[0057] Currently, with the rapid development of air conditioner technology, the number of air conditioners installed in various indoor spaces is increasing. More and more users are choosing to install air conditioners for temperature control in high-temperature indoor areas such as kitchens. Existing air conditioners can detect users and execute corresponding control operations. However, in scenarios such as kitchens, the background environment is complex and subject to significant changes, which can lead to ineffective recognition of user image information, resulting in inaccurate air conditioner control and an inability to meet current air conditioning control needs.

[0058] Based on this, this application proposes an air conditioning control method, apparatus, device, and computer-readable storage medium to solve the technical problem in the prior art that the user's image information cannot be accurately identified in complex or highly variable backgrounds, leading to abnormal air conditioning control.

[0059] The air conditioning control method in this embodiment of the invention is applied to an air conditioning control device, which is set in an air conditioning control equipment. The air conditioning control equipment is provided with one or more processors, a memory, and one or more application programs, wherein the one or more application programs are stored in the memory and configured to be executed by the processor to implement the air conditioning control method. The air conditioning control equipment can be a smart terminal, such as a mobile phone, tablet computer, network device, and smart computer. Optionally, the air conditioning control equipment can also be a server or a service cluster composed of multiple servers.

[0060] like Figure 1 As shown, Figure 1 This is a schematic diagram of a scenario illustrating the air conditioning control method according to an embodiment of this application. The air conditioning control scenario in this embodiment includes an air conditioning control device 100 (which integrates an air conditioning control unit) and an air conditioner 200. The air conditioning control device 100 has a computer-readable storage medium running on it, corresponding to the air conditioning control method, to execute the steps of the air conditioning control method. The air conditioner 200 is an intelligent air conditioner that communicates with the air conditioning control device 100 and is capable of responding to the control interaction of the air conditioning control device. Optionally, in a specific embodiment, the air conditioning control device may also be an air conditioning main control module inside the air conditioner.

[0061] Understandable, Figure 1 The air conditioning control device in the air conditioning control method scenario shown, or the device included in the air conditioning control device, does not constitute a limitation on the embodiments of the present invention. That is, the number or type of air conditioning control device included in the air conditioning control method scenario, or the number or type of device included in each device, does not affect the overall implementation of the technical solution in the embodiments of the present invention, and can all be considered as equivalent substitutions or derivatives of the technical solutions claimed in the embodiments of the present invention.

[0062] In this embodiment of the invention, the air conditioning control device 100 is mainly used for: responding to an air conditioning control request and acquiring a scene image sequence corresponding to the air conditioning operating area; performing mode background modeling on the scene image sequence based on the pixel grayscale values ​​of the scene image sequence to obtain an initial reference background for the scene image sequence; obtaining a local scene operator for a target image block based on the initial reference background and block smoothing processing in the scene image sequence, and determining the target scene background of the scene image sequence based on the local scene operator; determining target object information based on the target scene background and the scene image sequence, and performing air conditioning control based on the target object information to obtain an air conditioning control result.

[0063] In this embodiment of the invention, the air conditioning control device 100 can be an independent air conditioning control device, such as a smart terminal such as a mobile phone, tablet computer, network device, server, and smart computer that is connected to the air conditioner. Optionally, in other embodiments, the air conditioning control device can also be the air conditioning main control module inside the air conditioner.

[0064] This application provides an air conditioning control method, apparatus, device, and computer-readable storage medium, which will be described in detail below.

[0065] It will be understood by those skilled in the art that Figure 1 The application environment shown is only one application scenario related to the solution of this application and does not constitute a limitation on the application scenario of this application. Other application environments may include more than one application scenario. Figure 1 The number of more or fewer air conditioning control devices shown, or the air conditioning control network connections, for example Figure 1 Only one air conditioning control device is shown in the figure. It is understood that the scenario of the air conditioning control method may also include one or more air conditioning control devices, which are not limited here. The air conditioning control device 100 may also include a memory for storing image data and other data.

[0066] It should be noted that, Figure 1 The schematic diagram of the air conditioning control method shown is merely an example. The scenarios of the air conditioning control method described in the embodiments of the present invention are intended to more clearly illustrate the technical solutions of the embodiments of the present invention and do not constitute a limitation on the technical solutions provided in the embodiments of the present invention.

[0067] Based on the scenarios described above for air conditioning control methods, various embodiments of the air conditioning control method disclosed in this invention are proposed.

