具体实施方式
这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
目前,很多场所都安装有监控,而现有的监控系统只能进行简单的拍摄,以便后期进行调用,而在实际生活中,一旦调用有关监控,往往意味着需要对某个/某些预设人物的行踪进行确认,但这种确认方法具有明显的后滞性,且由于之前可能并没有对该预设人物的行踪进行记录,因而无法很准确地对预设人物进行追踪,无法获取到预设人物的实际行踪,可能给拍摄到预设人物的区域及该区域中的用户埋下安全隐患。
为了解决上述技术问题,本公开实施例提供了一种运动轨迹的获取方法,该方法可用于运动轨迹的获取程序、系统或装置中,且该方法对应的执行主体可以是具有拍摄功能的终端,例如:可以是XX小区/XX大楼中安装的监控系统中的终端,如图1所示,该方法包括步骤S101至步骤S105:
在步骤S101中,获取拍摄到的目标图像信息;
其中,拍摄到目标图像信息的当前拍摄设备可以是XX小区/XX大楼中的监控系统中的摄像头,或者是XX人所持的手机、平板、计算机等设备,且该目标图像信息可以是当前、或者在某段时间内拍摄到的一张或者多张图像信息。
在步骤S102中,检测目标图像信息中是否存在预设的人物信息;
预设的人物信息包括但不限于:预设图像信息、预设动作、预设步态、预设表情中的至少一项信息,例如:还可以包括人物特征信息(如脸部的痣、某种脸型、某种眼型等)。
而预设图像信息可以是手机中存储的指定人员的图像信息,或者是从当地安防系统自动下载的最新公布的逃犯、犯罪嫌疑人的图像信息等;
预设动作包括但不限于:与刀相关的动作(如持刀动作)、与枪相关的动作信息(如持枪动作)、打人的动作、拖拽的动作中的至少一项动作,
预设步态可以是踉踉跄跄的步态、跑步的步态、步行的步态等,预设表情可以是吃惊、惊恐、恐惧或者狰狞的表情等。
另外,通过检测目标图像信息中是否存在预设的人物信息,可以确定该目标图像信息中是否存在该预设的人物信息所对应的预设人物,而根据预设的人物信息的具体定义,如果存在该预设人物,则该预设人物可以是用户想要追踪的指定人员、或者是逃犯、犯罪嫌疑人等。
在步骤S103中,当目标图像信息中存在预设的人物信息时,获取拍摄到目标图像 信息的当前拍摄设备的当前地理位置;
在步骤S104中,根据当前地理位置和预设的人物信息对应的预设人物的运动状态预测预设人物的运动轨迹,其中,运动状态可以由预设的人物信息中的预设步态直接得到,或者由该预设步态推测出来;
当该目标图像信息中存在上述预设的人物信息时,可以自动获取拍摄到该目标图像信息的当前拍摄设备的当前地理位置,以便于根据当前地理位置和预设的人物信息对应的预设人物的运动状态自动而准确地预测该预设人物的运动轨迹。
在步骤S105中,开启运动轨迹上的目标拍摄设备。
目标拍摄设备和当前拍摄设备可以位于相同或者不同的监控系统中,且目标拍摄设备有可能是摄像头、或者是手机等具有拍摄功能的设备,并与当前拍摄设备可以通过有线、或者无线方式(如WiFi网络、蓝牙、移动数据网络等)相连接。
在预测出运动轨迹之后,由于预设人物的实际运动轨迹可能有所变化,因而,可以开启运动轨迹上目标拍摄设备,以唤醒这些目标拍摄设备,从而及时地对该预设人物进行真实拍摄,以准确地确定出该预设人物最终的实际运动轨迹,并对该预设人物实际的运动轨迹进行记录,以便于根据该实际的运动轨迹确定出预设人物的行踪,并避免由于之前并没有对该预设人物的行踪进行记录,使得后期无法很准确地对预设人物进行追踪,无法获取到预设人物的实际行踪,并避免给拍摄到预设人物的区域及该区域中的用户埋下安全隐患。
另外,开启目标拍摄设备还可以获取反映该预设人物实际的运动轨迹的图像数据,以便于后期通过该图像数据形象而生动地观看到预设人物的运动轨迹。
如图2所示,在一个实施例中,上述图1中的步骤S104可被执行为:
在步骤A1中,根据当前地理位置和预设的人物信息在目标图像信息中的位置,判断预设人物的当前人物位置;
