图2是本申请实施例的一种车内环境监控的终端的结构示意图；
图3示意性地示出了用于执行根据本发明的方法的计算设备的框图；以及
图4示意性地示出了用于保持或者携带实现根据本发明的方法的程序代码的存储单元。
具体实施例
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请中的附图，对本申请中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
本申请的主要思想在于，近年来发生多起将儿童或宠物遗留车内造成风险的事例，究其原因，一部分是因为大人的疏忽，在离开车辆之后没有好好观察车内是否遗留儿童或宠物，还有一部分原因就是在车主离开车辆之后无法获知车内是否遗留儿童或宠物，即使车内遗留了儿童或宠物车主也无法获知这一情况，如果在车主离开车辆之后，通过车内设备检测车内是否存有活体，在检测出车内遗留了儿童或宠物能够及时通知车主，以便车主及时做出措施，这样就可以防止将儿童或宠物遗留车内造成安全隐患。
以下将配合附图及实施例来详细说明本申请的实施方式，藉此对本申请如何应用技术手段来解决技术问题并达成技术功效的实现过程能充分理解并据以实施。

图1是本申请实施例的一种车内环境监控的方法的流程示意图，如图1所示：
本申请第一方面提供本申请第一方面提供一种车内环境监控的方法，包括：
步骤S101：检测到车辆停止运行，判断车门的操作是否满足预设启动策略；
终端与车辆相连接，通过车辆接口可以获取车辆的运行信息，例如车辆的启动、停止新型，车门的开关门、锁定解锁等操作信息，在检测到车辆停止运行后，通过车辆接口获得的车门操作信息，判断车门的操作是否满足预设的启动策略，本申请实施例中，优选地，判断车门的操作是否满足预设启动策略，进一步包括：判断主驾驶室侧的车门是否连续进行开门、关门以及锁定操作；判断主驾驶室侧的车门连续进行开门、关门以及锁定操作，判断车辆的其他车门是否锁定，通过预设启动策略可以判断车内是否有人，车辆主驾驶室侧的车门连续进行开门、关门以及锁定的操作，可以说明，在主驾驶室的司机已经离开了车内，这时在判断除了主驾驶室侧的车门之外的其他车门是否锁定，当主驾驶侧的车门锁定，其他车门也是锁定的情况下，可以说明车内已经没有人了。
步骤S102：判断车门满足预设启动策略，则启动车内环境监控模式，在预设时间内，获取车辆内当前的环境图像作为初始图像；
通过步骤S101判断车门满足预设启动策略后，判断车内没有人，则终端启动车内环境监控模块，在预设时间内，获取车辆内当前的环境图像作为初始图像，优选地，获取车辆内当前的环境图像作为初始图像，进一步包括：获取主驾驶室侧的车门方向的主驾初始图像；获取副驾驶侧的车门方向的副驾初始图像；获取车辆的全景初始图像，全景初始图像覆盖车辆的后排位置图像和后排车门的图像。终端启动车内环境监控模式后，由于终端的摄像头能够拍摄到的角度有限，不能够将车内每个位置都一次拍摄到，随意需要将摄像头的焦点位置进行调动，将拍摄不到的死角也拍摄到，所以需要分别获取主驾驶室侧，副驾驶侧和车辆其他位置的图像，获取主驾驶室侧的车门方向的主驾驶初始图像，用于检测主驾驶室位置是否 存在活体，获取副驾驶测得车门方向的副驾初始图像，用于检测副驾驶位置是否存在活体，获取车辆的全景初始图像，车辆的全景初始图像能够覆盖车辆的后排位置图像和后排车门的图像，后排位置包括后排车座，车座靠背等位置。
步骤S103：将初始图像与预存的对比图像进行相似度比对，判断相似度是否小于预设相似度阙值，预存的对比图像为在车辆内没有活体情况下，预先获取的车辆内的环境图像；
终端预先在车辆内没有活体的情况下，获取车辆内的环境图像，作为对比图像，获取对比图像可以用户手动进行启动获取并保存，或者在判断车门满足预设启动策略后，获取对比图像并保存，获取对比图像包括：获取主驾驶室侧的车门方向的主驾对比图像；获取副驾驶侧的车门方向的副驾对比图像；获取车辆的全景对比图像。
