Detailed Description
The present invention will be described in further detail with reference to the following detailed description and accompanying drawings.
In the existing baking equipment such as an oven and a toaster, when a user uses the baking equipment, the user selects corresponding baking time according to own taste requirements, for example, the user A likes 'crisp and soft taste', the user B likes 'outer crisp and inner soft taste', and the user C likes 'sweet soft and glutinous taste', so that the user A, the user B and the user C need to select corresponding baking time according to experience, and the achieved baking effect is often difficult to meet the taste of the user. Based on this, the invention creatively proposes: the gear of the knob of the baking equipment is associated and mapped with the target baking taste and the target baking color of the food, so that a user can select the corresponding gear according to the target baking taste and the target baking color of the user's own requirements, and in the baking process, the baking parameters of the baking equipment are adjusted according to the color change of the baking process of the baked food until the current baking process color of the baked food reaches the target baking color, so that the operation flow of the user is simplified, and the baking quality of the food is improved.
The first embodiment is as follows:
the present embodiment provides a baking control method of a baking device, a flowchart of which is shown in fig. 1, and specifically includes the following steps.
S100: and acquiring controlled gear information of the baked food, and performing associated mapping on the controlled gear information, the corresponding target baking taste and the target baking color.
In order to implement the basic idea of the present invention, a large number of food baking experiments and corresponding data statistics need to be performed in the early stage, specifically, for this embodiment, baking experiments need to be performed on different taste requirements of each type of food, a large number of images are collected for a baking effect graph of each taste, and then recognition and training are performed according to the collected images; finally, the target baking color of each taste is obtained.
Taking baked bread as an example, the preparation work in the previous stage is explained:
the taste requirements of different users on the baked bread are counted, for example, the taste requirements of the users on the baked bread are counted to include: "fluffy and fine", "slightly hot and soft", "wheat-flavored and soft", "crisp outside and soft inside", "burnt and crisp and refreshing";
then, obtaining baking effect diagrams corresponding to various tastes through a large number of baking experiments aiming at the various tastes, wherein the baking effect diagrams represent corresponding baking colors;
training through color recognition and the baking color characteristic value recognized according to each taste to finally obtain the target baking color corresponding to each taste;
establishing a corresponding association relationship between the identified target baking color and the corresponding taste thereof, for example, establishing the following relationship table:
TABLE 1
Based on the establishment of the correlation relationship between the target baking taste and the target baking color of the baked food in the early stage, then, the gear of a knob in the baking equipment is set according to the target baking taste or/and the target baking color, each gear is in correlation mapping with the corresponding target baking taste and the target baking color, and a user can select the corresponding gear according to the target baking taste and the target baking color.
For example, table 2 of the target roasting flavor, the target roasting color, and the gear association map may be established as follows according to table 1 above:
TABLE 2
| Target roasting flavor | Target baking color | Knob gear of baking equipment |
| Fluffiness and fineness | Light yellow | Gear 1 |
| Slightly hot and soft | Slight yellowing | Gear 2 |
| Wheat fragrance soft | Light yellow burnt color | Gear 3 |
| Crisp outside and soft inside | Golden color | Gear 4 |
| Soft inside the outer jiao | Light brown burnt color | Gear 5 |
| Burnt, fragrant and crisp | Dark brown burnt-out color | Gear 6 |
Based on the above description, the target baking taste and the target baking color of the user can be known by obtaining the controlled gear information of the baked food, for example, when the user selects "gear 5", it can be known that the user wants the baked food to be baked to "soft inside out of the scorch" and "light brown burnt color".
S110: the type of food being baked is identified.
It should be noted that, since the earlier stage of the work classifies the target roasting taste and the target roasting color of the roasted food, specifically, the roasted food whose roasting color changes significantly with the roasting time is classified into one (called as a preset color food type), while the baked goods having no significant change in baking color with the baking time period are classified into another category, for example, the baked goods having white and yellow initial colors on the surface are classified into one category, while the baked goods whose surface is initially colored brown and black are classified into another kind, since the baked goods whose color is not changed significantly during the baking process, the baking parameters of the baking equipment can not be adjusted according to the color change of the baked food in the baking process, so the types of the baked food are firstly identified in the step, and whether the food belongs to the type of the food with the preset color is further judged through the step S120.
The process of identifying the type of food being baked is as follows:
acquiring initial image information of baked food;
extracting attribute characteristics of the baked food in the initial image information;
for example, color features of the baked good, such as color mean, color variance, color histogram, color set, color moment, etc., may be extracted;
and classifying the baked food according to the extracted attribute characteristics according to colors.
S120: and judging whether the type of the baked food belongs to a preset color food type.
The food type with the preset color has the color changing in a gradient manner along with the change of the baking time in the baking process, namely, the food with the obvious color change in the baking process is called the food type with the preset color, and bread is taken as an example, bread can be divided into white bread, yellow bread and brown bread, wherein the color of the white bread and the color of the yellow bread are obviously changed in the baking process, and the color of the brown bread (black bread) is not obviously changed in the baking process, so that the white bread and the yellow bread are arranged in the bread with the preset color type.
S130: if so, calling a target baking color corresponding to the controlled gear information according to the association mapping, and adjusting baking parameters of the baking equipment according to the color change of the baking process of the baked food until the current baking process color of the baked food reaches the target baking color.
The method comprises the following steps of adjusting baking parameters of baking equipment according to color change of baked food in a baking process, and specifically comprises the following steps:
acquiring baking process image information of baked food in an inner cavity of baking equipment in real time;
identifying image information in the baking process, and acquiring a color characteristic value of the baked food in the baking process;
and comparing the characteristic value of the color in the baking process with the characteristic value of the target baking color, and adjusting the baking parameters of the baking equipment according to the comparison result until the color of the baked food in the current baking process reaches the target baking color.
The baking parameters include, but are not limited to, baking temperature, baking duration, baking temperature control logic, etc.
The baking parameters of the baking device can be adjusted for the preset color food type through the above steps S100-S130 according to the color change of the baking process of the baked food, and for the food type not belonging to the preset color, the present embodiment adjusts the baking parameters of the baking device through the following step S140.
S140: if the food to be baked is judged not to belong to the preset color food type, the baking equipment is controlled according to the baking parameters corresponding to the controlled gear information.
For the baked food which is not in the preset color food type, the embodiment adopts the conventional mode that the gear is associated with the time to control the baking time of the baking equipment to the baked food.
In the above steps S130 and S140, the method further includes acquiring temperature information in the baking device in real time, and further adjusting baking parameters of the baking device according to the temperature information and the comparison result, so as to make the baked food reach the best baking taste.
Through the steps S100-S140, the corresponding target baking taste and the target baking color are called according to the gear information, the baking parameters of the baking equipment are adjusted by adopting the color change of the baking process of the baked food according to the type of the baked food or the baking parameters corresponding to the gears are adopted to control the baking equipment until the baked food reaches the target baking color and the target baking taste.
The following is an example of the baked product as bread with reference to table 2 above.
Acquiring controlled gear information of a gear 2;
identifying the bread to obtain white bread;
calling a target baking color corresponding to the gear 2 according to the association mapping;
and identifying the color change of the bread in the baking process, comparing the color change with the slightly yellow color, and adjusting the baking parameters of the baking equipment according to the comparison result until the bread is baked to the slightly yellow color, and ending the baking.
