Abstract
The present invention relates to the field of home theft prevention, and provides an unlocking method, and door lock. The method comprises: recording a predetermined matching face for unlocking, and a minimum ratio of a mouth width to a face width; reading a face of a user, and identifying whether the face matches the predetermined face for unlocking; if not, remaining in a locked state; if so, then determining whether a ratio of a mouth width to a face width of the user is greater than the predetermined minimum ratio of a mouth width to a face width; if not, remaining in a locked state; and if so, unlocking. By matching a door lock of a user to their face, the present invention determines whether a person requesting unlock is the user themselves, and also ensures, by means of determination based on a minimum ratio of a mouth width to a face width of the user, that a smile of the user is read before unlocking the door lock, thus enabling face-based unlocking, and reminding the user to have a good mood before entering home.
Description
本发明属于家庭防盗领域，尤其是涉及 一种解锁方法以及门锁 。 The invention belongs to the field of home security, and in particular relates to an unlocking method and a door lock.
我们都知道一个人的姿势或者表情在某种程度上投射出一个人内心的想法。其实不仅仅是这样，一个人的姿势（表情）还能反过来影响其心态。经心理学研究发现，人们的情绪可以由动作而牵动，如故意开口大笑时，心情会变好，心理学的一个方向——情绪心理学，就包含大量人们主动调节心态和情绪的大量研究，其一个结论就是当人们在无压力的环境下，无意识甚至是被动发笑的时候，情绪会得到改善，并且影响周边的人同样改善大家的情绪。We all know that a person's posture or expression projects a person's inner thoughts to some extent. In fact, it is not only that, a person's posture (expression) can in turn affect his mentality. According to psychological research, people's emotions can be affected by movements. If you intentionally make a big laugh, your mood will get better. One direction of psychology, emotional psychology, involves a lot of people who actively adjust their mindset and emotions. One of the conclusions is that when people are unconscious or even passively laughing in a stress-free environment, their emotions will improve, and those who influence them will also improve their emotions.
试想在人们投入繁忙工作一整天后，回到家门，心情可能由于疲劳、奔波已经处于并非最佳状态，如果带着这份心情走进家门，那么回到家后的生活可能会打折扣，带着这种情绪见家人，还会无形中影响一家人的心情。而如果人们进家前，就带着好心情，充满笑容迎接繁忙工作后的家庭生活，那么则可以提升自己和家人的生活质量。Imagine that after people have been busy working for a whole day, they will return to their homes. The mood may be in an inferior state due to fatigue and rushing. If you walk into your home with this feeling, your life after returning home may be discounted. This kind of emotion sees the family and will affect the mood of the family invisibly. And if people come to their homes with a good mood and a smile to meet the family life after busy work, then they can improve the quality of life of themselves and their families.
综上，针对于当前用户回家前情绪需要改善的需求，需要提供一种结合笑容判断而解锁的方法。In summary, in order to meet the needs of the current user's emotional needs before going home, it is necessary to provide a method of unlocking in conjunction with smile judgment.
本发明实施例提供了一种解锁方法 ， 目的在于
