This embodiment is applicable to the situation of controlling the discharge flow rate of a tobacco storage cabinet. This method can be executed by a control device for the discharge flow rate of a tobacco storage cabinet. The control device for the discharge flow rate of a tobacco storage cabinet can be implemented in the form of hardware and / or software, and the control device for the discharge flow rate of a tobacco storage cabinet can be configured in an electronic device such as a computer or a server. As Figure 1 shown, the method of this embodiment includes:

[0032] S110. During the process of conveying tobacco materials in the tobacco storage cabinet, use a depth camera to photograph the current tobacco materials in the tobacco storage cabinet to obtain a current material depth image.

[0033] Among them, the depth camera can be used to photograph the tobacco materials in the tobacco storage cabinet at the current moment. In the embodiment of the present invention, the depth camera is pre-installed at the tobacco material discharge port of the tobacco storage cabinet, see Figure 2 . In the embodiment of the present invention, the field of view of the depth camera installed at the tobacco material discharge port of the tobacco storage cabinet covers the materials on both the left and right sides of the storage cabinet. In order to improve the image shooting quality of the depth camera, one or more light sources can be arranged in the tobacco storage cabinet. Among them, the depth camera can be a 3D depth camera. In the embodiment of the present invention, the 3D depth camera can obtain the depth information of the scene of the current tobacco materials in the tobacco storage cabinet by using multiple cameras and infrared sensors. In the embodiment of the present invention, the 3D depth camera can use technologies such as structured light, time-of-flight or binocular vision to project infrared light onto the target object, and then measure and analyze the reflection time or angle difference of the infrared light, so as to calculate three-dimensional data such as the distance and position of the object, so as to obtain the current material depth image. In the embodiment of the present invention, the current tobacco materials can be understood as the tobacco materials in the tobacco storage cabinet at the current moment. The current material depth image can be understood as the material depth image obtained after photographing the tobacco materials in the tobacco storage cabinet at the current moment.

[0034] In the embodiment of the present invention, when the depth camera is pre-installed at the tobacco material discharge port of the tobacco storage cabinet, during the process of conveying tobacco materials in the tobacco storage cabinet, the depth camera can be used to photograph the current tobacco materials in the tobacco storage cabinet, that is, the current material depth image is obtained.

[0035] In the embodiments of the present invention, the number of depth cameras for photographing the current tobacco material in the tobacco storage cabinet may be one or more. When the number of cameras for photographing the current tobacco material in the tobacco storage cabinet is one, the depth image obtained by photographing the current tobacco material in the tobacco storage cabinet through the depth camera may be determined as the current material depth image. When the number of cameras for photographing the current tobacco material in the tobacco storage cabinet is multiple, multiple depth images obtained by photographing the current tobacco material in the tobacco storage cabinet by multiple depth cameras may be subjected to image fusion processing, so as to obtain a fused image. Furthermore, the fused image may be used as the current material depth image.

[0036] S120. Input the current material depth image into a pre-trained volume measurement model to obtain the current tobacco material volume of the current tobacco material.

[0037] Among them, the pre-trained volume measurement model can obtain the current tobacco material volume of the current material according to the current material depth image of the current material. The current tobacco material volume can be understood as the volume of the current tobacco material at the current moment. Specifically, a pre-trained volume measurement model can be obtained first. Then, the current material depth image can be input into the pre-trained volume measurement model to obtain the volume of the current tobacco material, that is, the current tobacco material volume.

[0038] In the embodiments of the present invention, the method for obtaining the pre-trained volume measurement model may specifically include: acquiring sample data and expected data corresponding to the sample data, where the sample data may include historical material depth images of historical tobacco materials in the tobacco storage cabinet, and the expected data may be the historical tobacco material volumes corresponding to the historical material depth images. Then, the sample data can be input into a pre-constructed network model to obtain the actual output result of the initial network model. Furthermore, based on the expected data and the actual output result, the network parameters of the initial network model can be adjusted to obtain the trained volume measurement model.

[0039] Among them, the historical tobacco material can be understood as the tobacco material in the tobacco storage cabinet at a historical moment. The historical material depth image can be understood as the material depth image obtained by photographing the tobacco material in the tobacco storage cabinet at a historical moment. In the embodiments of the present invention, the initial network model can be a deep learning model set according to actual needs, and specific limitations are not made here. In the embodiments of the present invention, optimization algorithms (such as Adam, SGD, etc.) can be used to improve the accuracy and processing speed of the model. In the embodiments of the present invention, based on the expected data and the actual output result, adjusting the network parameters of the initial network model to obtain the trained volume measurement model may include: calculating a loss function based on the expected data and the actual output result. In the case where the loss result does not reach convergence, the network parameters of the initial network model can be adjusted to obtain the trained volume measurement model. It can be understood that in the case where the loss result reaches convergence, the model training can be ended to obtain the trained volume measurement model.

