附图说明
后文将参照附图以示例性而非限制性的方式详细描述本发明的一些具体实施例。附图中相同的附图标记标示了相同或类似的部件或部分。本领域技术人员应该理解,这些附图未必是按比例绘制的。附图中:
图1为本发明一具体实施方式中冰箱的控制方法的步骤流程图;
图2为本发明一具体实施方式中冰箱制冷间室内摄像头的安装结构示意图;
图3为本发明一具体实施方式中冰箱的俯视图。
具体实施方式
下面结合附图所示的各实施方式对本发明进行详细说明,但应当说明的是,这些实施方式并非对本发明的限制,本领域普通技术人员根据这些实施方式所作的功能、方法、或者结构上的等效变换或替代,均属于本发明的保护范围之内。
参图1至图3所示,介绍本发明冰箱控制方法的一较佳实施方式。首先,冰箱10包括:制冷间室11;封闭制冷间室11的门体12;摄像头13,用于拍摄制冷间室11和门体12内的图像;控制器(图未示);传感器(图未示),用于感测门体12的打开角度,且传感器与控制器电性连接。
摄像头13活动地设置在制冷间室11的内侧壁上部。详细地,在制冷间室11的内侧壁上部设有滑轨组件,该滑轨组件包括固定在制冷间室11内的弧形轨道141和沿弧形轨道141滑动的滑轨142,摄像头13固定安装在滑轨142上,可随滑轨142移动。在本发明中,使用驱动电机(图未示)驱动滑轨142沿弧形轨道141滑动,其中,驱动电机电性连接冰箱的控制器,控制器被设置为根据传感器反馈的信号控制驱动电机正转或反转,以使得滑轨142沿弧形轨道141可来回滑动。优选地,控制器可以是包括微控制器(Micro Controller Unit,MCU)的集成电路。本领域技术人员所熟知的是,微控制器可以包括中央处理单元(Central Processing Unit,CPU)、只读存储模块(Read-Only Memory,ROM)、随机存储模块(Random Access Memory,RAM)、定时模块、数字模拟转换模块(A/D Converter)、以及若干输入/输出端口。当然,控制装置也可以采用其它形式的集成电路,如特定用途集成电路(Application Specific Integrated Circuits,ASIC)或现场可编程门阵列(Field-programmable Gate Array,FPGA)等。
在本实施方式中,该冰箱的控制方法具体包括:
S1、获取到有人靠近并欲打开冰箱门体的信号,控制摄像头从初始位置移动至第一位置。在冰箱门体12上设有人体感应器(图未示),人体感应器发送信号给控制器,控制器获取到有人靠近并欲打开冰箱门体的信号,并根据人体感应器反馈的信号控制驱动电机正转,以使得摄像头13随着滑轨142从初始位置沿弧形轨道141顺时针移动到第一位置,第一位置与初始位置所成的夹角γ角度为55°。
S2、获取到门体从关闭状态转变为打开状态的信号,控制摄像头从第一位置逐渐向第二位置移动。在本发明中,门体的打开角度α是通过传感器感测的,传感器电性连接冰箱的控制器,控制器被设置为根据传感器反馈的信号控制控制驱动电机正转或反转,即控制摄像头的移动路径。当传感器感测到门体的打开角度α逐渐增大时,反馈信号给控制器,控制器 判断门体从关闭状态转变为打开状态的信号,并控制驱动电机反转,使得摄像头13逆时针转动,从第一位置逐渐向第二位置移动。其中,第二位置位于初始位置和第一位置之间,第二位置与所述初始位置所成的夹角γ角度为30°。
S3、获取门体的打开角度,比较门体的打开角度和临界角度,当门体的打开角度α小于临界角度时,摄像头拍摄门体内部图像。当传感器感测到门体的打开角度α后,反馈打开角度的信号给控制器,控制器将打开角度α与临界角度相比较,当门体的打开角度α小于临界角度时,摄像头拍摄门体内部图像;当门体的打开角度α大于临界角度时,限制摄像头拍摄门体内部图像。这是因为门体的打开角度α过大,拍摄有延迟,有可能会拍摄的用户的头部或手部,造成照片废品率较高。优选地,临界角度为50°。
参图3及表1所示,通过大数据统计,在用户开门的10-45°时,摄像头拍照可以拍到门体最边缘,假设的理论数据可以得出如下:其中,摄像头的广角为(125度)

表1
S4、获取到门体从打开状态转变为关闭状态的信号或者获取到当门体的打开角度逐渐减小的信号,控制摄像头逐渐向第一位置移动,且拍摄门体内部图像。当传感器感测到门体的打开角度α逐渐减小时,反馈信号给控制器,控制器判断门体12从打开状态转变为关闭状态的信号,控制驱动电机正转,使得摄像头13顺时针转动,逐渐向第一位置移动,且拍摄门体12内部图像。当门体的打开角度α大于临界角度关门时,摄像头13逐渐向第一位置移动,且限制摄像头拍摄门体12内部图像;当门体的打开角度α小于临界角度关门时,摄像头13逐渐向第一位置移动,摄像头13拍摄门体12内部图像,并进行先后对比,确认门体内取放的食材。
S5、获取到门体的关闭信号,控制摄像头回归到初始位置,且拍摄制冷间室内的图像。 当传感器感测到门体关闭时,反馈信号给控制器,经过一设定的时间段后,摄像头13回归到初始位置,并拍摄制冷间室内的图像,并进行先后对比,确认制冷间室内取放的食材,从而实现只用一个摄像头即可拍摄冷间室和门体内的图像,成本低。
这里需要说明的是,摄像头拍摄的图像进行图像分割、图像模式识别以确定食物信息,所述食物信息包括食物的名称、存放位置。
对于本领域技术人员而言,显然本发明不限于上述示范性实施例的细节,而且在不背离本发明的精神或基本特征的情况下,能够以其他的具体形式实现本发明。因此,无论从哪一点来看,均应将实施例看作是示范性的,而且是非限制性的,本发明的范围由所附权利要求而不是上述说明限定,因此旨在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本发明内。不应将权利要求中的任何附图标记视为限制所涉及的权利要求。
此外,应当理解,虽然本说明书按照实施方式加以描述,但并非每个实施方式仅包含一个独立的技术方案,说明书的这种叙述方式仅仅是为清楚起见,本领域技术人员应当将说明书作为一个整体,各实施例中的技术方案也可以经适当组合,形成本领域技术人员可以理解的其他实施方式。
