Abstract
Description
Technical Field
[0001] This application relates to the field of image recognition technology, and in particular to a method for identifying combustible substances, an electronic device, and a readable storage medium. Background Technology
[0002] Fire has become a frequent disaster endangering people's lives and property. In a fire, smoke and flames are the first and most important identifiable signals of its occurrence. By analyzing smoke and flames, it is possible to effectively help relevant rescue personnel respond to fires in a timely manner and minimize casualties and property losses. Currently, many video surveillance devices used in production and daily life have fire smoke detection functions, which can quickly identify the occurrence of fires. However, different fires require different rescue methods. After arriving at the scene, firefighters need to formulate a rescue plan based on the actual situation visible outside the fire scene and select appropriate fire extinguishers. Common fire extinguishers are roughly divided into dry powder fire extinguishers, halon fire extinguishers, carbon dioxide fire extinguishers, foam fire extinguishers, etc., and their uses are different. The accuracy of the rescue plan has a significant impact on the effectiveness of fire rescue. Summary of the Invention

The measured smoke color for each target smoke region is determined based on its measured smoke pixel values, and the measured flame color for each target flame region is determined based on its measured flame pixel values. This achieves the determination of corresponding smoke and flame colors based on image pixels of the smoke and flame regions, and identification based on the measured smoke and flame colors. The target combustion material identification system enables the recognition and judgment of combustion materials based on the different colors of smoke and flames produced by the combustion of different substances. It only requires acquiring images of the fire scene during the fire's occurrence, and can quickly determine the combustion materials in the fire by detecting the colors of smoke and flames in the images. This provides effective and accurate technical support for the formulation of rescue plans, allowing rescuers to determine accurate rescue plans as early as possible before arriving at the scene. This avoids the situation where rescuers can only formulate less accurate rescue plans based on the external visible scene of the fire without knowing the internal combustion materials, thus overcoming the technical problem of low accuracy in fire rescue plans and greatly improving the effectiveness of fire rescue.

[0045] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0046] Fire has become a frequent disaster threatening people's lives and property. In a fire, smoke and flames are the first and most important identifiable signals. Analyzing smoke and flames can effectively help rescue personnel respond to fires promptly, minimizing casualties and property damage. Currently, many video surveillance devices used in production and daily life have fire smoke detection functions, enabling them to quickly identify fires. However, different fires require different rescue methods. Upon arrival at the scene, firefighters need to formulate a rescue plan based on the visible external conditions of the fire and select appropriate fire extinguishers. Common fire extinguishers are broadly classified into dry powder extinguishers, halon extinguishers, carbon dioxide extinguishers, and foam extinguishers, each with different uses, such as: Dry powder fire extinguishers can be used to extinguish flammable liquids, flammable gases, and electrical equipment, but cannot be used to extinguish fires involving reactive metals. Halon fire extinguishers can be used to extinguish fires involving oils and electrical equipment, but cannot be used to extinguish fires involving reactive metals or metal hydrides. Carbon dioxide fire extinguishers can be used to extinguish flammable liquids and flammable gases, but cannot be used to extinguish fires involving metal hydrides or inside fibrous materials. Foam fire extinguishers are generally used to extinguish flammable liquid fires, but cannot be used to extinguish water-soluble liquids or light metal fires. Therefore, simply knowing whether a fire has occurred is insufficient for fire safety work; it is necessary to further determine the type of fire to provide guidance for subsequent fire rescue work. The accuracy of the rescue plan has a significant impact on the effectiveness of fire rescue. If the burning material can be identified in advance, it can greatly facilitate the fire rescue operation.
[0047] This application provides a method for identifying combustible substances. In the first embodiment of this method, refer to... Figure 1 The method for identifying combustible substances includes:
[0048] Step S10: Obtain images of the fire scene;
[0049] In this embodiment, specifically, when the fire detection device detects a fire, it acquires image data of the fire scene and obtains one or more fire scene pictures from the fire scene image data. The fire scene image data includes monitoring videos of the fire scene, video data taken by on-site personnel, and / or photos taken on-site. The fire scene pictures include on-site pictures at different stages of the fire, for example, pictures taken from different times during the process of the fire starting to intensify, obtained from images taken from monitoring videos.