[0068] like Figure 2 As shown, Figure 2 This is a flowchart illustrating one embodiment of the air conditioning control method in this application. The air conditioning control method includes the following steps 201 to 204:

[0069] 201. Respond to the air conditioning control request and collect the scene image sequence corresponding to the air conditioning operating area;

[0070] The air conditioning control method in this embodiment is applied to an air conditioning control device. The type and number of air conditioning control devices are not specifically limited; that is, the air conditioning control device can be one or more intelligent terminals such as mobile phones, tablets, network devices, servers, and smart computers that are communicatively connected to the air conditioner. Optionally, in other embodiments, the air conditioning control device can also be the air conditioning main control module inside the air conditioner. The air conditioner can be a portable air conditioner, window air conditioner, wall-mounted air conditioner, or floor-standing air conditioner, etc., and can be any type of intelligent air conditioner with image acquisition capabilities.

[0071] Specifically, during operation, the air conditioner and air conditioning control equipment can respond to air conditioning control requests. These requests are control events that drive the air conditioner to collect scene image sequences within the air conditioning operating area, model the scene image sequences, identify target object information, and execute personalized air conditioning control. The triggering method for these air conditioning control requests is not specifically limited here; that is, the request can be triggered actively by the user, such as by clicking the air conditioning control button on the air conditioner's control panel or a remote control connected to the air conditioner. Optionally, in other embodiments, the air conditioning control request can also be triggered actively by the air conditioner itself. For example, the air conditioner may have an object control process that triggers the air conditioning control request when a target user object is detected in the air conditioning operating area.

[0072] Specifically, when the air conditioner receives an air conditioning control request, it also acquires a sequence of scene images within the air conditioning operating area associated with the air conditioner. This air conditioning operating area represents the working area where the air conditioner regulates air and temperature. In one specific embodiment, the air conditioning operating area can be a kitchen area with a complex background. The scene image sequence is obtained by the air conditioner using a preset image acquisition module to capture images of the air conditioning operating area, and may contain image information of target objects associated with the user. This preset image acquisition module can be an optical imaging module such as an infrared acquisition module or a depth camera module. For example, in one specific embodiment, the air conditioner can acquire the scene image sequence within the air conditioning operating area using an infrared image module installed on the air conditioner or installed in a distance from the air conditioner and located within the air conditioning operating area. Optionally, in other embodiments, the image acquisition module can also be installed in other smart home appliances within the air conditioning operating area, and the air conditioner obtains the scene image sequence of the air conditioning operating area through a communication connection with these smart home appliances. The target object information refers to specific action information (e.g., gesture information or body-sensing action information) associated with the user or other target objects that enable intelligent control of the air conditioner. For example, the target object information could be a specified interactive action that the user object is performing, containing specific interactive information.

[0073] 202. Perform mode background modeling on the scene image sequence based on the pixel grayscale values ​​of the scene image sequence to obtain the initial reference background of the scene image sequence;

[0074] Specifically, since the air conditioning operating area corresponding to the air conditioner may be an indoor operating area with a complex and changeable environment, and the scene image sequence is easily affected by factors such as changes in lighting, actor actions, and occlusion, it will have a significant impact on the target detection of the scene image sequence in subsequent steps. Therefore, before the air conditioning control device obtains the air conditioner to determine the target object information, it also performs mode background modeling on the scene image sequence to obtain the initial reference background of the scene image sequence.

[0075] Specifically, after acquiring the pixel grayscale value, the air conditioning control device counts the number of times that pixel grayscale value appears in the histogram of the scene image. The pixel grayscale value with the highest count is set as the reference grayscale value for the scene image sequence. An initial reference background for the scene image sequence is then constructed based on each reference grayscale value. The formula for generating this reference grayscale value is as follows:

[0076] B (x，y)，f (n)=Max[F (x，y)，f (n)]

[0077] Among them, B (x，y)，f(n) is the reference gray value, F (x，y)，f (n) represents the number of grayscale values ​​of the pixels.

[0078] Optionally, in order to reduce the modeling complexity of the mode background modeling based on pixel grayscale values, the air conditioning control device also performs mode modeling based on the first grayscale value and the second grayscale value in the pixel grayscale value to obtain the initial reference background, thereby reducing the modeling complexity and computational load of the initial reference background.

