Embodiment 1

[0093] Such as figure 2 As shown, the detection method of the oil smoke concentration of the present embodiment includes:

[0094] S101, obtain the current scene frame image corresponding to the smoke stove scenario;

[0095] S102 identifies the cigarette generating area in the current scene frame image;

[0096] S103, calculate the high-frequency energy in the frequency domain of the cigarette generation region; wherein the high-frequency energy is used to characterize the edge information corresponding to the cigarette;

[0097] For the smoke image, the characterization characteristic of the cigarette in the image is to cause the edge of the image, and the edge information corresponds to the high frequency region in the image frequency domain. According to this principle, the cigarette concentration of the current image can be determined by the high-frequency energy in the statistical image frequency domain.

Embodiment 2

[0101] Such as image 3 As shown, the detection method of the oil smoke concentration of the present embodiment is to further improve the further improvement of Example 1, specifically:

[0102] Step S101 includes:

[0103] S1011, the cooking video frame image corresponding to the smoke stove scenario, and the current cooking video frame image is used as the current scene frame image corresponding to the smoke scene;

[0104] Step S102 includes:

[0105] S1021, the current scene frame image performs grayscale conversion processing to acquire the corresponding gradation image; wherein the existing image grayscale processing technique is employed, so it will not be described later.

[0106] S1022, a pot area image of the region in the gradation image is detected using the target detection algorithm, and determines the smoke generating area according to the pot region image. In addition, algorithms that can identify the area where the pot in the gradation image can be used.

Abstract

The invention discloses an oil smoke concentration detection method and system, electronic equipment and a storage medium. The detection method comprises the following steps: acquiring a current scene frame image corresponding to a range hood scene; identifying a lampblack generation area in the current scene frame image; calculating high-frequency energy of the lampblack generation area in a frequency domain, wherein the high-frequency energy is used for representing edge information corresponding to the lampblack; and determining a target oil smoke concentration in the current scene frame image according to the high-frequency energy. According to the method and system, the high-frequency energy of the lampblack image in the frequency domain is counted to judge the lampblack concentration in the current scene frame image, and the image is converted to the frequency domain for amplitude statistics, so that interference of color differences in different user environments on lampblack concentration judgment is avoided, the accuracy and reliability of lampblack concentration detection are effectively improved, the intelligent level of range hood control is guaranteed, the operation burden of a user is relieved, and the use experience feeling of the user is improved.

Description

Technical field [0001] The present invention relates to the field of cigarette identification, and more particularly to detecting methods, systems, electronic devices, and storage media for oil smoke concentrations. Background technique [0002] With the dynamic changes in the amount of fumes during the cooking process, the wind volume of the smoke needs to be adjusted according to the size of the cigarette to achieve excellent kitchen buffing effect. At present, the intelliperness of the hood belongs to the condition of the smoke or is poor performance, so that the detection effect of the smoke in the smoke perception system is very necessary. [0003] It is mainly used to detect the concentration of the smoke as follows: (1) User naked eye discriminates the kitchen oil concentration, and then manually adjusts the migratory air volume according to the discrimination; however, the detection method increases the user's work burden, low intelligence, impact The user's experience; (...
