Door opening control method and system

Abstract

The invention discloses a door opening control method and system. The method comprises the steps of obtaining human body region-of-interest images; performing human body classification on the human body region-of-interest images by using a convolutional neural network model; when the human body classification is children, controlling a door body to be kept locked; and when the human body classification is non-children, controlling the door body to be unlocked. According to the mode for taking the shape of the whole person as a region of interest and extracting age-related eigenvalues of a clothing feature, a physical feature, a height feature, a weight feature and the like of the person through a convolutional neural network to perform judgment and classification, a classification result is closer to reality and more accurate, and a user does not need to input authorization information in advance; the mode is an accurate and efficient classification mode; the children can be preventedfrom opening the door body at will; and potential dangers are avoided.

Description

technical field [0001] The invention belongs to the technical field of image processing and recognition, and in particular relates to a door opening control method and system. Background technique [0002] The popularity of cabinets with doors and household appliances provides convenience for users, but there are also certain potential safety hazards; Possibly, if the child opens the door at this time, the head may be accidentally injured by the falling objects; injury accident. [0003] In order to avoid potential harm to children, there are some door opening control methods in the prior art, for example, using an infrared sensor to detect the height of a human body appearing in front of the door, and when the height is lower than a height threshold, the lock of the door is controlled. It is in a locked state to prevent children from opening it, but it is difficult to set the height threshold in this scheme. When the setting is low, the door cannot be opened for short adu...

[0003] In order to avoid potential harm to children, there are some door opening control methods in the prior art, for example, using an infrared sensor to detect the height of a human body appearing in front of the door, and when the height is lower than a height threshold, the lock of the door is controlled. It is in a locked state to prevent children from opening it, but it is difficult to set the height threshold in this scheme. When the setting is low, the door cannot be opened for short adults. If the setting is high, it is not conducive to protection. Children; as another example, the camera is used to obtain the user's face information to identify the user's face. Unauthorized users cannot open the door, or authorized users can open the door, but this method needs to enter the user's face in advance. internal information, setting authorization information, etc., occupying system resources and inconvenient to use