[0079] Specifically, after acquiring the scene image sequence, the air conditioning control device also collects the pixel grayscale values ​​of each scene image frame in the scene image sequence, and counts the pixel grayscale values ​​of each scene image frame to generate a scene image histogram corresponding to the scene image sequence. The pixel grayscale values ​​include a first grayscale value and a second grayscale value.

[0080] Specifically, after acquiring the scene image histogram corresponding to the scene image sequence, the air conditioning control device further determines the first pixel of the first scene image frame, as well as the first grayscale value and the first statistical count of the first grayscale value, based on the scene image histogram corresponding to the scene image sequence. Here, the first scene image frame refers to any image frame other than the current image frame in the scene image sequence. The first pixel is any pixel within the first scene image frame. The first grayscale value is the grayscale value of the pixel with the largest grayscale statistical count corresponding to the first pixel in the image sequence. The first statistical count is the number of times the first grayscale value appears in the scene image sequence.

[0081] Specifically, the air conditioning control device acquires the scene image histogram corresponding to the scene image sequence, determines the pixel grayscale value of the first pixel in each scene image frame based on the scene image histogram, acquires the statistical frequency of the pixel grayscale value in the scene image histogram, determines the grayscale statistical quantity of the pixel grayscale value, and determines the pixel grayscale value with the largest grayscale statistical quantity as the first grayscale value of the first pixel, and determines the statistical quantity of the grayscale value as the first statistical quantity of the first grayscale value.

[0082] Specifically, the air conditioning control device also acquires the second pixel of the second scene image frame in the scene image sequence, the second grayscale value of the second pixel, and the second statistical count corresponding to the second grayscale value. The second scene image frame is the next scene image frame in the scene image sequence corresponding to the first scene image frame. The second pixel is the image pixel in the second scene image frame that corresponds to the first pixel. The second grayscale value is the pixel grayscale value with the highest statistical count for the second pixel in the scene image. The second statistical count is the number of times the second grayscale value appears in the scene image sequence.

[0083] Specifically, after acquiring the first grayscale value and the first statistical count of the first grayscale value, the air conditioning control device also acquires the second grayscale value and the second statistical count of the second grayscale value. A reference grayscale value is determined by comparing the first statistical count and the second statistical count, and an initial reference background for the scene image sequence is constructed based on each reference grayscale value.

[0084] Optionally, if the second statistical quantity is less than or equal to the first statistical quantity, the air conditioning control device determines the reference gray value corresponding to the first pixel and the second pixel based on the first gray value corresponding to the first statistical quantity, and performs mode modeling on the scene image sequence based on the reference gray value to obtain the initial reference background.

[0085] Optionally, if the second statistical quantity is greater than the first statistical quantity, the air conditioning control device determines the second gray value corresponding to the second statistical quantity as the reference gray value corresponding to the first pixel and the second pixel, and performs mode modeling on the scene image sequence based on the reference gray value to obtain the initial reference background.

[0086] 203. Based on the initial reference background and the block smoothing process in the scene image sequence, a local scene operator for the target image block is obtained, and the target scene background of the scene image sequence is determined based on the local scene operator;

[0087] Specifically, after acquiring the initial reference background corresponding to the scene image sequence, the air conditioning control equipment further performs block smoothing on the scene image sequence based on the initial reference background, thereby obtaining a stable local scene operator for the target image block. Then, it performs secondary modeling based on this local scene operator to determine the target scene background of the scene image sequence. This eliminates most of the interference from dynamic background changes and illumination condition variations on the scene background, thereby improving the accuracy of subsequent background recognition.

[0088] Specifically, after acquiring the initial reference background, the air conditioning control device segments the initial reference background into blocks to obtain reference background image blocks. It then segments the scene image sequence into blocks according to the same segmentation rules to obtain target image blocks. That is, in one specific embodiment, the air conditioning control device divides the initial reference background into 9*9 rectangular image blocks, and then divides these rectangular image blocks into 3*3 region image blocks to obtain the reference background image blocks. Similarly, the air conditioning control device divides each scene image frame in the scene image sequence into 9*9 target image blocks, and then divides these target image blocks into 3*3 scene sub-image blocks to obtain the target image blocks.

[0089] Specifically, after acquiring the reference background image block and the corresponding target image block, the air conditioning control device further acquires the reference grayscale average value of the reference background image block and the scene grayscale average value of the target image block. Based on these reference grayscale average values ​​and scene grayscale average values, the scene image sequence is updated to obtain an updated image sequence. That is, the air conditioning control device compares the reference grayscale average value and the scene grayscale average value, and then smooths the target image blocks of the scene image sequence based on the comparison result, thereby obtaining smoothed target image blocks. Finally, an updated image sequence is generated based on these smoothed target image blocks.

