为了解决上述技术问题，本申请实施例提供了一种模拟摄像机、服务器、监控系统和数据传输、处理方法。下面首先对本申请实施例提供的一种模拟摄像机进行详细说明。
图1为本申请实施例提供的模拟摄像机的第一种结构示意图，包括：
图像采集芯片100、图像分析芯片200、集成芯片300和发送芯片400，图像采集芯片100分别与图像分析芯片200、集成芯片300相连接，图像分析芯片200与集成芯片300相连接，集成芯片300与发送芯片400相连接；
图像采集芯片100，用于采集数字视频流数据；
图像分析芯片200，用于对所述数字视频流数据进行分析，识别所述数字 视频流数据中存在的目标，提取所述目标的属性和/或位置信息；并将所述目标的属性和/或位置信息发送到集成芯片300；
集成芯片300，用于根据预设插入模式，将所述目标的属性和/或位置信息插入至所述数字视频流数据中，得到混合数据，并将所述混合数据发送到发送芯片400；
发送芯片400，用于将所述混合数据、或者所述混合数据中的数字视频流数据转换为模拟数据，得到转换后的混合数据；发送所述转换后的混合数据。
应用本申请图1所示实施例，模拟摄像机中包含图像分析芯片，该图像分析芯片对采集到的数字视频流数据进行分析，识别数字视频流数据中存在的目标，提取目标的属性和/或位置信息；并将目标的属性和/或位置信息发送到集成芯片，集成芯片根据预设插入模式，将目标的属性和/或位置信息插入至数字视频流数据中，得到混合数据；可见，本方案中的模拟摄像机实现了对采集到的图像进行分析处理。
下面对图1所示实施例进行详细说明：
图像采集芯片100将光信号转化为图像数字信号，得到数字视频流数据。图像采集芯片100可以为图像sensor(传感器)，或者，也可以为其他，具体不做限定。
作为一种实施方式，图像采集芯片100可以将数字视频流数据进行复制，得到两份数字视频流数据，一份发送到图像分析芯片200，另一份发送到集成芯片300。
图像分析芯片200对接收到的数字视频流数据进行分析，通过分析识别数字视频流数据中存在的目标。举例来说，可以利用人脸识别，识别出数字视频流数据中的人脸区域，或者，可以利用车牌识别，识别出数字视频流数据中的车牌，等等，具体分析方式不做限定。识别出目标后，可以提取目标的属性，比如，人脸特征、车牌号等，或者，也可以确定目标在视频图像中的位置信息。
为了方便描述，将图像分析芯片200分析得到的目标的属性和/或位置信息称为图像分析数据。图像分析芯片200将该图像分析数据发送给集成芯片 300。这样，集成芯片300既接收到了图像采集芯片100发送的数字视频流数据，又接收到了图像分析芯片200发送的图像分析数据。
集成芯片300根据预设插入模式，将该图像分析数据插入至数字视频流数据中，得到混合数据。插入模式有多种，比如，将图像分析数据插入数字视频流数据中的消隐区，或者，采用前半帧数字视频流数据、后半帧图像分析数据的插入模式，或者，采用n帧数字视频流数据、一帧图像分析数据的插入模式，等等，具体不做限定。
作为一种实施方式，集成芯片300还可以从数字视频流数据中抓取携带有该目标的图像；该目标与图像分析数据中的属性和/位置信息指向的目标为同一目标。
集成芯片300与图像分析芯片200可以同时对数字视频流数据进行处理，这样，集成芯片300抓取的图像与图像分析芯片200分析的图像为同一张图像，因此，图像分析芯片200识别出的目标存在于集成芯片300抓取的图像中。
为了方便描述，本实施方式中，将图像分析芯片200分析得到的目标的属性和/或位置信息、以及集成芯片300抓取的图像都称为图像分析数据。然后，集成芯片300根据预设插入模式，将图像分析数据插入至数字视频流数据中，得到混合数据，并将混合数据发送到所述发送芯片400。
本实施方式中，混合数据中不仅包含目标的属性和/或位置信息，还包含携带有目标的图像，混合数据中携带的与目标相关联的信息更丰富。
作为一种实施方式，集成芯片抓取到图像、并将该图像发送至图像分析芯片后，可以对该图像进行压缩，得到压缩后的图像，根据预设插入模式，将压缩后的图像、目标的属性和/或位置信息插入至数字视频流数据中，得到混合数据，并将混合数据发送到所述发送芯片400。
应用这种实施方式，将图像进行压缩，混合数据占用的空间更小，模拟摄像机对混合数据进行发送时，占用的数据带宽更小。
上面内容中“图像采集芯片100可以将数字视频流数据进行复制，得到两 份数字视频流数据，一份发送到图像分析芯片200，另一份发送到集成芯片300”，作为另一种实施方式，图像采集芯片也可以不对数字视频流数据进行复制，仅将一份数字视频流数据发送到集成芯片300。
这种实施方式中，集成芯片300可以在数字视频流数据中抓取图像，将所抓取的图像发送给图像分析芯片200；图像分析芯片200接收该图像，对该图像进行分析，识别所述图像中存在的目标，提取所述目标的属性和/或位置信息；并将所述目标的属性和/或位置信息发送到集成芯片300。
集成芯片300可以根据预设插入模式，将所述目标的属性和/或位置信息插入至所述数字视频流数据中，得到混合数据；或者，集成芯片300可以根据预设插入模式，将抓取的图像、所述目标的属性和/或位置信息插入至所述数字视频流数据中，得到混合数据。
这种实施方式中，集成芯片300在将抓取的图像发送给图像分析芯片200后，可以将所抓取的图像进行压缩，得到压缩后的图像；并根据预设插入模式，将所述压缩后的图像、所述目标的属性和/或位置信息插入至所述数字视频流数据中，得到混合数据。这样，混合数据占用的空间更小，模拟摄像机对混合数据进行发送时，占用的数据带宽更小。
在上述几种实施方式中，集成芯片在数字视频流数据中插入的数据或有不同，比如，一些实施方式中，仅插入目标的属性和/或位置信息；在另一些实施方式中，插入目标的属性和/或位置信息、以及抓取的图像；在另一些实施方式中，插入目标的属性和/或位置信息、以及压缩后的图像；为了方便描述，可以将这些插入的数据都称为图像分析数据。
将图像分析数据插入数字视频流数据的方式有多种，比如，将图像分析数据插入数字视频流数据中的消隐区，或者，采用前半帧数字视频流数据、后半帧图像分析数据的插入模式，或者，采用n帧数字视频流数据、一帧图像分析数据的插入模式，等等，具体不做限定。
作为一种实施方式，集成芯片在将图像分析数据插入数字视频流数据后，还可以根据预设排列方式，对插入所述消隐区的图像分析数据进行排列，得到排列后数据；将所述排列后数据转换为预设格式的数据；将所述数字视频 流数据转换为相同格式的数据。
举例来说，可以将图像分析数据进行结构化排列，比如，可以确定图像分析数据的数据量的大小、数据类型等信息，将这些信息作为头部信息添加至图像分析数据的前面，添加了头部信息的图像分析数据即为排列后的数据。结构化排列的方式有多种，具体不做限定。
然后将排列后的数据转换为BT1120格式的数据；将数字视频流数据转换为BT1120格式的数据。或者，也可以将这两种数据转换为其他格式的数据，具体不做限定。
对于数字视频流数据来说，通常需要将其转换为模拟数据进行发送；而对于图像分析数据来说，也就是上述分析得到的“目标的属性和/或位置信息”、或者“目标的属性和/或位置信息、及抓取的图像”、或者“目标的属性和/或位置信息、及压缩后的图像”，可以将图像分析数据转换为模拟数据进行发送，也可以不进行数模转换，发送数字数据。
作为一种实施方式，发送芯片400可以将混合数据转换为模拟混合数据，发送该模拟混合数据。

根据前面内容描述，图像分析数据可以包括：“目标的属性和/或位置信息”、或者“目标的属性和/或位置信息、及抓取的图像”、或者“目标的属性和/或位置信息、及压缩后的图像”。
应用这种实施方式，一方面仅将数字视频流数据进行数模转换，不对图像分析数据进行数模转换，这样，可以避免对图像分析数据进行数模转换、 模数转换造成的数据丢失、或其他未知错误。另一方面，将图像分析数据转换为低频数字数据进行传输，消耗能量较小。
在本申请实施例中，集成芯片300可以包含多个集成设置的芯片，作为一种实施方式，可以如图2所示，发送芯片400集成设置在集成芯片300中，或者说，集成芯片300包含发送芯片400。
或者，在其他实施方式中，发送芯片400也可以单独设置，具体不做限定。
作为一种实施方式，可以如图3所示，集成芯片300中包含图像处理芯片500和插入芯片600，
图像处理芯片500，用于对所述数字视频流数据进行色彩和/或亮度处理；
插入芯片600，用于根据预设插入模式，将所述目标的属性和/或位置信息插入至处理后的数字视频流数据中，得到混合数据。
