[0047] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0048] The range hood installation pre-survey method provided in this application can be applied to Figure 1 In the application environment shown. The terminal 102 communicates with the server 104 through the network, and the terminal 102 acquires the data (for example, image information of the installation environment). The terminal 102 can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, and portable wearable devices, and the server 104 can be implemented by an independent server or a server cluster composed of multiple servers.

[0049] In one embodiment, Figure 2 As shown, a range hood installation pre-survey method is provided, and the method is applied to Figure 1 The terminal in is used as an example to illustrate, including the following steps:

[0050] Step S210, obtaining image information of the installation environment for installing the range hood. In one example, obtaining refers to the terminal receiving image information sent by the terminal through the network. In another example, obtaining refers to the terminal retrieving image information of the installation environment from the storage thereon. It should be noted that the image information of the installation environment is a picture or video taken using the terminal. The installation environment refers to the space used to install the range hood. Generally, the installation environment is located above the stove in the kitchen, the range hood is hung on the wall, and all or part of the range hood is accommodated in the installation cabinet (the installation cabinet is part of the kitchen storage cabinet). The captured image information of the installation environment includes at least the surface to be installed and the installation cabinet for accommodating part or all of the range hood. In other words, when capturing the image information of the installation environment, at least the installation surface and the installation cabinet need to be captured therein. Among them, the installation cabinet is set on the surface to be installed. The surface to be installed is used to install the range hood.

[0051] In one example, the step of obtaining image information of the installation environment for installing the range hood includes the steps of: starting an application corresponding to the range hood; turning on the camera function of the application to obtain image information of the installation environment for installing the range hood. It should be noted that the application of the present application serves the range hood and realizes networking between the range hood, the terminal and the server. The terminal can use the application to control the range hood and realize data transmission with the server. The application is embedded with a camera function, through which the camera on the terminal can be started to collect image information of the installation environment.

[0052] In one example, the range hood includes an air suction port, an air duct, and a smoke exhaust fan (not shown in the figure). The air suction port is connected to the air duct, and the range hood sucks the oil smoke through the air suction port and discharges the oil smoke into the air duct. The air duct is connected to the outside world or the main air duct of the house, so that the oil smoke is discharged from the house. It should be noted that the air suction port of the range hood is flat and long, and the diameter of the air suction port is small. When the wind speed provided by the smoke exhaust fan is the same, the negative pressure generated at the air suction port of the range hood is greater than the negative pressure generated by the air suction port with a large diameter, which is more conducive to the extraction of oil smoke. The smoke exhaust fan is arranged in the air duct. When the smoke exhaust fan is working, it drives the air in the air duct to flow outward, thereby providing suction force for the range hood to extract oil smoke. When the back pressure of the range hood is very large (for example, when the range hood is just powered on), the exhaust fan runs at a lower speed and outputs a lower air volume. It takes a long time to drive the gas in the air duct to flow, resulting in poor fume extraction effect of the range hood during this period. It may even happen that cooking is completed but the gas in the air duct does not flow well. If the fume is to be discharged, the range hood needs to continue to run, resulting in a waste of electricity. However, if the range hood is turned off immediately after cooking is completed, the fume will accumulate in the air duct, which will cause the air duct to be blocked for a long time, and even the fume will flow back into the kitchen.

[0053] Step S220, based on the shooting angle of the image information, the image information of the installation environment is processed, and the cabinet size information of the installation cabinet is obtained. When the terminal shoots the image information of the installation environment, it detects its own posture to obtain the shooting angle, and writes the shooting angle into the image information. After the terminal obtains the image information of the installation environment, it can identify the shooting angle therein. Based on image recognition and processing technology, the terminal processes the image information of the installation environment, measures the cabinet size information of the installation cabinet, and determines whether the current installation cabinet is sufficient to accommodate the range hood. In one example, the cabinet size information includes the external dimensions and internal dimensions of the installation cabinet. Among them, the external dimensions include the length, height, and depth of the outside of the installation cabinet (the appearance of the installation cabinet). The internal dimensions include the length, height, and depth of the inside of the installation cabinet (the internal space of the installation cabinet).

