在一些实施例中，第一预设条件例如可以是语音信息中包括特定的词，也可以是对语音信息的口音进行识别，识别出的语音为特定用户的口音，在本实施例中对于第一预设条件不做具体限定。
S103：若语音信息符合第一预设条件，确定目标对象的位置。
在一些实施例中，语音信息符合了第一预设条件，此时获取目标对象的位置，目标对象例如可以为需要进行展示或特写的物体，也可以是需要进行展示或特写的人物，例如在直播中进行介绍的商品，或是使用了特定美容产品后的用户脸部，或者是在视频会议中需要展示的样品等，目标对象的位置可以采用坐标进行表示。在一些实施例中，如果语音信息不符合第一预设条 件，则重复执行步骤S101和步骤S102，直到获取的语音信息符合第一预设条件。
S104：根据目标对象的位置，对目标对象进行拍摄得到目标对象的图像。
在一些实施例中，在得到目标对象的位置后，图像采集装置自动调节摄像头从而拍摄目标对象的图像，例如对目标对象的图像进行对焦放大或者对目标对象进行特写，这样可以较为清楚的拍摄目标对象的图像，以方便查看。在另一些实施例中，图像采集装置的在拍摄目标对象前的焦距正适合拍摄目标对象，此时可以直接调节图像采集装置的拍摄视角，对目标对象进行拍摄，在另一些实施例中，在拍摄目标对象之前，可能正在对另一个较小的物体进行特写，此时目标对象相对正在特写的物体较大，因此需要适当调节焦距以缩小放大倍数放大当前视野。本公开的实施例中在需要对目标对象进行拍摄时无需用户手动操作，从而可以解放用户的双手，提高便捷性。在一些实施例中，所提出的图像采集方法还包括：将拍摄的图像发送到目标终端进行播放，目标终端例如可以是与图像采集装置通信连接观看拍摄的图像的终端，例如本公开实施例中提出的方法用于远程视频会议时，目标终端可以是远程会议的参与方观看拍摄的图像的终端，本公开实施例中提出的方法用于直播时，目标终端例如可以是观看直播的观众所使用的终端。
以下本公开实施例中提出的方法100用于视频直播带货的场景为例，对本公开提出的一个实施例进行介绍，在视频直播带货的过程中，主播使用图像采集装置进行自拍，主播会对商品进行介绍，在对商品进行介绍的时候为了使观众对商品有更为清楚的了解，往往会调节摄像头使得摄像头拍摄商品，相关技术中，需要用户手动调节摄像头以拍摄商品，导致不便，采用本公开一些实施例中提出的方法时，当主播需要拍摄商品时，主播发出语音信息，图像采集装置获取到语音信息并判断是否符合第一预设条件，在符合第一预设条件时，图像采集装置获取商品的位置并自动调节摄像头从而拍摄商品的图像，这样主播就无需在直播的过程中手动调节图像采集装置，解放了双手，方便对商品进行介绍。
由上可知，本公开一些实施例中提出的图像采集方法，用户可以通过发出语音信息，使得图像采集装置确定目标对象的位置，并对目标对象进行拍 摄，在需要向其他人展示目标对象时，无需用户手动操作图像采集装置就可以方便其他人查看到目标对象。
在本公开的一些实施例中，步骤S102判断语音信息是否符合第一预设条件，包括：判断语音信息中是否包括预设的关键词；若语音信息中包括关键词，则符合第一预设条件；或者，若语音信息中不包括关键词，则不符合第一预设条件。在本实施例中，预先设置了关键词，当用户想要拍摄目标对象的图像时，可以发出语音信息说出关键词，从而拍摄目标对象的图像，本实施例中的关键词可以由用户设定，例如可以为“实物展示”、“看这里”、“看左侧”、“看右侧”等词语。
