[0020] Additionally, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, one skilled in the art will appreciate that aspects may be practiced without these specific details.
[0021] refer to Figure 1 The present application provides a method for identifying a dry-burned cooker, comprising the following steps: S101, acquiring infrared image data of a to-be-monitored area, wherein the to-be-monitored area includes a pot in a heating state.
[0022] In this embodiment, an infrared image of the area to be monitored is captured by an infrared camera device, and the infrared image is converted into infrared image data including pixel values of multiple pixel points. The infrared camera device in this implementation may be an infrared detector or other device that can be used to obtain infrared data, and this embodiment does not limit the specific type or model of the infrared camera device. In an optional embodiment, the infrared camera device may use the Heiman sensor HTPA32x32dR2L2.1. The Heiman sensor has a high-performance, high-quality digital signal thermopile infrared array with 32x32 pixels in a TO-39 metal housing. Using an integrated optical lens, the field of view can be adjusted from 33° to 105°.
[0023] It should be noted that when setting up the infrared camera equipment, it should be ensured that the pot is within the photographic range of the infrared camera equipment to ensure that the infrared camera equipment can accurately capture the infrared image data of the pot in the heated state.
[0024] S102, identifying the pot eye position of the cookware according to the pixel value of the infrared image data.
[0025] In this embodiment, after the pixel values of the infrared image data are obtained, the position of the pot eye of the pot can be identified through the correspondence between the pixel values of different pixel points. In actual application, when the pot is in a heating state, for example, when it is placed on a stove and heated with an open flame, the flame will be randomly distributed around the pot due to the size of the pot body. By identifying the position of the pot eye of the pot and monitoring the temperature of the pot eye position, the recognition error caused by the random distribution of the flame can be greatly avoided.
[0026] S103, monitoring the temperature value at the pot eye position.
[0027] In this embodiment, the temperature value of the corresponding pixel point can be directly obtained based on the infrared image data collected by the infrared detector through the corresponding relationship between the infrared image data and the temperature value, and the temperature value of the corresponding pixel point can also be collected through other temperature detector devices. The conversion relationship between the pixel value and the temperature value in the infrared image data can be adaptively configured according to the needs of the actual application scenario, which is not limited here.
[0028] By accurately identifying the position of the pot eye of the cooker through infrared image data and then monitoring the temperature value at the pot eye position in real time, it is possible to promptly and accurately identify whether the cooker is in a dry-burning state and take timely measures to prevent the cooker from dry-burning.
[0029] It should be noted that the pot dry-boiling prevention process includes but is not limited to alarming through a buzzer, sending an alarm signal to a user terminal, and controlling the heating device to shut down, etc. This embodiment does not limit the subsequent solution of the pot dry-boiling prevention process, and can be adaptively configured according to the needs of actual application scenarios.
[0030] S104: If the temperature value at the pot eye position is greater than or equal to the temperature threshold, it is determined that the pot is in a dry-burning state.
[0031] In this embodiment, the temperature threshold can be set to 70°C, or 68-75°C, or adaptively configured according to the needs of the actual application scenario. In a specific embodiment, when the temperature at the pot eye is 70°C, heating continues for 40 seconds, and the temperature value at the pot eye exceeds 89 degrees Celsius, which may cause the pot to overheat and be damaged.
[0032] This embodiment monitors the temperature value at the pot eye position, and determines that the pot is in a dry-burning state when the temperature value at the pot eye position is greater than or equal to a temperature threshold.
[0033] It should be noted that in a feasible embodiment, the temperature rising rate at the pot eye position can also be monitored. When the rising rate of the temperature at the pot eye position within a certain time range is greater than a rate threshold, it is determined that the pot is in a dry burning state.
[0034] In summary, this embodiment provides a method for identifying dry-burning cookware. By setting up a simple infrared detector device and combining it with unique logical judgment, it can accurately and quickly identify whether the cookware is in a dry-burning state. The method for identifying dry-burning cookware proposed in this embodiment can effectively avoid interference from environmental factors and will not affect the dry-burning identification results due to light or dust.
[0035] According to a specific implementation of the embodiment of the present application, Figure 2 As shown, the pot eye position of the pot is identified according to the pixel value of the infrared image data, including: S202, performing sliding filtering on the infrared image data according to a filter matrix of a preset ratio to obtain filtered image data.
[0036] In this embodiment, the infrared image data may be subjected to sliding filtering based on a 3*3 filter matrix to obtain filtered image data. Specifically, the image data before and after sliding filtering may be as follows: Figure 3 The preset ratio of the filter matrix can be adaptively replaced according to the needs of the actual application scenario, for example, replaced with 5*5, 4*4, etc.
[0037] In a specific embodiment, the sliding filtering method in this embodiment adopts sliding mean filtering to ensure that the subsequent first pixel judgment rule and the second pixel judgment rule can accurately identify the pot eye position of the pot. It should be noted that the specific filtering method of the sliding filtering method can be adaptively replaced according to the needs of the actual application scenario.
[0038] In actual application, Figure 3 As shown, the edge parts of the filtered image data, namely the first row, first column, last row and last column, can keep the pixel values of the infrared image data unchanged, while the pixel values of the pixels in other areas need to be processed by mean filtering with a preset ratio of the filter matrix.
[0039] S203, obtaining a region to be identified in the filtered image data according to the specification of a preset judgment matrix.
[0040] In this embodiment, the preset judgment matrix can be used as follows: Figure 5 The specific specifications of the preset judgment matrix can also be adaptively replaced according to the needs of the actual application scenario.
