Description

基于多传感器的距离与身高的确定方法及其装置 技术领域
本公开涉及安检领域,并且更具体地涉及一种基于多传感器的距离与身高的确定方法、一种电子设备以及一种计算机可读存储介质。
背景技术
长期以来,在毒品缉查工作中,排查嫌疑人员是否吸毒的常规检验方法有尿液、血液或者唾液检验。但是,由于以上检验必须经历在监督下取样等诸多环节,往往要耗费大量的时间及人力、物力,并且检验结果也容易受到干扰而出现假阴性、假阳性等问题。再加之毒品品种繁多,需要逐一用尿检试纸排查会加大尿检试纸的使用量、增加成本,因此并不适用于广泛筛查。此外,近年来部份吸毒人员采取特殊方法中和自己体内的毒品代谢,使常规尿检失去作用,查辑人员只能采用气相色普、气质联用等准确的检测方法,用这些方法虽然准确,但检测时间需要2-3天,且成本很高。
为了解决这些显而易见的弊端和对吸毒人员检测中存在的诸多问题,需要一种安全、操作简单、远距离无感采集行人瞳孔图像并通过对图像进行分析来判别是否有吸毒嫌疑的产品。
而实现远距离对准用户的人脸、采集眼睛图像、对眼睛的瞳孔进行分割并进行瞳孔尺寸的计算的基础是,需要确定用户与安检仪器的距离以及用户的身高。
目前基于视频图像处理的远距离瞳孔大小估算方法还不成熟,尤其是测距不准,特别是在被测人员身高(1.5米到2.1米)波动较大的情况下。因此,如何准确确定出被测人员的身高、被测人员与安检设备之间的距离,是一个需要解决的技术难题。

为了解决如背景技术部分中所阐述的问题,本公开的实施例提供了一种用于基于瞳孔图像确定被测对象是否吸毒的基于多传感器的距 离与身高的确定方法和装置,所述方法包括:利用位于安检装置上的第一传感器、第二传感器和第三传感器,分别测量被测对象距离其的第一距离、第二距离和第三距离,并且测量所述被测对象的第一身高、第二身高和第三身高;利用第一确定单元分别确定所述第一距离、所述第二距离和所述第三距离中的每一个距离与最小距离阈值和最大距离阈值的大小关系;利用第二确定单元,基于所确定的第一距离、第二距离和第三距离中的每一个距离与最小距离阈值和最大距离阈值的大小关系,确定被测对象距离安检装置的最终距离和被测对象的最终身高;以及根据所确定的最终距离和最终身高,对被测对象的瞳孔图像进行像素和尺寸转换,以确定被测对象是否吸毒。
以下将参考附图并结合具体实施例详细阐述本公开。
图1示意性地示出了根据本公开实施例的基于多传感器的距离与身高的确定方法的系统架构。在系统架构100为对吸毒人员进行检测的总架构,在其中安检机上设置有远距离红外瞳孔采集设备,其对被测人员的瞳孔进行识别与检测。在得到被测人员的瞳孔图像之后,基于被测人员身高以及被测人员到安检装置的距离来对瞳孔图像进行像素与尺寸转换,之后基于转换后的瞳孔图像确定被测人员是否为吸毒人员。
因此,本申请提供的基于多传感器的距离与身高的确定方法及其装置对于确认被测人员是否吸毒来说至关重要。
图2示意性地示出了根据本公开实施例的多个传感器的示例布置方式。
如图2所示,第一传感器布置在距离地面a米的高度处,第二传感器布置在距离地面b米的高度处,第三传感器布置在距离地面c米的高度处。
在地面上还设置有两个参考点,即近距点A和远距点B。其中,近距点A为传感器的检测能力下的被测人员与传感器的最近距离,并且远距点B为传感器的检测能力下对的被测人员与传感器的最远距离。
在本文中,将近距点A到安检装置(图2中的o点)的距离设置为最小距离阈值,将远距点B到安检装置(图2中的o点)的距离设 置为最大距离阈值,以用于在下文描述的处理中。
在示例性实施例中,第一传感器、第二传感器和第三传感器可以是相同的传感器,或者可以是不同的传感器。
在第一传感器、第二传感器和第三传感器是相同的传感器的情况下,示例性地,当传感器的检测能力为300cm至400cm时,最小距离阈值为280cm,并且最大距离阈值为420cm。
由于在安检时人流通常是连续通过安检机的,因此,可能会出现多个被测人员前后紧贴通过安检装置的情况。
鉴于此情况,出于使得被测结果更准确的目的,本申请中还设置了预定被测人员间隔距离。
优选地,预定被测人员间隔距离可以被设置为20cm。

在本文中,被测对象距离安检装置的最终距离和最终身高可以被定义为基于第一传感器、第二传感器和第三传感器各自测量的距离和身高而确定出的针对被测人员的最佳的距离和身高。
第二确定单元可以被配置为设置在安检装置中。
备选地,第二确定单元可以被配置为设置在与安检装置有线或无线连接的另一处理设备中。