在本公开的一些实施例中，步骤S103中的确定目标对象的位置，包括：获取用户的身体图像，根据用户的身体图像确定目标对象的位置。在本实施例中，用户的身体图像可以是用户的部分身体图像也可以是用户的全身身体图像，在用户想要介绍目标对象时，用户的身体往往会做出相应的动作，这些动作会标识目标对象的位置，因此可以根据用户的身体图像确定目标对象的位置，例如用户通常会用手指向目标对象，或者用户的双眼会看向目标对象，此时可以根据用户的手指的指向或者用户的视线方向确定到目标对象的位置。
在本公开的一些实施例中，根据用户的身体图像确定目标对象的位置，包括：判断身体图像中是否包括目标肢体的特征点；若身体图像中包括目标肢体的特征点，则根据目标肢体的特征点的位置确定目标对象的位置；或者，若身体图像中不包括目标肢体的特征点，则重新获取用户的身体图像。在本实施例中，可以先判断身体图像中是否包括目标肢体，在包括目标肢体的情况下确定目标肢体的特征点，本实施例中预先设定了目标肢体，目标肢体可以是与目标对象相关的肢体，例如可以是操作目标对象的肢体，例如可以设定目标肢体包括：手和胳膊中的至少一个。在通常情况下，用户在需要对目标对象进行展示的时候，会用手指向或者用手托起目标对象，因此可以通过目标肢体的特征点的位置确定目标对象的位置。
在一些实施例中，根据目标肢体的特征点的位置确定目标对象的位置，例如可以包括：以目标肢体的特征点为圆心，以预设距离为半径定位目标范围，在目标范围内定位目标对象，再确定目标对象的位置。在本实施例中， 考虑到用户通常采用目标肢体(例如手)来指向或承托目标对象，因此目标对象的位置通常位于目标肢体的特征点附近，因此可以在目标肢体的特征点的附近寻找并定位目标对象。通过这种方式，可以提高确定目标对象位置的速度、节省计算资源。
在本公开的一些实施例中，对目标对象进行拍摄得到目标对象的图像，包括：调节拍摄时的视角，和/或，调节拍摄时的焦距从而对目标对象进行拍摄。在本实施例中，在拍摄目标对象之前目标对象可能并不位于当前的视野内，并且采用的焦距可能并不合适，因此在对目标对象进行图像拍摄时需要调节拍摄的视角和/或拍摄的焦距，从而改善拍摄时的拍摄效果。在一些实施例中，可以预先为图像采集配置通信连接的控制器，可以响应于控制器发出的控制信息，根据控制信息调节拍摄时的视角和/或焦距，在一些实施例中，由于对目标对象进行拍摄时视野的大部分区域被目标对象占据，因此此时用户通过控制器控制视角和/或焦距也不会被图像采集装置拍摄到，方便用户选取合适的视角和/或焦距。
在本公开的一些实施例中，调节拍摄时的视角，以使目标对象位于拍摄的图像的中部。在一些实施例中，对目标对象进行拍摄的目的是为了展示目标对象，因此，调节拍摄时的视角能够更为清楚的展示目标对象。例如可以调节视角使得目标对象的坐标位于拍摄的图片的中心，从而使得目标对象位于拍摄的图像的中部，例如先以目标对象的坐标为中心，计算出目标视角，将图像采集装置的视角调整至目标视角。在本公开的一些实施例中，调节拍摄时的焦距，以提高拍摄时的放大倍数。一些实施例中，拍摄目标对象时需要展示目标对象的细节，方便其他人能够近距离观看的目标对象的细节和近景，因此需要调节拍摄时的焦距以提高拍摄时的放大倍数，从而放大目标对象的图像，此处的提高拍摄时的放大倍数是指拍摄目标对象时图像采集装置的拍摄时的放大倍率，大于对目标对象进行拍摄前的图像采集装置的放大倍率，例如在获取语音信息时图像采集装置拍摄的放大倍率为1，在拍摄目标对象时的放大倍率应当大于1，通过提高放大倍数，可以放大被拍摄的目标对象的图像，从而可以拍摄目标对象的细节，对目标对象进行特写。以本公开实施例中提出的方法用于视频会议为例，在进行视频会议时摄像头拍摄参会人员的图像并传输给远程其他参会人员，图像采集装置当前正在以1倍的 放大倍数拍摄参会人员，参会人员在需要对展品进行细节展示时，通过发出语音信息，控制图像采集装置提高放大倍数为3倍从而拍摄展品的细节对展品进行近景拍摄展示被拍摄的展品的细节，从而让远程的参会人员能够看到展品的细节，而且无需参会人员进行手动操作，解放了参会人员的双手，提高了便利性。
