Abstract

The invention provides a virtual control panel operation recognition method and a refrigerator. The method comprises the steps of 1, projection, 2, position obtaining and 3, operation identification. In the step 1, a virtual control panel is projected into a designated area of a storage chamber based on a virtual projection module; in the step 2, when hand information of the user is captured in the designated area, finger position information of a finger of the user in the designated area is obtained; and in the step 3, the operation of the user is identified on the virtual control panel based on the finger position information, and an operation instruction corresponding to the operation provided for a main control panel of the refrigerator is generated, so that the main control panel responds to the operation instruction. Based on the scheme, the finger of the user can be recognized and tracked through a binocular distance measurement assembly, and data measured by the binocular distance measurement assembly is corrected through a laser distance measurement assembly, so that the response to misoperation of the user is reduced while the recognition accuracy is further improved, and the projection efficiency of the virtual projection module and the use experience of the user are improved.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a virtual control panel operation recognition method and a refrigerator. Background technique [0002] At present, as far as the touch technology of refrigerators is concerned, touch panels or different operation buttons are often installed on the outside of the refrigerator door or other cabinets to control the operating parameters of the refrigerator, and most of them are display panels equipped with LED lights. It is shown that its structure is simple and its function is single. [0003] With the intelligence of refrigerators, the projected virtual button technology applied to refrigerators has been proposed, and virtual operation buttons can increase user-friendly experience. However, currently commonly used detection is mostly laser detection or infrared detection, which has low accuracy in judging the position of the finger in the projection area and cannot effective...
