Abstract
Description
Technical Field
[0001] This invention relates to the field of automatic target identification technology, and specifically to a target identification method and system suitable for military management. Background Technology
[0002] Military target identification technology refers to the accurate identification and judgment of targets on land, sea, or in the air through specific technical means, providing reliable basis for command and decision-making and accurate guidance and support for military operations. For example, in war exercises, the military can identify enemy targets to determine the enemy's troop strength, equipment, and other information; in counter-terrorism operations, the police can identify suspected targets to track and combat terrorists; and in maritime patrols, the coast guard can identify suspicious vessels to combat piracy and illegal fishing boats.
[0003] In military target identification, target information can be acquired through various channels, such as acquiring images containing military target information via vehicle-mounted, airborne, satellite, and UAV platforms. When targets are concealed in complex terrain and topographical environments, a large number of images need to be acquired for comparison and calculation. This results in a large computational load and low accuracy in processing and analyzing such image data. In military operations, decision-making needs to be rapid and accurate. Therefore, a method for intelligent target identification and judgment is needed that can not only perform rapid and automatic analysis of massive amounts of data but also ensure data accuracy, thus providing important evidence for military patents.

This solution can not only automatically analyze the data to quickly complete the target identification, but also effectively ensure the accuracy of the identification.
[0005] To achieve the above objectives, the present invention proposes the following technical solution:

[0028] Real-time remote sensing images of the target recognition grid template are acquired sequentially according to a set periodicity.
[0029] When a non-interested target enters the area of the target recognition grid template based on the real-time remote sensing image, and the non-interested target enters the reference area within a set time interval, and the non-interested target stays in the reference area for more than a set time threshold, then the non-interested target is changed to an interested target.

[0042] As can be seen from the above technical solutions, the technical solutions of the present invention have achieved the following beneficial effects:
[0043] This invention discloses a target identification method and system applicable to military management. The method includes: dividing the target identification grid template according to a three-dimensional entity model of the target identification area; acquiring standard remote sensing images corresponding to each target identification grid template at multiple time periods in a geographic information database, as well as the environmental features of each standard remote sensing image; for any target identification grid template, based on the behavioral characteristics of several targets of interest within the template, performing image fusion with the standard remote sensing image and its environmental features to obtain template images of each target of interest; constructing a convolutional neural network model, and training and optimizing the model based on the template images to obtain a target identification model; and identifying the targets of interest based on the target identification model.