[0054] In order to more accurately measure the size of the installation cabinet, in one example, the image information also includes a standard reference object. It should be noted that in the process of capturing the image information of the installation environment, the image is captured using a standard reference object, which is placed in the installation environment of the range hood. The standard reference object can be placed on the stove or on the cabinet. However, when capturing the image information of the installation environment, the standard reference object needs to be captured in the image information. The size of the standard reference object in a certain direction is known and fixed, for example, its height is known. For example, a standard soda bottle can be used as a standard reference object.

[0055] In this example, based on the shooting angle of the image information, the image information of the installation environment is processed to obtain the cabinet size information of the installation cabinet: the reference size information of the standard reference object is used as a reference, based on the shooting angle of the image information, the image information of the installation environment is processed to obtain the cabinet size information of the installation cabinet. It can be understood that the size of the standard reference object in a certain direction is known, and the known size is used as the reference size information to calculate the various sizes in the cabinet size information of the installation cabinet, so as to accurately measure the size of the installation cabinet.

[0056] Step S230, compare the cabinet size information with the range hood size information of the range hood to obtain cabinet modification information. Generally, the installation cabinet is used to accommodate the old range hood, which is now replaced with the range hood of this application, or the user has made the installation cabinet in advance after learning the size of the range hood of this application, which may not match the size of the range hood of this application. Therefore, the various dimensions in the cabinet size information are compared with the various dimensions of the range hood size information, specifically, the length, height and depth of the internal dimensions of the installation cabinet are compared with the length, height and depth of the range hood. If one or several dimensions of the range hood are larger than the corresponding internal dimensions of the installation cabinet, it means that the current installation cabinet cannot accommodate the range hood and the installation cabinet needs to be modified. For example, if the length of the range hood is larger than the length of the installation cabinet, the length direction of the installation cabinet needs to be modified. Therefore, the cabinet modification information at least includes the cabinet modification position and the cabinet modification size. It should be noted that the cabinet modification position can be the left or right side in the length direction, the upper or lower side in the height direction, or the depth direction according to the comparison. The cabinet modification size can be the lengthened size in the length direction, the heightened size in the height direction, or the deepened size in the depth direction according to the comparison.

[0057] In order to more intuitively show the installation cabinet needs to be modified, so as to better guide the installer to install. In an example, Figure 3 As shown, the step of comparing the cabinet size information with the range hood size information of the range hood to obtain the cabinet modification information includes the steps of:

[0058] Step S310, based on the image information and cabinet size information of the installation environment, simulation is performed to form a three-dimensional environment model of the installation environment. It should be noted that the image information and cabinet size information of the installation environment are simulated using three-dimensional simulation technology to form a three-dimensional environment model. In one example, the installation environment is drawn in the three-dimensional environment model using thin lines. In one example, the three-dimensional environment model includes at least a virtual surface to be installed and a virtual installation cabinet. In order to facilitate the installer to view the dimensions of each position, in one example, each structure of the virtual installation cabinet is displayed with cabinet size information, for example, the length dimension is displayed in the length direction of the virtual installation cabinet, the height dimension is displayed in the height direction of the virtual installation cabinet, and the depth dimension is displayed in the depth direction of the virtual installation cabinet.

[0059] Step S320, obtaining a 3D range hood model of the range hood, adjusting the placement angle and orientation of the 3D range hood model relative to the virtual installation cabinet, and embedding the 3D range hood model into the virtual installation cabinet for accommodating the range hood. After obtaining the virtual 3D environment model, the terminal retrieves the 3D range hood model of the selected range hood from its internal memory, embeds the 3D range hood model into the 3D environment model, and adjusts the placement angle and orientation of the 3D range hood model relative to the virtual installation cabinet, so as to place the 3D range hood model into the cabinet of the virtual installation cabinet at the angle and in the manner in which it is actually installed.

[0060] Step S330, based on the relatively placed 3D range hood model and the virtual installation cabinet, compare the cabinet size information with the range hood size information of the range hood to obtain the cabinet modification information. After the 3D range hood model is placed in the accommodation space of the virtual installation cabinet, the cabinet size information is compared with the range hood size information of the range hood through the 3D model, and the part that needs to be displayed in the installation cabinet is displayed in a visual manner, for example, the part of the 3D range hood model that exceeds the installation cabinet in the length direction is displayed in red, and the virtual installation cabinet is extended on this side at the same time to form a part that needs to be installed and modified, and the part that needs to be installed and modified is displayed in green to include the red part in the virtual installation cabinet.

