And processing the moving tracks in the second moving track set through a clustering analysis algorithm to determine the target moving track.
In this embodiment, the moving track of the target object in the cooking cavity is obtained, the image information in the cooking cavity is collected by the image obtaining device, and the image information collected by the image obtaining device is processed according to the pre-existing image analysis rule in the cooking appliance, so that the moving track of the target object in the image information is determined. By determining the target movement track by using the image acquisition device, whether the cooking appliance is inclined or not is determined without arranging an accelerometer in the cooking appliance.
The image information acquired by the image acquisition device comprises a large number of objects, and the movement tracks of the objects included in the image information are identified and extracted by an image identification technology to form a first movement track set. Because the first moving track set comprises a large number of moving tracks, the similarity of the moving tracks in the first moving track set is determined, and the moving tracks in the first moving track set are screened according to the determined similarity, so that the second moving track set is obtained by screening, and the influence of part of irregular moving tracks on the accuracy of the judgment result is reduced. And processing the moving tracks in the second moving track set with higher similarity through a clustering analysis algorithm, thereby determining the target moving track. By collecting a large number of samples of the moving track of the target object and analyzing the large number of samples, the accuracy and consistency of whether the cooking utensil is inclined or not are improved.
In any of the above embodiments, the image information acquired by the image acquiring device can also be used to determine whether the food material in the cooking cavity has been cooked to the target state, and determine that the cooking appliance has finished cooking the food material according to the food material reaching the target state.
In this embodiment, the food material image in the image information is extracted, and whether the food material in the cooking cavity is in the target state or not can be judged according to the model and the food material image stored in the local storage area. And when the food material in the cooking cavity is judged to be in the target state, controlling the cooking appliance to enter a cooking ending state. And when the food material in the cooking cavity is judged not to be in the target state, controlling the cooking appliance to continuously operate in the cooking state. Whether the food materials in the cooking cavity reach the target state or not is judged according to the image information collected by the image acquisition device, and the fact that whether the cooking appliance is in an inclined arrangement state or not and the cooking state of the food materials in the cooking appliance can be judged is achieved through the image information collected by the image acquisition device. Integrate a plurality of functions on same structure, when having improved cooking utensil functionality, reduced cooking utensil's manufacturing cost.
