Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
At present, a method which is not represented is adopted for processing the moving military target, or peripheral colors are selected for simple blurring processing. Currently, the mobile military target recognition technology focuses on the research of high-resolution remote sensing images, aims at accurately searching for mobile military targets and recognition models, usually uses a deep learning method to train samples, carries out global classification, and focuses on classification accuracy and recall. The training sample set is classified transversely according to the model number more, and the condition of longitudinal classification according to the resolution and the coordinates does not exist.
The implementation of the above technique has the following drawbacks: 1) Most of research oriented objects based on deep learning military target recognition are concentrated on high-resolution images, and the resolution of public Internet remote sensing images can recognize mobile military targets from 8-18 levels, so that the current target recognition method is not suitable for the safety guarantee of a multi-scale Internet remote sensing image map; 2) The current research search target speed depends on the depth of a search algorithm and the complexity of a neural network structure, the more the accuracy or recall rate is pursued, the slower the speed is, other information assistance such as coordinates are not considered, and the target search recognition speed is low because the target is classified only by using an optical remote sensing deep learning method and the speed lifting space is limited; 3) The traditional safety guarantee method is too coarse, only the existence of a mobile military target is simply wiped off, and the simple blurring treatment cannot completely cover traces. The application replaces the movable military target with the civil target, and greatly weakens the trace of the traditional camouflage method, thereby achieving the purpose of safety guarantee.
The application disguises or covers the mobile military targets, so that the operation objects can be common airplanes and ships with higher similarity, if the coverage rate of the mobile military targets is pursued, the mobile military target identification technology needs to accurately identify the common targets and the military targets, and thus, the sample and the classification are relatively complex, and the accuracy is also reduced.
In order to facilitate understanding of the present embodiment, the following describes embodiments of the present application in detail.
Embodiment one:
fig. 1 is a flowchart of a geographic information security assurance method for an electronic map according to an embodiment of the present application.
Referring to fig. 1, the electronic map of the present application is an electronic map for internet images, and the method includes the steps of:
step S101, determining the position of a risk area;
in particular, risk areas include, but are not limited to, airports and sea surfaces, where the location of the risk area, i.e., the location of the airport and the location of the sea surface, is determined; the functional attribute of the mobile military target can be determined as a military machine according to the position of the airport; the functional attribute of the mobile military target can be determined to be a warship according to the sea surface position.
The position of the airport and the position of the sea surface adopt two modes of accurate positioning and quick positioning. The accurate positioning is to set a threshold value as a radial searching area according to the attribute (military machine or warship) of the military target set by taking the mobile military target of the military target set as the center, namely the position of an airport and the position of the sea surface. The target search areas may overlap, so that each search area does not need to be traversed, only a union is selected first, and the position of the risk area is determined according to the union.
The quick positioning is to acquire a first-level image, wherein the first-level image comprises a plurality of slices, the first-level image with the smallest scale is selected, each operation object is a slice, and the first-level image is extracted through a quick unsupervised classification algorithm to obtain a cement floor and a water body; the reflectivity can be inverted by using the images, and the cement ground and the water body can be extracted according to the difference of the reflectivities; and deleting finely-crushed plaques smaller than the set area according to the area size, wherein the left plaques are the position of an airport and the position of the sea surface. The slice with the smallest scale is easily distinguished even if the scale is small because the area of the airport and the sea surface is relatively large compared with other ground objects (such as buildings); if starting from a large scale, there are many finely divided spots. The greater the number of spots, the slower the speed. Conversely, if it is possible to determine which areas are airports and sea surfaces at a small scale, camouflage can be performed directly in subsequent levels of images.
Step S102, judging whether a mobile military target is contained in the risk area;
here, the location of the airport and the location of the sea surface are identified by a deep learning algorithm as to whether it is a civil moving target, and if not, it is considered as a moving military target.
The mobile military target is a military machine or warship. Because the images of the mobile military targets are taken as samples and have confidential risks, the images cannot be used by enterprises or individuals, and meanwhile, in order to ensure coverage, judgment is based on whether the images are civil targets (civil aircraft ships) or not, and the images are considered to be the mobile military targets, so that the images need to be processed for safety guarantee.
Step S103, if yes, recording the range of the risk area;
step S104, determining the attribute of the mobile military target; wherein the attributes include a functional attribute and a quantity attribute;
step S105, performing covering processing and smoothing processing according to the attribute of the mobile military target.
Here, the above steps are repeated for each stage of image until all moving military targets in the image pass through the security guarantee.
Further, step S101 includes the steps of:
step S201, determining a military target set;
step S202, setting a searching area with a threshold value as a radius according to the attribute of a mobile military target taking the mobile military target of the military target set as the center;
step S203, determining the position of the airport and the position of the sea surface according to the search area.
Further, step S101 includes the steps of:
step S301, acquiring a primary image, wherein the primary image comprises a plurality of slices;
step S302, extracting the first-level image through a rapid non-supervision classification algorithm to obtain a cement floor and a water body;
step S303, deleting the finely divided plaque smaller than the set area according to the size of the area, and determining the position of the airport and the position of the sea surface according to the left plaque.
Further, step S105 includes the steps of:
step S401, when the quantity attribute of the mobile military targets is the target group, replacing the mobile military targets with the civil target group;
step S402, when the quantity attribute of the mobile military target is a single target, replacing the mobile military target with a civil single target;
in step S403, smoothing processing is performed around the rectangular range of the civil target group or the civil single target.
Further, the rectangular range of the civil target group or the civil single target is equal to the outline range of the mobile military target, and the water body or the cement floor is filled between the rectangular range and the outline range according to the functional attribute.
Here, the material of the risk area filled between the rectangular range and the outline range according to the functional attribute is not limited to the water body and the cement floor, but may be other materials.
The embodiment of the application provides a geographic information security guarantee method of an electronic map, which comprises the following steps: determining the position of a risk area; judging whether the risk area contains a mobile military target or not; if yes, recording the range of the risk area; determining attributes of a mobile military target; performing covering treatment and smoothing treatment according to the attribute of the mobile military target; the target searching and identifying speed is high, the attribute of the mobile military target is subjected to covering treatment and smoothing treatment, and the information safety is ensured.
