具体实施方式
为使本发明的目的、技术方案和优点更加清楚明白,下面结合实施方式和附图,对本发明做进一步详细说明。在此,本发明的示意性实施方式及其说明用于解释本发明,但并不作为对本发明的限定。
发明人发现:现有技术中通过对商超内所有的电子价签进行重新定位,发现电子价签位置变化的方案,不仅不能及时地发现价签位置变化,而且对位置不变的价签启动重新定位,也会大大浪费系统的功耗,降低价签的使用寿命。
由于发明人发现以上技术问题,针对商超环境的全场电子价签,提出了一种可以自动检测电子价签位置移动的方法,再对有位置变化的价签进行针对性的重新定位,实时性更高,降低系统功耗,延长电子价签的使用寿命。下面对该检测电子价签位置变化的方案进行详细介绍如下。
图1是本发明实施例中检测电子价签位置变化的方法的流程示意图,如图1所示,该方法包括如下步骤:
步骤101:获取预设货架区域的待检测图像;
步骤102:对所述待检测图像进行处理,根据图像处理结果,确定预设货架区域上发生位置变化的电子价签;
步骤103:将发生位置变化的电子价签信息发送至定位系统;所述定位系统用于对发生位置变化的电子价签进行重新定位。
本发明实施例提供的技术方案通过:获取预设货架区域的待检测图像;对所述待检测图像进行处理,根据图像处理结果,确定预设货架区域上发生位置变化的电子价签;将发生位置变化的电子价签信息发送至定位系统;该定位系统用于对发生位置变化的电子价签进行重新定位,实现了无需对商超内所有的电子价签进行重新定位,即可基于图像分析,检测出发生位置变化的电子价签,并对发生位置变化的电子价签进行针对性地重新定位即可,节省了系统功耗和位置没有变化的电子价签的功耗,延长了电子价签的使用寿命。
下面再结合附图2至图3,对本发明实施例涉及的各个步骤进行详细介绍如下。
第一,首先,如图2和图3所示,在电子价签使用初期,在步骤101之前,可以进行全场电子价签启动定位,获得电子价签的初始图像和初始位置信息,并将预设区域货架的标识与其初始图像关联,形成预设区域货架的标识与初始图像的关系,该关系被存储在数据库中。具体地,上述初始定位的方法可以为:通过系统调度每个价签显示不同的特征,并调度拍照,获取初始图像信息,并通过图像识别,获得每个价签的ID与在图片上的位置关系,并计算出实际坐标位置。
第二,在上述步骤101中,获取预设货架区域的待检测图像的方式可以如图2所示,可以将货架分成若干区域,具体实施时,可以分别对每一区域的货架进行图像采集,每一货架区域也可以设定一个标识,例如区域1、区域2等,或者糖果区、烟酒区等等,每一货架区域包括若干个电子价签,每一电子价签也可以有一价签标识(价签ID),该价签标识为电子价签的编号,一个商品也可能对应多个价签ID。
具体实施时,在上述步骤101中,获取预设货架区域的待检测图像可以在商超任何位置,如图2所示,拍照设备可以放置在货架C的中间位置,便于获取货架D预设区域(例如图2中货架C的第二个大框区域内的模块A发射出的四个箭头对应的区域)内的图像。
第三,再介绍上述步骤102。
(1)首先,介绍用户(例如商超管理人员或客户)想及时了解电子价签位置变化时的具体实施方案。
在一个实施例中,对所述待检测图像进行处理,根据图像处理结果,确定预设货架区域上发生位置变化的电子价签,可以包括:
根据预设货架区域的标识,获取预设货架区域的初始图像;
将待检测图像与初始图像进行比对,得到第一比对结果;
根据所述第一比对结果,确定发生位置变化的电子价签。
具体实施时,首先,可以根据预设货架区域的标识,到预设区域货架的标识与初始图像的关系中去查找,找到预设货架区域的标识对应的初始图像(即预设货架区域的初始图像);其次,将待检测图像与初始图像进行比对,对比图像差异判断价签有无移动的可能,实现了无需对商超内所有的电子价签进行重新定位,即可基于图像分析,检测出发生位置变化的电子价签。
在一个实施例中,将待检测图像与初始图像进行比对,得到第一比对结果,可以包括:
将待检测图像中有价签的局部图片与初始图像中有价签的局部图片进行比对,得到第一比对结果。
具体实施时,将待检测图像与初始图像进行比对,对比可以只对比有价签的位置的局部图片,如果图像有变化,则认为该价签有被移动的可能性。每个价签都要根据待检测图像与初始图像,进行局部的图像对比,遍历每个价签是否有被移动的可能,仅对比有电子价签位置的局部图片,提高了对比的效率,进而提高了检测电子价签位置变化的效率。
(2)其次,再介绍周期性检测电子价签位置变化,便于用户(例如商超管理人员或客户)实时了解电子价签位置变化情况的具体实施方案。
