[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0027] In the embodiment, Figure 1-5 A shared intelligent electric oven controlled based on graphic recognition technology is provided, the present invention comprises an electric oven main body 1, a controller 3 with multiple processors and storages built in, and a communicator 4 connected to a cloud service terminal through signals, the controller 3 is connected to the communicator 4 by signal, a target detection and recognition module and a target recognition result processing module are arranged in the controller 3, an electric control box 2 is fixedly connected to the bottom of the electric oven main body 1, a loudspeaker 5 connected to the target recognition processing module signal is fixedly connected to the inside of the electric control box 2, a support frame 7 is fixedly connected to the top of the electric oven 1, a first high-definition camera 8 is fixedly connected to the inner top wall of the support frame 7, a tilting block is fixedly connected to the side wall of the support frame 7, and a second high-definition camera 9 is fixedly connected to the outside of the tilting block.
[0028] Specifically, refer to Figure 1 An electric oven 10 is arranged inside the electric grill table body 1, an oil leakage hole 11 is arranged inside the electric grill table body 1, a collecting box 12 is slidably connected to the bottom of the electric grill table body 1, a QR code label 13 is fixedly connected to the side wall of the support frame 7, a display 14 is arranged on the side wall of the electric control box 2, and a control button 15 connected to the signal of the controller 3 is arranged on the side wall of the electric control box 2.
[0029] Specifically, refer to Figure 3 The controller 3 is fixedly connected to the inside of the electric control box 2 , the communicator 4 is fixedly connected to the inside of the electric control box 2 , and a battery 6 is arranged inside the electric control box 2 .
[0030] In this embodiment, in actual use, the first high-definition camera 8 captures the image of the object. The first high-definition camera 8 pre-processes the collected object image data and sends it to the cloud service terminal through the communicator 4. The cloud service terminal uses the CSPDarknet backbone network to extract image features, locates and classifies the target through the target detection model, removes duplicate recognition results by performing non-maximum suppression, and then obtains the optimal recognition result by post-processing the confidence, and transmits the data result to the target recognition result processing module.
[0031] After receiving the data result, the target recognition result processing module executes the following steps: when it is a heatable item, the loudspeaker 5 is used to remind the user that the user can continue normal operation and complete the heating of the food; when it is a non-heatable item, the loudspeaker 5 is used to remind the user that the item is not suitable for heating and the heating operation is terminated.
[0032] It should be noted that the user scans the QR code label 13 through the mobile terminal and synchronizes it to the cloud server for model matching. The user authorizes the use and pays the fee. During the baking process, it is heated after being recognized by the target recognition result processing module. If the user does not process it after the reminder, a refund will be initiated and the power supply will be interrupted.
[0033] The training method of the target detection model is as follows: the samples are divided into two types: positive samples, which can be placed in electric oven pictures and manually labeled information; and negative samples, which cannot be placed in electric oven pictures and manually labeled information. The data trained by manual labeling are integrated into a data set, and the data set is divided into a training data set and a test training set. The Yo l ov8 detection algorithm is used to receive the training data set to obtain the model structure, which is evaluated by comparing it with the test training set to optimize the target detection model.
[0034] The preprocessing methods for the object images include: rotating each object image at multiple angles, performing multiple brightness processing, performing multiple color processing, performing multiple contrast processing, and performing multiple sharpness processing, segmenting the object images, separating food from cooking utensils, and performing image recognition and classification respectively.
[0035] Image recognition-based security control is added to the objects entering the electric grill table body 1. The purpose is to identify objects that are not suitable for entering the electric grill and classify their security levels. For example, objects that are completely prohibited from entering are classified as dangerous, such as plastic tableware, glassware, eggs in shells, grapes, etc., and their entry can be restricted. After entering, an alarm will be issued or the system will not work; for objects that can enter but need to be restricted in time, they will be classified as key attention categories, and the range of the heating time that can be set after they enter will be limited; safe objects are also classified as safe categories, and a wider heating time is given.
[0036] Conventional smart electric ovens are equipped with temperature sensors, which collect temperature information of ingredients during cooking. Together with the second high-definition camera 9, they can perform secondary identification and detection of ingredients, thereby preventing bad users from placing dangerous objects in shared smart ovens by deceptive means, and reducing safety risks caused by humans.
[0037] The controller 3 is connected to the electronic terminal signal through the communicator 4. The electronic terminal can be a mobile phone or a tablet, so that the operator can control the food baking status in the electric grill main body 1 on the electronic terminal.
[0038] Working principle:
[0039] The user places the cooking utensils and food under the first high-definition camera 8. The user scans the QR code label 13 through the electronic terminal, enters the mini program, and synchronizes to the cloud server for model matching. The user authorizes the use and pays the fee. After receiving the command, the controller 3 uses the first high-definition camera 8 to capture the image of the object, and sends it to the cloud service terminal through the communicator 4 after pre-processing. The cloud service terminal uses the CSPDarknet backbone network to extract image features, locates and classifies the target through the target detection model, removes duplicate recognition results by non-maximum suppression, and then obtains the optimal recognition result through confidence post-processing. The data result is transmitted to the target recognition result processing module. After receiving the data result, the target recognition result processing module executes the following steps: when it cannot be heated, a refund is initiated, and the user is warned through the loudspeaker 5 that there are non-heatable items, reminding them not to occupy space for a long time. When it can be heated, heating is started to complete the meal.
[0040] The user can adjust the baking condition through the control button 15, or remotely adjust the baking condition through the electronic terminal. At the same time, when the temperature in the electric oven is abnormal, the second high-definition camera 9 performs secondary recognition and detection of the food being baked according to the image recognition technology, and urgently interrupts the heating, and reminds the user and management personnel on the electronic terminal, and reminds the attention of people around the electric baking table body 1 through the loudspeaker 5.