[0090] Specifically, after acquiring the updated image sequence, the air conditioning control device also calculates the local scene operator corresponding to the smoothed target image patch in the updated scene image sequence, and generates the target scene background of the updated image sequence based on the local scene operator. That is, the air conditioning control device performs mode modeling again based on the local scene operator corresponding to each target image patch to obtain the target scene background of the updated image sequence. The local scene operator is the LBP (Local Binary Patterns) operator.

[0091] 204. Determine the target object information based on the target scene background and the scene image sequence, and perform air conditioning control based on the target object information to obtain the air conditioning control result.

[0092] Specifically, the air conditioning control equipment performs multiple background modeling operations using the grayscale statistics of the scene image sequence and local scene operators to obtain the target scene background. Then, it determines the target object information based on the target scene background and the scene image sequence, and performs air conditioning control based on the target object information to obtain the air conditioning control result.

[0093] Specifically, after acquiring the target scene background, the air conditioning control device performs target detection on the air conditioning operating area based on the scene image sequence and the target scene background. This determines the target object corresponding to the scene image sequence within the air conditioning operating area, as well as the target object's information. The target object can be a designated user within the air conditioning operating area. The target object information includes gesture or motion-sensing interaction information associated with a specific air conditioning control command.

[0094] Specifically, after acquiring the target object information, the air conditioning control device parses the target object information, identifies the air conditioning control command associated with the target object information, and controls the air conditioner through the air conditioning control command, driving the air conditioner to operate according to the operating parameters corresponding to the air conditioning control command, thereby obtaining the air conditioning operation result, thereby improving the accuracy of intelligent control of the air conditioner and avoiding misoperation of the air conditioner due to incorrect identification of the target object information.

[0095] In this embodiment, the air conditioning control device, in response to an air conditioning control request, acquires a sequence of scene images corresponding to the air conditioning operating area; performs mode background modeling on the scene image sequence based on the pixel grayscale values ​​of the scene image sequence to obtain an initial reference background; obtains a local scene operator for the target image block based on the initial reference background and the block smoothing process in the scene image sequence; determines the target scene background of the scene image sequence based on the local scene operator; determines target object information based on the target scene background and the scene image sequence; and performs air conditioning control based on the target object information to obtain the air conditioning control result. This achieves the following: after acquiring the scene image sequence collected by the air conditioner, background modeling is performed on the scene image sequence to obtain an initial reference background; block smoothing processing is performed on the scene image sequence based on the initial reference background, and the local scene operator after block smoothing is obtained; the target scene background of the scene line graphic sequence is updated based on the local scene operator, thereby improving the recognition accuracy in complex scenes, and further improving the recognition accuracy of subsequent target objects, thus improving the accuracy of air conditioning interaction.

[0096] like Figure 3 As shown, Figure 3 A flowchart illustrating an embodiment of the air conditioning control method provided in this application, which updates the scene image sequence based on the reference grayscale average value and the scene grayscale average value to obtain an updated image sequence, is shown below. Specifically, in this embodiment, the air conditioning control method further includes steps 301 to 302:

[0097] 301. Calculate the absolute value of the difference between the reference grayscale average value and the scene grayscale average value;

[0098] 302. If the absolute value of the difference is less than a preset difference threshold, the target image block in the scene image sequence is updated using the reference grayscale average value to obtain an updated image sequence.

[0099] Based on the above embodiments, in this embodiment, after obtaining the reference background image block and the corresponding target image block, the air conditioning control device further obtains the reference grayscale average value of the reference background image block and the scene grayscale average value of the target image block, and updates the scene image sequence according to the reference grayscale average value and the scene grayscale average value to obtain an updated image sequence.

[0100] Specifically, after acquiring the background image block and the target image block, the air conditioning control device also acquires the background grayscale corresponding to each image pixel in the background image block and calculates the average value of each background grayscale in the background image block to obtain the reference average grayscale value of the background image block. In addition, the air conditioning control device also acquires the pixel grayscale corresponding to each image pixel in the target image block and calculates the average value of each pixel grayscale in the target image block to obtain the scene average grayscale value of the target image block.

