding to the acquisition module are matched with the target acquisition parameters, determining the acquisition module as a first acquisition module.
The area division is that under the condition that the network is not good, the image transmission requirement of each module cannot be met, so in order to improve the efficiency of image transmission, each acquisition module is optimized, the acquisition modules needing high-definition coding transmission are divided into a first area, and other area acquisition modules are second areas.
The selection of the first area depends on the focal length and the irradiation distance of the camera, and the unmanned combat tank is unmanned detection, so that the camera is selected to have a long irradiation distance and a large focal length value. The larger the focal length is, the farther the visual distance is, the smaller the angle of view is, and the sharper the picture is.
For example, when the bandwidth resource is matched with the preset bandwidth, the first area is determined to be in a high-definition display mode within a camera shooting distance of 50 meters and a plane angle vertical to 90 degrees, and the second area is in a non-high-definition display mode within a range of 45 degrees on two sides.
And if the bandwidth resources are not matched with the preset bandwidth resources, adjusting acquisition parameters, and if the first area is determined to be the camera shooting distance of 30 meters, displaying in a high-definition mode within a plane angle vertical to 90 degrees.
The determining of the target acquisition parameters according to the target transmission bandwidth in the above steps is used to determine different first regions according to different bandwidth resources, so that the key image can be transmitted more efficiently, and specifically may include:
acquiring a target transmission resource and a preset transmission resource, wherein the preset transmission resource is used for indicating a resource required by transmitting original data;
when the target transmission resource is not matched with the preset transmission resource, determining a threshold interval in which the target transmission resource is located:
target acquisition parameters are determined from the threshold interval and a target map indicating a relationship between at least one threshold region and at least one set of acquisition parameters.
For example, when the bandwidth is smaller than a first preset threshold, determining that the acquisition module capable of shooting the target object in the front side is a first module;
when the bandwidth is smaller than a second preset threshold, determining that the acquisition module which can shoot the target object in the front and has the acquisition distance of 20 meters from the target object is a first module.
103. First data acquired by the first area and second data acquired by the second area are acquired.
The display quality of the first data is higher than the display quality of the second data.
Specifically, the first acquisition module may include a plurality of acquisition modules, and the first data is acquired and marked by the plurality of acquisition modules.
Specifically, the second acquisition module may include a plurality of acquisition modules, and the second data is acquired and marked by the plurality of acquisition modules.
104. And coding and processing the first data according to the first coding rule to generate a first code stream, and coding and processing the second data according to the second coding rule to generate a second code stream.
The coding quality of the first coding rule is higher than the coding quality of the second coding rule.
The method also generates a target code stream according to the first code stream and the second code stream, and sends the target code stream to the receiving end.
And after the receiving end acquires the target code stream, the first code stream and the second code stream are decoded and displayed respectively.
Specifically, whether the code stream is the code stream of the first area or the code stream of the second area is marked in the target code stream;
furthermore, the code stream is marked to be acquired by the acquisition module at which position of the vehicle, so that the decoding end can conveniently splice and process a plurality of code stream data.
Specific examples are set forth herein to illustrate how to encode processing first data according to a first encoding rule and to encode processing second data according to a second encoding rule:
the first condition is as follows: when the network state is good, namely the current bandwidth is matched with the preset bandwidth, each area in the unmanned vehicle is a first area, and the second area is empty, so that the images collected by each module of the unmanned vehicle are coded, and further the collected images can be subjected to high-definition coding.
And a second condition: if the current bandwidth is smaller than a first preset threshold value or the packet loss rate is larger than a second threshold value, displaying the acquired images of the cameras in a regional mode, specifically, determining a key region in the middle of the unmanned vehicle as a first region, and carrying out high-definition coding on data in the first region; if the non-key area at the edge is determined to be a second area, carrying out non-high-definition coding on the data of the second area;
and a third situation: when the bandwidth is smaller than a third threshold or the packet loss rate is larger than a fourth threshold, wherein the third threshold is smaller than the first threshold and the fourth threshold is larger than the second threshold, which indicates that the network state is further deteriorated, determining that all cameras in the front row area of the vehicle are the first area, and transmitting the images acquired by the first area; for example, if there are three cameras in front of the vehicle, only the images collected by the three cameras are transmitted.
And if the network state is further deteriorated, determining that the camera arranged at the central position in the front row area of the vehicle is the first area, and transmitting the image acquired by the first area.
The deployment of the above method in practice can be as in fig. 1 a: the unmanned vehicle is provided with 4 cameras, the first camera, the second camera and the third camera are determined to be acquisition modules in a first area and the fourth camera is determined to be an acquisition module in a second area through bandwidth and acquisition parameters, the acquisition end acquires first data by acquiring data acquired in the first area and second data by acquiring data acquired in the second area, the first data are processed through a high-definition coding algorithm, the second data are processed through a common coding algorithm, and the first data and the second data are transmitted to the receiving end in different areas.
In an alternative embodiment, the present disclosure may be applied to an application of controlling an unmanned vehicle to survey a target object, specifically including the following steps:
step one, the unmanned vehicle acquires data acquired by each acquisition module and sends the data to the control platform.
For example, when an unmanned fighting vehicle with an acquisition device goes out to survey the terrain, dynamic images are acquired in real time through a plurality of cameras, and the images acquired by the cameras are converged on corresponding control platforms on the fighting vehicle.
Secondly, the collecting end collects the converged images and sends the converged images to a command department control center;
and S, the equipment acquires the image displayed on the control platform and sends the image back to the command department in a wireless mode.
In an optional embodiment, since the transmission of the plurality of images consumes bandwidth, the images may be subjected to partition encoding processing and transmitted in a poor network state (such as low bandwidth or large packet loss), specifically divided into a key region and an edge region, and the key region is subjected to high-definition encoding.
And step three, the control center decodes and displays the image after receiving the collected image.
The command department control center arranges the receiving end, so that the field environment acquired by the unmanned vehicle in real time can be checked in time, and the camera can be operated to control the direction and distance change of the camera.
According to the data transmission method provided by the embodiment of the disclosure, after the acquisition end acquires the data acquired by the unmanned vehicle, the data is divided into the data of the key area and the data of the non-key area, and the data is sent to the receiving end in different areas.
The invention provides an image transmission method applied to an unmanned vehicle, which can return images acquired by the unmanned vehicle to a control center in real time, and simultaneously provides a strategy of regional coding of the images in order to reduce code stream and improve image transmission efficiency.
