[0024] The technical solution in this application is further described in detail below in conjunction with the accompanying drawings.

[0025] This application discloses a method for evaluating the damage effect of an active damage element. Figure 1 In some examples, the method for evaluating the damage effect of the active damage element disclosed in the present application includes the following steps: S101, acquiring a first image of a feature region before being damaged and a second image of a feature region after being damaged; S102, comparing the first image and the second image to determine a distinguishing area on the second image; S103, classifying the distinguished areas according to the features included in the distinguished areas, including explosion damage and impact damage; S104, counting the ratio of the distinct regions of explosion damage and the distinct regions of impact damage; S105, giving the explosive damage effect result of the active damage element according to the ratio.

[0026] The contents of step S101 to step S105 are to find the difference areas on the second image by image comparison, and then classify the difference areas into explosive damage type and impact damage type, and then count the ratio of the difference areas of the explosive damage type and the difference areas of the impact damage type to obtain a ratio value, and finally give the explosive damage effect result of the active damage element according to the ratio.

[0027] In some possible implementations, the method for finding the distinguishing areas is to divide the pixels on the image into multiple independent units, each independent unit includes multiple pixels, and then calculate the average of the pixel values ​​of the independent units, and then calculate the color difference of the independent units at corresponding positions on the first image and the second image.

[0028] After the calculation is completed, the distinguished areas are screened according to the color difference. Here, a critical value needs to be set. The area corresponding to the difference greater than the critical value is the distinguished area, such as Figure 2 shown.

[0029] For example, the number of distinguished areas is one hundred, the number of distinguished areas of explosive damage is fifty, and the number of distinguished areas of impact damage is fifty. At this time, the proportional value is one. Then, it is determined in which set range the proportional value is located. Finally, the explosive damage effect result corresponding to the set range is used as the explosive damage effect result of the proportional value.

[0030] For example, it can be stipulated that the explosive damage effect result corresponding to the proportional value greater than or equal to 2 is excellent, the explosive damage effect result corresponding to the proportional value less than or equal to 1 is unqualified, and the explosive damage effect result corresponding to the proportional value greater than 1 and less than 2 is qualified.

[0031] In some examples, after determining the distinguishing regions on the second image, the following steps are further added: Determine the length direction of the distinguishing region, and the number of the length direction is at least one; Performing integration processing on the distinguished areas on the second image according to the length direction of the distinguished areas; The differentiated regions after the integration process include at least one differentiated region that has not been integrated.

[0032] The above steps are used to integrate the distinguished areas, mainly for the distinguished areas of the explosion damage category. The distinguished areas of the explosion damage category include a main area and multiple sub-areas. These sub-areas exist around the main area or are concentrated in a certain direction of the main area. By length direction, the sub-areas belonging to the same main area can be grouped together.

[0033] After the combination is completed, a closing image is used to enclose these distinguished regions (a main region and multiple sub-regions), such as Figure 3 shown.

[0034] The specific method of integrating the difference areas on the second image according to the length direction of the difference areas is to extend them in the length direction of the difference areas. If the extension lines of several difference areas converge together, for example, they are a point or one within the allowable area, then it is considered that these difference areas are related, that is, they belong to the same explosion damage type difference area.

[0035] In some examples, the specific manner of classifying the distinguished regions according to the features included in the distinguished regions is as follows: S201, determining the center position of the distinguished area, where the center position is a point or a circular closed area; S202, create radial lines based on the center position ( Figure 4As shown in the figure, the first end of the radiation line is located at the center position, and the second end extends in a direction away from the center position, and the number of the radiation lines is multiple and evenly arranged around the center position; S203, creating an analysis reference line using the pixel points on the radiation line; S204, calculating the damage degree of the analysis reference line and using the damage degree of the analysis reference line to classify the distinguished areas.

[0036] In step S201 to step S204, the damage degree of the analysis reference line is calculated and the difference areas are classified using the damage degree of the analysis reference line. This method is to classify the difference areas according to the features included in the difference areas themselves.

[0037] The specific method for calculating the damage degree of the analysis reference line is as follows: Decomposing the analysis reference line by wavelet decomposition to obtain multiple waveforms, each of which has a frequency, an amplitude, a starting point and a cutting point; Determine the breakpoints on the analysis reference line according to the starting position point and the ending position point of the waveform; Use breakpoints to segment the analysis reference line to obtain damaged segments and non-damaged segments; Calculate the cumulative length of the damaged segment and the maximum coverage height of each damaged segment; The cumulative value of the damaged segment length and the maximum coverage height of each damaged segment is used as the damage degree of the analysis reference line.

[0038] In the above method, the segment of the waveform between two breakpoints is the damaged segment, otherwise it is the non-damaged segment, such as Figure 5 As shown, breakpoints are automatically assigned to both ends of the analysis reference line, and then the cumulative length of the damaged segment is calculated. At this time, a value less than 1 is obtained, and then the maximum coverage height of each damaged segment is calculated. The maximum coverage height here refers to the maximum amplitude of the waveform on the damaged segment.

