[0036] The following is a description of the implementation of the present application by specific specific embodiments. People familiar with the technology can easily understand other advantages and effects of the present application from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0037] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0038] like Figure 1 , Figure 2 As shown, an embodiment of the present invention discloses a method for analyzing the use status of a homestead, and the method comprises the following steps:

[0039] A plurality of first high-definition images of a first target homestead in the analysis area and a plurality of second high-definition images of a plurality of second target homesteads similar to the first target homestead are photographed by a drone; wherein the first high-definition images are photographed at different angles from each other, and the second high-definition images are photographed at different angles from each other;

[0040] The ground terminal extracts the first building outline features of the first target homestead based on each of the first high-definition images, and constructs a first three-dimensional structure of the first target homestead based on the first building outline features;

[0041] The ground terminal extracts the second building outline features of each second target homestead based on each second high-definition image, inputs the first three-dimensional structure and the second building outline features into a three-dimensional structure restoration model based on artificial intelligence, and obtains a predicted second three-dimensional structure;

[0042] The structural deviation value between the second three-dimensional structure and the first three-dimensional structure is calculated. If the structural deviation value is lower than the deviation threshold, the first target homestead is determined to be in use; otherwise, the first target homestead is determined to be idle.

[0043] Compared with the traditional method of determining by human visits, the present invention uses a drone to shoot high-definition images of the target homestead that needs to be analyzed for usage status, and analyzes the usage status of the homestead buildings extracted from the high-definition images. Specifically, the drone shoots several first high-definition images of the first target homestead in the analysis area, and several second high-definition images of several second target homesteads similar to the first target homestead. The first high-definition image and the second high-definition image are multiple images taken from different shooting angles, which is conducive to the subsequent generation of accurate three-dimensional structures of the homestead. The ground terminal located on the ground and operated by relevant personnel receives the first high-definition image and the second high-definition image, and extracts the first building outline features of the buildings (houses, walls, etc.) in the first target homestead from each first high-definition image, and the first three-dimensional structure of the first target homestead can be constructed based on this. The first three-dimensional structure reflects the real three-dimensional structural state of each building in the first target homestead. At the same time, the contour features of the buildings of each second target homestead are extracted from each second high-definition image, and all the contour features are integrated into the second building contour features; the first three-dimensional structure and the second building contour features are input into the three-dimensional structure restoration model based on artificial intelligence, and the three-dimensional structure restoration model predicts the second three-dimensional structure of each building of the first target homestead under the guidance of the second building contour features. The second three-dimensional structure reflects the three-dimensional structural state that the first target homestead should have under normal use and maintenance. Finally, by comparing the structural deviation value between the real first three-dimensional structure and the predicted second three-dimensional structure, it is possible to determine whether the first target homestead is in use or idle.

[0044] Therefore, the solution of the present invention uses the cooperation between the drone and the ground terminal to achieve accurate judgment of the usage status of the homestead, without the need to configure a large number of visiting manpower, which can significantly improve the analysis efficiency of the usage status of the homestead.

[0045] It should be noted that the present invention does not specifically limit the selection of the drone, the configuration of the camera, and the communication and control method between the drone and the ground terminal.

[0046] In some embodiments, before taking a plurality of first high-definition images of a first target homestead within the analysis area by using a drone, the method further includes:

[0047] The third high-definition image of the analysis area is taken by the drone, and the ground terminal determines each homestead area from the third high-definition image, and determines and obtains the regional high-definition image corresponding to each homestead area in the third high-definition image;

[0048] Furthermore, the ground terminal performs color quantity analysis on the regional high-definition images of each of the homestead areas, and determines each of the first target homesteads based on the obtained color quantities.

[0049] In an embodiment of the present invention, when the analyst arrives at the analysis area, the drone is released, and the drone first takes a third high-definition image (such as a panoramic image) of the entire analysis area and transmits it to the ground terminal. The ground terminal first determines each homestead area from it, and determines the regional high-definition image corresponding to each homestead area in the third high-definition image. Then, since when the homestead is in use, there will be objects such as clothes, food, and parked cars, and the colors of these objects are usually different and relatively bright compared to the building itself. Therefore, the number of colors of the high-definition images of each area is analyzed, and the first target homestead is determined from each homestead area based on the number of colors obtained by the analysis. Specifically, when the number of colors is lower than the color number threshold, it can be preliminarily determined that the homestead is in an idle state, and it is used as the first target homestead for subsequent targeted analysis; otherwise, it can be preliminarily determined that the homestead is in use and is not used as the first target homestead.