举例来说，图像处理芯片500可以为ISP(Image Signal Processing，图像信号处理)芯片，或者，也可以为MCU(Microcontroller Unit，微控制单元)。
图像处理芯片500对数字视频流数据进行色彩和/或亮度处理，可以包括：AEC(Automatic Exposure Control，自动曝光控制)、AGC(Automatic Gain Control，自动增益控制)、AWB(Automatic white balance，自动白平衡)、色彩校正等处理，具体不做限定。
集成芯片中还可以集成其他芯片，或者说，集成芯片还可以包含其他芯片，具体不做限定。将多个芯片集成设置，可以减少占用的模拟摄像机中的空间，使模拟摄像机结构更紧凑，体积更小。
本申请实施例还提供一种模拟摄像机侧的数据处理方法，如图4所示，该方法包括：
S401：采集数字视频流数据。
S402：对所述数字视频流数据进行分析，识别所述数字视频流数据中存在的目标，提取所述目标的属性和/或位置信息。

S405：发送所述转换后的混合数据。
应用本申请图4所示实施例，模拟摄像机对采集到的数字视频流数据进行分析，识别数字视频流数据中存在的目标，提取目标的属性和/或位置信息；根据预设插入模式，将目标的属性和/或位置信息插入至数字视频流数据中，得到混合数据；可见，本方案中的模拟摄像机实现了对采集到的图像进行分析处理。
下面对图4所示实施例进行详细说明：
S401：采集数字视频流数据。
模拟摄像机中通常设置有图像采集芯片，图像采集芯片可以将光信号转化为图像数字信号，得到数字视频流数据。
S402：对所述数字视频流数据进行分析，识别所述数字视频流数据中存在的目标，提取所述目标的属性和/或位置信息。
举例来说，可以利用人脸识别，识别出数字视频流数据中的人脸区域，或者，可以利用车牌识别，识别出数字视频流数据中的车牌，等等，具体分析方式不做限定。识别出目标后，可以提取目标的属性，比如，人脸特征、车牌号等，或者，也可以确定目标在视频图像中的位置信息。
S403：根据预设插入模式，将所述目标的属性和/或位置信息插入至所述数字视频流数据中，得到混合数据。
作为一种实施方式，在S402之后，还可以在所述数字视频流数据中抓取携带有该目标的图像。该目标与图像分析数据中的属性和/位置信息指向的目标为同一目标。
举例来说，在S401之后，可以将采集到的数字视频流数据进行复制，得到两份数字视频流数据。这样，S402包括：对所述两份数字视频流数据中的一份数字视频流数据进行分析，识别该一份数字视频流数据中存在的目标， 提取所述目标的属性和/或位置信息。另外，在所述两份数字视频流数据中的另一份数字视频流数据中抓取携带有所述目标的图像。
这种实施方式中，S403包括：根据预设插入模式，将所抓取的图像、所述目标的属性和/或位置信息插入至所述数字视频流数据中，得到混合数据。
可见，本实施方式中，混合数据中不仅包含目标的属性和/或位置信息，还包含携带有目标的图像，混合数据中携带的与目标相关联的信息更丰富。
作为一种实施方式，在数字视频流数据中抓取携带有该目标的图像之后，还可以对所抓取的图像进行压缩，得到压缩后的图像；这种实施方式中，S403包括：根据预设插入模式，将所述压缩后的图像、所述目标的属性和/或位置信息插入至所述数字视频流数据中，得到混合数据。
应用这种实施方式，将图像进行压缩，混合数据占用的空间更小，模拟摄像机对混合数据进行发送时，占用的数据带宽更小。
为了方便描述，将上述分析得到的“目标的属性和/或位置信息”、或者“目标的属性和/或位置信息、及抓取的图像”、或者“目标的属性和/或位置信息、及压缩后的图像”都称为图像分析数据。上述不同的实施方式中，图像分析数据不同。这样，S403包括：根据预设插入模式，将图像分析数据插入至所述数字视频流数据中，得到混合数据。
插入模式有多种，比如，将图像分析数据插入数字视频流数据中的消隐区，或者，采用前半帧数字视频流数据、后半帧图像分析数据的插入模式，或者，采用n帧数字视频流数据、一帧图像分析数据的插入模式，等等，具体不做限定。
S404：将所述混合数据、或者所述混合数据中的数字视频流数据转换为模拟数据，得到转换后的混合数据。
对于数字视频流数据来说，通常需要将其转换为模拟数据进行发送；而对于图像分析数据来说，可以将其转换为模拟数据进行发送，也可以不进行 数模转换，发送数字数据。因此，在本实施例中，可以仅将混合数据中的数字视频流数据转换为模拟数据，也可以将混合数据全部转换为模拟数据。
作为一种实施方式，S404可以包括：将所述混合数据中的数字视频流数据转换为模拟视频流数据；将所述混合数据中的图像分析数据转换为低频数字数据。所述图像分析数据也就是上述分析得到的“目标的属性和/或位置信息”、或者“目标的属性和/或位置信息、及抓取的图像”、或者“目标的属性和/或位置信息、及压缩后的图像”。
应用这种实施方式，一方面仅将数字视频流数据进行数模转换，不对图像分析数据进行数模转换，这样，可以避免对图像分析数据进行数模转换、模数转换造成的数据丢失、或其他未知错误。另一方面，将图像分析数据转换为低频数字数据进行传输，消耗能量较小。
作为一种实施方式，S404可以包括：
根据预设排列方式，对插入所述消隐区的图像分析数据进行排列，得到排列后数据；将所述排列后数据、以及所述数字视频流数据转换为预设格式的数据；将所述预设格式的数据进行数模转换，得到转换后的混合数据。
举例来说，可以将图像分析数据进行结构化排列，比如，可以确定图像分析数据的数据量的大小、数据类型等信息，将这些信息作为头部信息添加至图像分析数据的前面，添加了头部信息的图像分析数据即为排列后的数据。结构化排列的方式有多种，具体不做限定。
然后将排列后的数据转换为BT1120格式的数据；将数字视频流数据转换为BT1120格式的数据。或者，也可以将这两种数据转换为其他格式的数据，具体不做限定。
S405：发送所述转换后的混合数据。
作为一种实施方式，模拟摄像机可以将上述得到的转换后的混合数据发送至相连的服务器。
本申请实施例还提供了多种数据传输方法，以传输上述转换后的混合数据。下面通过具体实施例，对第一种数据传输方法进行详细说明。第一种数据传输方法包括如下步骤：S501～S502：
S501：连续发送预设数量个第二种图像帧。第二种图像帧为携带视频流数据且不携带目标数据的图像帧，目标数据包括上述得到的目标的属性和/或位置信息。
模拟摄像机发送的图像帧可以如图6所示，该图像帧包括有效图像区和消隐区。本实施例中，第一种图像帧与第二种图像帧为不同种类的图像帧，第二种图像帧携带视频流数据且不携带目标数据，而第一种图像帧有效图像区携带目标数据。有效图像区也可以称为数据区。
本实施例中，视频流数据也就是图像数据。模拟摄像机可以采集图像数据(视频流数据)并将采集的图像数据发送至服务器。
同轴数据为服务器和模拟摄像机之间交互的通知信息。该同轴数据也可以称为PTZ数据。当模拟摄像机和服务器分别为视频生成端和视频接收端时，视频生成端和视频接收端之间交互的同轴数据可以包括视频生成端向视频接收端发送的同轴发送数据，也可以包括视频接收端向视频生成端发送的同轴接收数据。例如，视频接收端为硬盘录像机(Digital Video Recorder，DVR)时，同轴数据可以包括模拟摄像机向DVR发送的拍摄模式信息、升级时准备就绪的信息等，也可以包括模拟摄像机与DVR之间的握手数据，该握手数据可以用于发送表示设备类型、图像分辨率的数据等；同轴数据还可以包括DVR向模拟摄像机发送的控制信息，该控制信息可以包括针对摄像机的控制指令，例如图像参数调节指令、摄像机光圈调节指令、摄像机旋转调节指令、分辨率切换指令、远程升级数据指令等。同轴数据还可以包括图像数据在图像帧中的位置以及目标数据在图像帧中的位置等信息。
图像帧中可以包括同轴数据，也可以不包括同轴数据。
S502：将目标数据作为第一种图像帧的有效图像区携带的数据，采用有效图像区的数据发送方式，发送目标数据；其中，所述第一种图像帧与所述第二种图像帧占用同一传输通道。
上述“转换后的混合数据”包括视频流数据和目标数据，因此，通过S501和S502，实现了对“转换后的混合数据”的发送。
其中，传输通道可以为同轴线缆、双绞线或其他传输材料，本申请对此不做具体限定。同一传输通道可以理解为同一根线。
在本实施例中，模拟摄像机与服务器之间可以交替地发送第一种图像帧和第二种图像帧。第一种图像帧的有效图像区用于发送目标数据，第二种图像帧的有效图像区用于发送图像数据，也就是视频流数据。这样，能够通过同一传输通道，实现对视频流数据和目标数据的发送。
