[0001] The present invention relates to the technical field of damaged area survey, and in particular to a method and system for surveying damaged areas caused by geological disasters. Background Art

[0002] The occurrence of geological disasters will have a great negative impact on people's lives, so it is necessary to monitor them. According to the aerial photography data corresponding to the geological disaster area, the disaster area is divided into mild areas and severe areas, so as to carry out surveys from various angles in each area, confirm the damaged areas corresponding to each mild area and the damaged areas corresponding to each severe area, and realize the correct and accurate identification of the damaged areas in the geological disaster area, thereby providing effective data reference for subsequent disaster maintenance or disaster risk prediction.

[0003] Prior art, such as the invention patent application with publication number CN112183418B, discloses a method and system for surveying damaged areas caused by geological disasters. The method comprises: obtaining satellite image information of a target damaged area; determining location information within the target damaged area where additional image acquisition is required via drone, and transmitting the location information to a related drone for additional image acquisition of the area corresponding to the location information; performing three-dimensional modeling based on the satellite image information and the additional image information to form a three-dimensional model of the target damaged area; and determining the area and volume of the collapse / landslide body and the target remediation area within the target damaged area based on the three-dimensional model. Satellite image information of the damaged area is obtained from historical satellite photos, and drones are used to supplement unclear areas of the satellite image information based on the acquired satellite image information, thereby making the situation in the damaged area clearer and allowing users to more intuitively understand the specific situation of the damaged area.

[0004] Regarding the above scheme, there are the following technical problems: the above invention mainly collects supplementary data on unclear areas in satellite image information to make the situation in the damaged area clearer, so that users can understand the specific situation of the damaged area more intuitively. It does not divide the area from the perspective of preliminary collection of panoramic images corresponding to the geological disaster area, and thus fails to equip different areas with efficient and suitable survey equipment. There is a solid-state thinking of only surveying obvious damaged areas, which may lead to missed detection of hidden damage in geological disaster areas, leaving safety hazards, and unable to determine the true and comprehensive damaged area in the geological disaster area, and unable to achieve effective and accurate survey of the geological disaster damaged area. Summary of the Invention

[0005] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide a method and system for surveying damaged areas caused by geological disasters.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions: The present invention provides a method for surveying damaged areas of geological disasters, including: Step 1, disaster area division: preliminary aerial photography of the geological disaster area, obtaining aerial photography data corresponding to the geological disaster area, and then analyzing to obtain various severe areas and various mild areas.

[0007] Step 2: Survey and analysis of mild areas: Based on the geology corresponding to the geological disaster area, the survey equipment corresponding to each mild area is screened, and the survey anomaly data set corresponding to each mild area is analyzed to determine whether there is a new damage form in each mild area. If there is a new damage form in each mild area, it is recorded as a mild target area. The survey data corresponding to the new damage form of each mild target area is obtained to determine the damaged area corresponding to each mild target area.

[0008] Step 3. Survey and analysis of severe areas: By analyzing the application survey equipment corresponding to each severe area, and based on the application survey equipment, obtain the corresponding detection data between each severe area and the adjacent area, analyze whether tail-related damage will be formed between each severe area and the adjacent area, and confirm the damaged area corresponding to each severe area.

[0009] Step 4: Early warning: Issue an early warning when a new damage pattern appears in a mild area or when tail-related damage forms between a severe area and the adjacent area.

[0010] In a second aspect, the present invention provides a system for surveying damaged areas of geological disasters, including: a disaster area division module for obtaining aerial photography data corresponding to geological disaster areas, and then analyzing to obtain various severe areas and various mild areas.

[0011] The light area survey and analysis module is used to screen the survey equipment corresponding to each light area, and analyze the survey anomaly data set corresponding to each light area to determine whether there is a new damage form in each light area. If there is a new damage form in each light area, it will be recorded as a light target area, and the survey data corresponding to the new damage form of each light target area will be obtained to determine the damage area corresponding to each light target area.

[0012] The heavy area survey and analysis module is used to analyze the application survey equipment corresponding to each heavy area, obtain the corresponding detection data between each heavy area and the adjacent area, analyze whether tail-related damage will be formed between each heavy area and the adjacent area, and confirm the damaged area corresponding to each heavy area.

[0013] The early warning terminal is used to issue early warning prompts when new damage forms appear in a light area or when tail-related damage forms between a heavy area and the adjacent area.

Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0019] Figure 1 The figure is a schematic flow chart of the steps for implementing the method of the present invention.