[0050] Step S20: Extract at least one target smoke area and at least one target flame area from the fire scene image;
[0051] In this embodiment, specifically, smoke and flame images are identified from the fire scene images using image recognition technology, and target smoke regions containing all or part of the smoke images and target flame regions containing all or part of the flame images are extracted. The target smoke region can be a square region, a circular region, an irregular region, or a region encompassed by the outer contour of the identified smoke image, etc. The target flame region can be a square region, a circular region, an irregular region, or a region encompassed by the outer contour of the identified flame image, etc. In one implementable method, referring to... Figure 3 ,exist Figure 3 In the image, regions A, B, C, D, and E are the target smoke and target flame regions extracted from a fire scene image using image recognition technology. Regions A, B, C, and D are the target smoke regions, and region E is the target flame region.
[0052] Step S30: Determine the measured smoke color corresponding to each of the target smoke regions based on the measured smoke pixel values of each target smoke region, and determine the measured flame color corresponding to each of the target flame regions based on the measured flame pixel values of each target flame region.
[0053] In this embodiment, specifically, at least one measured smoke pixel value and at least one measured flame pixel value for each of the target smoke regions are collected. The smoke pixel value range to which all or part of the measured smoke pixel values of each target smoke region belong is determined. Based on a preset mapping relationship between pixel value ranges and colors, the color corresponding to each of the measured smoke pixel values of each target smoke region is determined. Colors exceeding a preset number or proportion are determined as the measured smoke color corresponding to each target smoke region. Similarly, the flame pixel value range to which all or part of the measured flame pixel values of each target flame region belong is determined. Based on a preset mapping relationship between pixel value ranges and colors, the color corresponding to each of the measured flame pixel values of each target flame region is determined. Colors exceeding a preset number or proportion are determined as the measured flame color corresponding to each target flame region. In this embodiment, each pixel of an image is composed of three channels: red, green, and blue. Therefore, the pixel value is composed of three values: R (red), G (green), and B (blue). The mapping relationship between the pixel value range and the color can be determined based on existing research results, big data, or custom settings. For example, a pixel value with an R value greater than or equal to 195, a G value greater than or equal to 195, and a B value greater than or equal to 195 can be defined as white. A pixel value with an R value greater than 122 and less than 180, a G value greater than 122 and less than 180, and a B value greater than 122 and less than 180 can be defined as gray. In one feasible approach, before extracting the measured smoke pixel value and the measured flame pixel value, image processing such as background removal, light adjustment, and tone adjustment can be performed on the image to reduce the influence of environmental factors or hardware devices such as cameras on the smoke and flame images.
[0054] Optionally, the step of determining the measured smoke color corresponding to each of the target smoke regions based on the measured smoke pixel values of each target smoke region includes:
[0055] Step A10: Determine the range of smoke pixel values to which each measured smoke pixel value belongs in each of the target smoke regions;
[0056] In this embodiment, it should be noted that the range of smoke pixel values is a range of pixel values that is determined in advance based on the color of the smoke produced when various types of combustible substances are burned.
[0057] Specifically, the range of smoke pixel values to which each measured smoke pixel value belongs in each target smoke region is determined.
[0058] Step A20: If, among the measured smoke pixel values corresponding to each of the target smoke regions, there are more than a preset first proportion of measured smoke pixel values belonging to the same smoke pixel value range, then the same smoke pixel value range is taken as the target smoke pixel value range.
[0059] In this embodiment, specifically, if in any target smoke area, the proportion of measured smoke pixel values belonging to a certain same smoke pixel value range in the total measured smoke pixel values in the target smoke area exceeds a preset first proportion, then the same smoke pixel value range is taken as the target smoke pixel value range.
[0060] Step A30: Determine the smoke color corresponding to the target smoke pixel value range as the measured smoke color corresponding to the target smoke region.
[0061] In this embodiment, specifically, the target smoke color corresponding to the target smoke pixel value is determined according to the preset mapping relationship between smoke pixel value and smoke color, and the target smoke color is determined as the measured smoke color corresponding to the target smoke region. It is easy to understand that when there is more than one target smoke region, each target smoke region has a corresponding measured smoke color, and the measured smoke colors of different target smoke regions can be the same or different.