在本公开的一些实施例中，调节拍摄时的焦距，包括：根据显示屏的尺寸调节拍摄时的焦距；其中，显示屏用于显示拍摄的图像。在本实施例中，图像采集装置拍摄时的焦距与用于显示的显示屏的尺寸相关，例如可以设置调节拍摄时的焦距，从而使得被拍摄的目标对象的图像在显示屏上的尺寸不小于目标尺寸，和/或，使得被拍摄的目标对象的图像在显示屏上的面积与显示屏的面积比例不小于目标比例。例如通过调节焦距让被拍摄的目标对象在显示屏横向和纵向上的尺寸不小于10cm，并且，设置被拍摄的目标对象的图像的面积占显示屏的面积比例不小于75％，这样当显示屏尺寸较小时，会自动调节焦距让拍摄的目标对象的图像足够大，而当显示屏的尺寸较大时，可以自动随显示屏的面积调节焦距，也不会导致拍摄的目标对象的图像过小。
在本公开的一些实施例中，获取语音指令，根据所述语音指令调节拍摄时的视角和/或焦距。在一些实施例中，对目标对象进行拍摄时的视角和/或焦距可以使用语音的方式进行控制，以进一步调节拍摄的视角和/或焦距，语音指令可以是包括在语音信息中的，用户可以发出语音信息，并在语音信息中夹杂语音指令。
在本公开的一些实施例中，在步骤S104之后，还包括：再次获取语音信息；判断再次获取的语音信息是否符合第二预设条件；若再次获取的语音信息符合第二预设条件，将图像采集装置调节至第一状态；其中，第一状态是对目标对象进行拍摄得到目标对象的图像之前图像采集装置的状态。在本实施例中，在对目标对象进行拍摄之后，可能会无需再对目标对象进行拍摄，此时可以通过发出语音信息的方式控制图像采集装置返回到步骤S104之前图像采集装置的第一状态，本实施例中的第二预设条件例如可以是再次获取的语音信息中包括预设目标词，在识别到再次获取的语音信息中包括目标词时退出对目标对象的拍摄的状态，返回到步骤S104之前的第一状态，例如可以记录步骤S104之前图像采集装置的视角和焦距，将图像采集装置的视角和 焦距调整到步骤S104之前记录的视角和焦距，在另一些实施例中，可以记录图像采集装置在步骤S104之前所拍摄的用户和采用的焦距，在再次获取的语音信息满足第二预设条件时，控制图像采集装置再次以记录的焦距拍摄所记录的用户。
在本公开的一些实施例中，如图2所示，提出另一种图像采集方法200，图像采集方法200用于图像采集装置，包括步骤S201-步骤S203，具体如下：
S201：获取预设对象的图像。
在一些实施例中，预设对象可以为预设的物品也可以为用户的部分或全部身体，因此预设对象的图像可以是预设物品的图像或预设用户的身体图像，对此不作限定。
S202：根据预设对象的图像确定目标对象的位置。
在一些实施例中，在获取了预设对象的图像后，基于预设对象的图像定位目标对象，可以用坐标表示目标对象的位置，目标对象例如可以为需要进行展示或特写的物体，例如在直播中进行介绍的商品，或者是在视频会议中需要展示的样品等。
S203：根据目标对象的位置，对目标对象进行拍摄得到目标对象的图像。