模拟摄像机与服务器之间传输视频流数据时可以使用同轴线缆或双绞线。为了发送目标数据，同时避免另外布线，可以通过与传输视频流数据时使用的同一传输通道进行传输。
由上述内容可知，本实施例可以获取待发送的目标数据，通过与传输视频流数据时使用的同一传输通道，将目标数据作为第一种图像帧的有效图像区携带的数据，采用有效图像区的数据发送方式，发送该目标数据。其中，第一种图像帧的种类与携带视频流数据且不携带目标数据的第二种图像帧的种类不同。因此，本实施例提供的方案，能够实现模拟摄像机将目标数据通过与传输视频流数据时使用的同一传输通道发送至服务器，无需另外布线，从而能够节省设备成本。
在本实施例中，第一种图像帧的消隐区也可以用来传输目标数据。例如，当目标数据的数据量很大时，第一种图像帧的有效图像区无法发送全部的目标数据时，可以通过消隐区中的部分位置发送剩余的目标数据。该部分位置可以为消隐区中除了用于发送同轴数据的位置之外的位置。第一种图像帧和第二种图像帧可以是按照预设规律间隔性地发送的，也可以是随机发送的。详见以下实施例。
在本实施例中，S502可以包括：确定是否已经连续发送预设数量个第二种图像帧，当确定已经连续发送预设数量个第二种图像帧时，将所述目标数据作为第一种图像帧的有效图像区携带的数据，采用有效图像区的数据发送方式，发送所述目标数据；其中，所述第一种图像帧与所述第二种图像帧占 用同一传输通道。
本实施例中，用于发送目标数据的第一种图像帧的数量可以是预先设定的，也可以是根据目标数据的数据量确定的。用于发送目标数据的第一种图像帧的数量，可以为一个，也可以为多个。
当目标数据发送完成时，还可以连续发送预设数量个第二种图像帧。
在本实施例中，可以每发送N个携带图像数据的第二种图像帧，发送M个携带目标数据的第一种图像帧，再发送N个携带图像数据的第二种图像帧，依此重复。其中，N的值可以固定也可以不固定，M的值可以固定也可以不固定。
第一种情况中，N为固定的值，M为不固定的值。具体的，M可以为：目标数据的数据量除以单个第一种图像帧的有效图像区的数据量之后得到的数量。例如，已知单个第一种图像帧的有效图像区可以发送2000行数据，每行可以传输100kB数据，则单个第一种图像帧的有效图像区大概可以传输0.2MB的数据。当目标数据的数据量为2MB时，则传输这些目标数据需要采用M个第一种图像帧，M＝2MB/0.2MB＝10。因此，需要10个第一种图像帧传输这些目标数据。
作为一个例子，图7a为第一种图像帧和第二种图像帧在发送时的一种排列示意图。其中，空心矩形代表第二种图像帧，实心矩形代表第一种图像帧。N的值是固定的5帧，M的值是不固定的，可能为2、1、4、1、3等值。
第二种情况中，N为固定的值，M为固定的值。在这种实施方式中，图像数据和目标数据以固定的间隔进行发送。采用这种方式发送的第一种图像帧和第二种图像帧是均匀排列的，在服务器接收图像数据时，可以保证图像预览时的流畅度。
作为一个例子，图7b为第一种图像帧和第二种图像帧在发送时的另一种排列示意图。其中，空心矩形代表第二种图像帧，实心矩形代表第一种图像帧。N的值是固定的5帧，M的值为固定的2帧。
第三种情况中，第一种图像帧的数量N和第二种图像帧的数量M均可以是随机的，即N为不固定的值，M也为不固定的值。在这种情况中，获取目 标数据的时刻可以是不固定的，每次获取的目标数据的数据量也可以是不固定的。两种图像帧的排列可以是杂乱无章的。
作为一个例子，图7c为第一种图像帧和第二种图像帧在发送时的又一种排列示意图。其中，空心矩形代表第二种图像帧，实心矩形代表第一种图像帧。可见，该图7c中N和M的值均为随机的。
第四种情况中，N为不固定的值，M为固定的值。在这种情况中，获取目标数据的时刻可以是不固定的，但每次获取的目标数据的数据量可以是固定的。
作为一个例子，图7d为第一种图像帧和第二种图像帧在发送时的再一种排列示意图。其中，空心矩形代表第二种图像帧，实心矩形代表第一种图像帧。可见，该图7c中N的值为不固定的，M的值为固定的2。
当N和/或M的值为不固定的时，可以通过在图像帧中添加同轴数据的方式标识该图像帧为第一种图像帧，以使服务器从接收的图像帧中确定第一种图像帧。具体的，同轴数据可以包括表示图像帧的有效图像区中的数据为目标数据的数据，根据该数据可以确定该图像帧为第一种图像帧。
在本申请的另一实施例中，发送所述转换后的混合数据，可以包括：
判断待发送的目标数据的数据量是否达到预设数据量阈值；所述目标数据包括所述目标的属性和/或位置信息；
如果达到，将所述目标数据作为第一种图像帧的有效图像区携带的数据，采用有效图像区的数据发送方式，发送所述目标数据；
如果未达到，发送第二种图像帧，所述第二种图像帧为携带视频流数据且不携带目标数据的图像帧，其中，所述第一种图像帧与所述第二种图像帧占用同一传输通道。
其中，预设数据量阈值可以是预设值，例如可以是单个图像帧的有效图像区能够存储的最大数据量，也可以为该最大数据量的a倍，a为正整数。或者，预设数据量阈值也可以为其他任意值。
当预设数据量阈值为最大数据量时，可以每次采用一个第一种图像帧发 送目标数据。当预设数据量阈值为最大数据量的a倍时，可以每次连续发送a个第一种图像帧。如果a值大于指定数值时，为了保证服务器的图像流畅性，第二种图像帧不能长时间没有，这种情况下第一种图像帧可以与第二种图像帧间隔性发送。
目标数据可以在有效图像区中的位置，可以是固定的，也可以是不固定的。当目标数据在有效图像区中的位置不固定时，可以通过目标数据携带的所述目标数据起始位置的头标识，以及表示目标数据末尾位置的尾标识来确定目标数据的位置。其中，头标识可以为第一预设比特串，尾标识可以为第二预设比特串。目标数据的前第一预设数量个比特位可以为第一预设比特串，目标数据的后第二预设数量个比特位可以为第二预设比特串。
在本申请的另一实施例中，在发送所述转换后的混合数据之前，该方法还可以包括：获取待发送的同轴数据；这样，将同轴数据作为与目标数据所在的第一种图像帧的消隐区携带的数据，采用消隐区的数据发送方式，发送同轴数据。
作为一个例子，图7e为模拟摄像机向服务器发送两种图像帧的一种传输架构图。其中，第一种图像帧包括目标数据和同轴数据，第二种图像帧包括视频流数据(图像数据)和同轴数据。其中，同轴数据是可选的，这两种图像帧也可以不包括同轴数据。
可见，本实施例可以将同轴数据和目标数据均通过第一种图像帧发送至服务器，能够使传输的数据种类更丰富，数据传输效率更高。
在上述实施例中，同轴数据还可以包括：表示图像帧的有效图像区中的数据为目标数据的同轴数据标识。这样，服务器可以根据同轴数据中的同轴数据标识确定图像帧的有效图像区的数据为目标数据。在另一实施方式中，同轴数据也可以包括表示图像帧的有效图像区的数据不为目标数据的标识。有效图像区的数据不为目标数据时，有效图像区的数据可以为图像数据，也可以为其他数据或没有数据等。例如，同轴数据的指定位置的数据为1时，表示图像帧的有效图像区的数据为目标数据，当该指定位置的数据为0时，表示图像帧的有效图像区的数据不为目标数据。当服务器接收到图像帧时，可以从该图像帧中获取同轴数据，根据同轴数据的指定位置的数据确定图像 帧的有效图像区的数据是否为目标数据。
当第一种图像帧和第二种图像帧排列不规则时，即N和/或M的值不固定时，为了能够确定哪个图像帧携带目标数据，可以根据同轴数据是否包含表示图像帧的有效图像区中的数据为目标数据的数据来判断，当确定包含表示图像帧的有效图像区中的数据为目标数据的数据时，认为图像帧为第一种图像帧，否则，认为图像帧为第二种图像帧。
其中，表示图像帧的有效图像区中的数据为目标数据的同轴数据标识，可以以指定标识来实现，也可以通过其他方式实现，本申请对此不作具体限定。
在上述实施例中，同轴数据还可以包括表示目标数据在有效图像区的位置的数据。目标数据可以占满有效图像区，也可以不占满有效图像区。当目标数据占满有效图像区时，同轴数据中表示目标数据在有效图像区的位置的数据可以为有效图像区的位置。当目标数据没有占满有效图像区时，同轴数据中表示目标数据在有效图像区的位置的数据可以为目标数据的实际位置。服务器可以根据同轴数据中的数据确定有效图像区中目标数据的位置，从而更准确地获取目标数据。
可见，本实施例中同轴数据可以包括表示图像帧的有效图像区中的数据为目标数据的同轴数据标识，根据该同轴数据标识确定图像帧属于第一种图像帧或第二种图像帧，能够使服务器更准确地获取目标数据。