[0062] Optionally, the step of determining the measured flame color corresponding to each of the target flame regions based on the measured flame pixel values of each target flame region includes:
[0063] Step B10: Determine the range of flame pixel values to which each measured flame pixel value belongs in each of the target flame regions;
[0064] In this embodiment, it should be noted that the range of flame pixel values is a range of pixel values that is determined in advance based on the color of the flame produced when various types of combustible substances are burned.
[0065] Specifically, the range of flame pixel values to which each measured flame pixel value belongs in each target flame region is determined.
[0066] Step B20: If, among the measured flame pixel values corresponding to each of the target flame regions, there are more than a preset second proportion of measured flame pixel values belonging to the same flame pixel value range, then the same flame pixel value range is taken as the target smoke pixel value range.
[0067] In this embodiment, specifically, if in any target flame region, the proportion of measured flame pixel values belonging to a certain same flame pixel value range in all measured flame pixel values in the target flame region exceeds a preset first proportion, then the same flame pixel value range is taken as the target flame pixel value range.
[0068] Step B30: Determine the flame color corresponding to the target flame pixel value range as the measured flame color corresponding to the target flame region.
[0069] In this embodiment, specifically, the target flame color corresponding to the target flame pixel value is determined according to the preset mapping relationship between flame pixel value and flame color, and the target flame color is determined as the measured flame color corresponding to the target flame region. It is easy to understand that when there is more than one target flame region, each target flame region has a corresponding measured flame color, and the measured flame colors of different target flame regions can be the same or different.
[0070] Step S40: Identify the target burning substance based on the measured smoke color and the measured flame color.
[0071] In this embodiment, it should be noted that the target combustible material is the combustible material at the fire scene. It can be a specific substance, such as magnesium or diesel, or it can be a general term for a class of substances, such as combustible gas, combustible metal, or electrical equipment. It can also include both specific substances and a general term for a class of substances. The specific terms can be set according to the actual situation.
[0072] Specifically, based on a preset mapping table of smoke color and combustible material, one or more first initial combustible materials corresponding to each measured smoke color can be determined. Similarly, based on a preset mapping table of flame color and combustible material, one or more second initial combustible materials corresponding to each measured flame color can be determined. Combustible materials that are repeated in each first and second initial combustible material are identified as the target combustible material corresponding to the fire scene image. It is easy to understand that different target smoke areas can correspond to the same or different measured smoke colors, and different target flame areas can also correspond to the same or different measured flame colors. Alternatively, based on the combination of smoke color and flame color, a preset mapping table of combinations and combustible materials can be consulted to determine the combustible material corresponding to the combination. For example, refer to... Figure 3 If the measured smoke color of target smoke area A is determined to be gray, the measured smoke color of target smoke area B is black, the measured smoke color of target smoke area C is black, the measured smoke color of target smoke area D is gray, and the measured flame color of target flame area E is red, then the measured smoke colors include black and gray, and the measured flame colors include red. We can first determine that the combustible substances corresponding to black smoke include a and b, the combustible substances corresponding to gray smoke include b, c, and d, and the combustible substances corresponding to red flames include c and d. Finally, we can determine that the target combustible substances are c and d. Alternatively, we can first determine that the combinations of smoke and flame colors include combinations of black smoke and red flames, as well as combinations of gray smoke and red flames. Then, we can determine that the combination of black smoke and red flames has no corresponding combustible substances, and the combination of gray smoke and red flames corresponds to combustible substances c and d. Finally, we can determine that the target combustible substances are c and d.
[0073] Optionally, the step of identifying the target combustible material based on the measured smoke color and the measured flame color includes:
[0074] Based on the mapping relationship between the combination of smoke color and flame color and the burning substance, the target burning substance corresponding to the actual combination of the measured smoke color and the measured flame color is determined.
[0075] In this embodiment, specifically, the determined measured smoke colors and measured flame colors are combined to obtain an actual combination composed of the measured smoke colors and measured flame colors. Based on the pre-established mapping relationship between the combination of smoke colors and flame colors and the combustion substances, the target combustion substance corresponding to the actual combination is determined.
[0076] Optionally, after the step of identifying the target combustible material based on the measured smoke color and the measured flame color, the method further includes:
[0077] Step S50: Output identification result information and prompts for viewing image data based on the target combustible material.
