具体实施方式
下面将结合附图和具体实施例对本发明技术方案进行清楚、完整地描述,显然,这里所描述的实施例仅仅是发明的一部分实施例,而不是全部的实施例。基于本发明描述的具体实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都应当属于本发明权利要求所限定的保护范围内。
实施例1
请参阅图1-2,图1为本发明实施例提供的一种扫地机器人的结构示意图;图2为图1中的一种扫地机器人的模块示意图。
本实施例中的扫地机器人1包括控制系统150、驱动系统120、清洁系统130、传感器系统160、电源系统170、双目摄像头110(双目摄像头110为图像传感器,在本实施例中包括左CCD摄像头11、右CCD摄像头12)和图像处理系统140。在对环境较为简单的情况下,出于成本和速度考虑,也可以将CCD(英文单词为Charge coupled Device,即电荷耦合元件)用CMOS(Compementary Metal Oxide Semiconductor,即互补金属氧化物半导体)代替。
控制系统150包括存储有扫地机器人1工作程序的MCU或单片机(本实 施例中为带有存储器的MCU),所述控制系统150根据障碍物信息执行不同的动作;即根据传感器系统160或图像处理系统140返回的障碍物信息控制驱动系统120及清洁系统130工作;双目摄像头110用于在同一时刻获取同一障碍物的不同角度的两幅图片信息;图像处理系统140用于对双目摄像头110获取的两幅图片信息进行处理并得到障碍物信息;驱动系统120包括左右驱动轮,用于驱动扫地机器人1在工作区域运动;清洁系统130包括中扫、真空吸尘装置、边扫及尘盒,用于清扫地面垃圾并存储至尘盒;传感器系统160包括地检和墙检,分别用于检测工作区域表面落差及周围障碍物(包括墙);电源系统170用于为扫地机器人1的各系统提供电能,一般为可充电电池(如锂电池)。
障碍物信息包括障碍物大小、障碍物形状以及障碍物与扫地机器人1的距离
双目摄像头110包括左CCD摄像头11和右CCD摄像头12,左右摄像头相对固定安装,位于扫地机器人1主体的前侧方,左CCD摄像头11和右CCD摄像头12大致位于同一水平面上(与标定模型算法有关,本实施例为Opencv,需要在物理结构上保证双摄像头的光轴平行),在同一时刻左右摄像头分别获取其前进方向水平范围150°至180°、竖直方向90°至120°范围内的障碍物的不同角度的两幅图片。双目摄像头110的左CCD摄像头11和右CCD摄像头12在扫地机器人1出厂前进行立体标定,左CCD摄像头11和右CCD摄像头12之间的的旋转矩阵R和平移矩阵t可以由张正友标定法求得。其中双目摄像头110可以为图像传感器。
本实施例中,障碍物的距离及大小的识别过程如下:
本实施例基于Opencv平台,使用Opencv提供的SGBM算法进行匹配计算。 首先对左右CCD摄像头在同一时刻拍摄的图片进行立体匹配,然后对原始图片进行二值化处理、高斯模糊、canny算子轮廓检测,寻找障碍物轮廓并用最小四边形将障碍物完整框出,通过计算四边形的四个顶点坐标得到障碍物的像素大小;通过计算四边形四个顶点的坐标得到物体中心点的像素坐标,通过双目测距原理得到障碍物中心点距离摄像头的距离,根据三角形原理,可以计算出障碍物的宽度和高度,实现对障碍物大小的测量。
具体地,首先使用reprojectImageTo3D生成三维点云,使用findContours获得障碍物轮廓,遍历删除最大及最小轮廓,使用minAreaRect获得轮廓的最小举证并得到矩形四个顶点的坐标,然后通过三角函数计算出障碍物的大小(长宽高等数据)。
在本实施例中,控制器(带有存储器的MCU)存储的程序与室内环境的常见静态物体(如家具、家电或门槛等)及动态物体(如人或宠物)相关,即将室内环境的各物体(障碍物)与对应的工作模式关联起来,在识别到不同障碍物时执行不同动作,比如:识别到门槛、拖鞋或线缆等高度较低的物体时(可通过设定高度阈值,如扫地机器人1目前的爬坡高度为2cm左右,在障碍物高度大于2cm时,将障碍物标认为是不可跨域的,在扫地机器人1移动至该障碍物附近时,不再对该障碍物进行跨越尝试,而直接执行回避动作),扫地机器人1移动至障碍物附近时增大驱动系统120的驱动力并执行跨越动作;识别到障碍物为毛毯时,执行跨越动作的同时增加清洁系统130的吸力及驱动系统120的驱动力;识别到障碍物为垃圾时,扫地机器人1驶向垃圾并清扫;识别到障碍物为人或冰箱等高度较高的物体时,扫地机器人1执行回避该动作等。该设置可以使扫地机器人1工作更为智能化,同时提升了用户体验。
实施例2
请参阅图3-6,图3为本发明实施例提供的另一种扫地机器人的模块示意图;图4为本发明实施例提供的一种图像处理终端的模块示意图;图5为本发明实施例提供的一种扫地机器人系统的模块示意图;图6为本发明实施例提供的一种扫地机器人系统的结构示意图。
如图3所示,本实施中的扫地机器人1包括控制系统150、驱动系统120、清洁系统130、传感器系统160、电源系统170、双目摄像头110(双目摄像头110为图像传感器,在本实施例中包括左CCD摄像头11、右CCD摄像头12)和无线通信系统。在对环境较为简单的情况下,出于成本和速度考虑,也可以将CCD(英文单词为Charge coupled Device,即电荷耦合元件)用CMOS(Compementary Metal Oxide Semiconductor,即互补金属氧化物半导体)代替。