[0020] Figure 2 This is a schematic diagram of the system structure connection of the present invention. DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1 As shown, a method for surveying damaged areas caused by geological disasters includes: Step 1, disaster area division: preliminary aerial photography of the geological disaster area, obtaining aerial photography data corresponding to the geological disaster area, and then analyzing to obtain various severe areas and various mild areas.

[0023] It should be noted that the pit depression data and the debris accumulation data are the pit depression depth and the debris accumulation height; they are extracted from the disaster panoramic image using stereo vision technology.

[0024] In a specific embodiment of the present invention, the analysis obtains various severe areas and various mild areas, and the specific analysis process is as follows: satellite remote sensing technology is used to perform preliminary aerial photography of the geological disaster area to obtain a disaster panoramic image corresponding to the geological disaster area, and the pit depression data and scattered debris accumulation data corresponding to each position are extracted from the disaster panoramic image. The pit depression data corresponding to each position is compared with the set reference pit depression data, and the scattered debris accumulation data corresponding to each position is also compared with the preset reference scattered debris accumulation data. If the pit depression data corresponding to a certain position is greater than or equal to the set reference pit depression data, or the scattered debris accumulation data corresponding to a certain position is greater than or equal to the preset reference scattered debris accumulation data, the area corresponding to the position is recorded as a severe area, otherwise, it is recorded as a mild area, and so on to obtain various severe areas and mild areas corresponding to the geological disaster area.

[0025] It should be noted that the area corresponding to this position is recorded as a heavy area: the position is determined based on the depth of the pit depression or the height of the scattered objects, and the area is recorded as a heavy area based on the cross-section of the pit or the area corresponding to the scattered objects. The remaining area after removing the heavy area is recorded as a light area.

[0026] It should be noted that the reference pit depression data and reference scattered debris accumulation data are set by professional surveyors; the reference pit depression data is a reference value used to determine and distinguish the degree of disaster impact suffered by various locations in the region under geological disasters, and the role of the reference scattered debris accumulation data is the same, so it will not be repeated here.

[0027] Conduct preliminary aerial photography of the geological disaster area to obtain the corresponding aerial photography data of the geological disaster area, and then analyze to obtain the severe areas and mild areas, so as to realize the corresponding division of the geological disaster area, conduct efficient surveys from various angles of the area, and ensure that the geological disaster area receives a comprehensive damage survey.

[0028] Step 2: Survey and analysis of mild areas: Based on the geology corresponding to the geological disaster area, the survey equipment corresponding to each mild area is screened, and the survey anomaly data set corresponding to each mild area is analyzed to determine whether there is a new damage form in each mild area. If there is a new damage form in each mild area, it is recorded as a mild target area. The survey data corresponding to the new damage form of each mild target area is obtained to determine the damaged area corresponding to each mild target area.

[0029] It should be noted that the crack data and soil mound data refer to the crack opening and soil mound height, etc.

[0030] It should be noted that the disaster sets mapped in each underground area are disaster sets that occurred simultaneously with the geological destruction in history.

[0031] In a specific embodiment of the present invention, the screening obtains the survey equipment corresponding to each mild area, and the specific screening process is as follows: based on the geological structure corresponding to the geological disaster area, and obtaining the micro-feature information corresponding to each mild area from the disaster panoramic image, including crack data and mound data, the crack data and mound data corresponding to each mild area are compared with the crack data and mound data of the underground mapping disaster set corresponding to the geological disaster stored in the database. If the crack data and mound data corresponding to a mild area are the same as the crack data and mound data of the underground mapping disaster corresponding to the geological disaster stored in the database, then the underground mapping disaster is determined to be the mapped underground disaster corresponding to the current mild area, and the historical survey equipment set used in the survey corresponding to the underground mapping disaster is obtained from the database, and the historical survey equipment set corresponding to the underground mapping disaster is used as the survey equipment corresponding to the mild area, so as to obtain the survey equipment corresponding to each mild area through screening.

[0032] In a specific embodiment of the present invention, the analysis obtains a set of survey anomaly data corresponding to each mild area. The specific analysis process is as follows: based on the survey equipment corresponding to each mild area, underground exploration corresponding to each mild area is performed, and according to the underground survey feedback obtained when the survey equipment detects the underground, underground exploration data corresponding to each mild area is obtained, including feedback type 1 data, feedback type 2 data, feedback type 3 data and feedback type 4 data.

