移动机器人10的规划路径为规划的该移动机器人10在预设时间段内的移动路径,或者为规划的该移动机器人10移动预设长度对应的移动路径。
比如,预设时间段为5秒,则移动机器人10的规划路径为5秒内移动机器人10的移动路径。
又比如,预设长度为1米,则移动机器人10的规划路径为移动机器人10移动1米对应的移动路径。
可选的,移动机器人10根据移动障碍物的第一位置、移动障碍物的规划路径、静止障碍物的第二位置、移动障碍物的手势信息中的至少一种感知数据,通过第一预设策略确定移动机器人10的规划路径,根据移动机器人10的规划路径生成路径提示信息。其中,第一预设策略可参考下面实施例中的相关描述, 在此暂不介绍。
步骤203,将路径提示信息投影显示在目标投影面上。
其中,目标投影面为用于投影显示路径提示信息的投影面,比如,目标投影面为地面或者墙面。
目标投影面可以是预设的,也可以是根据采集得到的感知数据,通过第二预设策略动态确定的投影面。示意性的,第二预设策略包括若感知数据中静止障碍物的第二位置与移动机器人10的当前位置之间的距离大于或者等于第一预设阈值,则确定目标投影面为地面;若感知数据中静止障碍物的第二位置与移动机器人10的当前位置之间的距离小于第一预设阈值,且该移动机器人10的当前位置的预设范围内存在类型为墙面的静止障碍物,则确定目标投影面为墙面。本实施例对第二预设策略不加以限定。下面仅以目标投影面为地面为例进行说明。

第二种可能的投影形式:移动机器人10将路径提示信息以图像投影形式,投影显示在目标投影面上。
可选的,移动机器人10将路径提示信息以预设图像的形式进行投影显示,预设图像包括菱形图像、矩形图像、圆形图像或者不规则多边形图像等等,本实施例对此不加以限定。
可选的,移动机器人10根据目标投影面的平面颜色确定路径提示信息的投影颜色,将路径提示信息以该投影颜色的形式投影显示在目标投影面上。其中,投影颜色不同于平面颜色。
为了避免路径提示信息的投影颜色与目标投影面的平面颜色一致或者相似,导致信息显示效果较差的问题,移动机器人10获取感知数据中目标投影面的平面颜色,确定与平面颜色不同的投影颜色,且平面颜色与投影颜色的颜色区分度高于预定区分阈值,将路径提示信息以投影颜色的形式投影显示在目标投影面上。
可选的,平面颜色与投影颜色的颜色区分度为平面颜色与投影颜色之间色相、饱和度和明度中至少一种的差异程度。
可选的,移动机器人10中预先存储有平面颜色和投影颜色的对应关系。示意性的,该对应关系如表一所示。其中,平面颜色“黄色”对应投影颜色“蓝色”,平面颜色“绿色”对应投影颜色“红色”,平面颜色“白色”对应投影颜色“棕色”。
表一

比如,基于表一所提供的对应关系,移动机器人10获取到的感知数据中地面的平面颜色为蓝色,则移动机器人10从存储的对应关系中查找与平面颜色“黄色”对应的投影颜色“蓝色”,将路径提示信息以蓝色图案的形式投影显示在目标投影面上。
第三种可能的投影形式:移动机器人10将路径提示信息以动画投影形式,投影显示在目标投影面上。
可选的,移动机器人10将路径提示信息以动画导向箭头的形式,投影显示在目标投影面上。其中,动画导向箭头用于指示该移动机器人10的移动方向。
在一个示意性的例子中,如图5所示。移动机器人10沿正东方向移动,行人43沿正西方向移动,当移动机器人10获取感知数据,该感知数据包括行人43的第一位置时,移动机器人10根据感知数据确定路径规划信息44,将移动机器人10的宽度作为投影边界,将路径提示信息44以动画导向箭头的形式投影显示在地面上,用于向行人43提示该移动机器人10的规划路径。
需要说明的是,移动机器人10除了可以将路径提示信息以动画导向箭头的形式进行投影显示,还可以将路径提示信息以其他的预设动画的形式投影显示在目标投影面上,本实施例对此不加以限定。下面仅以将路径提示信息以动画导向箭头的形式进行投影显示为例进行说明。
第四种可能的投影形式:移动机器人10将路径提示信息以视频投影方式,投影显示在目标投影面上。
由于路径提示信息通常是动态变化的,因此,移动机器人10可以在目标投影面上投影显示动态视频,该动态视频用于提示该移动机器人10的规划路径。