在一些实施例中，在得到目标对象的位置后，图像采集装置自动调节摄像头从而拍摄目标对象的图像，例如对目标对象的图像进行对焦放大或者对目标对象进行特写，这样可以较为清楚的拍摄目标对象的图像，以方便查看。在另一些实施例中，图像采集装置的在拍摄目标对象前的焦距正适合拍摄目标对象，此时可以直接调节图形采集装置的拍摄视角，对目标对象进行拍摄，在另一些实施例中，在拍摄目标对象之前，可能正在对另一个较小的物体进行特写，此时目标对象相对正在特写的物体较大，因此需要适当调节焦距以放大当前视野减小放大倍数。本公开的实施例中在需要对目标对象进行拍摄时无需用户手动操作图像采集装置，从而在例如直播或视频会议等场景中无需停顿控制图像采集装置，提高了过程的流畅性和便捷性。在一些实施例中，所提出的图像采集方法还包括：将拍摄的图像发送到目标终端进行播放，目标终端例如可以是与图像采集装置通信连接的终端，例如本公开实施例中提 出的方法用于远程视频会议时，目标终端可以是远程会议的参与方，本公开实施例中提出的方法用于直播时，目标终端例如可以是观看直播的观众。
以下以本公开实施例中提出的方法200用于视频会议的场景为例，对本公开提出的一个实施例进行介绍，在远程视频会议的过程中，图像采集装置对主会场进行拍摄，分会场的参会人员通过拍摄的图形参与远程会议，主会场的参会人员在需要对展品进行介绍式，为了使分会场的参会人员对展品有更为清楚的了解，往往会调节摄像头使得摄像头拍摄展品，相关技术中，需要主会场的参会人员手动调节摄像头以拍摄展品，导致不便，采用本公开提出的方法时，以预设对象为用户的身体为例，当主会场的参会人员需要拍摄展品时，参会人员可以做出一定的身体动作，图像采集装置获取用户的身体图像，图像采集装置根据用户的身体图像获取展品的位置并自动调节摄像头从而拍摄展品的图像，这样就无需在直播会议的过程中手动调节图像采集装置，方便对展品进行介绍。
在本公开的一些实施例中，预设对象图像包括：用户的身体图像或者预设物品的图像。在一些实施例中，用户的身体图像可以是用户的全身图像，也可以是用户的部分身体的图像，其中用户的个数可以是一个也可以是多个，即可以不限定用户的数量，可以采集多个用户的身体图像。在一些实施例中，预设物品的图像例如可以是教杆、演示杆等物品的图像。
在本公开的一些实施例中，获取预设对象的图像之后，根据所述预设对象的图像确定目标对象的位置之前，还包括：确定所述预设对象的图像是否符合第三预设条件；若所述预设对象的图像符合第三预设条件，根据所述预设对象的图像确定目标对象的位置。一些实施例中，如果预设对象的图像不符合第三预设条件，则重复执行获取预设对象的图像并确定预设对象的图像是否符合第三预设条件，直到获取的身体图像符合第三预设条件。在一些实施例中，第三预设条件例如可以是用户做出了预定的动作，通过设定第三预设条件，可以在需要对目标对象进行拍摄时才进行拍摄，方便用户自主控制何时对目标对象进行拍摄。
在本公开的一些实施例中，预设对象的图像包括用户的身体图像，确定预设对象的图像是否符合第三预设条件，包括：判断身体图像中是否包括：具有目标动作的目标肢体；若是，则符合第三预设条件；或者，若否，则不 符合第三预设条件。在本实施例中，预先指定了目标肢体(目标肢体例如可以包括：手和胳膊中的至少一个)，并预先指定了目标动作，在检测到目标肢体并且目标肢体的动作为目标动作时满足第三预设条件。如果身体图像中不包括目标肢体或者目标肢体的动作不是目标动作，则不满足第三预设条件。在实际情况中，当用户需要展示目标对象时，往往会做出一定的肢体动作，例如用手指指向目标对象，或者用手掌托起目标对象，或者朝目标对象看去，这些动作都暗示了用户想要对目标对象进行展示，因此一些实施例中，具有目标动作的目标肢体包括：指向物体的手、托起物体的手、握住物体的手和看向物体的眼睛中的至少一个，可以设定上述动作为目标动作，执行上述动作的肢体为目标肢体，上述动作为用户很自然就会在需要展示目标对象时执行的动作，这样就无需用户执行额外的动作，整个过程自然流畅，不会感到突兀。本实施例中可以通过实时监测目标肢体的特征点，从而确定目标肢体的状态，从而确定是否对目标对象进行拍摄。