[0033] According to the underground exploration data corresponding to each mild area, the characteristic values ​​of the first-category feedback data and the second-category feedback data corresponding to each mild area are obtained and recorded as μ q and μ1 q , q is the number of each mild area, q = 1, 2, ..., ..., w, w is any integer greater than 2, the characteristic value of the feedback type 1 data and the characteristic value of the feedback type 2 data corresponding to each mild area are imported into the underground anomaly assessment model: Among them D q is the damaged characteristic value corresponding to the qth light area, L″ and L″′ are the upper limit and lower limit of the damaged characteristic value corresponding to the set underground exploration data, respectively.

[0034] Based on the analysis of the underground exploration data corresponding to each mild area, the characteristic values ​​of the three types of feedback data and the four types of feedback data corresponding to each mild area are obtained and recorded as H q and H1 q The characteristic values ​​of the three types of feedback data and the four types of feedback data corresponding to each mild area are imported into the underground state assessment model: where δ q is the state characteristic value corresponding to the qth mild area, S″ and S″′ are the upper limit and lower limit of the state characteristic value corresponding to the set underground exploration data respectively.

[0035] The survey anomaly data set corresponding to each mild area is constructed by feedback type 1 data eigenvalue, feedback type 2 data eigenvalue, damaged eigenvalue, feedback type 3 data eigenvalue, feedback type 4 data eigenvalue and status eigenvalue.

[0036] It should also be noted that if the first type of feedback data obtained when the survey equipment detects the underground is abnormal wave data, then the feedback survey equipment corresponding to the survey of each mild area is a seismometer; if the second type of feedback data obtained when the survey equipment detects the underground is abnormal resistivity data, then the feedback survey equipment corresponding to the survey of each mild area is a resistivity sounder; if the third type of feedback data obtained when the survey equipment detects the underground is abnormal natural potential data, then the feedback survey equipment corresponding to the survey of each mild area is a natural potential logging instrument; if the fourth type of feedback data obtained when the survey equipment detects the underground is magnetic gradient data, then the feedback survey equipment corresponding to the survey of each mild area is a proton magnetometer.

[0037] It should also be noted that the upper and lower limits of the damaged characteristic values ​​corresponding to the underground exploration data, and the upper and lower limits of the status characteristic values ​​corresponding to the underground exploration data are set by professional surveyors. The upper limit of the damaged characteristic value corresponding to the underground exploration data is a reference value for determining whether there is underground damage in the current mild area. The lower limit of the damaged characteristic value corresponding to the underground exploration data, and the upper and lower limits of the status characteristic value corresponding to the underground exploration data have the same function, so they will not be repeated.

[0038] It should also be noted that if the current feedback type 1 data corresponding to each mild area is abnormal wave data: the abnormal wave data corresponding to each mild area is compared with the wave data threshold stored in the database. If the abnormal wave data corresponding to a mild area is less than the wave data threshold stored in the database, the feedback type 1 data characteristic value corresponding to each mild area is recorded as -1, otherwise it is recorded as 1. Similarly, the feedback type 1 data characteristic value corresponding to each mild area is obtained. Similarly, the feedback type 2 characteristic value, feedback type 3 characteristic value and feedback type 4 characteristic value corresponding to each mild area can be obtained, so they are not repeated here.

[0039] In a specific embodiment of the present invention, the specific judgment process of judging whether each light area has a new damage form is as follows: based on the damaged characteristic value and state characteristic value corresponding to each light area, when D q =1∧δ q =1, the light area numbered q is recorded as having no underground geological damage, and it is determined that there is no new damage form in the light area;

[0040] When D q =0∧δ q =0, D q =1∧δ q =0, D q =0∧δ q =1 or D q =-1∧δ q = -1, the light area numbered q is recorded as having underground geological damage, and it is determined that the light area has a new damage form, and the light area is recorded as a light target area.

[0041] In a specific embodiment of the present invention, the specific analysis process for determining the damaged area corresponding to each light target area is as follows: further survey is performed on the light area with new damage forms, and based on the further underground survey signal feedback of the underground stage depth surface corresponding to each light target area surveyed by the survey equipment, the survey data of the underground stage depth surface corresponding to each light target area is obtained, that is, the underground resistance data and the underground resistance data.