可选的,移动机器人10预先设置该动态视频的视频尺寸和/或分辨率。
需要说明的是,上述四种可能的投影形式中可以任意两种两两结合实施,或者,或者上述四种可能的投影形式中可以任意三种结合实施,上述四种可能的投影形式全部结合实施,此乃本领域技术人员根据上述各个投影形式所易于思及的,本申请实施例不对这几种投影形式结合实施的方式一一重复赘述。
在将路径提示信息投影显示在目标投影面上之前,移动机器人10根据障 碍物的位置确定目标投影面上的投影区域,投影区域与障碍物的位置不存在重叠区域。在确定出投影区域之后,移动机器人10将路径提示信息投影显示在投影区域上。
可选的,移动机器人10将路径提示信息以上述任意一种或者几种投影形式投影显示在目标投影面的投影区域上。
为了避免将路径提示信息投影到障碍物的位置上,导致信息显示效果较差的问题,移动机器人10获取感知数据中障碍物的位置,从而在目标投影面上确定与障碍物的位置不存在重叠区域的投影区域。
在一个示意性的例子中,如图6所示,移动机器人10沿正东方向移动,行人52沿正西方向移动,行人53沿正南方向移动,当移动机器人10获取感知数据,该感知数据包括行人52的第一位置和行人53的第一位置时,移动机器人10根据感知数据确定路径规划信息53,确定与行人52的第一位置和行人53的第一位置均不存在重叠区域的投影区域,将路径提示信息54投影显示在投影区域上。
可选的,投影区域的宽度大于或等于移动机器人10的宽度。
综上所述,本实施例通过移动机器人获取用于指示移动机器人在行进过程中的周围环境的感知数据,根据感知数据确定移动机器人的规划路径,将包括移动机器人的规划路径的路径提示信息投影显示在目标投影面上;使得移动机器人在行进过程中能够在目标投影面上投影显示出将要移动的规划路径,进而使得附近的行人能够直接在目标投影面上看到该移动机器人将要移动的规划路径,避免了相关技术中由于语音形式而导致的诸多限制,有利于移动机器人快速且精确对行人进行信息提示。
本实施例还通过将路径提示信息以第一投影形式投影显示在目标投影面上,第一投影形式包括文本投影形式、图像投影形式、动画投影形式和视频投影方式中的至少一种,使得路径提示信息的投影形式多样化,提高了路径提示信息的信息显示效果。
为了显示更多与移动机器人10在移动过程中的信息,该提示信息除了包括路径提示信息,还可以包括辅助提示信息,辅助提示信息包括:移动机器人10的预计到达时间和/或移动速度。下文以示意性的实施例介绍基于路径提示信息和辅助提示信息的交互方法。

步骤601,获取感知数据,感知数据用于指示移动机器人10在行进过程中的周围环境。
以感知组件包括摄像头为例,移动机器人10获取摄像头拍摄的第i帧图像帧,根据第i帧图像帧确定第i帧图像帧对应的感知数据。其中,该摄像头以预定的拍摄速率进行拍摄,如:24fps(即,每秒24帧),i为自然数。
感知数据包括:移动障碍物的第一位置、移动障碍物的规划路径、移动障碍物的手势信息、静止障碍物的第二位置、静止障碍物的类型、移动机器人10的当前位置和目标投影面的平面颜色中的至少一种。
可选的,移动障碍物的第一位置、静止障碍物的第二位置、静止障碍物的类型、目标投影面的平面颜色均是采用第一获取策略得到的,移动障碍物的规划路径是采用第二获取策略得到的,移动障碍物的手势信息是采用第三获取策略得到的。下面,依次介绍这三种获取策略。
第一种获取策略包括:移动机器人10根据第i帧图像帧,采用机器学习算法计算得到图像特征,根据计算得到的图像特征确定感知数据。
移动机器人10采用机器学习算法计算得到图像特征包括但不限于以下两种可能的实现方式:
在一种可能的实现方式中,机器学习算法为传统机器学习算法,移动机器人10通过传统机器学习算法计算得到第i帧图像帧的图像特征。
比如,传统机器学习算法为基于方向梯度直方图(Histogram of Oriented Gradient,HOG)特征和支持向量机(Support Vector Machine,SVM)模型的目标检测算法。