本实施例中，为了能够实现采用完整的一图像帧传输目标数据，可以提高传输参数，以使保证对图像数据和目标数据的传输。例如，原来的传输参数为2MP25，该参数可以理解为2百万像素的图像每秒传输25帧。原来以2MP25传输参数可以实现对图像数据的传输。为了传输目标数据，可以将2MP25提高到2MP30。这样，每传输30个携带图像数据的图像帧，就会有5个图像帧是不需要存储图像数据的。这些闲置的图像帧就可以用来发送目标数据。
作为一个例子，图7f中给出了分别携带视频流数据和目标数据的图像帧的一种发送方式。
本申请实施例还提供了第二种数据传输方法，以传输上述转换后的混合数据。下面通过具体实施例，对第二种数据传输方法进行详细说明。如图8所示，该方法包括如下步骤：S801～S802：
S801：确定视频流数据在图像帧的有效图像区中的第一位置，以及确定目标数据在图像帧的有效图像区中的第二位置，所述目标数据包括所述目标的属性和/或位置信息。
其中，目标数据为不同于视频流数据和同轴数据的数据。同轴数据为服务器和模拟摄像机之间交互的通知信息，该同轴数据也可以称为PTZ数据。当模拟摄像机和服务器分别为视频生成端和视频接收端时，视频生成端和视频接收端之间交互的同轴数据可以包括视频生成端向视频接收端发送的同轴发送数据，也可以包括视频接收端向视频生成端发送的同轴接收数据。例如，当视频接收端为硬盘录像机(Digital Video Recorder，DVR)时，同轴数据可以包括模拟摄像机向DVR发送的拍摄模式信息、升级时准备就绪的信息等，也可以包括模拟摄像机与DVR之间的握手数据，该握手数据可以用于发送表示设备类型、图像分辨率的数据等；同轴数据还可以包括DVR向模拟摄像机发送的控制信息，该控制信息可以包括针对模拟摄像机的控制指令，例如图像参数调节指令、摄像机光圈调节指令、摄像机旋转调节指令、分辨率切换指令、远程升级数据指令等。同轴数据还可以包括视频流数据在图像帧中的位置以及目标数据在图像帧中的位置等信息。
图像帧中可以包括同轴数据，也可以不包括同轴数据。
S802：将视频流数据以及目标数据作为同一图像帧的数据，采用有效图像区的数据发送方式，按照第一位置发送视频流数据，按照第二位置发送目标数据。
上述“转换后的混合数据”包括视频流数据和目标数据，因此，通过S801和S802，实现了对“转换后的混合数据”的发送。
在S801中，确定视频流数据在图像帧的有效图像区中的第一位置时，可以将第一预设位置确定为视频流数据在图像帧的有效图像区中的第一位置，预设位置包括起始位置和末尾位置。也可以根据视频流数据的数据量，确定 视频流数据在图像帧的有效图像区中的第一位置。
根据视频流数据的数据量，确定视频流数据在图像帧的有效图像区中的第一位置时，具体可以为，将视频流数据在图像帧的有效图像区中的第一位置确定为：从第一预设初始位置开始，到第一末尾位置；其中，第一末尾位置为：第一预设初始位置加视频流数据的数据量后得到的位置。第一预设初始位置和第一末尾位置均位于有效图像区。
在S801中，确定目标数据在有效图像区中的第二位置时，可以将第二预设位置确定为目标数据在有效图像区中的第二位置。也可以根据目标数据的数据量，确定目标数据在有效图像区中的第二位置。
根据目标数据的数据量，确定目标数据在有效图像区中的第二位置时，具体可以为，将目标数据在有效图像区中的第二位置确定为：从第二预设初始位置开始，到第二末尾位置；其中，第二末尾位置为：第二预设初始位置加目标数据的数据量后得到的位置。第二预设初始位置和第二末尾位置均位于有效图像区。
上述第二位置可以是图像帧有效图像区的固定位置，也可以是不固定的位置。当有效图像区中视频流数据的位置是固定位置时，目标数据在有效图像区的第二位置可以是有效图像区中除视频流数据的位置之外的位置。例如，第二位置可以为有效图像区中除视频流数据的位置之外的部分区域的位置，也可以为有效图像区中除视频流数据的位置之外的全部区域的位置，本申请对此不做具体限定。
本实施例中，视频流数据也就是图像数据，模拟摄像机可以采集图像数据(视频流数据)并将采集的图像数据发送至服务器。
为了能够在有效图像区中同时传输图像数据和目标数据，可以提高模拟摄像机与服务器传输的图像帧的分辨率规格，可以使用高规格的传输频率来传输低规格的分辨率。例如，可以使用4MP30的传输参数来传输原来用2MP30的传输参数传输的数据。其中，传输参数xMPy可以理解为，每秒传输y帧x百万像素的数据。在使用4MP30的传输参数传输数据时，有效图像区传输的行数增加了，每一行能够传输的数据量也增加了，因此在传输图像数据时， 可以使有效图像区出现大片的闲置区，这些闲置区可以用来存储目标数据。
当第二位置为固定的位置时，服务器和模拟摄像机可以预先约定第二位置，从而使服务器可以按照约定的第二位置获取目标数据，提高获取目标数据时的准确性。
当第二位置为不固定的位置时，目标数据可以包括表示目标数据的起始位置的头标识，以及表示目标数据的末尾位置的尾标识。这样，当服务器在获取目标数据时，可以根据上述头标识确定目标数据的起始位置，根据上述尾标识确定目标数据的末尾位置，根据确定的目标数据的起始位置和目标数据的末尾位置，从有效图像区获取目标数据，从而在第二位置不固定时能够准确地获取目标数据。这种实施方式中目标数据发送时的灵活性比较大。
其中，头标识可以为第一预设比特串，尾标识可以为第二预设比特串。目标数据的前第一预设数量个比特位可以为第一预设比特串，目标数据的后第二预设数量个比特位可以为第二预设比特串。
在图像帧中，有效图像区的数据量远大于消隐区的数据量。如果将有效图像区的一部分分配给目标数据，则目标数据可以为数据量很大的数据。
在本实施例中，将视频流数据和目标数据通过同一图像帧发送至后端的电子设备，可以通过同一线缆实现对上述“转换后的混合数据”的发送。
在发送上述图像帧时，可以将图像帧中的数据逐行地以数据流的形式进行发送，也可以将图像帧中的数据逐列地以数据流的形式进行发送。
由上述内容可知，本实施例确定视频流数据在图像帧的有效图像区中的第一位置，以及确定目标数据在图像帧的有效图像区中的第二位置，将视频流数据以及目标数据作为同一图像帧的数据，按照第一位置发送视频流数据，按照第二位置发送目标数据。因此，本实施例可以实现将上述“转换后的混合数据”以同一图像帧发送至电子设备，无需另外布线，能够节省设备成本。
在模拟摄像机向服务器发送的大量图像帧中，可以在所有图像帧中均携带目标数据，也可以在部分图像帧中携带目标数据。当获取到目标数据时，可以将有效图像区携带视频流数据和目标数据的图像帧发送至服务器。当没有获取到目标数据时，可以将有效图像区携带视频流数据、有效图像区不携 带目标数据的图像帧发送至服务器。
在本申请的另一实施例中，在发送视频流数据和目标数据之前，该方法还可以包括以下步骤1～步骤2：
步骤1：获取待发送的同轴数据，以及确定同轴数据在图像帧的消隐区的第三位置。
本实施例中，图像帧中包括视频流数据、目标数据和同轴数据。
确定同轴数据在图像帧的消隐区的第三位置时，可以包括：将图像帧的消隐区中的第三预设位置确定为同轴数据的第三位置。例如，可以将消隐区中预设的第2行到第4行的位置确定为第三位置。在另一种实施方式中，消隐区中还可以包括服务器向模拟摄像机发送的同轴数据的位置，该位置可以为消隐区中不同于第三位置的位置。
消隐区包括场消隐区和行消隐区。第三位置可以位于场消隐区，也可以位于行消隐区，也可以一部分在场消隐区，另一部分在行消隐区。在一种具体实施方式中，场消隐区的可存储数据量大于行消隐区的可存储数据量，因此可以从场消隐区中确定第三位置，以提高可存储的同轴数据的数据量。
当第二位置不是固定位置时，获取待发送的同轴数据的步骤，可以包括：获取待发送的包括表示第二位置的数据的同轴数据。
由于同轴数据的第三位置可以为固定位置，服务器和模拟摄像机可以预先约定第三位置，从而在服务器获取同轴数据时，可以按照约定的第三位置获取。在获取同轴数据之后，可以根据同轴数据中包括的表示第二位置的数据，确定第二位置，从第二位置中获取目标数据，提高获取目标数据时的准确性。
在本实施例中，同轴数据还可以包括除了表示第二位置的数据之外的其他数据，本申请对此不作具体限定。
步骤2：将同轴数据作为与视频流数据和目标数据所在图像帧的数据，采用消隐区的数据发送方式，按照第三位置发送同轴数据。
作为一个例子，图9a为图像帧的有效图像区和消隐区所对应的数据的一 种示意图。其中，中间实现矩形框区为有效图像区，有效图像区由虚线分割成两部分，其中一部分为视频流数据的位置所在区域，另一部分为目标数据的位置所在区域。有效图像区之外的部分为消隐区，消隐区为同轴数据的位置所在区域。
作为一个例子，图9b为模拟摄像机向服务器发送图像帧的一种传输架构图。其中，一个图像帧中包括视频流数据、同轴数据和目标数据。