[0042] The underground resistance data of the underground stage depth surface corresponding to each light target area is compared with the reference underground resistance data stored in the database. At the same time, the underground resistance data of the underground stage depth surface corresponding to each light target area is also compared with the reference underground resistance data stored in the database. If the underground resistance data of the underground stage depth surface corresponding to a light target area is less than the reference underground resistance data stored in the database, or the underground resistance data of the underground stage depth surface corresponding to a light target area is greater than the reference underground resistance data stored in the database, then it is determined that the underground stage depth surface corresponding to the current light target area is the damaged area corresponding to the light target area, and so on, to obtain the damaged area corresponding to the light target area.

[0043] It should be noted that if further survey signal feedback is obtained based on the survey equipment surveying the underground stage depth surface corresponding to each light target area, the underground resistance data of the underground stage depth surface corresponding to each light target area is the shear strength, and the underground resistance data is the resistance value, then the feedback survey equipment of the underground stage depth surface corresponding to each light target area is the static penetration instrument.

[0044] It should be noted that the reference underground resistance data and reference underground resistance data are set by professional surveyors; the reference underground resistance data and reference underground resistance data are reference values ​​for determining whether underground damage areas appear in light target areas.

[0045] According to the geology corresponding to the geological disaster area, the survey equipment corresponding to each mild area is screened and analyzed to obtain the survey anomaly data set corresponding to each mild area. It is judged whether there is a new damage form in each mild area and the damaged area corresponding to each mild target area is determined to avoid reconstruction in the geological disaster risk area, reduce the risk of future disasters, and provide effective data reference support for subsequent disaster maintenance, so that the geological disaster area can obtain a truly comprehensive summary of the damaged area and ensure the effectiveness of damage survey in the geological disaster area.

[0046] Step 3. Survey and analysis of severe areas: By analyzing the application survey equipment corresponding to each severe area, and based on the application survey equipment, obtain the corresponding detection data between each severe area and the adjacent area, analyze whether tail-related damage will be formed between each severe area and the adjacent area, and confirm the damaged area corresponding to each severe area.

[0047] In a specific embodiment of the present invention, the analysis obtains the application survey equipment corresponding to each severe area, and the specific analysis process is as follows: obtain the basic function characteristics of the damaged position corresponding to each severe area before the geological disaster occurs, that is, the functional function type, and compare the functional function type of the damaged position corresponding to each severe area with the functional function type set corresponding to each functional survey equipment applied under geological disasters stored in the database. If the functional function type of the damaged position corresponding to each severe area is within the functional function type set corresponding to a functional survey equipment applied under geological disasters stored in the database, then the functional survey equipment is used as the application survey equipment corresponding to the severe area. By comparing and analogizing, the application survey equipment corresponding to each severe area is obtained.

[0048] In a specific embodiment of the present invention, the analysis of whether tail-associated damage is formed between each severe area and the adjacent area is carried out as follows: based on the use of survey equipment, each severe area and the adjacent area are surveyed, and according to the survey equipment in data feedback during the survey, the corresponding detection data between each severe area and the adjacent area are obtained, including continuous low-reflection data, seismic wave data and distortion data, and the corresponding detection data between each severe area and the adjacent area are imported into the regional tail-associated damage assessment model, and then the damage series result value corresponding to each severe area and the adjacent area is analyzed to obtain. If the damage series result value corresponding to the severe area and the adjacent area is 1, it is determined that tail-associated damage is formed between the severe area and the adjacent area, and an in-depth survey is performed under the tail-associated damage between the severe area and the adjacent area. If the damage series result value corresponding to the severe area and the adjacent area is 0, it is determined that tail-associated damage is not formed between the severe area and the adjacent area, thereby analyzing whether tail-associated damage is formed between each severe area and the adjacent area.

[0049] Damage assessment model via regional tail correlation:

[0050] where ψ z is the damage series result value corresponding to the zth severe area and the adjacent area, z is the number of each severe area, z = 1, 2, ..., ..., x, x is any integer greater than 2, y′ is the set reference low reflection data, t′ is the set reference seismic wave data, u′ is the set reference distortion data, y z is the low reflection data corresponding to the zth severe area and the adjacent area, t z is the corresponding shock wave data between the zth severe area and the adjacent area, u z is the distortion data corresponding to the zth severe area and the adjacent area, and p is the set series damage value of the tail of the reference area.

[0051] It should be noted that, if the continuous low-reflection data between each heavy area and the adjacent area measured by the survey equipment is the continuous low-reflection frequency, then the survey equipment in data feedback during the survey between each heavy area and the adjacent area is the geological radar; if the seismic wave data between each heavy area and the adjacent area measured by the survey equipment is the seismic wave velocity, then the survey equipment in data feedback during the survey between each heavy area and the adjacent area is the sonic logging instrument; if the distortion data between each heavy area and the adjacent area measured by the survey equipment is the waveform distortion rate, then the survey equipment in data feedback during the survey between each heavy area and the adjacent area is the oscilloscope survey.