在一些实施例中，预设对象的图像包括：预设物品的图像，确定预设对象的图像是否符合第三预设条件包括：判断预设物品的图像中预设物品是否被握持且指向物体；若是，则满足第三预设条件，或者，若否，则不满足第三预设条件。一些实施例中，预设物品可以是演示杆等物品，用于可能会用预设物品指向目标对象，在用户使用预设物品时会握持预设物品并用指向目标对象，因此在检测到上述物品被握持且指向任一物品时，表明用户将要展示被指向的物品，此时符合第三预设条件，而当预设物品未被握持时，表明用户没有使用预设物品，而当预设物品被握持但没有指向任一物体时，表明用户可能只是拿在手里而未使用，一些实施例中，预设物品指向任一物体可以是指预设物品的预设特征点附近距离阈值内具有物品。
在一些实施例中，根据预设对象的图像确定目标对象的位置，包括：获取预设对象的图像中预设对象的特征点的位置；根据预设对象的特征点的位置确定目标对象的位置。一些实施例中，预设对象与目标对象之间的距离往往较近，因此可以依据预设对象上特征点的位置确定目标对象的位置，例如在一些实施例中，预设对象的图像包括用户的身体图像，此时确定目标对象的位置，包括：根据身体图像确定目标对象的位置。一些实施例中，在用户想要介绍目标对象时，用户的身体往往会做出相应的动作，这些动作会标识 目标对象的位置，因此可以根据用户的身体图像确定目标对象的位置，例如用户通常会用手指向目标对象，或者用户的双眼会看向目标对象，此时可以根据用户的手指的指向或者用户的视线方向确定到目标对象的位置。在一些实施例中，根据身体图像确定目标对象的位置，包括：获取身体图像中目标肢体的特征点的位置；根据目标肢体的特征点的位置确定目标对象的位置。在本实施例中预先设定了目标肢体，目标肢体可以是与目标对象相关的肢体，例如可以是操作目标对象的肢体，例如可以设定目标肢体包括：手和胳膊中的至少一个。在通常情况下，用户在需要对目标对象进行展示的时候，会用手指向或者用手托起目标对象，因此可以通过目标肢体的特征点的位置确定目标对象的位置。
在一些实施例中，根据预设对象的特征点的位置确定目标对象的位置，例如可以包括：以预设对象的特征点为圆心，以预设距离为半径定位目标范围，在目标范围内定位目标对象的位置。在一些实施例中，预设对象可以为用户的目标肢体，考虑到用户通常采用目标肢体(例如手)来指向或承托目标对象，因此目标对象的位置通常位于目标肢体的特征点附近，因此可以在目标肢体的特征点的附近寻找并定位目标对象，一些实施例中预设对象为预设物品，此时在预设物品的特征点附近定位目标对象。
在一些实施例中，对目标对象进行拍摄得到目标对象的图像，包括：调节拍摄时的视角，和/或，调节拍摄时的视角从而对目标对象进行拍摄。在本实施例中，在拍摄目标对象之前目标对象可能并不位于当前的视野内，并且采用的焦距可能并不合适，因此在对目标对象进行图像拍摄时需要调节拍摄的视角和/或拍摄的焦距，从而改善拍摄时的拍摄效果。
在一些实施例中，调节拍摄时的视角，以使目标对象位于拍摄的图像的中部；在一些实施例中，对目标对象进行拍摄的目的是为了展示目标对象，因此，调节拍摄时的视角能够更为清楚的展示目标对象。