在获取到该当前地理位置之后,由于当前拍摄设备对应一个拍摄区域,而预设人物也有可能在该拍摄区域中的任一位置,但预设人物位于不同位置时,预设的人物信息在目标图像信息中的位置是不同的、以及预设的人物信息所在的位置区域的大小与目标图像信息的大小的比例也是不同的,因而,根据当前地理位置和预设的人物信息在目标图像信息中的位置,可以准确地判断出预设人物的当前人物位置,即预设人物的实际位置坐标。
在步骤A2中,根据当前人物位置和运动状态预测预设人物的运动轨迹,其中,运动状态包括:预设人物的当前运动方式、预设人物的历史运动参数中的至少一项,其中,该当前运动方式可以是步行、骑自行车、骑电动车、开车、坐轮渡等,而该历史 运动参数可以是在过去的一段时间内,拍摄到包含预设的人物信息的目标图像信息时,预设人物的历史运动速率、历史运动方向等。
根据该预设人物实际的当前人物位置和其运动状态可以准确地预测出该预设人物的运动轨迹,具体地:
由于不同的当前运动方式可能对应不同的运动参数,因而,根据当前运动方式可以得到该预设人物大概的运动速率和运动方向,从而准确地预测出该预设人物的运动轨迹;或者
在获取到历史运动参数之后,可以使用一些预测运动轨迹的算法(如卡尔曼(Kalman)滤波器算法),对预设人物的运动轨迹进行预测。
如图3所示,在一个实施例中,上述图1中的步骤S105可被执行为:
在步骤B1中,获取运动轨迹上的拍摄设备;
在步骤B2中,从拍摄设备中确定出与当前地理位置之间的距离小于或等于预设距离的目标拍摄设备;
目标拍摄设备为以当前地理位置为中心,以预设距离为半径的范围内的拍摄设备,而该预设距离可以是固定的(如可以是1千米)、也可以是变化的。
在步骤B3中,开启目标拍摄设备,以对预设人物进行拍摄,并在拍摄到预设人物时,对运动轨迹进行更新。
由于运动轨迹上的拍摄设备可能很多,而较远的拍摄设备在短时间内是无法对该预设人物进行拍摄的,因而,可以选择出与该当前地理位置之间的距离小于或等于预设距离的较近的目标拍摄设备,并向这些目标拍摄设备发送开启指令,以开启目标拍摄设备,使这些目标拍摄设备处于唤醒状态,这样,预设人物在运动至目标拍摄设备的拍摄范围内时,目标拍摄设备就会对预设人物进行拍摄,且能够在拍摄到该预设人物时,自动地重新确定当前人物位置,以及时地对预测出的运动轨迹进行更新(如进行修正、完善等)。
另外,通过不断循环上述操作步骤,可以不断地对该运动轨迹进行更新,不断地对预设人物的运动轨迹进行修正和完善,从而可以得到该预设人物最新的实际运动轨迹。
如图4所示,在一个实施例中,上述方法还可包括:
在步骤S401中,在开启目标拍摄设备之后,当未拍摄到预设人物时,开启运动轨迹上与当前地理位置之间的距离大于预设距离的其他拍摄设备。
在开启目标拍摄设备之后,当未拍摄到预设人物时,说明邻近的目标拍摄设备并未追踪到该预设人物,而为了对预设人物的运动轨迹进行追踪,可以开启运动轨迹上 与当前地理位置之间的距离大于预设距离的距离较远的其他拍摄设备,以唤醒其他拍摄设备对该预设人物进行进一步追踪,从而获取到该预设人物实际的运动轨迹,以方便后期调用和追踪。
如图5所示,在一个实施例中,在执行步骤B2之前,上述方法还可包括:
在步骤S501中,根据运动状态预测预设人物的当前运动参数,其中,当前运动参数包括:当前运动速率和当前运动方向中的一项或多项;
由于不同的运动状态会对应不同的运动参数,且同一运动状态下,预设人物的运动参数在一定时间内具有相对稳定性和连贯性,不会突然变化太大,因而,可以根据其运动状态预测预设人物的当前运动参数。
在步骤S502中,根据当前运动参数和当前地理位置,确定预设距离。
由于不同的运动状态可能对应不同的当前运动参数,不同的预设距离内的拍摄设备的数目往往也是不同的,且预设人物的当前运动参数不同时,往往需要不同的数目的拍摄设备(如当该预设人物运动速率较快时,需要的拍摄设备就可能比较多,以避免漏拍该预设人物),因而,在根据运动状态预测出当前运动参数之后,可以根据当前运动参数和当前地理位置,确定与该当前运动参数且与该当前地理位置适配的预设距离,以便于调用适当数目的拍摄设备对预设人物进行拍摄,从而及时获取到该预设人物最新的实际运动轨迹。
