Embodiment 1

[0103] The application scene of the air volume control method of the range hood of the present invention is a kitchen cooking scene, such as figure 1 As shown, a represents the range hood, and the number of air ducts corresponding to the range hood is greater than or equal to two, and each air duct corresponds to a stove. The image acquisition device (such as a camera) on is used for real-time acquisition of scene images within the viewing angle range of the camera; c represents the stove, and d represents the pot placed on the stove c. Such as figure 2 As shown, the dotted line area is the cooktop area corresponding to the left and right cooktops.

[0104] Example 1

[0105] Such as image 3 As shown, the control method of the range hood air volume of the present embodiment includes:

[0106] S101. Obtain the current frame image corresponding to the cooking area;

[0107] Specifically, the camera installed on the range hood is used to collect the corresponding scene ima...

Embodiment 2

[0117] Such as Figure 4 As shown, the control method of the range hood air volume in this embodiment is a further improvement on Embodiment 1, specifically:

[0118] Step S102 includes:

[0119] S1021. Obtain a background frame image corresponding to the cooking area;

[0120] In a practicable solution, step S1021 includes:

[0121] Obtain the cooking scene frame image corresponding to the cooking scene within the historical setting time period;

[0122] Recognizing the historical frame images corresponding to the cooking area in the cooking scene frame images;

[0123] Performing grayscale transformation processing on the historical frame image, and performing frame difference processing on the historical frame image of the next frame after the grayscale transformation processing and the historical frame image of the previous frame to obtain the first frame difference image;

[0124] When the first frame difference image satisfies the preset condition, the historical frame...

Embodiment 3

[0166] Such as Figure 5 As shown, the air volume control system of the range hood in this embodiment includes a current frame image acquisition module 1, a target frame difference image calculation module 2, an initial area determination module 3, a contour detection module 4, an oil fume proportion acquisition module 5, and an air volume ratio distribution Module 6 and air volume control module 7.

[0167] The current frame image acquisition module 1 is used to acquire the current frame image corresponding to the cooking area;

[0168] Specifically, the camera installed on the range hood is used to collect the corresponding scene images in the cooking scene in real time, and then the image recognition technology is used to automatically identify the location of the cooking area in the scene image and the corresponding frame image, so as to facilitate subsequent oil fume recognition of the cooking area .

[0169] The target frame difference image calculation module 2 is use...

Abstract

The invention discloses a control method, system, electronic equipment and storage medium for the air volume of a range hood. The control method includes: acquiring a current frame image corresponding to a cooking area; calculating a target frame difference image corresponding to the current frame image; determining the current frame image The corresponding initial soot movement area; contour detection of the initial soot movement area to obtain the first soot movement area; obtain the proportion of soot corresponding to different cooktops; allocate the air volume ratio of the air duct corresponding to each cooktop according to the proportion of soot to control The air volume in the air duct corresponding to each stove. In the present invention, the oil fume motion area detection method based on the background frame is adopted to effectively improve the accuracy of the oil fume motion area detection; based on the softmax algorithm, the intelligent air volume distribution is carried out based on the intensity of the oil fume motion of different cooktops in the cooker area, so that the hood The air volume more accurately matches the current cooking conditions of the stove, so as to achieve precise smoke exhaust and avoid waste of resources.

Description

technical field [0001] The invention relates to the technical field of smart home appliances, in particular to a control method, system, electronic equipment and storage medium for the air volume of a range hood. Background technique [0002] The kitchen is a necessary scene for every family to cook every day. The effect of kitchen fume treatment directly affects the health and quality of life of family members. The traditional method of controlling the air volume of the range hood is mainly to adjust the gear position by manually controlling the gear position to adjust the air volume of the range hood. With the development of society and the progress of smart home appliances, more and more intelligent functions appear on the hood, such as the function of recognizing oil fume through the monitoring module to adjust the air volume of the hood. At present, the automatic air volume adjustment method of the hood based on image processing is to monitor in real time according to ...
