The invention discloses an uncalibrated elevator running state recognition method supporting multiple view angles, and the recognition method comprises the following steps: S1, after recognition is started, if equipment is carried manually, a user is reminded to align a camera to an elevator panel through voice; if the equipment is the assembly of the mobile robot, the robot is notified to rotate a camera to face an elevator panel; s2, controlling a camera to take photos or videos at a certain sampling frequency, and continuously sending single-frame images to the display screen identification model; s3, eliminating interference of advertisements and the like by the display screen identification model, and outputting candidate display screen screenshots; and S4, if no candidate display screen exists, returning to the step 1. According to the method, each character can be independently recognized, the recognition accuracy is higher, the generalization ability is higher, and the problem of data imbalance can be effectively solved; the problem that two elevators share one external display screen can be solved, and the accuracy of the method is improved.

    本发明公开了一种支持多视角的无标定的电梯运行状态识别方法,所述识别方法包括以下步骤:S1:开启识别后,若设备是由人工携带,则会通过语音提醒使用者将摄像头对准电梯面板;若设备是移动机器人的组件,则会通知机器人转动摄像头朝向电梯面板;S2:以一定的采样频率,控制摄像头拍摄照片或视频,并持续地将单帧图像发送给显示屏识别模型;S3:显示屏识别模型排除广告等的干扰,并输出候选显示屏截图;S4:若没有候选显示屏,则回到步骤1。本发明能够单独识别每个字符,识别准确率更高,泛化能力更强,并能够有效对抗数据不均衡的问题;能解决两部电梯共用一个外部显示屏的问题,提高了方法准确率。
