Embodiment Construction

[0055] The idea, specific structure and technical effects of the present invention will be clearly and completely described below in conjunction with the embodiments and accompanying drawings, so as to fully understand the purpose, scheme and effect of the present invention.

[0056] The technical scheme of the present invention realizes the detection and identification of the elevator inner panel floor buttons and refers to detecting the position of the floor buttons of the elevator in the image containing the elevator inner panel floor buttons and identifying the floor information represented by each floor button (that is, When the button is operated, it corresponds to which floor the elevator moves to). Usually, these floor information will be reflected or imprinted on the surface of the floor button in the form of characters (for example, numbers, letters and characters), Braille, and the like. Therefore, the button recognition in the solution of the present invention is f...

Abstract

The invention relates to an elevator inner panel floor button identification method and a device thereof. The method comprises two processes for detecting and identifying the floor buttons of the inner panel of the elevator, namely a related identification network building and training process; and a detecting and identifying process of floor buttons of the inner panel. In a first process, an open source data set is built and utilized to train a convolutional neural network with a certain structure. In a second process, a candidate area of a text area is provided, then a possible key position is given by using a clustering algorithm, text recognition is performed by using the network trained in the first process, a recognition result is matched with a possible key position result, and a preliminary detection and recognition result is given. The device is a computer device for testing the method. According to the scheme, the operation cost is low, the network does not need to be trained independently for different use environments, the anti-interference capability to noise is high, and the adaptability to different use environments is high.

Description

technical field [0001] The invention relates to a method and a device for detecting and recognizing floor buttons on an elevator inner panel, and belongs to the technical field of image recognition combined with machine vision. Background technique [0002] With the continuous development and maturity of robot technology, they began to gradually appear in public life. At present, mobile robots have been gradually applied in aspects such as autonomous navigation, guidance, and transportation. Mobile service robots that can realize cross-floor navigation in multi-floor buildings have great application value: they can be used in hotels to guide guests or send corresponding items or dishes to designated rooms; In the hospital, it can help doctors or patients with limited mobility to deliver medicines or deliver belongings; it can also be used for building security patrols, indoor cleaning, etc. [0003] At present, the single-floor navigation technology is relatively mature an...