[0061] In order to further accurately determine the actual size of the part that needs to be modified when installing the cabinet, so as to more accurately determine and calculate the size of the part that needs to be installed and modified, in one example, Figure 4 As shown, after the step of comparing the cabinet size information with the range hood size information of the range hood to obtain the cabinet modification information, the step further includes:

[0062] Step S410, after obtaining the cabinet modification information, adjust the shooting angle to obtain secondary image information of the cabinet modification position. After determining the part of the installed cabinet that needs to be modified, adjust the shooting angle to re-shoot the image information of the position on the installed cabinet that needs to be modified, so as to more clearly display the structure of the part that needs to be modified, thereby more accurately measuring the size of the part that needs to be modified on the installed cabinet. It should be noted that the adjustment of the shooting angle is adjusted according to the light and the direction of the part that needs to be modified, so as to better see the structure of the part that needs to be modified.

[0063] Step S420: Based on the adjusted shooting angle, the secondary image information is processed to obtain the corrected size information of the cabinet modification position.

[0064] Step S430, modifying the cabinet modification dimensions based on the modified dimension information to obtain the modified cabinet modification dimensions.

[0065] In one example, the image information at least includes a stove and a surface to be installed for installing the range hood. In the process of capturing the image information of the installation environment, both the stove and the surface to be installed are captured in the image information.

[0066] like Figure 5 As shown, the example includes the steps of:

[0067] Step S510, based on the shooting angle of the image information, the image information of the installation environment is processed to obtain the stove position information of the stove in the stove and the stovetop position information of the stovetop, as well as the installation surface size information of the surface to be installed. When the terminal shoots the image information of the installation environment, it will detect its own posture to obtain the shooting angle, and write the shooting angle into the image information. After the terminal obtains the image information of the installation environment, it can identify the shooting angle therein. Based on the image recognition and processing technology, the terminal processes the image information of the installation environment, identifies the stove position information of the stove, the stovetop position information of the stovetop, and the installation surface size information. Among them, the stove position information may include the position information of the stove in the length direction of the stovetop, for example, the position information of the bisector perpendicular to the stovetop in the length direction of the stovetop, and may also include the length of the stove. The stovetop position information may be the position of the stovetop relative to the surface to be installed, for example, the vertical distance between the stovetop and the highest point of the surface to be installed. The installation surface size information may be the length of the surface to be installed and the height from the stovetop.

[0068] In order to more accurately measure the size of the installation cabinet, in one example, the image information also includes a standard reference object. It should be noted that in the process of capturing the image information of the installation environment, the image is captured using a standard reference object, which is placed in the installation environment of the range hood. The standard reference object can be placed on the stove or on the cabinet. However, when capturing the image information of the installation environment, the standard reference object needs to be captured in the image information. The size of the standard reference object in a certain direction is known and fixed, for example, its height is known. For example, a standard soda bottle can be used as a standard reference object.

[0069] In this example, based on the shooting angle of the image information, the image information of the installation environment is processed to obtain the stove position information of the stove in the stove and the stove position information of the stove top, as well as the installation surface size information of the surface to be installed: based on the reference size information of the standard reference object, the image information of the installation environment is processed based on the shooting angle of the image, and the stove position information of the stove in the stove and the stove top position information of the stove top, as well as the installation surface size information of the surface to be installed are obtained. For example, the stove position information includes the position of the stove in the length direction of the stove. The stove top position information includes the height from the stove top to the ground or the distance from the stove top to the roof. The installation surface size information includes the length of the surface to be installed and the height from the stove top to the roof. Of course, the ground or the roof is used as a reference, and the ground or the roof needs to be photographed into the image information. It can be understood that the size in a certain direction of the standard reference object is known, and the known size is used as the reference size information to calculate the stove position information of the stove, the stove top position information of the stove top, and the installation surface size information of the surface to be installed.

[0070] Step S520, based on the stove position information, the stove top position information, the installation surface size information, the range hood size information of the range hood, and the installation requirement information, obtain the installation information of the range hood. Obtain the dimensions used to locate the installation position of the range hood in the installation environment, and simulate the installation information of the range hood using the stove position information, the stove top position information, the installation surface size information, and the range hood size information of the range hood, combined with the installation requirements of the range hood. In one example, the installation information includes at least the installation height of the range hood from the stove top and the installation position of the range hood on the surface to be installed relative to the stove. In another example, the installation information also includes the arrangement of the exhaust pipe of the range hood and the digging position of the connection hole of the exhaust pipe. In one example, the installation information also carries the material and properties of the surface to be installed (for example, a load-bearing wall or a non-load-bearing wall).