[0039] Finally, the cumulative value of the damaged segment length and the maximum coverage height of each damaged segment is used as the damage degree of the analysis reference line.

[0040] Based on the above statements, it can be seen that the damage method of the active damage element mentioned in this application is multi-point damage within a large range, and there is a certain distance between adjacent active damage elements, which mainly achieves a large-scale coverage of the target.

[0041] For the impact damage distinction area, the damage types involved are impact deformation and impact damage. For the explosion damage distinction area, the damage type involved is explosion damage. A major difference between explosion damage and impact deformation and impact damage is the range.

[0042] When calculating the cumulative value of the damaged section length and the maximum coverage height of each damaged section after integrating the different areas, the cumulative value of the damaged section length and the maximum coverage height of each damaged section calculated for the different areas corresponding to the explosion damage is significantly greater than the cumulative value of the damaged section length and the maximum coverage height of each damaged section calculated for the different areas corresponding to the impact deformation and impact damage.

[0043] A damage degree reference value will be set here, and the calculated damage degree will be compared with the damage degree reference value. The analysis reference line will be classified according to the comparison result. The area corresponding to the analysis reference line with a damage degree less than the damage degree reference value is the impact damage type distinction area, otherwise it is the explosion damage type distinction area.

[0044] When the number of analysis reference lines is one, the above-mentioned method is used for processing. When the number of analysis reference lines is multiple, a statistical method is used for processing. For example, if the result that the area corresponding to the analysis reference line is a burst damage distinction area exceeds the set ratio, then the distinction area is determined to be a burst damage distinction area, otherwise it is an impact damage distinction area.

[0045] In some possible implementations, after decomposing the analysis reference line using wavelet decomposition, waveforms with amplitudes less than or equal to a set amplitude are deleted. Here, waveforms with amplitudes less than or equal to a set amplitude are considered to be interferences, which will affect the division of damaged segments and non-damaged segments.

[0046] The present application also provides a method for dividing the damaged segment and the non-damaged segment, which is as follows: Determine the stability of the analysis reference line corresponding to each segment; The distinguished areas are classified according to the stability, and the segments with a stability less than a first set threshold are recorded as non-damaged segments, and the segments with a stability greater than the first set threshold are recorded as damaged segments.

[0047] This method can achieve further accurate division of damaged segments and non-damaged segments. The specific method is to divide them according to the stability of the analysis reference line corresponding to the segment. Stability means that the amplitude of the waveform obtained by analyzing the analysis reference line corresponding to each segment fluctuates within the allowable range. The difference between the maximum and minimum values ​​of the allowable range is the stability. In other words, stability is a specific value.

[0048] The present application also provides a damage effect evaluation device for an active damage element, comprising: An image acquisition unit, used to acquire a first image of the characteristic region before being damaged and a second image of the characteristic region after being damaged; An image comparison unit, used for comparing the first image with the second image, and determining a difference area on the second image; A classification processing unit, used for classifying the distinguished areas according to the features included in the distinguished areas, including explosion damage and impact damage; A statistical processing unit, used to count the ratio of the distinguished areas of explosion damage and the distinguished areas of impact damage; The result output unit is used to give the explosion damage effect result of the active damage element according to the ratio.

[0049] Furthermore, after determining the distinguishing area on the second image, the method further includes: Determine the length direction of the distinguishing region, and the number of the length direction is at least one; Performing integration processing on the distinguished areas on the second image according to the length direction of the distinguished areas; The differentiated regions after the integration process include at least one differentiated region that has not been integrated.

[0050] Further, classifying the distinguishing regions according to the features included in the distinguishing regions includes: Determine the center position of the distinguished area, which is a point or a circular closed area; Creating radial lines based on the central position, wherein a first end of the radial line is located at the central position, and a second end of the radial line extends in a direction away from the central position, and the number of the radial lines is multiple and is evenly arranged around the central position; Use the pixels on the radial lines to create analysis reference lines; The damage degree of the analysis reference line is calculated and the difference area is classified using the damage degree of the analysis reference line.

[0051] Furthermore, the damage degree of the analysis reference line is calculated including: Decomposing the analysis reference line by wavelet decomposition to obtain multiple waveforms, each of which has a frequency, an amplitude, a starting point and a cutting point; Determine the breakpoints on the analysis reference line according to the starting position point and the ending position point of the waveform; Use breakpoints to segment the analysis reference line to obtain damaged segments and non-damaged segments; Calculate the cumulative length of the damaged segment and the maximum coverage height of each damaged segment; The cumulative value of the damaged segment length and the maximum coverage height of each damaged segment is used as the damage degree of the analysis reference line.

[0052] Furthermore, after the analysis reference line is decomposed by wavelet decomposition, the waveforms with amplitudes less than or equal to the set amplitude are deleted.

[0053] Furthermore, using breakpoints to segment the analysis reference line and obtain damaged segments and non-damaged segments includes: Determine the stability of the analysis reference line corresponding to each segment; Classify the difference regions according to the stability. The segments with stability less than the first set threshold are recorded as non-damaged segments, and the segments with stability greater than the first set threshold are recorded as damaged segments.