[0040] S130. Obtain the current tobacco material weight of the current tobacco material based on the current tobacco material volume; adjust the transmission speed of the tobacco storage cabinet based on the current material weight to control the discharge flow rate of the tobacco material in the tobacco storage cabinet.

[0041] Among them, the current tobacco material weight can be understood as the weight of the current tobacco material in the tobacco storage cabinet at the current moment. The tobacco material discharge flow rate can be understood as the flow rate of the tobacco storage cabinet outputting tobacco material. In the embodiments of the present invention, the method for obtaining the transmission speed of the tobacco storage cabinet can specifically be to obtain it through a speed sensor pre-installed in the tobacco storage cabinet. In the embodiments of the present invention, referring to Figure 3 , the tobacco storage cabinet is provided with a bottom belt motor, and the operating frequency of the bottom belt motor can be obtained to obtain the transmission speed of the tobacco storage cabinet.

[0042] In the embodiments of the present invention, obtaining the current tobacco material weight of the current tobacco material based on the current tobacco material volume may include: determining the current tobacco material weight of the current tobacco material based on the current tobacco material volume and the material density of the current tobacco material. Specifically, the material density of the current tobacco material can be determined. Furthermore, the current tobacco material volume and the material density can be multiplied. The multiplication result obtained is used as the current tobacco material weight of the current tobacco material.

[0043] In an embodiment of the present invention, adjusting the transmission speed of the tobacco storage cabinet based on the current material weight includes: determining the current tobacco flow rate data of the tobacco storage cabinet for transporting tobacco materials based on the current tobacco material weight and the transmission speed of the tobacco storage cabinet, and adjusting the transmission speed of the tobacco storage cabinet based on the current tobacco flow rate data. Herein, the current tobacco flow rate data can be understood as the flow rate data of the tobacco storage cabinet for transporting tobacco materials at the current moment.

[0044] In an embodiment of the present invention, determining the current tobacco flow rate data of the tobacco storage cabinet for transporting tobacco materials based on the current tobacco material weight and the transmission speed of the tobacco storage cabinet can specifically be to perform a multiplication operation on the current tobacco material weight at the current moment and the transmission speed of the tobacco storage cabinet at the current moment. Thus, the result of the multiplication operation can be determined as the current tobacco flow rate data of the tobacco storage cabinet for transporting tobacco materials.

[0045] In an embodiment of the invention, adjusting the transmission speed of the tobacco storage cabinet based on the current tobacco flow rate data may include: when the current tobacco flow rate data increases, reducing the transmission speed of the tobacco storage cabinet; when the current tobacco flow rate data decreases, increasing the transmission speed of the tobacco storage cabinet.

[0046] Based on the above embodiments, the method may further include: during the process of the tobacco storage cabinet transporting tobacco materials, as Figure 2 shown, a preset camera can be used to capture the tobacco materials in the material conveying device connected to the tobacco storage cabinet to obtain a material conveying image; based on the material conveying image, determine whether there are tobacco materials in the material conveying device. If not, generate a preset prompt message and display the preset prompt message. Herein, the material conveying image can be an image obtained by a preset camera capturing the tobacco materials in the material conveying device connected to the tobacco storage cabinet. The preset prompt message can be used to prompt that there are no tobacco materials in the material conveying device connected to the tobacco storage cabinet. The preset prompt message can include at least one of an image prompt message, a voice prompt message, and a text prompt message. In an embodiment of the present disclosure, determining whether there are tobacco materials in the material conveying device based on the material conveying image may include: analyzing the material conveying image to obtain an image analysis result; thus, it can be determined whether there are tobacco materials in the material conveying device based on the image analysis result.

[0047] In the embodiments of the present invention, when the stack height shape (volume) of the tobacco in the tobacco storage cabinet changes, such as when the stack height shape changes linearly and smoothly at the head and tail of the material, or when the local collapse of the material causes an instantaneous mutation in the stack height shape, etc., the instantaneous flow data will change accordingly. In the embodiments of the present invention, not only can the discharge flow rate of the tobacco material in the tobacco storage cabinet be kept stable.

[0048] The technical solution of the embodiments of the present invention is as follows: during the process of transporting tobacco materials in the tobacco storage cabinet, a depth camera is used to capture the current tobacco materials in the tobacco storage cabinet to obtain the current material depth image; the current material depth image is input into a pre-trained volume measurement model to obtain the current tobacco material volume of the current tobacco materials; based on the current tobacco material volume, the current tobacco material weight of the current tobacco materials is obtained; and based on the current material weight, the transmission speed of the tobacco storage cabinet is adjusted to control the discharge flow rate of the tobacco materials in the tobacco storage cabinet.