[0078] In this embodiment, specifically, the target combustible material is output as a combustible material identification result to inform relevant personnel of the combustible material at the fire scene. This allows relevant personnel to select appropriate fire extinguishers and formulate suitable rescue plans based on the combustible material at the fire scene. A prompt message is also output to allow relevant personnel to determine whether to view the image data of the fire scene, further confirming the situation at the fire scene, the location of the combustible material, and other detailed information. The image data can be a picture of the fire scene, a video of the fire scene, or a processed image of the fire scene, such as a fire scene picture marked with target smoke and target flame areas, or a fire scene picture with adjusted color or lighting.
[0079] In this embodiment, by acquiring images of the fire scene, at least one target smoke region and at least one target flame region are extracted from the images, achieving feature extraction of smoke and flame from the fire scene images. The measured smoke color of each target smoke region is determined based on the measured smoke pixel values, and the measured flame color of each target flame region is determined based on the measured flame pixel values, achieving the determination of corresponding smoke and flame colors based on image pixels of the smoke and flame regions. By identifying the target burning material based on the measured smoke and flame colors, the system achieves root... Based on the different colors of smoke and flames produced by the combustion of different substances, the burning materials can be identified and judged. Only images of the fire scene during the fire process are needed; by detecting the colors of smoke and flames in the images, the burning materials in the fire can be quickly determined. This provides effective and accurate technical support for the formulation of rescue plans, allowing rescuers to determine an accurate rescue plan as early as possible before arriving at the scene. This avoids the situation where rescuers can only formulate less accurate rescue plans based on the external visible scene of the fire without knowing the internal burning materials. Therefore, it overcomes the technical problem of low accuracy in fire rescue plans and greatly improves the effectiveness of fire rescue.
[0080] Furthermore, referring to Figure 2 In another embodiment of this application, content that is the same as or similar to the above embodiment can be referred to the above description, and will not be repeated hereafter. Based on this, the step of obtaining at least one target function file according to the personalized configuration information includes:
[0081] Step S51: When an image data viewing request triggered by the prompt information is detected, the target smoke areas and the target flame areas are standardized to obtain a standard fire scene image.
[0082] In this embodiment, it should be noted that due to differences in time, light source, shooting equipment, and other conditions, the same color may appear differently in images taken by different shooting equipment in different environments. Standardization processing is the process of replacing pixels in the target smoke area that are similar to a certain preset reference color with that preset reference color.
[0083] Specifically, when a user operation triggered by the prompt information is detected to view image data, each pixel value of each target smoke area and each target flame area in the fire scene image is matched with a preset reference pixel value. The pixel values in the target smoke area and each target flame area that can match the reference pixel value are replaced with the corresponding reference pixel values to obtain a standard fire scene image.
[0084] Optionally, the step of standardizing each of the target smoke areas and each of the target flame areas to obtain a standard fire scene image when an image viewing request triggered based on the prompt information is detected includes:
[0085] Step C10: When an image data viewing request triggered by the prompt information is detected, the target smoke areas and the target flame areas are standardized to obtain a standard target image;
[0086] In this embodiment, specifically, when a user operation triggered by the prompt information is detected to view image data, each pixel value of each target smoke area and each target flame area in the fire scene image is matched with a preset reference pixel value. The pixel values in the target smoke area and each target flame area that can match the reference pixel value are replaced with the corresponding reference pixel values to obtain a standard target image.
[0087] Step C20: Obtain the fire video corresponding to the fire scene image and related images in the fire video that are adjacent to the fire scene image at a preset number of frames;
[0088] In this embodiment, specifically, the fire video corresponding to the fire scene image is obtained, the arrangement position of the fire scene image in the fire video is determined, and related images of a preset number of frames in the fire video adjacent to the arrangement position of the fire scene image are obtained. The arrangement position can be determined according to frame order, number, etc. For example, z-frame images in the fire video arranged before and / or after the fire scene image are taken as related images.
[0089] Step C30: Extract at least one relevant smoke region and at least one relevant flame region from the relevant images, and standardize each of the relevant smoke regions and each of the relevant flame regions to obtain a standard relevant image;
[0090] In this embodiment, specifically, at least one related smoke region and at least one related flame region are extracted from the related image using image recognition technology. Each pixel value of each related smoke region and each related flame region in the related image is matched with a preset reference pixel value. The pixel values in the related smoke region and each related flame region that can match the reference pixel value are replaced with the corresponding reference pixel value to obtain a standard related image.