[0101] Specifically, after obtaining the average grayscale value of the parameters and the average grayscale value of the scene, the air conditioning control device also calculates the absolute value of the difference between the reference average grayscale value and the average grayscale value of the scene, and compares the absolute value of the difference with a preset difference threshold. Based on the comparison result, the target image block in the scene image sequence is updated to obtain a smoothed target image block. The scene image sequence is then updated based on each smoothed target image block to obtain an updated image sequence.

[0102] Optionally, if the absolute value of the difference is less than a preset difference threshold, the air conditioning control device uses the reference grayscale average value to update the target image block in the scene image sequence. That is, the air conditioning control device sets the reference grayscale average value to the updated scene grayscale average value of the target image block to obtain a smoothed target image block, and updates the scene image sequence according to the smoothed target image block to obtain an updated image sequence.

[0103] Optionally, if the absolute value of the difference is greater than a preset difference threshold, the air conditioning control device obtains the neighborhood gray value of the target image block, updates the target image block using the neighborhood gray value to obtain a smoothed target image block, and updates the scene image sequence based on the smoothed target image block to obtain an updated image sequence.

[0104] Specifically, after acquiring the updated image sequence, the air conditioning control device also calculates the local scene operator corresponding to the smoothed target image patch in the updated scene image sequence, and generates the target scene background of the updated image sequence based on the local scene operator. That is, the air conditioning control device performs mode modeling again based on the local scene operator corresponding to each target image patch to obtain the target scene background of the updated image sequence.

[0105] In this embodiment, the air conditioning control device calculates the absolute value of the difference between the reference grayscale average value and the scene grayscale average value. If the absolute value of the difference is less than a preset difference threshold, the target image block in the scene image sequence is updated using the reference grayscale average value to obtain an updated image sequence. If the absolute value of the difference is greater than the preset difference threshold, the target image block in the scene image sequence is updated based on the neighborhood grayscale values ​​of the target image block to obtain an updated image sequence. This achieves smoothing of the target image block using neighborhood feature information such as the reference grayscale average value and the scene grayscale average value before calculating the local scene operator to determine the target scene background, thereby improving the noise resistance performance during subsequent modeling.

[0106] like Figure 4 As shown, Figure 4 This is a flowchart illustrating an embodiment of the air conditioning control method provided in this application, which uses a local scene operator to determine the target scene background of a scene image sequence. Specifically, in this embodiment, the air conditioning control method further includes steps 401 to 404:

[0107] 401. Obtain the grayscale value of the center pixel and the grayscale value of the neighboring pixels of the target image block;

[0108] 402. Threshold the gray values ​​of the neighboring pixels based on the gray value of the center pixel to obtain the initial scene operator;

[0109] 403. Perform a base conversion on the initial scene operator to obtain the local scene operator corresponding to the target image block;

[0110] 404. Generate a local operator histogram corresponding to the updated scene sequence based on the local scene operator, and perform mode background modeling on the updated image sequence based on the local operator histogram to obtain the target scene background.

[0111] Based on the above embodiments, in this embodiment, after acquiring the updated image sequence, the air conditioning control device further calculates the local scene operator corresponding to the smoothed target image block in the updated scene image sequence, and generates the target scene background of the updated image sequence based on the local scene operator. That is, the air conditioning control device performs mode modeling again based on the local scene operator corresponding to each target image block to obtain the target scene background of the updated image sequence.

[0112] Specifically, the air conditioning control device acquires the center grayscale value and neighboring grayscale values ​​of the target image block in the updated image sequence. The center grayscale value is the pixel grayscale value corresponding to the center pixel of the target image block. The neighboring grayscale values ​​are the pixel grayscale values ​​corresponding to the remaining pixels adjacent to the center pixel in the target image block. For example, in a specific embodiment, the target image block is a 3x3 pixel grid image block. A pixel diagram of the target image block is shown below:

[0113]

[0114] In this diagram, pixels 1 through 9 each correspond to a pixel in the target image block. Pixel 5 is the center pixel of the target image block, and the remaining pixels in the target image block are all neighboring pixels of pixel 5. The air conditioning control device determines the grayscale value of the pixel corresponding to pixel 5 as the grayscale value of the center pixel of the target image block, and the grayscale values ​​of the pixels corresponding to the remaining pixels are determined as the grayscale values ​​of the neighboring pixels of the target image block.

