Description

Technical Field

[0001] The present invention relates to the field of satellite communication technology, and in particular to a method, device, electronic device and computer-readable storage medium for real-time generation and transmission of target information. Background Art

[0002] Beidou short message communication is a unique function of the Beidou satellite navigation system and an important component of it. It has been widely used in various fields. Beidou short messages can distribute shorter text information through Beidou satellites, without being restricted by time and space, and have the characteristics of all-weather and not affected by natural disasters. With Beidou short message communication, emergency communications can be carried out through short messages in disaster weather such as typhoons and earthquakes, or when ordinary mobile communication signals cannot cover, and other Beidou satellites can be used for emergency data transmission that requires normal communication.

[0003] In the modern battlefield environment, the rapid acquisition and transmission of information has an increasingly greater impact on combat outcomes. Using satellites to acquire ground images, extract image information, form text information and distribute it can greatly shorten the time for information acquisition and transmission, keep abreast of battlefield conditions, and help win the battlefield.

[0004] At present, many technical solutions for on-board image data processing and distribution have been proposed at home and abroad. In summary, the main solution is to first complete the relevant processing of the image through the on-board image processing algorithm, and then transmit the image to the data processing center or terminal on the ground, and then analyze and make decisions on the image on the ground. It can be seen that although the existing technology can complete the real-time automatic processing of images on the satellite, it ignores the automatic interpretation of the target in the image, making the information transmission of the existing technology less timely; at the same time, because the object of data distribution is image, the amount of data contained is large, which makes the data distribution slow and costly, and data corruption is prone to occur during the transmission process.

[0070] The purpose of the embodiments of the present invention is to provide a method, device, electronic device and computer-readable storage medium for real-time generation and transmission of target information to solve the problem of slow distribution speed of existing satellite image target information.

[0071] Please also read Figure 1-2 , a method for real-time generation and transmission of target information, comprising:

[0072] S1: Receive target acquisition request;

[0073] In actual applications, users can send target acquisition requests to satellites through Beidou terminals (or other user terminal devices) via Beidou satellites (or other methods).

[0074] S2: Collect image information according to the target acquisition request;

[0075] S2 specifically includes:

[0076] S2.1: Determine whether the target acquisition request contains time and longitude and latitude requirements;

[0077] S2.2: If the target acquisition request includes time and longitude and latitude requirements, image information is collected according to the corresponding time and longitude and latitude;

[0078] S2.3: If the target acquisition request does not include time and longitude and latitude requirements, the image information is collected according to the default settings.

[0079] See also Figure 3 , the present invention starts to interpret after receiving the target acquisition request, passes the interpreted required target name to the target identification and positioning module, and collects images according to the time and longitude and latitude requirements in the request. If the time and longitude and latitude information are not specified, the image is collected according to the default settings. After the image acquisition module (satellite image sensor) completes the image acquisition, the image is first sent to the image preprocessing module to complete image preprocessing and other related operations. The image preprocessing module first extracts and saves information such as image acquisition time, longitude and latitude range, etc., to facilitate subsequent operations to extract at any time. Afterwards, the image preprocessing module uses the built-in algorithms and programs to complete image geometric correction, orthorectification, image enhancement, atmospheric correction and other preprocessing operations to improve the accuracy of target identification and positioning, and finally sends the preprocessed image to the target identification and positioning module to locate the target.

[0080] The present invention can eliminate geometric and radiation distortions caused by factors such as atmospheric transmission, the sensor itself, and the curvature of the earth by preprocessing image information, thereby enhancing image clarity and contrast and improving target recognition accuracy.

[0081] S3: Using target recognition and positioning algorithms to identify and locate targets in the image information to obtain the position and number of the required targets in the image;

[0082] Furthermore, S3 specifically includes:

[0083] S3.1: Use target recognition and positioning algorithms to identify and locate targets in image information to obtain recognition results;

[0084] It should be noted that the target recognition and positioning algorithm of the present invention first completes the construction of a target data reference library on the ground, completes the relevant training of the target recognition and positioning algorithm according to the characteristics of the target in the data reference library, and builds it into the target recognition and positioning module for identifying and positioning the target in the image information.

[0085] S3.2: If the recognition result includes the desired target, the number of the desired targets and the position of the center pixel of the desired target are recorded;

[0086] S3.3: If the required target is not identified, determine whether the time requirement is met when collecting images next time. If the time requirement is not met, send the instruction of no target information to the text information conversion module; if the time requirement is met, return to S2.

[0087] For further information, see Figure 4 If the recognition result contains multiple required targets, they are recorded in sequence, and finally the recorded information is sent to the text information conversion module; if the required target is not recognized, first determine whether the time requirement is met when collecting images next time, if the time requirement is not met, send the instruction of no target information to the text information conversion module; if the time requirement is met, repeat S2-3. If the required target information is still not obtained after repeating three times, send the instruction of no target information to the text information conversion module. It should be noted that the text information conversion module of the present invention is used to convert the required target information into text information.