可见，本实施例可以获取同轴数据，将视频流数据、目标数据和同轴数据作为同一图像帧的数据发送至服务器，使服务器通过同一图像帧接收待发送视频流数据、目标数据和同轴数据，提高数据传输效率。
在上述实施例的一种具体实施方式中，表示第二位置的数据在图像帧的消隐区中的位置，可以位于第二位置之前。
本实施例具体可以为，第三位置位于第二位置之前，这样可以保证表示第二位置的数据在图像帧的消隐区的位置位于第二位置之前。
例如，在图9a中，同轴数据可以位于有效图像区上方的消隐区中，这样表示第二位置的数据在图像帧的消隐区中的位置位于有效图像区中第二位置之前。
如果服务器在接收图像帧携带的数据时，按照从前向后的数据获取方式获取数据，则使表示第二位置的数据在图像帧的消隐区中的位置位于第二位置之前，能够使服务器先获取同轴数据中表示第二位置的数据，然后可以根据该表示第二位置的数据从有效图像区中获取目标数据，从而提高获取目标数据的效率。
在相关技术中，视频流数据可以以模拟信号的方式叠加在有效图像区，而同轴数据可以以数字信号的方式叠加在消隐区。每种规格的分辨率图像均存在其对应的传输参数，较高分辨率的图像可以使用较高的传输参数。传输参数可以为2MP30，该参数可以理解为每秒传输30帧200万像素的图像。在本实施例中，可以使用更高规格的传输参数来传输较低分辨率的图像，例如可以使用4MP30的传输参数来传输原来可以用2MP30的传输参数来传输的图像帧。这样，图像帧的有效图像区会存在大片的闲置区，这些闲置区可以用来 传输目标数据。
在本实施例中，同轴数据仍然保持原来的传输方式不变，而视频流数据占用有效图像区的一部分区域，目标数据占用有效图像区的另一部分区域。模拟摄像机可以与服务器约定目标数据在图像帧中的存储位置。或者，也可以将目标数据在图像帧中的存储位置放置在同轴数据中。服务器可以比较容易地从同轴数据中解析出该存储位置。
本实施例提供的数据传输方式，可以使每一图像帧均存在相应的目标数据，因此数据的实时性和同步性较好，可存储的数据量也比较大。本实施例也不限制传输材料，传输材料可以为同轴线缆、双绞线或其他材料，无需另外布线，减少了设备成本。
本申请实施例还提供了第三种数据传输方法，以传输上述转换后的混合数据。下面通过具体实施例，对第三种数据传输方法进行详细说明。如图10所示，该方法包括如下步骤：S1001～S1002：
S1001：确定视频流数据在图像帧的有效图像区中的第一位置，以及确定目标数据在图像帧的消隐区中的第二位置，所述目标数据包括所述目标的属性和/或位置信息。
其中，目标数据为不同于视频流数据和同轴数据的数据。同轴数据为服务器和模拟摄像机之间交互的通知信息，该同轴数据也可以称为PTZ数据。当模拟摄像机和服务器分别为视频生成端和视频接收端时，视频生成端和视频接收端之间交互的同轴数据可以包括视频生成端向视频接收端发送的同轴发送数据，也可以包括视频接收端向视频生成端发送的同轴接收数据。例如，视频接收端为硬盘录像机(Digital Video Recorder，DVR)时，同轴数据可以包括模拟摄像机向DVR发送的拍摄模式信息、升级时准备就绪的信息等，也可以包括模拟摄像机与DVR之间的握手数据，该握手数据可以用于发送表示设备类型、图像分辨率的数据等。同轴数据还可以包括DVR向模拟摄像机发送的控制信息等，该控制信息可以包括针对摄像机的控制指令，例如图像参数调节指令、摄像机光圈调节指令、摄像机旋转调节指令、分辨率切换指令、 远程升级数据指令等。同轴数据还可以包括视频流数据在图像帧中的位置以及目标数据在图像帧中的位置等信息。
图像帧中可以包括同轴数据，也可以不包括同轴数据。
S1002：将视频流数据以及目标数据作为同一图像帧的数据，采用有效图像区的数据发送方式，按照第一位置发送视频流数据，以及采用消隐区的数据发送方式，按照第二位置发送目标数据。
上述“转换后的混合数据”包括视频流数据和目标数据，因此，通过S1001和S1002，实现了对“转换后的混合数据”的发送。
在S1001中，确定视频流数据在图像帧的有效图像区中的第一位置时，可以将第一预设位置确定为视频流数据在图像帧的有效图像区中的第一位置，预设位置包括起始位置和末尾位置。也可以根据视频流数据的数据量，确定视频流数据在图像帧的有效图像区中的第一位置。
根据视频流数据的数据量，确定视频流数据在图像帧的有效图像区中的第一位置时，具体可以为，将视频流数据在图像帧的有效图像区中的第一位置确定为：从第一预设初始位置开始，到第一末尾位置；其中，第一末尾位置为：第一预设初始位置加视频流数据的数据量后得到的位置。第一预设初始位置和第一末尾位置均位于有效图像区。
在S1001中，确定目标数据在图像帧的消隐区中的第二位置时，可以将第二预设位置确定为目标数据在图像帧的消隐区中的第二位置。也可以根据目标数据的数据量，确定目标数据在图像帧的消隐区中的第二位置。
根据目标数据的数据量，确定目标数据在图像帧的消隐区中的第二位置时，具体可以为，将目标数据在图像帧的消隐区中的第二位置确定为：从第二预设初始位置开始，到第二末尾位置；其中，第二末尾位置为：第二预设初始位置加目标数据的数据量后得到的位置。第二预设初始位置和第二末尾位置均位于消隐区。
上述第二位置可以是图像帧消隐区的固定位置，也可以是不固定的位置。消隐区中同轴数据的位置是固定位置，因此目标数据在消隐区的第二位置可以是消隐区中除同轴数据的位置之外的位置。例如，第二位置可以为消隐区 中除同轴数据的位置之外的部分区域的位置，也可以为消隐区中除同轴数据的位置之外的全部区域的位置，本申请对此不做具体限定。
消隐区包括场消隐区和行消隐区。第二位置可以位于场消隐区，也可以位于行消隐区，也可以一部分在场消隐区，另一部分在行消隐区。在一种具体实施方式中，场消隐区的可存储数据量大于行消隐区的可存储数据量，因此可以从场消隐区中确定第二位置，以提高可存储的目标数据的数据量。
在一种具体实施方式中，同轴数据和目标数据的位置均可以在场消隐区中。例如，已知1920*1080图像帧的场消隐区包含36行。同轴数据的数据量一般很小，为字节级别的数据量，可以为同轴数据分配场消隐区的2～4行，剩余的32行可以分配给目标数据，因此消隐区可存储的目标数据的数据量大概在几百个字节数量级别。
为了提高消隐区的可存储数据量，可以提高传输的图像帧的规格。例如，从200万像素的图像帧提高到300万像素的图像帧。
当第二位置为固定的位置时，服务器和模拟摄像机可以预先约定第二位置，从而使服务器可以按照约定的第二位置获取目标数据，提高获取目标数据时的准确性。
当第二位置为不固定的位置时，目标数据可以包括表示目标数据的起始位置的头标识，以及表示目标数据的末尾位置的尾标识。这样，当服务器在获取目标数据时，可以根据上述头标识确定目标数据的起始位置，根据上述尾标识确定目标数据的末尾位置，根据确定的目标数据的起始位置和目标数据的末尾位置，从消隐区获取目标数据，从而在第二位置不固定时能够准确地获取目标数据。这种实施方式中目标数据发送时的灵活性比较大。
其中，头标识可以为第一预设比特串，尾标识可以为第二预设比特串。目标数据的前第一预设数量个比特位可以为第一预设比特串，目标数据的后第二预设数量个比特位可以为第二预设比特串。
在发送上述图像帧时，可以将图像帧中的数据逐行地以数据流的形式进行发送，也可以将图像帧中的数据逐列地以数据流的形式进行发送。
服务器在接收到模拟摄像机发送的图像帧时，可以按照预设的数据存储 规则，对图像帧进行解析，获得图像帧中的视频流数据和目标数据。
由上述内容可知，本实施例确定视频流数据在图像帧的有效图像区中的第一位置，以及确定目标数据在图像帧的消隐区中的第二位置，将视频流数据以及目标数据作为同一图像帧的数据，采用有效图像区的数据发送方式，按照第一位置发送视频流数据，以及采用消隐区的数据发送方式，按照第二位置发送目标数据。因此，本申请实施例可以实现将上述“转换后的混合数据”以同一图像帧发送至电子设备，无需另外布线，能够节省设备成本。
在模拟摄像机向服务器发送的大量图像帧中，可以在所有图像帧中均携带目标数据，也可以在部分图像帧中携带目标数据。当获取到目标数据时，可以将有效图像区携带视频流数据、消隐区携带目标数据的图像帧发送至服务器。当没有获取到目标数据时，可以将有效图像区携带视频流数据、消隐区不携带目标数据的图像帧发送至服务器。
在本申请的另一实施例中，在发送视频流数据和目标数据之前，该方法还可以包括以下步骤1～步骤2：
步骤1：获取待发送的同轴数据，以及确定同轴数据在图像帧的消隐区的第三位置。