在一个实施例中,获取预设货架区域的待检测图像,可以包括:根据周期性检测命令,获取预设货架区域的当前周期的待检测图像;
对所述待检测图像进行处理,根据图像处理结果,确定预设货架区域上发生位置变化的电子价签,可以包括:
根据预设区域货架的标识,获取预设货架区域的上一检测周期图像;
将当前周期的待检测图像与上一检测周期图像进行比对,得到第二比对结果;
根据所述第二比对结果,确定发生位置变化的电子价签。
具体实施时,在检测到某一电子价签的位置发生变化时,可以更新上述预设区域货架的标识与初始图像的关系,如果该电子价签的位置再发生变化,可以不断的更新该关系,形成预设货架区域的标识与上一检测周期图像的关系。
具体实施时,首先,可以根据预设货架区域的标识,到预设货架区域的标识与上一检测周期图像的关系中去查找,找到预设货架区域的标识对应的上一检测周期图像(即预设货架区域的上一检测周期图像);其次,将当前周期的待检测图像与上一检测周期图像进行比对,对比图像差异判断价签有无移动的可能,实现了无需对商超内所有的电子价签进行重新定位,即可基于图像分析,实时地检测出发生位置变化的电子价签,并对发生位置变化的电子价签进行针对性地重新定位即可,节省了位置没有变化的电子价签的功耗,延长了电子价签的使用寿命,提高了检测电子价签位置变化的效率、准确率以及实时性。
在一个实施例中,将当前周期的待检测图像与上一检测周期图像进行比对,得到第二比对结果,可以包括:
具体实施时,将当前周期的待检测图像中有价签的局部图片与上一检测周期图像中有价签的局部图片进行比对,得到第二比对结果。
将当前周期的待检测图像与上一检测周期图像进行比对,对比可以只对比有价签的位置的局部图片,如果图像有变化,则认为该价签有被移动的可能性。每个价签都要根据当前周期的待检测图像与上一检测周期图像,进行局部的图像对比,遍历每个价签是否有被移动的可能,仅对比有电子价签位置的局部图片,提高了对比的效率,进而提高了实时检测电子价签位置变化的效率。
具体实施时,可以由商超内的定位系统或定位服务器发来周期性检测命令,该方案实现了根据周期性检测命令,自动实时地检测价签位置移动(变化)。该方案进一步提高了检测电子价签位置变化的效率和实时性。
在一个实施例中,所述检测电子价签位置变化的方法被应用在商超内的任一电子价签上。
具体实施时,如图2所示,该检测电子价签位置变化的方法被应用在商超内的任一电子价签上,例如图2中的货架C的第二个大框区域内的模块A为一个电子价签,该电子价签除了具备普通电子价签的功能,还集成了本发明实例提供检测电子价签位置变化的方法的功能,扩展了电子价签的功能类型。当然,该检测电子价签位置变化的方法也 可以被应用一个独立的模块A上,即该模块A是一个单独的设备,被设置在图2中的货架C的所示的位置上。
具体实施时,图2中的上述模块A可以为无线拍照设备,该设备集成了无线模块、拍照模块、算法处理模块,其中:拍照模块用于对对面货架进行拍照(例如可以实现获取预设货架区域的图像),算法模块处理照片用于发现有无价签位置变化(例如可以实现对所述图像进行处理,根据图像处理结果,确定预设货架区域上发生位置变化的电子价签),无线模块将发生位置变化需要重新定位的信息上传给定位系统(即可以实现将发生位置变化的电子价签信息发送至定位系统)。
具体实施时,图2中的上述模块B可以是电子价签,如果商品价签有位置变化,模块A可以通过拍照并算法处理分析出价签存在的位置变化。
再结合图2和图3举一实例,以说明本发明如何实施。
如图3所示,检测价签位置移动的方法可以包括如下几个步骤:
1.全场价签启动定位,获得价签初始位置信息(详见上述实施例的介绍);
2.模块A周期性启动对对面货架拍照,并利用图像处理算法判断对面货架上的价签有无位置变化,并将位置变化的价签通过无线上报定位服务器;
3.定位服务器若收到价签有位置变化,则启动对位置变化价签的重定位。
基于同一发明构思,本发明实施例中还提供了一种检测电子价签位置变化的装置,如下面的实施例。由于检测电子价签位置变化的装置解决问题的原理与上述检测电子价签位置变化的方法相似,因此检测电子价签位置变化的装置的实施可以参考上述检测电子价签位置变化的方法的实施,重复之处不再赘述。以下所使用的,术语“模块”或者“单元”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现,但是硬件,或者软件和硬件的组合的实现也是可能并被构想的。