[0041] After determining the preset judgment matrix, it is necessary to determine a region to be identified from the filtered image data to ensure that each pixel in the region can be identified based on the preset judgment matrix to determine whether it belongs to the pot eye position. Figure 5 The matrix type shown is used to filter the image data. Figure 3 In the screenshot data shown, the area to be identified is the area from column 5 to column 28 and row 3 to row 29. It should be noted that the specific range of the area to be identified can be determined according to the needs of the actual application scenario.
[0042] S204: Filter out a target area from the area to be identified according to the first pixel judgment rule, wherein the size of the target area is equal to the size of a preset judgment matrix.
[0043] In this embodiment, the first pixel judgment rule is used to judge the range of the area where the pot eye position may exist, that is, the range of the target area. The target areas screened out based on the first judgment rule may be multiple or a single one.
[0044] In this embodiment, only after the target area is screened out from the area to be identified according to the first pixel determination rule, is it identified whether the target area includes the pot eye of the cookware according to the second pixel determination rule.
[0045] The size of the target area is the same as the size of the preset judgment matrix. Figure 5 As shown, the target area is the same as the preset judgment matrix, both of which are 5*5 matrices.
[0046] S205: Identify the pot eye position of the cookware from the target area according to the second pixel judgment rule.
[0047] In this embodiment, the second pixel judgment rule can accurately identify the position of the pot eye of the cookware, that is, when the conditions set by the second pixel judgment rule are met, the center point of the preset judgment matrix (target area) is the position of the pot eye of the cookware.
[0048] According to a specific implementation of the embodiment of the present application, Figure 4 As shown, the target area is screened out from the area to be identified according to the first pixel judgment rule, including: S401, obtaining a first pixel value and a second pixel value in a preset judgment matrix, wherein the first pixel value is a pixel value of a center point, and the second pixel value is a pixel value of a pixel point adjacent to the center point; S402: When at least six second pixel values are greater than the first pixel value, determine the area where the preset judgment matrix is located as the target area.
[0049] In this embodiment, if Figure 5 As shown, the first pixel value refers to the pixel value of the pixel point where pixel_5 is located. The second pixel value refers to the pixel values of the pixel points where pixel_1, pixel_2, pixel_3, pixel_4, pixel_6, pixel_7, pixel_8, and pixel_9 are located.
[0050] If and only if there are at least 6 second pixel values that are all greater than the first pixel value, the area where the preset judgment matrix is located is determined as the target area to execute the second pixel judgment rule.
[0051] In a preferred embodiment, when all second pixel values are required to be greater than the first pixel value, the area where the preset judgment matrix is located is determined as the target area to ensure recognition accuracy.
[0052] According to a specific implementation of the embodiment of the present application, Figure 6 As shown, identifying the pot eye position of the pot from the target area according to the second pixel judgment rule includes: S601, obtaining a first pixel value, a third pixel value, and a fourth pixel value in a preset judgment matrix, wherein the first pixel value is a pixel value of a center point, the third pixel value is a pixel value of a pixel point adjacent to the center point, and the fourth pixel value is a pixel value that is vertically or horizontally spaced one pixel from the center point; S602: When the third pixel value in any direction is smaller than the first pixel value and the fourth pixel value in the same direction is larger than the first pixel value, the pixel point corresponding to the first pixel value is determined as the pot eye position of the cookware.
[0053] In this embodiment, if Figure 5 As shown, the first pixel value refers to the pixel value of the pixel point where pixel_5 is located. The third pixel value refers to the pixel value of the pixel points where pixel_2, pixel_4, pixel_6, and pixel_8 are located. The fourth pixel value refers to the pixel value of the pixel points where pixel_10, pixel_11, pixel_12, and pixel_13 are located.
[0054] During the judgment process, if any one of the following conditions is met, the pot eye position of the central pixel point is determined: pixel_5>pixel_2, and pixel_5<pixel_10; pixel_5>pixel_4, and pixel_5<pixel_11; pixel_5>pixel_6, and pixel_5<pixel_12; pixel_5>pixel_8, and pixel_5<pixel_13.
[0055] It should be noted that if the above conditions are not met, it is determined that the target area does not include the pot eye position, and other target areas are identified based on the second pixel judgment rule until the pot eye position of the pot is identified.
[0056] According to a specific implementation of the embodiment of the present application, the method for identifying a dry-burned cooker further includes: If the pot eye position is not identified based on the current infrared image data: Control the infrared detector to adjust the shooting angle and reacquire the infrared image data of the area to be monitored until the pot eye position is identified.
[0057] In this embodiment, if the pot eye position is not included in all the target areas filtered out by the current infrared image data, it can be determined that the pot eye position of the pot cannot be photographed within the shooting angle of the infrared detector, or the infrared detector is abnormal. At this time, the infrared detector is controlled to automatically adjust the shooting angle to ensure that the pot in the heating state is within the shooting range of the infrared detector, and the infrared image data acquisition step and the pot eye position recognition step in the above method embodiment are re-executed.
[0058] In this embodiment, if the infrared detector adjusts the shooting angle multiple times and still cannot identify the position of the pot eye, an abnormal prompt message is sent to the user terminal to prompt the user to check the status and setting position of the infrared detector to repair the abnormality and ensure that it can detect in time whether the pot is in a dry-burning state.
[0059] To sum up, the present embodiment provides a method for identifying dry-burning cookware, which can accurately, quickly and effectively identify whether the cookware is in a dry-burning state, and promptly alarm the user to prevent the cookware from being damaged due to overheating caused by dry-burning. At the same time, the execution logic of the method for identifying dry-burning cookware in the present embodiment is simple. While not occupying too many computing resources, it can also effectively avoid interference from environmental factors, thereby further improving the accuracy of dry-burning state identification.