本实施例中的扫地机器人1与实施例1中的基本相同,不同的地方在于:A、本实施例中的扫地机器人1没有图像处理系统140;B、本实施例中的扫地机器人1将双目摄像头110获取的两幅图片信息通过无线通信模块180(如WIFI模块或Zigbee模块)发送至图像处理终端2进行对两幅图像信息的处理。
本实施例中的扫地机器人1与第一实施例中的扫地机器人1的控制系统150、驱动系统120、清洁系统130、传感器系统160、电源系统170、双目摄像头110的功能以及作用相同,本实施例不在赘述,详细参见实施例1。
无线通信模块180用于将两幅所述图片信息向外部传输,还用于接收外部传输的障碍物信息,将障碍物信息传输至控制系统150,以便控制系统150根据障碍物信息执行不同的动作;即根据传感器系统160或图像处理系统210 返回的障碍物信息控制驱动系统120及清洁系统130工作。
如图4所示,本实施例中的图像处理终端2为云服务器(也可为其他具备双目摄像头110图像处理能力的PC平台或嵌入式平台),包括图像处理系统210和无线通信模块220;云服务器与扫地机器人1之间的无线连接网络包括4G、WIFI网络等,组网的方式包括AP模式(无线接入点)或STA模式(STA站点)。
本实施例中的障碍物的距离及大小的识别过程与实施例1中相同,本实施例不在赘述,详细参见实施例1。
如图5-6所示,本实施例中的障碍物识别过程如下:扫地机器人1的双目摄像头110同一时刻获取同一障碍物的不同角度的两幅图片信息,并通过扫地机器人1的无线通信模块180将两幅图片信息传输至图像处理终端2的无线通信模块220,图像处理终端2的图像处理系统210对两幅图片信息进行处理得到障碍物信息,并通过图像处理终端2的无线通信模块220将障碍物信息传输至扫地机器人1的无线通信模块180,扫地机器人1的控制系统150基于障碍物信息控制驱动系统120及清洁系统130工作。其中两幅图片信息以及障碍物信息可通过英特网(internet)进行传输。图像处理终端优选的为云服务器。
实施例3
请参阅图7,图7为本发明实施例提供的一种扫地机器人的工作方法的流程图。
如图7所示,本实施例中一种扫地机器人的工作方法包括以下步骤S100至S400:
步骤S100:将所有障碍物信息与对应的工作模式相关联。
具体的,指将扫地机器人所在的室内环境常见的障碍物的形状、颜色等特征信息与对应的工作模式关联起来,扫地机器人的控制器根据反馈的障碍物信息选择不同的工作模式。比如,符合垃圾特征时,扫地机器人驶向障碍物,同时增大清洁系统的吸力或滚刷转速;符合地毯特征时,增大驱动系统的驱动力的同时增大清洁系统的吸力或滚刷转速;如符合水滞特征时,执行回避动作。
步骤S200:在同一时刻获取同一障碍物的不同角度的两幅图片信息。
具体的,扫地机器人的前进方向的前侧面的大致位于同一高度安装双目摄像头(左CCD摄像头11和右CCD摄像头12),在同一时刻左右摄像头分别获取其前进方向水平范围150°至180°、竖直方向90°至120°范围内的障碍物的不同角度的两幅图片。
步骤S300:基于两幅所述图片信息得到障碍物信息。
具体的,将获取的两幅图片发送至图像处理系统进行处理后(处理过程参考实施例1中的描述),得到包括障碍物大小、障碍物形状、与扫地机器人的距离等障碍物信息,然后将该障碍物信息发送至扫地机器人的控制系统。如实施例1、实施例2中所描述,图像处理系统可为安装在扫地机器人上或云服务器上。
步骤S400:基于所述障碍物信息选择不同的工作模式。
具体的,可以判断障碍物的高度是否大于预设值时,如果是则扫地机器人在移动至该障碍物附近时执行回避动作,如果否则扫地机器人继续沿原方向运动。即当所述障碍物信息的障碍物大小不大于预设值时,所述控制系统控制驱动系统增大驱动力,使扫地机器人越过障碍物;当所述障碍物信息的障碍物大小大于预设值时,所述控制系统控制驱动系统,使扫地机器人沿障 碍物轮廓绕过障碍物。还可以判断障碍物是否存在可供扫地机器人穿过的空间,如果是则扫地机器人继续沿原方向运动,如果否则扫地机器人在移动至该障碍物附近后执行回避动作。具体地,通过障碍物形状判断其是否有供扫地机器人穿过的空间,再判断盖空间的高度和宽度是否大于扫地机器人的高度和宽度,在高度和宽度同时满足的条件下认为该空间可供扫地机器人穿过。还可以当基于所述障碍物信息判断当前障碍物为毛毯时,所述控制系统控制驱动系统增大驱动力,使扫地机器人越过毛毯;并控制所述清洁系统增大清洁功率;当基于所述障碍物信息判断当前障碍物为垃圾时,所述所述控制系统控制驱动系统,使扫地机器人向垃圾运动;并控制所述清洁系统进行清洁。障碍物信息包括障碍物大小、障碍物形状以及障碍物与扫地机器人的距离。
以上所述实施例的各技术特征可以进行任意的组合,为使描述简洁,未对上述实施例中的各个技术特征所有可能的组合都进行描述,然而,只要这些技术特征的组合不存在矛盾,都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式,其描述较为具体和详细,但并不能因此而理解为对发明专利范围的限制。应当指出的是,对于本领域的普通技术人员来说,在不脱离本发明构思的前提下,还可以做出若干变形和改进,这些都属于本发明的保护范围。因此,本发明专利的保护范围应以所附权利要求为准。