[0091] Step C40: Combine the standard target image and the standard related image to generate a dynamic standard fire scene image.
[0092] In this embodiment, specifically, the standard target image and the standard related image are combined according to their arrangement order in the video to generate a dynamic standard fire scene image.
[0093] Optionally, the step of standardizing each of the target smoke regions and each of the target flame regions includes:
[0094] Step D10: Determine whether the measured smoke pixel values of each of the target smoke regions belong to the first threshold range of the preset reference smoke pixel values;
[0095] Step D20: Replace the initial smoke pixel value that belongs to the first threshold interval in each of the measured smoke pixel values with the reference smoke pixel value;
[0096] In this embodiment, it should be noted that the reference smoke pixel value is the pixel value corresponding to the standard color of smoke and flame produced when the combustible substance is burned. The standard color can be obtained by testing with a set standard environment and shooting equipment, or it can be obtained from papers or big data analysis. This embodiment does not limit this. The threshold is an error range determined according to the actual situation. It can be obtained by testing with a set standard environment and shooting equipment, or it can be obtained from papers or big data analysis. This embodiment does not limit this. For example, if the reference smoke pixel value is R value 50, G value 50, B value 50, and the threshold is 15, then pixel values with R value between 35-65, G value between 35-65, and B value between 35-65 are within the threshold.
[0097] Specifically, it is determined whether each measured smoke pixel value in each target smoke region belongs to a preset threshold value of a baseline smoke pixel value. The initial smoke pixel value in each measured smoke pixel value that belongs to the first threshold interval is replaced with the baseline smoke pixel value, and the initial smoke pixel value in each measured smoke pixel value that belongs to the first threshold interval is kept unchanged.
[0098] Step D30: Determine whether the measured flame pixel value of each of the target flame regions belongs to the second threshold range of the preset reference flame pixel value;
[0099] Step D40: Replace the initial flame pixel value that belongs to the second threshold interval among the measured flame pixel values with the reference flame pixel value.
[0100] In this embodiment, it should be noted that the reference flame pixel value is based on the pixel value corresponding to the flame and standard color of the flame produced when the combustible material is burned. The standard color can be obtained by testing with a set standard environment and shooting equipment, or by obtaining it from papers or big data analysis. This embodiment does not limit this. The threshold is an error range determined according to the actual situation. It can be obtained by testing with a set standard environment and shooting equipment, or by obtaining it from papers or big data analysis. This embodiment does not limit this. For example, if the reference flame pixel value is R value 50, G value 50, B value 50, and the threshold is 15, then pixel values with R value between 35-65, G value between 35-65, and B value between 35-65 are within the threshold.
[0101] Specifically, it is determined whether each measured flame pixel value of each target flame region belongs to a preset threshold value of a reference flame pixel value. The initial flame pixel value belonging to the first threshold interval in each measured flame pixel value is replaced with the reference flame pixel value, and the initial flame pixel value belonging to the first threshold interval in each measured flame pixel value is kept unchanged.
[0102] Step S52: Display the standard fire scene image.
[0103] In this embodiment, specifically, the standard fire scene images are displayed so that users can more intuitively view more standard and clearer images of smoke and flames, thereby more accurately judging the burning material and the situation of the fire scene. In one feasible approach, the display of the standard fire scene images can also be achieved by establishing a link between the standard fire scene images and the identified burning material. Based on the user's selection of the target burning material, the fire scene images corresponding to the user's selected target burning material are displayed. When multiple fire scene images exist, different burning materials may be ignited at different stages of the fire, so different fire scene images may identify different burning materials. When a user selects different burning materials, they want to understand the specific situation of that burning material. Therefore, displaying the fire scene images corresponding to the burning material makes it easier for users to directly obtain the required fire scene images and understand accurate fire information in a timely manner.
[0104] Furthermore, embodiments of the present invention provide an electronic device, the electronic device comprising: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, the instructions being executed by the at least one processor to enable the at least one processor to perform the combustible substance identification method of Embodiment 1 described above.