[0115] Specifically, after acquiring the grayscale values ​​of the center pixel and neighboring pixels, the air conditioning control device performs thresholding processing on these values ​​to obtain an initial scene operator. That is, the air conditioning control device performs local binary mode processing on the grayscale values ​​of the center pixel and neighboring pixels to obtain the initial scene operator. The calculation formula for this initial scene operator is shown below:

[0116]

[0117] Among them, h C h represents the grayscale value of the center pixel. N This represents the grayscale value of the neighboring pixels.

[0118] That is, after acquiring the grayscale values ​​of the center pixel and neighboring pixels, the air conditioning control device performs differential processing based on these two values. If the grayscale value of a neighboring pixel is greater than that of the center pixel, it is recorded as 1; if it is less than that of the center pixel, it is recorded as 0, thus generating a binary initial scene operator. In one specific embodiment, the target image block is a 3*3 pixel scene image block, and the corresponding initial scene operator is an eight-bit binary parameter.

[0119] Specifically, after obtaining the initial scene operator, the air conditioning control device also performs a base conversion on the initial scene operator, converting it into a decimal number to obtain the local scene operator corresponding to the target image block.

[0120] Specifically, after acquiring the local scene operator corresponding to each target image block, the air conditioning control device generates a local operator histogram corresponding to that local scene operator. Based on this local operator histogram, it performs mode background modeling on the updated image sequence to obtain the target scene background. That is, based on the local operator histogram, the air conditioning control device reads the local scene operator corresponding to any target pixel in the updated image sequence across different scene image frames. It then determines the most frequently occurring scene local operator as the background scene operator corresponding to that target pixel, and summarizes the background scene operators for each target pixel to obtain the target scene background of the updated image sequence.

[0121] In this embodiment, the air conditioning control device acquires the grayscale value of the center pixel and the grayscale value of neighboring pixels of the target image block; thresholds the grayscale values ​​of the neighboring pixels based on the grayscale value of the center pixel to obtain an initial scene operator; performs a base conversion on the initial scene operator to obtain a local scene operator corresponding to the target image block; generates a local operator histogram corresponding to the updated scene sequence based on the local scene operator; and performs mode background modeling on the updated image sequence based on the local operator histogram to obtain the target scene background. This achieves background modeling without relying on prior information and can eliminate most of the interference from dynamic background changes and lighting conditions on image recognition, improving the accuracy of target object recognition in subsequent complex environments.

[0131] If the second statistical quantity is greater than the first statistical quantity, then the mode model is performed on the scene image sequence based on the second gray value to obtain the initial reference background.

[0136] The gray value of the pixel with the largest number of gray-scale statistics is determined as the first gray value of the first pixel, and the number of gray-scale statistics is determined as the first statistical number of the first gray value.

[0137] In one possible implementation of this embodiment, the air conditioning control device obtains a local scene operator for the target image block based on the initial reference background and the block smoothing process in the scene image sequence, and determines the target scene background of the scene image sequence based on the local scene operator, including:

[0138] The initial reference background is segmented to obtain a reference background image block, and the scene image sequence is segmented to obtain a target image block;

[0139] Obtain the average reference grayscale value corresponding to the reference background image block, and the average scene grayscale value of the target image block;

[0140] The scene image sequence is updated based on the reference grayscale average value and the scene grayscale average value to obtain an updated image sequence;

[0141] Calculate the local scene operator corresponding to the target image patch in the updated scene image sequence, and generate the target scene background of the updated image sequence based on the local scene operator.

[0142] In one possible implementation of this embodiment, the air conditioning control device updates the scene image sequence based on the reference grayscale average value and the scene grayscale average value to obtain an updated image sequence, including:

[0143] Calculate the absolute value of the difference between the reference grayscale average value and the scene grayscale average value;

[0144] If the absolute value of the difference is less than a preset difference threshold, the target image block in the scene image sequence is updated using the reference grayscale average value to obtain an updated image sequence; if the absolute value of the difference is greater than the preset difference threshold, the target image block in the scene image sequence is updated based on the neighborhood grayscale value of the target image block to obtain an updated image sequence.

[0145] In one possible implementation of this embodiment, the air conditioning control device obtains a local scene operator for the target image block based on the initial reference background and the block smoothing process in the scene image sequence, and determines the target scene background of the scene image sequence based on the local scene operator, including:

[0149] The local scene operator generates a local operator histogram corresponding to the updated scene sequence based on the local operator histogram, and performs mode background modeling on the updated image sequence based on the local operator histogram to obtain the target scene background.