[0050] In some embodiments, the plurality of first high-definition images of a first target homestead in the analysis area and the plurality of second high-definition images of a plurality of second target homesteads adjacent to the first target homestead taken by the drone include:

[0051] deriving the type of buildings in the analysis area based on the third high-definition image, determining the building height according to the type, and determining a group of shooting angles according to the building height, specifically, the angle span range corresponding to the group of shooting angles is inversely proportional to the building height;

[0052] The drone is controlled to shoot several first high-definition images of a first target homestead within the analysis area and several second high-definition images of several second target homesteads adjacent to the first target homestead according to the group of shooting angles.

[0053] In the embodiment of the present invention, by shooting the image of the target homestead at different angles, it is helpful to accurately analyze and obtain the three-dimensional structure data of the buildings in the target homestead, and then it is helpful to accurately construct the first three-dimensional structure of each building in the first target homestead. At the same time, the determination of the shooting angle should also be appropriate, not too much or too little.

[0054] In view of the above requirements, the present invention first analyzes the type of building in the analysis area based on the third high-definition image obtained by the aforementioned shooting, and then determines the building height according to the building type. For example, if the type of building analyzed is a bungalow, the building height is determined to be 5 meters, and if the type of building analyzed is a building, the building height is determined to be 10 meters, etc., which can be determined by the building type-height comparison table. Furthermore, according to the aforementioned determined building height, a group of shooting angles are determined, and specifically, the angle span range corresponding to the group of shooting angles is inversely proportional to the building height, that is, the higher the height of the building in the analysis area, the easier it is to capture the three-dimensional structure data of the building, and the smaller the difference between the maximum angle value and the minimum angle value of the group of shooting angles is set at this time; and the lower the height of the building in the analysis area, due to the insufficient building height, it is more difficult to capture the clear three-dimensional structure data of the building, and the larger the difference between the maximum angle value and the minimum angle value of the group of shooting angles is set at this time, so that the calculation deviation caused by the visual error can be overcome (generally lower than the actual height of the building).

[0055] It should be noted that the number of angles in the group of shooting angles can also be adjusted accordingly, that is, the number of angles corresponding to the group of shooting angles is inversely proportional to the height of the building. Such a setting is also conducive to extracting a more accurate three-dimensional structure of the building.

[0056] In some embodiments, a plurality of second high-definition images of a plurality of second target homesteads similar to the first target homestead in the analysis area are taken by a drone, including:

[0057] deriving a first number of other homesteads with similar building types to the first target homestead within the analysis area based on the third high-definition image analysis, and determining a second number based on the first number;

[0058] Determine the second number of the second target homesteads adjacent to the first target homestead within the analysis area.

[0059] In an embodiment of the present invention, the second building outline feature extracted from the second target homestead can be used to assist the three-dimensional structure restoration model in "restoring" the first three-dimensional structure to the three-dimensional structure state that the first target homestead should have under normal use and maintenance. In order to ensure the accuracy of the second three-dimensional structure predicted by the three-dimensional structure restoration model, it is necessary that the second building outline feature contains an appropriate number of outline features of the second target homestead. In this regard, the present invention adopts the following scheme:

[0060] The third high-definition image is continuously used to analyze and obtain the first number of other homesteads with similar building types to the first target homestead. For example, if the building of the first target homestead is a bungalow, other homesteads with the same bungalow type are determined from the third high-definition image, and then the second number is determined based on the first number of these other homesteads. Then, the second number of second target homesteads with similar characteristics to the first target homestead is screened around the first target homestead.

[0061] Therefore, by analyzing the number of other homesteads with the same type of buildings in the analysis area, the number of second target homesteads that should be screened for generating the second building outline features is determined, thereby ensuring that the second building outline features contain outline features of an appropriate number of second target homesteads, which can not only ensure the accuracy of the prediction results of the three-dimensional structure restoration model, but also reduce the analysis and calculation load of the three-dimensional structure restoration model and improve the prediction efficiency.