本实施例中，图像帧中包括视频流数据、目标数据和同轴数据。
确定同轴数据在图像帧的消隐区的第三位置时，可以包括：将第三预设位置确定为同轴数据在图像帧的消隐区中的第三位置。例如，可以将消隐区中预设的第2行到第4行的位置确定为第三位置。在另一种实施方式中，消隐区中还可以包括服务器向模拟摄像机发送的同轴数据的位置，该位置可以为消隐区中不同于第三位置的位置。
在消隐区中，第三位置可以在第二位置之前，也可以在第二位置之后。由于场消隐区的数据量远大于行消隐区的数据量，可以从场消隐区确定第三位置。
当第二位置不是固定位置时，获取待发送的同轴数据的步骤，可以包括：获取待发送的包括表示第二位置的数据的同轴数据。
由于同轴数据的第三位置可以为固定位置，服务器和模拟摄像机可以预先约定第三位置，从而在服务器获取同轴数据时，可以按照约定的第三位置获取。在获取同轴数据之后，可以根据同轴数据中包括的表示第二位置的数据，确定第二位置，从第二位置中获取目标数据，提高获取目标数据时的准确性。
在本实施例中，同轴数据还可以包括除了表示第二位置的数据之外的其他数据，本申请对此不作具体限定。
步骤2：将同轴数据作为与视频流数据和目标数据所在图像帧的数据，采用消隐区的数据发送方式，按照第三位置发送同轴数据。
作为一个例子，图11a为图像帧的有效图像区和消隐区所对应的数据的一种示意图。其中，竖线阴影区为有效图像区，竖线阴影区之外的空白区为消隐区。有效图像区上下方的消隐区为场消隐区，有效图像区左右两侧的消隐区为行消隐区。在图11a所示例子中，同轴数据的存储位置位于上方的场消隐区，目标数据的存储位置位于下方的场消隐区。
作为一个例子，图9b为模拟摄像机向服务器发送图像帧的一种传输架构图。其中，一个图像帧中包括视频流数据、同轴数据和目标数据。
可见，本实施例可以获取同轴数据，将视频流数据、目标数据和同轴数据作为同一图像帧的数据发送至服务器，使服务器通过同一图像帧接收视频流数据、目标数据和同轴数据，提高数据传输效率。
在上述实施例的一种具体实施方式中，表示第二位置的数据在图像帧的消隐区中的位置，可以位于第二位置之前。
本实施例具体可以为，第三位置位于第二位置之前，这样可以保证表示第二位置的数据在图像帧的消隐区的位置位于第二位置之前。
如果服务器在接收图像帧携带的数据时，按照从前向后的数据获取方式获取数据，则使表示第二位置的数据在图像帧的消隐区中的位置位于第二位置之前，能够使服务器先获取同轴数据中表示第二位置的数据，然后可以根据该表示第二位置的数据从消隐区中获取目标数据，从而提高获取目标数据的效率。
在相关技术中，视频流数据可以以模拟信号的方式叠加在有效图像区，而同轴数据可以以数字信号的方式叠加在消隐区。同轴数据的数据量很小，大概为字节级别(可以为6～24个字节)，因此还有大量空闲的消隐区可以用于存储目标数据。在本实施例中，可以将目标数据存储在闲置的消隐区中。
在本实施例中，视频流数据和同轴数据仍然保持原来的传输方式不变，将未曾使用的一些消隐区用于填充目标数据。模拟摄像机可以与服务器约定目标数据在图像帧中的存储位置。或者，也可以将目标数据在图像帧中的存储位置放置在同轴数据中。服务器可以比较容易地从同轴数据中解析出该存储位置。
本实施例提供的数据传输方式，可以使每一图像帧均存在相应的目标数据，因此数据的实时性和同步性较好。本实施例也不限制传输材料，传输材料可以为同轴线缆、双绞线或其他材料，无需另外布线，减少了设备成本。
本申请实施例还提供一种应用于服务器侧的数据处理方法，该服务器与模拟摄像机相连接。下面通过具体实施例，对该数据处理方法进行详细说明。
图12为本申请实施例提供的应用于服务器侧的数据处理方法的第一种流程示意图，包括：
S1201：接收待处理模拟摄像机发送的数据。
在本实施例中，为了方便描述，将向服务器发送数据的模拟摄像机称为待处理模拟摄像机。
S1202：从所接收到的数据中分离得到视频流数据及图像分析数据。
服务器与模拟摄像机可以预先约定视频流数据及图像分析数据的叠加方式及分离方式，比如，如果模拟摄像机在视频流数据的消隐区中叠加图像分析数据，服务器则在消隐区中读取图像分析数据。
具体来说，服务器可以根据消隐区标识，在所接收到的数据中确定消隐区和图像区；读取所述消隐区中的数据，提取图像分析数据；读取所述图像区中的数据，提取视频流数据。
或者，模拟摄像机与服务器也可以约定第几行为视频流数据，第几行为图像分析数据，这样，服务器也可以从所接收到的数据中分离得到视频流数据及图像分析数据，具体分离方式不做限定。
S1203：对分离得到的视频流数据及所述图像分析数据分别进行处理。
服务器分离得到视频流数据及图像分析数据后，对这两种数据分别进行处理。比如，对视频流数据可以进行编码、存储等处理，具体不做限定。
图像分析数据为模拟摄像机对采集到的图像进行分析后得到的数据。作为一种实施方式，图像分析数据中可以包含目标的属性和/或位置信息，所述目标为所述视频流数据中存在的目标。这种实施方式中，对分离得到图像分析数据后，可以在图像分析数据中读取目标的属性和/或位置信息，所述目标为所述视频流数据中存在的目标。
图像分析数据中还可以包含其他内容，比如携带有所述目标的图像等，具体不做限定。
举例来说，模拟摄像机可以对图像进行人脸识别，将识别出的人脸特征作为图像分析数据发送给服务器。服务器分离得到人脸特征后，可以将该人脸特征与数据库中存储的人脸特征进行对比，进而确定出该人脸对应的身份信息。
或者，模拟摄像机对图像进行人脸识别后，确定人脸在图像中的位置信息，将该位置信息作为图像分析数据发送给服务器。服务器分离得到该位置信息后，可以通过该位置信息直接在图像中获取到人脸区域。
再举一例，模拟摄像机可以对图像进行车牌识别，将识别出的车牌号作为图像分析数据发送给服务器。服务器分离得到该车牌号后，可以确定该车牌号对应的车主信息，或者，在数据库中查找该车牌号对应的行驶轨迹等。
或者，模拟摄像机对图像进行车牌识别后，确定车牌在图像中的位置信息，将该位置信息作为图像分析数据发送给服务器。服务器分离得到该位置信息后，可以通过该位置信息直接在图像中获取到车牌区域。
服务器对视频流数据及图像分析数据的处理方式有多种，可以根据实际 情况进行设定，具体不做限定。
作为一种实施方式，具有图像分析功能的模拟摄像机在发送视频流数据及图像分析数据时，可以采用多种不同的发送方式，比如：一、将视频流数据、图像分析数据都转换为模拟数据进行发送；二、仅将视频流数据转换为模拟数据，发送模拟视频流数据、以及数字图像分析数据；三、将视频流数据转换为模拟数据，将图像分析数据转换为低频数字数据，发送模拟视频流数据、以及该低频数字数据，等等，具体发送方式不做限定。
如果为第一种发送方式，则服务器接收到的数据为模拟数据，服务器可以对所接收到的数据进行模数转换，得到转换后的数字数据；从所述转换后的数字数据中分离得到数字视频流数据及数字图像分析数据。或者，服务器也可以从所接收到的数据中分离得到模拟视频流数据及模拟图像分析数据；将所述模拟视频流数据及模拟图像分析数据进行模数转换，得到数字视频流数据及数字图像分析数据。
如果为第二种发送方式，则服务器从所接收到的数据中分离得到模拟视频流数据及数字图像分析数据；将所述模拟视频流数据进行模数转换，得到数字视频流数据。
如果为第三种发送方式，则服务器从所接收到的数据中分离得到模拟视频流数据及数字图像分析数据；将所述模拟视频流数据进行模数转换，得到数字视频流数据；对所述数字图像分析数据进行低频采样，得到预设格式的数据，并对所述预设格式的数据进行标记。
该预设格式可以为BT1120格式，或者也可以为其他格式，具体不做限定。可以对预设格式的数据进行标记，也可以对数字视频流数据进行标记，以便在后续处理过程中，对这两种数字数据进行区分。
图13为本申请实施例提供的应用于服务器侧的数据处理方法的第二种流程示意图，包括：
S1301：接收待处理模拟摄像机发送的数据。
在本实施例中，为了方便描述，将向服务器发送数据的模拟摄像机称为待处理模拟摄像机。该待处理模拟摄像机可以为具有图像分析功能的设备， 也可以为不具有图像分析功能的设备。
S1302：判断该待处理模拟摄像机是否具有图像分析功能；如果是，执行S1303，如果否，执行S1304。
在本申请实施例中，服务器中存在两类模式：第一类处理模式和第二类处理模式。其中，第一类处理模式用于处理具有图像分析功能的模拟摄像机发送的数据，第二类处理模式用于处理不具有图像分析功能的模拟摄像机发送的数据。
