Method and system for controlling opening of door

Abstract

The invention discloses a method and a system for controlling opening of a door. The method is characterized by after acquiring an ROI (Region Of Interest) image of a body, calculating a height of thebody based on the ROI image of the body, on the one hand, judging whether the body is a child based on the height of the body, on the other hand, performing body classification on the ROI image of the body through a convolutional neural network model; controlling a door to be kept locked when both a judging result based on the height of the body and a body classification result based on the convolutional neural network model show that the body is a child, and otherwise, controlling the door to be unlocked. The method of the invention has the beneficial effects that: the method adopts a judging mode combining height with age; on the one hand, through judgment based on the height, a non-child group can be excluded from the height; on the other hand, through the convolutional neural network,characteristic values correlated with the age, such as clothing characteristics, appearance characteristics, height characteristics, and weight characteristics of people, are extracted to judge the classification, so as to clearly exclude the non-child group from the age, so that a classification result is close to fact and accurate, thereby preventing the child from opening the door at will, andavoiding occurrence of potential hazards.

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...

[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 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