[0088] S4: Determine the longitude and latitude coordinates of the desired target according to the longitude and latitude range of the image and the position of the desired target in the image;

[0089] S5: converting the acquisition time of the image information, the latitude and longitude coordinates and the number of the required targets into text information;

[0090] Furthermore, S5 includes:

[0091] S5.1: Convert the acquisition time of the image into time data in the format of month|day|hour|minute|second|;

[0092] S5.2: Convert the longitude and latitude coordinates of the desired target into position data in the format of target longitude | target latitude | target name;

[0093] S5.3: converting the quantity information into quantity data in the format of target name|target quantity;

[0094] S5.4: The time data, the location data and the quantity data are integrated to form text information; wherein the format of the text information is:

[0095] Time|Number of targets|Name of targets|Longitude of targets|Latitude of targets.

[0096] See also Figure 5 In practical applications, S4-5 of the present invention is accomplished by using a text information conversion module. The text information conversion module consists of four parts:

[0097] a. Time interpretation module: extract the sensor image acquisition time recorded by the image preprocessing module, and convert it into time data in the format of month | day | hour | minute | second according to the recorded time.

[0098] b. Target interpretation module: According to the target information obtained by the target recognition and positioning module, the targets are counted and sorted. In order to save bytes occupied by text, only the total number and the position of each target of the same type are recorded.

[0099] c. Position interpretation module: Based on the latitude and longitude range of the image and the coordinates of the target in the image, the latitude and longitude coordinates of the target are generated through comprehensive calculation;

[0100] d. Text generation module: Integrate the information of the above three parts to form text information. The text format is:

[0101] time|number of targets 1|name of targets 1|position 1|position 2|…|number of targets 2|name of targets 2|position 1|position 2|….

[0102] If the identification and positioning module outputs the "no target information" instruction, it will output "no relevant target information obtained".

[0103] S6: Convert the text information into Beidou short message format and distribute it to each Beidou terminal.

[0104] In actual applications, when the ground communication base station is destroyed or the ordinary mobile communication signal cannot cover, information transmission is often forced to terminate, which leads to a decrease in the degree of mastery of the target and affects the normal execution of decisions. The present invention realizes the generation of image data and the distribution of information through Beidou short messages, ensures the stability of data transmission, and is conducive to the normal progress of operations.

[0105] Furthermore, S6 specifically includes:

[0106] S6.1: Determine whether the size of the text information exceeds a limit threshold;

[0107] S6.2: If the size of the text message exceeds the limit threshold, the text message is distributed to each Beidou terminal in batches in Beidou short message format;

[0108] S6.3: If the size of the text message does not exceed the limit threshold, the text message is directly distributed to each Beidou terminal in the Beidou short message format.

[0109] In practical applications, the intelligence distribution module can be used to convert text information into Beidou short message format information, send it to Beidou satellites, and then distribute it to various Beidou terminals via Beidou satellites to complete the real-time generation and distribution of image data. Since the number of characters in Beidou short messages is limited, each time it is sent, it should be identified whether the content size exceeds its limit. If it exceeds, it will be sent in batches.

[0110] The target recognition and positioning module and the image translation module in the present invention are arranged inside the remote sensing satellite. The user can directly (or through Beidou and other communication satellites) send a target information acquisition instruction to the device. After receiving the instruction, the device sends an instruction to the satellite image sensor to collect the image, and then transmits the image back to the device to start the target information extraction and distribution operations. The image first passes through the image preprocessing module of the device to complete the preprocessing operations such as geometric correction, image enhancement, and atmospheric correction of the image, and obtains the relevant parameter information such as geography and time recorded in the image file, and transmits it to the text information conversion module; then, the preprocessed image is transmitted to the target recognition and positioning module, and the target recognition and positioning algorithm preset in the module is used to identify and locate the required target in the image, and the relevant information of the required target is obtained; then, the target information is input into the text information conversion module, and the information such as the latitude and longitude, time, etc. of the image that has been transmitted is sorted and summarized to form text information; finally, the text information is transmitted to the intelligence distribution module, and the data distribution is completed through the short message function of the Beidou satellite.

[0111] Conventional satellite image target information generation and distribution requires that the satellite image be transmitted to the ground, which will process the response and then distribute the text information through ground base stations or communication satellites. This overall process is relatively complicated. The present invention can use the target recognition and positioning module and the text information conversion module to automatically extract the main information in the image, and the intelligence distribution module uses the short message function of the Beidou satellite to achieve data distribution. Therefore, the present invention can directly complete the generation, processing, judgment and distribution of image data on the satellite, without the need to transmit the image to the ground for processing and distribution, saving the time of image data processing on the ground, improving the timeliness of data transmission, and facilitating the rapid and accurate implementation of combat operations. At the same time, since the distribution object is eventually changed into a shorter text message, the cost of data distribution is greatly reduced and the quality of information is improved.