不具有图像分析功能的模拟摄像机发送的数据中仅包含采集的视频流数据，不包含图像分析数据；而具有图像分析功能的模拟摄像机发送的数据中既包含采集的视频流数据，又包含图像分析数据。因此，第一类处理模式可以理解为：针对S1301接收到的数据中包含视频流数据及图像分析数据的情况进行处理的模式，第二类处理模式可以理解为：针对S1301接收到的数据中不包含图像分析数据的情况进行处理的模式。
S1303：触发第一类处理模式：从所接收到的数据中分离得到视频流数据及图像分析数据；对分离得到的视频流数据及所述图像分析数据分别进行处理。

该预设格式可以为BT1120格式，或者也可以为其他格式，具体不做限定。可以对预设格式的数据进行标记，也可以对数字视频流数据进行标记，以便在后续处理过程中，对这两种数字数据进行区分。
S1304：触发第二类处理模式：对接收到的视频流数据进行分析，得到图像分析数据；对接收到的视频流数据、以及分析得到的图像分析数据分别进行处理。

图14为本申请实施例提供的应用于服务器侧的数据处理方法的第三种流程示意图，包括：
S1401：向系统中的模拟摄像机发送属性请求指令，并接收系统中的模拟摄像机反馈的设备属性。
S1402：对接收到的模拟摄像机反馈的设备属性进行记录。

在图14所示实施例中，服务器可以向系统中模拟摄像机发送属性请求指令，也可以仅在检测到系统中接入新的模拟摄像机后，向该新的模拟摄像机发送属性请求指令。
模拟摄像机接收到该属性请求指令后，将自身设备属性发送给服务器。举例来说，该设备属性可以包括：设备型号、或者设备硬件性能等，服务器可以根据设备型号、或者设备硬件性能，判断该模拟摄像机是否具有图像分析功能，如果具有，则触发第一类处理模式，如果不具有，则触发第二类处理模式。
再举一例，该设备属性也可以包括能够直接反应模拟摄像机是否具有图像分析功能的信息，服务器可以直接根据该信息，判断该模拟摄像机是否具有图像分析功能，如果具有，则触发第一类处理模式，如果不具有，则触发第二类处理模式。
再举一例，该设备属性也可以包括模拟摄像机的名称、或ID等，服务器中存储有模拟摄像机的名称或ID对应的设备功能信息，服务器可以根据该模拟摄像机的名称或ID，判断该模拟摄像机是否具有图像分析功能，如果具有，则触发第一类处理模式，如果不具有，则触发第二类处理模式。
应用本申请图14所示实施例，服务器预先获取系统中模拟摄像机的设备属性，根据设备属性判断模拟摄像机是否具有图像分析功能，针对功能不同的模拟摄像机采用不同的处理模式，应用本方案，服务器既能够对具有图像分析功能的模拟摄像机发送的数据进行处理，也能够对不具有图像分析功能的模拟摄像机发送的数据进行处理，解决了系统的不兼容问题。
本申请实施例还提供了一种监控系统，如图15所示，包括模拟摄像机10和服务器20，其中，
模拟摄像机10包括：图像采集芯片100、图像分析芯片200、集成芯片300和发送芯片400，图像采集芯片100分别与图像分析芯片200、集成芯片300相连接，图像分析芯片200与集成芯片300相连接，发送芯片400与集成芯片300相连接；
图像采集芯片100，用于采集数字视频流数据；
图像分析芯片200，用于对所述数字视频流数据进行分析，识别所述数字视频流数据中存在的目标，提取所述目标的属性和/或位置信息，作为图像分析数据；并将所述图像分析数据发送到集成芯片300；
集成芯片300，用于根据预设插入模式，将所述图像分析数据插入至所述数字视频流数据中，得到混合数据，并将所述混合数据发送到发送芯片400；
发送芯片400，用于将所述混合数据、或者所述混合数据中的数字视频流数据转换为模拟数据，得到转换后的混合数据；将所述转换后的混合数据发送到服务器20；
服务器20，用于接收所述混合数据，根据所述预设插入模式对应的分离模式，将所述混合数据分离为视频流数据和图像分析数据。
本申请实施例提供的监控系统中的模拟摄像机可以为本申请实施例提供的任一种模拟摄像机，不再赘述。
在上述模拟摄像机的各种实施方式中，集成芯片300在数字视频流数据中插入的数据或有不同，比如，一些实施方式中，仅插入目标的属性和/或位置信息；在另一些实施方式中，插入目标的属性和/或位置信息、以及抓取的图像；在另一些实施方式中，插入目标的属性和/或位置信息、以及压缩后的图像；为了方便描述，将这些插入的数据都称为图像分析数据。
服务器20与模拟摄像机10可以预先约定视频流数据及图像分析数据的叠加方式(插入模式)及分离方式，比如，如果模拟摄像机10在数字视频流数据的消隐区中叠加图像分析数据，服务器20则在消隐区中读取图像分析数据。
具体来说，服务器20可以根据消隐区标识，在所接收到的数据中确定消隐区和图像区；读取所述消隐区中的数据，作为图像分析数据；读取所述图像区中的数据，作为视频流数据。
或者，模拟摄像机10与服务器20也可以约定第几行为视频流数据，第几行为图像分析数据，这样，服务器20也可以从所接收到的数据中分离得到视频流数据及图像分析数据，具体分离方式不做限定。
服务器20分离得到视频流数据及图像分析数据后，对这两种数据分别进行处理。比如，对视频流数据可以进行编码、存储等处理，具体不做限定。
举例来说，假设服务器20分离得到的图像分析数据中包含人脸特征，则服务器20可以将该人脸特征与数据库中存储的人脸特征进行对比，进而确定出该人脸对应的身份信息。
再举一例，假设服务器20分离得到的图像分析数据中包含车牌号，则服务器20可以确定该车牌号对应的车主信息，或者，在数据库中查找该车牌号对应的行驶轨迹等。
再举一例，假设服务器20分离得到的图像分析数据中包含图像、以及人 脸在该图像中的位置信息，则服务器可以根据该位置信息，在该图像中确定出人脸区域，服务器可以将该人脸区域发送给显示设备进行显示。或者，服务器也可以在确定出人脸区域后，提取人脸特征等。
服务器20对视频流数据及图像分析数据的处理方式有多种，可以根据实际情况进行设定，具体不做限定。
可见，在本实施例中，模拟摄像机将图像分析数据发送给服务器，服务器根据该图像分析数据，直接得到目标的关联信息，比如，属性、位置信息、图像等，服务器不需要在图像中进行目标识别，减少了服务器的运算量。
在一种实施方式中，发送芯片400可以将混合数据中的数字视频流数据转换为模拟视频流数据；将混合数据中的图像分析数据转换为低频数字数据；将该模拟视频流数据及该低频数字数据发送到服务器20。
这种情况下，服务器20可以对分离得到的视频流数据进行模数转换，得到第一数字数据；对分离得到的图像分析数据进行低频采样，得到第二数字数据。然后服务器20再对第一数字数据和第二数字数据分别进行处理。
分离过程与转换过程可以同时进行，比如，服务器20根据与模拟摄像机10的约定，确定读取的数据为视频流数据，则可以对读取的数据进行模数转换；服务器20根据与模拟摄像机10的约定，确定读取的数据为图像分析数据，则可以对读取的数据进行低频采样。
或者，也可以先进行分离过程，再进行转换过程，具体不做限定。
在另一种实施方式中，发送芯片400将混合数据转换为模拟混合数据，将模拟混合数据发送到服务器20。这种情况下，服务器20可以先将接收到的混合数据分离为视频流数据和图像分析数据，再对分离得到的视频流数据和图像分析数据都进行模数转换，得到数字数据。或者，服务器也可以先进行模数转换，得到数字混合数据，再对数字混合数据进行分离，得到数字视频流数据和图像分析数据。或者，也可以同时进行分离过程与模数转换过程，具体不做限定。
作为一种实施方式，服务器20可以将数字视频流数据、图像分析数据均转换为预设格式的数据，比如BT656格式的数据等，具体不做限定。
为了方便描述，本实施例中，将视频流数据转换的数字数据称为第一数字数据，将图像分析数据转换的数字数据称为第二数字数据。作为一种实施方式，服务器20可以对第一数字数据和/或第二数字数据进行标记，以便在后续处理过程中，对这两种数字数据进行区分。
具体的标记方式不做限定，比如，可以在数据头部增加特殊标记位等，如果第一数字数据与第二数字数据都进行标记，则标记方式不同。
作为一种实施方式，模拟摄像机10与服务器20可以通过同轴线缆相连接，或者，也可以通过其他方式通信连接，比如，通过双绞线相连接、或者无线连接等，具体不做限定。
应用本申请实施例提供的模拟摄像机，模拟摄像机中包含图像分析芯片，该图像分析芯片对采集到的数字视频流数据进行分析，识别数字视频流数据中存在的目标，提取目标的属性和/或位置信息；并将目标的属性和/或位置信息发送到集成芯片，集成芯片根据预设插入模式，将目标的属性和/或位置信息插入至数字视频流数据中，得到混合数据；可见，本方案中的模拟摄像机实现了对采集到的图像进行分析处理。