[0071] It should be noted that the installation requirement information is the way to install the range hood under ideal conditions. However, due to various installation environments, sometimes the range hood cannot be installed in the ideal way. Therefore, the installation requirement information is corrected based on the specific stove position information, stove surface position information, installation surface size information, and range hood size information of the range hood to obtain the actual installation information of the range hood.

[0072] In order to more accurately remodel the installation cabinet and install the range hood according to the installation information obtained, in this example, the cabinet size information is compared with the range hood size information of the range hood, and in the step of obtaining the cabinet modification information: based on the installation information, the cabinet size information is compared with the range hood size information of the range hood to obtain the cabinet modification information. In other words, the range hood is first installed on the surface to be installed according to the installation information, and based on the installation position of the range hood installed according to the installation information, the cabinet size information is compared with the range hood size information of the range hood. The comparison process is the same as that in the above embodiment, and will not be repeated here.

[0073] In order to more intuitively display the dimensions of the installation environment and the installation position of the range hood according to the installation information, so as to better guide the installer to install. In one example, based on the installation information, after comparing the cabinet size information with the range hood size information of the range hood, the step of obtaining the cabinet modification information also includes the following steps:

[0074] Based on the stove position information, cooktop position information, installation surface size information, range hood size information, installation information, cabinet size information, cabinet modification information and the three-dimensional range hood model of the range hood, a three-dimensional installation model of the range hood is created. Using three-dimensional simulation technology, the model forms a three-dimensional installation module. The three-dimensional installation model includes a virtual stove, wall, range hood, exhaust pipe and connection hole. In addition, the stove position information, cooktop position information, installation surface size information, range hood size information, installation information, cabinet size information and cabinet modification information are also displayed in the corresponding positions of the three-dimensional installation model. It is also necessary to arrange appropriate installation labor according to the material and properties of the surface to be installed.

[0075] In order to arrange suitable installation personnel, in one example, after the step of obtaining the cabinet modification information by comparing the cabinet size information with the range hood size information of the range hood based on the installation information, the following steps are included: based on the installation information and the cabinet modification information, a list of installation work requirements is generated. The modification of the installation cabinet may be involved. If the installation cabinet is made of wood, a carpenter needs to be arranged. If the installation cabinet is made of cement, a cement worker needs to be arranged. Suitable installation personnel need to be arranged according to the material and properties of the surface to be installed. The required types of work are listed in a list to guide the arrangement of installation personnel for on-site installation.

[0076] In one example, after the step of creating a 3D installation model of the range hood based on stove position information, stove top position information, installation surface size information, range hood size information, installation information, cabinet size information, cabinet modification information, and a 3D range hood model of the range hood, the step further includes: uploading the 3D installation model to a server. The 3D installation model simulated by the terminal is uploaded to the server, which is managed by a seller or manufacturer of the range hood, and the seller or manufacturer prepares for installation according to the 3D installation model.

[0077] In each embodiment of the range hood installation pre-survey method of the present application, image information of the installation environment for installing the range hood is obtained; based on the shooting angle of the image information, the image information of the installation environment is processed to obtain the cabinet size information of the installation cabinet; the cabinet size information is compared with the range hood size information of the range hood to obtain the cabinet modification information. Therefore, the range hood installation pre-survey method of the present application can survey the installation environment of the range hood in advance by professional installation surveyors, and upload the survey data to the server to guide the installation personnel to install the range hood, improve the installation success rate, avoid repeated rework during the installation process, improve installation efficiency, and save installation time.

[0078] It should be understood that although Figure 2-5 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. Moreover, Figure 2-5 At least part of the steps may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least part of the sub-steps or stages of other steps.

[0080] The data acquisition module 61 is used to acquire image information of an installation environment for installing the range hood; the image information at least includes a surface to be installed and an installation cabinet for accommodating a part or all of the range hood; the installation cabinet is arranged on the surface to be installed; the surface to be installed is used to install the range hood;