[0052] It should also be noted that the reference continuous low-reflection data, reference seismic wave data, reference distortion data and reference area tail series damage value are set by professional surveyors; the reference continuous low-reflection data is a reference value used to determine whether there is tail series damage between each severe area and the adjacent area; the reference seismic wave data, reference distortion data and reference area tail series damage value have the same function, so they will not be repeated.

[0053] In a specific embodiment of the present invention, the confirmation obtains the damaged area corresponding to each severe area, and the specific analysis process is as follows: based on the damage series result value corresponding to each severe area and the adjacent area, and counting the damage series result value output of each severe area and the adjacent area as 1, the remaining area between each severe area and the adjacent area is recorded as the series damaged area, and the series damaged area corresponding to each severe area is obtained comprehensively, and each severe area with the series damaged area is connected with the adjacent area to obtain a complete damaged area, thereby confirming the damaged area corresponding to each severe area.

[0054] By analyzing the application survey equipment corresponding to each severe area and obtaining the corresponding detection data between each severe area and the adjacent area, it is analyzed whether tail-related damage will be formed between each severe area and the adjacent area, and the damaged area corresponding to each severe area is confirmed. The probability of missing detection of hidden damaged areas in geological disaster areas is reduced, the remaining damage safety hazards in geological disaster areas are reduced, and effective accurate survey of geological disaster damaged areas is achieved.

[0055] The database is used to store aerial photography data, micro-feature information, crack data and mound data of each underground mapping disaster set, underground exploration data, survey data, reference resistance data, reference resistance data, detection data and basic action characteristics.

[0056] Step 4: Early warning: Issue an early warning when a new damage pattern appears in a mild area or when tail-related damage forms between a severe area and the adjacent area.

[0057] See also Figure 2As shown, a geological disaster damaged area survey system includes a disaster area division module, a light area survey and analysis module, a heavy area survey and analysis module, an early warning terminal and a database.

[0058] The disaster area division module is connected to the light area survey and analysis module, the heavy area survey and analysis module and the database respectively; the light area survey and analysis module is connected to the early warning terminal and the database respectively; and the heavy area survey and analysis module is connected to the early warning terminal and the database respectively.

[0059] The disaster area division module is used to obtain aerial data corresponding to geological disaster areas, and then analyze them to obtain severe areas and mild areas.

[0060] The light area survey and analysis module is used to screen the survey equipment corresponding to each light area, and analyze the survey anomaly data set corresponding to each light area to determine whether there is a new damage form in each light area. If there is a new damage form in each light area, it will be recorded as a light target area, and the survey data corresponding to the new damage form of each light target area will be obtained to determine the damage area corresponding to each light target area.

[0061] The heavy area survey and analysis module is used to analyze the application survey equipment corresponding to each heavy area, obtain the corresponding detection data between each heavy area and the adjacent area, analyze whether tail-related damage will be formed between each heavy area and the adjacent area, and confirm the damaged area corresponding to each heavy area.

[0062] The early warning terminal is used to issue early warning prompts when new damage forms appear in a light area or when tail-related damage forms between a heavy area and the adjacent area.

[0063] The embodiment of the present invention performs a preliminary regional division of the geological disaster area, and then allocates corresponding survey equipment to different areas to conduct surveys of each mild area and each severe area. At the same time, it is judged whether there is a new damage form in each mild area and whether tail-related damage will be formed between each severe area. The damaged area corresponding to each mild target area and the damaged area corresponding to each severe area are determined, so as to clarify the damaged area corresponding to the geological disaster area, provide an effective data reference for subsequent disaster maintenance or disaster risk prediction, break the fixed thinking of only surveying the obvious damaged area during geological disaster damage survey, reduce the probability of missing detection of hidden damaged areas in geological disaster areas, reduce the damage safety hazards remaining in geological disaster areas, enable geological disaster areas to obtain a truly comprehensive summary of damaged areas, and achieve effective and accurate survey of geological disaster damaged areas.

[0064] The above content is merely an example and explanation of the concept of the present invention. Those skilled in the art may make various modifications or additions to the described specific embodiments or replace them in a similar manner. As long as they do not deviate from the concept of the invention or exceed the scope defined in this specification, they should all fall within the scope of protection of the present invention.