在一些实施例中，调节拍摄时的焦距，以提高拍摄时的放大倍数。调节拍摄时的焦距，以提高拍摄时的放大倍数。一些实施例中，拍摄目标对象时需要展示目标对象的细节，方便其他人能够近距离观看的目标对象的细节和近景，因此需要调节拍摄时的焦距以提高拍摄时的放大倍数，此处的提高放大倍数是指拍摄目标对象时图像采集装置的拍摄时的放大倍率，大于对目标 对象进行拍摄前的图像采集装置的放大倍率，例如在获取语音信息时图像采集装置拍摄的放大倍率为1，在拍摄目标对象时的放大倍率应当大于1，通过提高放大倍数，可以放大被拍摄的目标对象的图像，从而可以拍摄目标对象的细节，对目标对象进行特写。
在一些实施例中，调节拍摄时的视角，包括：根据显示屏的尺寸调节拍摄时的焦距；其中，显示屏用于显示拍摄的图像。在本实施例中，图像采集装置拍摄时的焦距与用于显示的显示屏的尺寸相关，例如可以设置调节拍摄时的焦距，从而使得被拍摄的目标对象的图像在显示屏上的尺寸不小于目标尺寸，和/或，使得被拍摄的目标对象的图像在显示屏上的面积与显示屏的面积比例不小于目标比例。例如通过调节焦距让被拍摄的目标对象在显示屏横向和纵向上的尺寸不小于10cm，并且，设置被拍摄的目标对象的图像的面积占显示屏的面积比例不小于75％，这样当显示屏尺寸较小时，会自动调节焦距让拍摄的目标对象的图像足够大，而当显示屏的尺寸较大时，可以自动随显示屏的面积调节焦距，也不会导致拍摄的目标对象的图像过小。
在一些实施例中还包括获取语音指令，根据语音指令调节拍摄时的视角和/或焦距。在一些实施例中，对目标对象进行拍摄时的视角和/或焦距可以使用语音的方式进行控制，以进一步调节拍摄的视角和/或焦距，语音指令可以是包括在语音信息中的，用户可以发出语音信息，并在语音信息中夹杂语音指令。
在本公开的一些实施例，还包括：获取语音信息；判断获取的语音信息是否符合第四预设条件；若获取的语音信息符合第四预设条件，将图像采集装置调节至第二状态；其中，第二状态是对目标对象进行拍摄得到目标对象的图像之前图像采集装置的状态。本实施例中的第四预设条件例如可以是获取的语音信息中包括预设目标词，在识别到获取的语音信息中包括目标词时退出对目标对象的拍摄的状态，返回到步骤S203之前的第二状态，例如可以记录步骤S203之前图像采集装置的视角和焦距，将图像采集装置的视角和焦距调整到步骤S203之前记录的视角和焦距，在另一些实施例中，可以记录图像采集装置在步骤S203之前所拍摄的用户和采用的焦距，在获取的语音信息满足第四预设条件时，控制图像采集装置再次以记录的焦距拍摄所记录的用户。
在本公开的一些实施例中，还提出一种图像采集方法300，本实施例中的方法以用于视频会议为例进行说明，启动视频会议系统，图像采集装置拍摄会场，各方加入会议，开启语音检测线程，监听语音信息，在监听到用户发出语音信息时，确定语音信息中是否识别到预设关键词，如果没有识别到预设关键词，则继续监听语音信息，如果识别到预设关键词，则表明用户想要展示目标对象，此时获取用户的身体图像，并识别身体图像中手、骨骼等特征点，判断识别到的特征点中是否包括目标特征点，此处的目标特征点例如可以是手部特征点，如果包括目标特征点，则根据目标特征点的坐标定位展示物坐标，以展示物坐标为中心，以显示屏尺寸为参考，计算出新的视角，以此视角调节图像采集装置的方向并变焦，调节焦距放大展示物的细节，并将细节画面发给远程的参会者，这样远程的参会者就能够观看到展示物的细节之处。在无需对展示物的细节进行展示的时候，则再次发出语音信息，如果再次发出的语音信息中包括预先设定的停止特写命令，则退出对展示物的细节特写，输出原始画面，原始画面例如可以是采用对展示物进行特写前的视角和焦距拍摄的画面。