[0062] It should be noted that the second number may be a value obtained by multiplying the first number by a conversion coefficient, and the conversion coefficient should be a value less than 1.

[0063] In some embodiments, the three-dimensional structure restoration model is constructed based on a large model, and the large model is fine-tuned using small sample training data to obtain the three-dimensional structure restoration model.

[0064] In the embodiment of the present invention, with the advancement of science and technology, large models such as ChatGPT, KIMI, and Tongyi Qianwen have developed rapidly. These large models have more powerful "intelligent" analysis capabilities and have achieved significant progress in text understanding, translation, writing, and other aspects. The present invention constructs the above-mentioned three-dimensional structure restoration model based on these large models. Specifically, small sample training data is obtained in advance. The small sample training data contains a certain amount of training data. These training data include various structural form data of various types of buildings. These small sample training data are used to fine-tune the existing large models, and a three-dimensional structure restoration model suitable for restoring the three-dimensional structure of the building in the present invention can be obtained.

[0065] Among them, the small sample in the present invention is relative to the training sample of the vertical model. The vertical model needs to be built using a specific algorithm and trained using a large amount of training data. The present invention adopts a general large model. The large model does not need to be built, and it has been fully trained during use. At this time, only less training data, that is, a small sample, is needed to train its prediction and analysis capabilities in certain aspects.

[0066] In some embodiments, calculating the structural deviation value between the second three-dimensional structure and the first three-dimensional structure includes:

[0067] Decomposing the second three-dimensional structure and the first three-dimensional structure into a plurality of second three-dimensional substructures and a plurality of first three-dimensional substructures according to building units;

[0068] Determine the corresponding second three-dimensional substructure and the first three-dimensional substructure based on the same position principle, and calculate the first structural deviation value of the second three-dimensional substructure and the first three-dimensional substructure;

[0069] The first structural deviation values ​​are fused and calculated to obtain a second structural deviation value.

[0070] In the embodiment of the present invention, the second three-dimensional structure and the first three-dimensional structure obtained above contain multiple single buildings, such as the main house, the wing house, etc., so the present invention first splits the single building, that is, obtains multiple second three-dimensional substructures and first three-dimensional substructures, and the second three-dimensional substructures and the first three-dimensional substructures in the same position constitute a group of comparison data. The first structural deviation values ​​between the second three-dimensional substructures and the first three-dimensional substructures in each group of comparison data are calculated respectively, and then the first structural deviation values ​​corresponding to all the single buildings are fused and calculated, that is, the second structural deviation value that can characterize the structural deviation value between the second three-dimensional structure and the first three-dimensional structure is obtained.

[0071] The fusion calculation may be a weighted average, wherein the weight of the main house is higher than that of the wing room, and the weight of the wing room is higher than that of the roofless house, etc. The above weight relationship is only an example, and may be determined according to the number of building types included in the homestead, and the weight of each type of building may be pre-specified.

[0072] like Figure 3 As shown, the embodiment of the present invention further discloses a homestead use status analysis system, the system comprising a processing device and a storage device, the processing device retrieves and executes the computer code in the storage device to implement the following method steps:

[0073] A plurality of first high-definition images of a first target homestead in the analysis area and a plurality of second high-definition images of a plurality of second target homesteads similar to the first target homestead are photographed by a drone; wherein the first high-definition images are photographed at different angles from each other, and the second high-definition images are photographed at different angles from each other;

[0074] The ground terminal extracts the first building outline features of the first target homestead based on each of the first high-definition images, and constructs a first three-dimensional structure of the first target homestead based on the first building outline features;

[0075] The ground terminal extracts the second building outline features of each second target homestead based on each second high-definition image, inputs the first three-dimensional structure and the second building outline features into a three-dimensional structure restoration model based on artificial intelligence, and obtains a predicted second three-dimensional structure;

[0076] The structural deviation value between the second three-dimensional structure and the first three-dimensional structure is calculated. If the structural deviation value is lower than the deviation threshold, the first target homestead is determined to be in use; otherwise, the first target homestead is determined to be idle.