另外,由于相同距离下,不同的地理位置下往往具有不同数目的拍摄设备,如相同距离下,山区的拍摄设备要远远少于市区,因而,在确定该预设距离时,还可以结合当前地理位置。
在一个实施例中,上述图5中的步骤B2可被执行为:
从拍摄设备中确定出与当前地理位置之间的距离小于或等于预设距离、且与当前运动方向相对应的目标拍摄设备。
在确定目标拍摄设备时,可以从拍摄设备中确定出与该当前地理位置之间的距离小于或等于预设距离,且与该当前运动方向相对应的(即相一致的)目标拍摄设备,这样,既可以以最小数目的目标拍摄设备对预设人物进行有效拍摄,以对该预设人物实际的运动轨迹进行追踪和确认,又可以减少电能的损耗。
在一个实施例中,预设的人物信息包括:预设图像信息、预设动作、预设步态、预设表情中的至少一项信息。
预设的人物信息包括但不限于:预设图像信息、预设动作、预设步态、预设表情中的至少一项信息,例如:还可以是人物特征信息(如脸部的痣、某种脸型、某种眼型等)。
对应本公开实施例提供的上述运动轨迹的获取方法,本公开实施例还提供一种运动轨迹的获取装置,如图6所示,该装置包括:

在预测出运动轨迹之后,由于预设人物的实际运动轨迹可能有所变化,因而,可以开启运动轨迹上目标拍摄设备,以唤醒这些目标拍摄设备,从而及时地对该预设人物进行真实拍摄,以准确地确定出该预设人物最终的实际运动轨迹,并对该预设人物实际的运动轨迹进行记录,以便于根据该实际的运动轨迹确定出预设人物的行踪,并避免由于之前并没有对该预设人物的行踪进行记录,使得后期无法很准确地对预设人物进行追踪,无法获取到预设人物的实际行踪,并避免给拍摄到预设人物的区域及该区域中的用户埋下安全隐患。
另外,开启目标拍摄设备还可以获取反映该预设人物实际的运动轨迹的图像数据,以便于后期通过该图像数据形象而生动地观看到预设人物的运动轨迹。

如图9所示,在一个实施例中,上述装置还可包括:
第二开启模块901,被配置为在开启目标拍摄设备之后,当未拍摄到预设人物时,开启运动轨迹上与当前地理位置之间的距离大于预设距离的其他拍摄设备。
在开启目标拍摄设备之后,当未拍摄到预设人物时,说明邻近的目标拍摄设备并未追踪到该预设人物,而为了对预设人物的运动轨迹进行追踪,可以开启运动轨迹上与当前地理位置之间的距离大于预设距离的距离较远的其他拍摄设备,以唤醒其他拍摄设备对该预设人物进行进一步追踪,从而获取到该预设人物实际的运动轨迹,以方便后期调用和追踪。
如图10所示,在一个实施例中,上述装置还可包括:
第二预测模块1001,被配置为在从拍摄设备中确定出与当前地理位置之间的距离小于或等于预设距离的目标拍摄设备之前,根据运动状态预测预设人物的当前运动参数,其中,当前运动参数包括:当前运动速率和当前运动方向中的一项或多项;
确定模块1002,被配置为根据当前运动参数和当前地理位置,确定预设距离。
由于不同的运动状态可能对应不同的当前运动参数,不同的预设距离内的拍摄设备的数目往往也是不同的,且预设人物的当前运动参数不同时,往往需要不同的数目的拍摄设备(如当该预设人物运动速率较快时,需要的拍摄设备就可能比较多,以避免漏拍该预设人物),因而,在根据运动状态预测出当前运动参数之后,可以根据当前运动参数和当前地理位置,确定与该当前运动参数且与该当前地理位置适配的预设距离,以便于调用适当数目的拍摄设备对预设人物进行拍摄,从而及时获取到该预设人物最新的实际运动轨迹。
另外,由于相同距离下,不同的地理位置下往往具有不同数目的拍摄设备,如相同距离下,山区的拍摄设备要远远少于市区,因而,在确定该预设距离时,还可以结合当前地理位置。
在一个实施例中,上述确定子模块6052可以包括:
确定单元,被配置为从拍摄设备中确定出与当前地理位置之间的距离小于或等于预设距离、且与当前运动方向相对应的目标拍摄设备。
在确定目标拍摄设备时,可以从拍摄设备中确定出与该当前地理位置之间的距离小于或等于预设距离,且与该当前运动方向相对应的(即相一致的)目标拍摄设备,这样,既可以以最小数目的目标拍摄设备对预设人物进行有效拍摄,以对该预设人物实际的运动轨迹进行追踪和确认,又可以减少电能的损耗。