在另一种可能的实现方式中,机器学习算法为神经网络算法,移动机器人10将第i帧图像帧输入至深度网络,通过深度网络提取第i帧图像帧的图像特征。其中,深度网络是用于对输入的图像帧进行特征提取后,得到图像帧的图像特征的神经网络。
可选的,深度网络包括卷积神经网络(Convolutional Neural Network,CNN)模型、深度神经网络(Deep Neural Network,DNN)模型、循环神经网络(Recurrent Neural Networks,RNN)模型、嵌入(embedding)模型、梯度提 升决策树(Gradient Boosting Decision Tree,GBDT)模型、逻辑回归(Logistic Regression,LR)模型中的至少一种。比如,深度网络为基于区域的卷积神经网络(Region-based Convolutional Neural Networks,RCNN)。
移动机器人10根据计算得到的图像特征确定感知数据包括:根据计算得到的图像特征和预先标定的摄像头参数估算得到移动障碍物的第一位置、静止障碍物的第二位置、静止障碍物的类型、目标投影面的平面颜色中的至少一种感知数据。
比如,以移动障碍物为行人为例,移动机器人10通过深度网络提取第i帧图像帧的图像特征包括该行人的双脚位置和/或人体尺寸等,根据提取得到的图像特征和预先标定的摄像头参数估算得到行人与该移动机器人10的距离,从而得到该行人的第一位置。

第三获取策略包括:移动机器人10根据采集到的第i帧图像帧,采用机器学习算法检测移动障碍物的手势动作,当检测到的手势动作与存储的手势动作相匹配时,确定与该检测到的手势动作对应的手势信息。
可选的,移动机器人10中预先存储有手势动作和手势信息的对应关系。示意性的,该对应关系如表二所示。其中,当手势动作为第一预设动作,即五根手指均不弯曲,且掌心面对移动机器人10时,对应的手势信息为用于指示移动机器人10停止的信息;当手势动作为第二预设动作,即拇指朝上,且除拇指以外的其他四根手指向手心方向完全弯曲时,对应的手势信息为用于指示移动机器人10让行的信息;当手势动作为第三预设动作,即食指朝向指定方向,且除食指以外的其他四根手指向手心方向完全弯曲时,对应的手势信息为用于指示移动机器人10向指定方向移动的信息。
表二
手势动作 手势信息
第一预设动作 停止
第二预设动作 让行
第三预设动作 向指定方向移动
基于表二所提供的对应关系,在一个示意性的例子中,以移动障碍物为行人为例,移动机器人10根据采集到的第i帧图像帧,采用机器学习算法检测得到行人的手势动作,将检测得到的手势动作与存储的手势动作依次进行比较,当检测得到的手势动作与第一预设动作相匹配时,确定与该检测到的手势动作对应的手势信息用于指示移动机器人10停止。
步骤602,根据感知数据确定路径提示信息和辅助提示信息,辅助提示信息包括移动机器人10的预计到达时间和/或移动速度。
移动机器人10根据移动障碍物的规划路径、静止障碍物的第二位置、移动障碍物的手势信息中的至少一种感知数据,通过预设规则确定移动机器人10的规划路径,根据移动机器人10的规划路径生成路径提示信息。路径提示信息的确定过程可参考上述实施例中的相关细节,在此不再赘述。
可选的,当移动障碍物的手势信息包括至少两个移动障碍物各自对应的手势信息时,比较至少两个移动障碍物各自与移动机器人10之间的距离,将距离最近的移动障碍物的手势信息确定为目标手势信息,根据目标手势信息生成路径提示信息。
在一个示意性的例子中,基于表二所提供的对应关系,以移动障碍物为行人为例,移动机器人10根据采集到的第i帧图像帧,采用机器学习算法检测得到两个行人(分别为行人A和行人B)的手势动作,其中行人A的手势动作为第三预设动作,行人B的手势动作为第一预设动作,且行人A与移动机器人10的距离小于行人B与移动机器人10的距离,因此移动机器人10将行人A的第三预设动作对应的手势信息确定为目标手势信息,根据目标手势信息所指示的指定方向,确定移动机器人10的路径提示信息。
可选的,移动机器人10将移动机器人10的预计到达时间和/或移动速度确定为辅助提示信息。