应用本申请实施例提供的监控系统，模拟摄像机将图像分析数据发送给服务器，服务器根据该图像分析数据，直接得到目标的关联信息，比如，属性、位置信息、图像等，服务器不需要在图像中进行目标识别，减少了服务器的运算量。
图16为本申请实施例提供的一种服务器的结构示意图，包括：
传感信号接收芯片110、图像信号接收芯片120和信号处理芯片130，传感信号接收芯片110及图像信号接收芯片120分别与信号处理芯片130相连接；
传感信号接收芯片110，用于接收无线传感器发送的传感信号，并将传感信号发送至信号处理芯片130；
图像信号接收芯片120，用于接收模拟摄像机发送的图像信号，并将图像 信号发送至信号处理芯片130；
信号处理芯片130，用于对传感信号及图像信号进行关联处理。
应用本申请图16所示实施例，服务器中的传感信号接收芯片接收无线传感器发送的传感信号，图像信号接收芯片接收模拟摄像机发送的图像信号，信号处理芯片对该传感信号及该图像信号进行关联处理；可见，本方案中的服务器实现了将同一场景中的传感信号及该图像信号进行关联处理。
传感信号接收芯片预先与一个或多个无线传感器进行配对连接，这样，传感信号接收芯片便可以接收并处理无线传感器发射的传感信号。作为一种实施方式，服务器中可以包含多个传感信号接收芯片，每个传感信号接收芯片分别与一个无线传感器进行配对连接；或者，作为另一种实施方式，服务器中可以包含一个传感信号接收芯片，该传感信号接收芯片与一个或多个无线传感器配对连接。
作为一种实施方式，如图17所示，传感信号接收芯片110包括电磁接收天线1101和处理器1102，电磁接收天线1101，用于接收无线发射传感器发射的电磁波形式的传感信号，并将该电磁波形式的传感信号发送至处理器1102；处理器1102，用于将该电磁波形式的传感信号转换为电信号形式的传感信号。
可以理解，无线传感器一般以电磁波的形式发送传感信号，传感信号接收芯片110接收到该电磁波后，需要将该电磁波转换为自身可处理的电信号。
作为一种实施方式，如图18所示，传感信号接收芯片110包括电磁接收天线1101、处理器1102和分类器1103，电磁接收天线1101，用于接收无线发射传感器发射的电磁波形式的传感信号，并将该电磁波形式的传感信号发送至处理器1102；处理器1102，用于将该电磁波形式的传感信号转换为电信号形式的传感信号；分类器1103，用于接收处理器1102发送的电信号形式的传感信号，确定该电信号形式的传感信号的类别信息，将该电信号形式的传感信号及该类别信息发送到信号处理芯片130。
本申请实施例中的无线传感器可以包括以下任意一种或多种：门磁传感器、红外探测器、烟雾传感器、温度传感器、湿度传感器，或者，也可以为其他，具体不做限定。不同类别的无线传感器，采集不同类别的环境信息， 比如，门磁传感器可以采集门磁与磁体之间是否发生位移的信息，红外探测器可以采集预设区域中是否存在人员的信息，烟雾传感器可以采集环境中的烟雾信息，温度传感器可以采集环境中的温度信息，湿度传感器可以采集环境中的湿度信息，等等，不再一一列举。
相对应的，这些不同类别的无线传感器将采集到的各类别的环境信息转换为不同类别的传感信号，比如，门磁传感器将门磁与磁体之间是否发生位移的信息转换为门磁传感信号，红外探测器将预设区域中是否存在人员的信息转换为红外传感信号，烟雾传感器将环境中的烟雾信息转换为烟雾传感信号，温度传感器将环境中的温度信息转换为温度传感信号，湿度传感器将环境中的湿度信息转换为湿度传感信号，等等，不再一一列举。
对于服务器来说，可以对不同类别的传感信号进行分类处理。图18中的分类器1103即可以对处理器1102发送的传感信号进行分类标记，也就是确定传感信号的类别信息，并将该类别信息与传感信号一并发送至信号处理芯片130。
如果信号处理芯片130接收到的图像信号为模拟信号，则信号处理芯片130先将该图像信号进行模数转换，得到数字图像信号，再将该数字图像信号进行格式转换，得到预设格式的数字图像信号。举例来说，可以将该数字图像信号转换为标准并行数据格式后，再将其与传感信号进行关联处理。
信号处理芯片130对传感信号及图像信号进行关联处理，举例来说，假设信号处理芯片130对图像信号进行分析，分析结果表示当前场景中存在一个模糊的目标，但仅根据图像信号并不能确定该目标是人体还是物体；此外，信号处理芯片130接收到红外探测器发送的红外传感信号，对该红外传感信号进行分析，分析结果表示当前场景中存在一个人体目标；信号处理芯片130可以对图像信号分析结果中的模糊目标与传感信号分析结果中的人体目标进行位置匹配，如果匹配成功，表示图像信号分析结果中的模糊目标为一人体。这样，信号处理芯片130实现了对传感信号及图像信号的关联处理。
再举一例，假设场景中发生火灾，同时存在较大烟雾，由于烟雾影响，模拟摄像机采集到的图像信号画面内容不清楚，信号处理芯片130对图像信号进行分析，仅根据图像信号的分析结果，只能判断场景中失火了，并不能判 断当前火势大小；此外，信号处理芯片130接收到温度传感器发送的温度传感信号，对该温度传感信号进行分析，得到当前场景中的环境温度；信号处理芯片130结合图像信号分析结果、温度传感信号分析结果，可以较准确地对火势大小进行判断。
再举一例，假设信号处理芯片130接收到烟雾传感器发送的烟雾传感信号，对该烟雾传感信号进行分析，分析结果表示当前场景中存在烟雾，但仅根据烟雾传感信号并不能确定场景中有人吸烟还是场景中有火灾；此外，信号处理芯片130接收到图像信号，对该图像信号进行分析，分析结果表示当前场景中不存在火灾，而存在一个在吸烟的人体目标；信号处理芯片130结合图像信号分析结果、温度传感信号分析结果，可以确定并未发生火灾，只是一个人在吸烟。
作为一种实施方式，如图19所示，服务器中还可以包括显示器140，显示器140与信号处理芯片130相连接。或者，也可以在图17、图18的基础上增加显示器140，具体不做限定。
在本实施方式中，信号处理芯片140对传感信号及图像信号进行关联处理后，将关联处理结果发送至显示器140，显示器140对接收到的关联处理结果进行显示。
比如，上述例子中，信号处理芯片130对图像信号分析结果中的模糊目标与传感信号分析结果中的人体目标进行位置匹配，如果匹配成功，则关联处理结果可以为：某某区域内有人员进入，或者类似的信息；信号处理芯片130将该关联处理结果发送至显示器140进行显示。
再比如，上述例子中，信号处理芯片130结合图像信号分析结果、温度传感信号分析结果，判断当前火势大小，则关联处理结果可以为当前火势等级；信号处理芯片130将该关联处理结果发送至显示器140进行显示。
再比如，上述例子中，信号处理芯片130结合图像信号分析结果、温度传感信号分析结果，确定一个人在吸烟，则关联处理结果可以为提示禁止吸烟的信息，或者类似的信息；信号处理芯片130将该关联处理结果发送至显示器140进行显示。
作为一种实施方式，如图20所示，服务器中还可以包括报警器150，报警器150与信号处理芯片130相连接。在本实施方式中，信息处理芯片130，还可以用于根据关联处理结果，控制报警器150进行报警。或者，也可以在图17、图18、图19的基础上增加报警器150，具体不做限定。
该报警器可以为闪烁灯、蜂鸣器等，相对应的，报警方式可以为灯光闪烁、蜂鸣声等，具体不做限定。
服务器中可以预先存储报警条件，比如，当指定区域内有人员进入时进行报警，或者，当场景中有火情时进行报警，或者，当场景中有人吸烟时进行报警，等等。信息处理芯片130根据上述关联处理结果，判断是否符合预先存储的报警条件，如果符合，控制报警器150进行报警。
或者，报警器也可以为一台独立的设备，报警器与服务器通信连接，信息处理芯片130根据关联处理结果，判断是否符合报警条件，如果符合，向报警器发送报警信息，报警器接收到报警信息后进行报警。
或者，报警器也可以与该模拟摄像机一体设置，信息处理芯片130根据关联处理结果，判断是否符合报警条件，如果符合，向该模拟摄像机发送报警信息，该模拟摄像机接收到报警信息后控制报警器进行报警。
或者，报警器也可以与该无线传感器一体设置，信息处理芯片130根据关联处理结果，判断是否符合报警条件，如果符合，向该无线传感器发送报警信息，该无线传感器接收到报警信息后控制报警器进行报警。
应用本申请图16所示实施例，服务器中的传感信号接收芯片接收无线传感器发送的传感信号，图像信号接收芯片接收模拟摄像机发送的图像信号，信号处理芯片对该传感信号及该图像信号进行关联处理；可见，本方案中的服务器实现了将同一场景中的传感信号及该图像信号进行关联处理。

存储器2102，用于存放计算机程序；