[0058] Military target identification technology plays a crucial role in command and decision-making in military management. However, the speed and accuracy of target identification limit its application. Target identification speed depends on the algorithm's ability to process massive amounts of data, while accuracy depends on its classification capabilities. This invention aims to propose a target identification method and system suitable for military management. First, environmental characteristics of the target identification area are fused with behavioral characteristics of the target of interest and used as training data. Then, a convolutional neural network model is used to train the target identification model, improving accuracy while maintaining processing speed.
[0059] The target identification method applicable to military management described in this embodiment will be specifically introduced below with reference to the accompanying drawings.
[0060] like Figure 1 As shown, the method includes:
[0061] Step S102: Divide the target recognition mesh template according to the three-dimensional solid model of the target recognition area;
[0062] The purpose of dividing the target recognition grid template based on the 3D solid model is to find the locations where the target of interest is likely to pass through. For example, for targets of interest that are easy to hide during operation, the 3D solid model can discover multiple areas that are easy to hide in. These areas can be identified by finely dividing the recognition area and focusing on them. In addition, for some inconveniently observed recessed areas, planar observation can also be carried out by finely dividing the recognition area. In other words, the purpose of dividing the target recognition grid template is to track the target of interest better and more accurately.
[0063] As a specific implementation method, such as Figure 2 As shown, the process of dividing the target recognition mesh template in step S102 specifically includes the following steps: Step S1022: Based on the terrain distribution of the three-dimensional entity model, obtain several ordinary recognition areas and several key recognition areas for easily hidden targets; Step S1024: Divide any one of the key recognition areas into several planar areas using a plane as the dividing standard; Step S1026: Establish a spatial coordinate system for any one of the ordinary recognition areas and any one of the planar areas respectively. The origin of the spatial coordinate system can be uniformly selected as the center point of the area. Any one of the areas and the corresponding spatial coordinate system constitute the target recognition mesh template.
[0064] For a target recognition grid template, the observed content is relatively independent. Because it has an independent spatial coordinate system, the coordinates and position can be independently represented and displayed when determining the target of interest.
[0065] As an optional implementation, each target identification grid template is displayed independently in a planar mode in the military management decision-making center, and the real-time status of each target identification grid template is displayed synchronously to assist decision-makers in observation.
[0066] Step S104: Obtain the standard remote sensing images corresponding to each target identification grid template in the geographic information database for multiple time periods, as well as the environmental features of each standard remote sensing image;
[0067] This solution aims to fully utilize the environmental features of the target recognition area, matching these features with the behavioral features of the target of interest, and using this data to train a neural network target recognition model, thereby reducing the error caused by the environment of the recognition area in target recognition. Specifically, the process of acquiring environmental features is implemented based on the steps S1022-S1026 described above, such as... Figure 3 As shown, the following steps are used to obtain the reference points: Step S1042, based on the image content of the standard remote sensing image, determine multiple first reference points and at least one second reference point contained in the standard remote sensing image; wherein, the entire first reference point is displayed in the standard remote sensing image, and a portion of the second reference point is displayed in the standard remote sensing image; Step S1044, obtain the spatial coordinates of the multiple first reference points and the second reference points in the corresponding target recognition grid template, and associate the spatial coordinates. The purpose of selecting reference points is to provide a reference for the trajectory of the target when the entire target recognition grid template is used as the area of the target's movement, so that the trajectory can be planned according to the target's movement pattern. Optionally, reference points can be selected as prominent structures in the area, such as trees with significantly prominent shapes, rocks protruding from the ground, grassland, etc. Reference points can also be selected by performing image recognition on the standard remote sensing image and using the recognition results as reference points. Furthermore, in implementation, the spatial coordinates are associated by storing each spatial coordinate as a data group in the corresponding target recognition grid template, and highlighting each target recognition grid template independently in a planar mode in the decision center.
[0068] As another possible implementation method, such as Figure 5 As shown, the acquisition of the environmental features further includes the following steps: Step S1046: Determine the color features of the standard remote sensing image based on the time period and image content corresponding to the standard remote sensing image. Step S1048: Adjust the first reference point and the second reference point based on the color features. That is, as the season changes, the reference points are adjusted to some appearances that contradict the color features of that season. Of course, the reference points can also be set independently during exercises.
[0069] Step S106: For any target identification grid template, based on the behavioral characteristics of several targets of interest within the template, perform image fusion with the standard remote sensing image and its environmental features to obtain template images of each target of interest.
[0070] In this embodiment, image fusion involves predicting the motion trajectory of the target of interest. The predicted trajectory points are spatially hypothesized and fused with a standard remote sensing image and its environmental features to obtain a predicted image, i.e., a template image. Specifically, this fusion process is implemented based on steps S1042-S1044 described above, and the template image is as follows: Figure 4 As shown, the following steps are used to obtain the target recognition grid template: Step S1062, for any target recognition grid template, several motion trajectories of each target within the template are planned based on the content distribution of the standard remote sensing image and the movement patterns of the target of interest. Step S1064, for any motion trajectory, several reference trajectory points are selected based on the first and second reference points of the target recognition grid template, and the spatial coordinates of each reference trajectory point are determined in the target recognition grid template. Step S1066, for any reference trajectory point, the target of interest and the corresponding standard remote sensing image of the target recognition grid template are fused based on the spatial coordinates of the reference trajectory point to obtain a template image.
[0071] Step S108: Construct a convolutional neural network model and train and optimize the model based on the template images to obtain a target recognition model. During training, a number of template images are obtained based on the different targets of interest, the different target recognition grid templates they are in, and the different planned trajectories. These form a template image set, which is then divided into a training set and a validation set in a 7:3 ratio for model training. During model optimization, the recognition images corresponding to the real-time recognition results of the targets of interest are used as new training data to expand the template image set. The training set is updated in real time to optimize the target recognition model and improve the classification accuracy of the model.
[0072] Step S110: Identify the target of interest according to the target recognition model.
[0073] This invention applies a trained neural network model to a monitoring device, enabling the monitoring of targets of interest in each target identification grid template. Decision-makers can then make intelligent assisted decisions based on the identification results of the targets of interest.
[0074] As another possible implementation method, to ensure the accuracy of target identification, although targets of interest are given in advance, there are still some targets that are not in the target of interest list but exhibit behaviors that match those of the targets of interest. These targets also need to be given special attention; therefore, Figure 6As shown, the target recognition method disclosed in this embodiment of the invention further includes: step S1062', for any target recognition grid template, obtaining a reference region based on the selected first reference point and second reference point within it; wherein, the reference region is the largest closed region obtained by randomly connecting the first reference point and the second reference point as boundary points, and the area of the closed region is not less than half of the area of the target recognition grid template; step S1064', acquiring real-time remote sensing images of the target recognition grid template according to a set periodic sequence; step S1066', when a non-interested target is detected and identified entering the region of the target recognition grid template based on the real-time remote sensing image, and the non-interested target enters the reference region within a set time interval, and the non-interested target stays in the reference region for a time exceeding a set time threshold, then the non-interested target is changed to an interested target.
[0075] The target identification method proposed in this embodiment, applicable to military management, aims to address the shortcomings of existing military target identification methods, which are affected by the complex terrain and geomorphological environment where targets are hidden. These methods require the acquisition of a large number of images for comparison and calculation, resulting in high computational load and low identification accuracy when processing and analyzing such image data. The proposed method aims to meet the needs of military target identification while assisting military decision-making.
[0076] In embodiments of this application, an electronic device is also provided. This device includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the target identification method for military management disclosed in the above embodiments.

As defined herein, computer-readable media does not include temporary computer-readable media, such as modulated data signals and carrier waves.
[0078] These computer programs may also be loaded onto a computer or other programmable data processing equipment to cause a series of operational steps to be performed on the computer or other programmable equipment to produce a computer-implemented process, thereby providing instructions that execute on the computer or other programmable equipment for implementing the process. Figure 1 One or more processes and / or boxes Figure 1 The steps for the functions specified in one or more boxes can be implemented through different modules, corresponding to different method steps.