其中,移动机器人10的移动速度可以是预设的,也可以是动态确定得到的。移动速度可以是匀速的,也可以是变速的。下面仅以移动机器人10的移动速度是动态确定的恒定速度为例进行说明。
辅助提示信息包括移动机器人10的预计到达时间,移动机器人10根据感知数据确定辅助提示信息的方式包括:根据移动机器人10的规划路径和移动机器人10的移动速度确定移动机器人10的预计到达时间。
比如,移动机器人10的规划路径为以该移动机器人10的当前位置为起点 移动长度为3米的路径,移动机器人10的移动速度为1米/秒,则确定该移动机器人10在该规划路径上移动时到达目标位置的时间为3秒,目标位置为规划路径的终点。
辅助提示信息包括移动机器人10的移动速度,移动机器人10根据感知数据确定辅助提示信息的方式包括:移动机器人10根据移动障碍物的规划路径和移动机器人10的规划路径通过预设规则确定移动机器人10的移动速度。
比如,移动机器人10根据移动障碍物的规划路径和移动机器人10的规划路径,通过预设规则确定移动机器人10的移动速度为1米/秒。
步骤603,将路径提示信息和辅助提示信息,投影显示在目标投影面上;和/或,将路径提示信息以第二投影形式投影显示在目标投影面上,第二投影形式用于指示辅助提示信息。
在一种可能的实现方式中,移动机器人10将路径提示信息和辅助提示信息,投影显示在目标投影面上。
移动机器人10将路径提示信息投影显示在目标投影面上的同时,将辅助提示信息投影显示在目标投影面上。其中,辅助提示信息的投影形式可参考上述实施例中三种可能的路径提示信息的投影形式,在此不再赘述。
在一个示意性的例子中,如图8所示,移动机器人10沿正东方向移动,行人72沿正西方向移动,移动机器人10根据获取到的感知数据确定路径提示信息74后,在将路径提示信息74投影显示在目标投影面上的同时,将移动机器人10的预计到达时间“3s”和/或移动速度“1m/s”,投影显示在地面上。
在另一种可能的实现方式中,移动机器人10将路径提示信息以第二投影形式投影显示在目标投影面上,第二投影形式用于指示辅助提示信息。
可选的,辅助提示信息包括移动机器人10的预计到达时间,将路径提示信息以第二投影形式投影显示在目标投影面上,包括:根据移动机器人10的预计到达时间,将路径提示信息进行投影颜色的线性渐变,将线性渐变后的路径提示信息,投影显示在目标投影面上。
其中,线性渐变后的路径提示信息包括同一个投影颜色从高到低的n种色彩饱和度,n种色彩饱和度与移动机器人的预计到达时间呈正相关关系,n为正整数。其中,色彩饱和度(英文:Saturation)也称饱和度,用于指示色彩的纯度。
即移动机器人10将路径提示信息进行投影颜色的n种色彩饱和度从高至 低的线性渐变,得到线性渐变后的路径提示信息。可选的,n种色彩饱和度的取值范围为0至1。
n种色彩饱和度与移动机器人的预计到达时间呈正相关关系包括:投影颜色的色彩饱和度越高,即该投影颜色越鲜明,表示移动机器人的预计到达时间越早。
比如,色彩饱和度为“1”时用于指示移动机器人10的第一预计到达时间,色彩饱和度为“0”时用于指示移动机器人10的第二预计到达时间,由于色彩饱和度“1”高于色彩饱和度“0”,因此第一预计到达时间早于第二预计到达时间。
在一个示意性的例子中,如图9所示,移动机器人10沿正东方向移动,行人82沿正西方向移动,移动机器人10根据获取到的感知数据确定路径提示信息后,将路径提示信息进行投影颜色“棕色”的线性渐变得到线性渐变后的路径提示信息84,将线性渐变后的路径提示信息84投影显示在目标投影面上。
可选的,辅助提示信息包括移动机器人10的移动速度,移动机器人10将路径提示信息以第二投影形式投影显示在目标投影面上,包括:根据移动机器人10的移动速度,确定预定时间段内移动机器人10的移动长度,以移动长度为路径提示信息的投影长度,将路径提示信息投影显示在目标投影面上。
其中,投影长度用于指示移动机器人10的移动速度。投影长度越长,表示移动机器人10的移动速度越快。
