Method and device for adjusting light intensity of light supplement lamp based on gray value and refrigerator

Abstract

The invention discloses a method and device for adjusting the light intensity of a light supplement lamp based on a gray value and a refrigerator, and the method comprises the steps: training a relation curve E = f (delta G) between the gray value difference delta G of an ROI region of a shot image in the refrigerator and the light intensity E of the light supplement lamp to be subjected to light supplement, wherein, the gray value difference value delta G is a difference value between a gray value threshold value G0 and an actual gray value G1 of the ROI region; obtaining an actual gray value G1 of the ROI region of the image to be recognized, and calculating a gray value difference value delta G1 = G0-G1; according to the delta G1 and the relation curve E = f (delta G), calculating the light intensity E1 of the light supplementing lamp to be subjected to light supplementing, and adjusting the light intensity of the light supplementing lamp according to the E1. Compared with the prior art, the method for adjusting the light intensity of the light supplementing lamp based on the gray value has the advantages that the light intensity of the light supplementing lamp can be rapidly adjusted, lighting in a refrigerator is sufficient, the quality of a shot image is improved, the recognition rate of food materials in the shot image is increased, the recognition result can be rapidly fed back to a user, and the user experience feeling is improved.

Description

technical field [0001] The invention relates to the field of home appliances, in particular to a method, device and refrigerator for adjusting the light intensity of supplementary light based on a gray value. Background technique [0002] With the development of science and technology, the intelligentization of refrigerators has become an inevitable trend. The so-called smart refrigerator is a type of refrigerator that can intelligently control the refrigerator and intelligently manage food. To be more specific, it can automatically switch the refrigerator mode to keep the food in the best storage state at all times, allowing users to know the quantity of food in the refrigerator, freshness and quality information anytime, anywhere through mobile phones or computers, and can provide users with healthy recipes and nutrition. Taboo, you can remind users to replenish food regularly. [0003] In order to realize the above functions, it is an indispensable way to install a came...

Problems solved by technology

The image taken inside the refrigerator is prone to insufficient lighting, which can be divided into many situations. For example, after the refrigerator door is closed, in order to save electricity, the light source in the refrigerator will gradually weaken until it is completely dark, or it will be turned off directly and quickly; Even if the light source is normal, there may be situations where the ingredients block the light and cause insufficient lighting in the refrigerator
