An off-line elevator calling method based on face recognition comprises the following steps that a first information table and a second information table are constructed, the first information table is used for storing face information, ID and floor information of a user, the second information table is used for storing the number of recognition times of the face information of the user and ID, and the ID value is a unique value; whether the storage capacity of the local storage memory reaches a storage threshold value or not is judged, if the storage capacity reaches the storage threshold value, a current time point is obtained and serves as a first time point, the first information table and the second information table are associated, and when the face of the user is recognized, the number of recognized times in the second information table is updated through the ID value; and finding out the face information stored in the first information table according to the ID value, and deleting the face information so as to vacate redundant storage space. Therefore, new user face information can be input subsequently, and normal access control operation of the elevator is ensured.

    一种基于人脸识别的离线呼梯方法,包括如下步骤:构建第一信息表与第二信息表,其中第一信息表用于存储用户的人脸信息、ID以及楼层信息、第二信息表用于存储用户人脸信息被识别次数以及ID,其中ID值为唯一值;判断本地存储内存的存储量是否达到存储阈值,若达到存储阈值,则获取当前时间点,作为第一时间点,关联第一信息表与第二信息表,当用户人脸被识别时,通过ID值对第二信息表中的被识别次数进行更新;根据ID值找到第一信息表内存储的人脸信息进行删除,以空出多余的存储空间。以便后续有新的用户人脸信息录入,确保电梯的正常门禁运行。