在一个示意性的例子中,如图10所示,移动机器人10沿正东方向移动,行人92沿正西方向移动,移动机器人10根据获取到的感知数据确定移动机器人10的规划路径后,移动机器人10根据移动速度“1m/s”,确定预定时间段“5s”内移动机器人10的移动长度“5m”,将5m长的路径提示信息94投影显示在地面上。
综上所述,本实施例还通过根据障碍物的位置确定与障碍物的位置不存在重叠区域的投影区域,将路径提示信息投影显示在投影区域上;避免了将路径提示信息投影到障碍物的位置上,导致信息显示效果较差的问题,使得该移动机器人的交互方法的信息显示效果较好。
本实施例还通过根据目标投影面的平面颜色,确定不同于平面颜色的影颜色,将路径提示信息以投影颜色的形式投影显示在目标投影面上;避免路径提示信息的投影颜色与目标投影面的平面颜色一致或者相似,导致信息显示效 果较差的问题,提高了信息显示效果。
本实施例还通过将路径提示信息以第二投影形式投影显示在目标投影面上,第二投影形式用于指示辅助提示信息,使得移动机器人在向行人提供路径提示信息的同时还能够向行人提供辅助提示信息,丰富了提示信息的内容。
可选的,在步骤203或603之前,该移动机器人10的交互方法还包括:移动机器人10判断感知数据是否满足预设条件,若感知数据满足预设条件,则确定开始投影,执行步骤203或603。下面,仅以在步骤603之前还包括该步骤为例进行说明,请参考图11:
步骤1001,移动机器人10判断感知数据是否满足预设条件。
为了减少移动机器人10因为实时投影显示而导致的能源损耗,移动机器人10在开始投影前,先判断感知数据是否满足预设条件,若感知数据满足预设条件,则确定开始投影,执行步骤605;若感知数据不满足预设条件,则确定不需要投影,结束进程。
其中,预设条件包括:移动障碍物的第一位置与移动机器人10的当前位置之间的距离小于预定阈值,和/或,静止障碍物的类型为满足视觉盲点条件的障碍物类型。预定阈值可以是0-N米之间任意数值,N为正整数。本实施例对预定阈值的取值不加以限定。
由于当移动机器人10通过某些特定的路口时,由于静止障碍物的遮挡,可能造成移动机器人10与移动障碍物相互之间存在较大的盲区。为了避免相互碰撞的情况发生,若移动机器人10获取到的感知数据中静止障碍物的类型为满足视觉盲点条件的障碍物类型,则确定开始投影。
可选的,满足视觉盲点条件的障碍物类型包括出入口处的障碍物、十字路口处的障碍物、叉路口处的障碍物或转角处的障碍物中的至少一个。
可选的,若移动机器人10获取到的感知数据中静止障碍物的类型为满足视觉盲点条件的障碍物类型,则确定开始投影,将投影提示信息和辅助提示信息以特定示警图像的形式投影显示在地面上。
比如,特定示警图像为斑马线图像。本实施例对特定示警图像的形式不加以限定。
可选的,在将投影提示信息和辅助提示信息投影显示在地面上的同时,移动机器人10发出用于提示的声音信号。
可选的,在将投影提示信息和辅助提示信息投影显示在地面上的同时,将提示标识投影显示在墙面上,提示标识用于提示在预设时间段内存在移动机器人10经过。
比如,提示标识为包括倒三角形的标识,该标识中包括文本“注意”。
在一个示意性的例子中,如图12所示,移动机器人10沿正北方向移动,行人112沿正西方向移动,移动机器人10根据获取到的感知数据确定移动机器人10的规划路径,当获取到的感知数据中包括叉路口处的墙面114时,确定感知数据满足预设条件,确定开始投影,将投影提示信息和辅助提示信息以特定示警图像116的形式投影显示在地面上。
综上所述,本实施例还通过移动机器人10在开始投影前,先判断感知数据是否满足预设条件,若感知数据满足预设条件,则确定开始投影,避免了移动机器人10因为实时投影显示而导致的能源损耗问题,大大节省了移动机器人10的能源损耗。
本实施例还通过若移动机器人10获取到的感知数据中静止障碍物的类型为满足视觉盲点条件的障碍物类型,则确定开始投影,使得当移动机器人10通过某些特定的路口,即由于静止障碍物的遮挡,移动机器人10与行人之间存在较大的盲区时,移动机器人10能够通过在目标投影面上进行投影显示,向当前无法观察到该移动机器人的行人进行信息提示,大大降低了相互碰撞的风险。