将通过步骤S102获取的初始图像与对比图像进行相似度比对，判断相似度是否小于预设相似度阙值，本申请优选地，将初始图像与预存的对比图像进行相似度比对，判断相似度是否小于预设相似度阙值，进一步包括：将主驾初始图像与预存的主驾对比图像进行相似度比对；将副驾初始图像与预存的副驾对比图像进行相似度比对；将全景初始图像与预存的全景对比图像进行比对；判断三组相似度比对的结果之中任一一组相似度是否小于预设相似度阙值，对主驾驶初始图像、副驾初始图像以及全景初始图像与其相对应的对比图像进行相似度比对，分别判断三组相似度比对的结果，判断三组相对比对结果中是否小于预设相似度阙值。
步骤S104：当判断初始图像与对比图像的相似度小于预设阙值，则向预设终端发送警报信息，以便预设终端提醒用户车辆内具有活体。
当判断初始图像与对比图像的相似度小于预设阙值，这说明车内存有活体，则向预设的终端发送警报信息，预设的终端接收到警报信息后，终端提醒用户车辆内有活体，预设终端可以为用户的手机，也可以为其他能够接收警报信号的电子设备等，优选地，当判断初始图像与对比图像的相似度小于预设阙值，则向预设终端发送警报信息，进一步包括：判断三组相似度比对的结果之中任一一组相似度小于预设相似度阙值，则向预设终 端发送警报信息，以便提醒用户车辆内具有活体，主驾驶初始图像、副驾初始图像以及全景初始图像与其相对应的对比图像进行相似度比对，若三组比对结果中任一一组相似度小于预设相似度阙值，则说明车内存在活体，则向预设终端发送警报信息，以便提醒用户车辆内具有活体。
本申请实施例中优选地，预设终端提醒用户车辆内具有活体，还包括：预设终端通过预设提醒方式提醒用户，预设提醒方式包括以下之一或多个的组合：文字提醒、图片提醒、震动提醒、灯光闪烁提醒、声音提醒。在判断出车内具有活体后，发送警报信息给预设终端，发送形式包括但不限于：通过网络发送信息给预设终端，预设终端通过预装的应用程序接收警报信息；通过发送短信，电话等形式至预设终端。终端接收到警报信号后，通过文字，图片，震动，灯光闪烁，声音等方式提醒用户车内具有活体。
通过预设启动策略可以判断车内是否有人，在用户没有离开车辆附件的时候不需要开启车内环境监控，所以，在用户离开车辆之后，还需要进一步判断用户是否离开了车辆附近，当车内没有人且用户离开了车辆的附近，才需要开启车内环境监控。人们从驾驶室出来以后，在离开车辆附件时往往习惯于从车前方经过，如果判断预设时间段内有人从车前方经过，就可以判断用户从车附近离开了，对于步骤S102来说，优选地，判断车门满足预设启动策略，还包括：获取预设时间段内的车辆前方视频或图像，其中获取预设时间段内的车辆前方图像，包括：获取从车门锁定时开始至预设时间段内的车辆前方图像，车辆前方图像为多张；判断视频或车辆前方图像中是否有人移动，若判断结果为是，则启动车内环境监控模式；其中，判断车辆前方图像中是否有人移动，包括：将多张车辆前方图像按照时间顺序从前到后依次进行相似度比对，当相似度小于预设相似度阙值时，判断图像中有人移动，通过获取预设时间段内的车辆前方的视频，对视频进行处理分析，可以判断出是否有人在车前方移动，或者获取预设时间段内车辆前方的图像，在预设时间段内获取车辆前方的多张图像，判断车辆前方图像中是否有人在移动，通过车辆前方的图像进行判断车辆前方是否有人移动的过程为：按照时间顺序，从前往后将获取的图像依次进行对比，比如，一段时间内拍了三张图片，最先拍的为图像1，之后是图像 2，最后拍的是图像3，按照时间顺序，从前往后依次进行相似度比对，图像2与图像1对比，图像3与图像2对比，当这两组比对结果中有一组相似度比对结果小于预设相似度阙值，则可以判断车辆前方有人移动。通过车前方视频或图像判断出有人在车前方进行移动的情况下，可以说明用户已经离开了车辆附近，则开启车内环境监控模块。
为了避免外界环境对车内环境监控的影响，对于步骤S103来说，优选地，将初始图像与预存的对比图像进行相似度比对，进一步包括：划定初始图像和对比图像的比对区域，并在比对区域内进行相似度对比。优选地，将初始图像与对比图像进行相似度比对，之前还包括：将初始图像和对比图像进行预处理，以便排除光线干扰。例如，由于车外的运动物体有可能透过车窗而被摄像头拍摄到，如果对车窗区域内进行初始图像和对比图像进行相似比对则有可能会造成误判，对此，用户可将车窗等有可能造成误判的背景区域排除在比对区域之外，从而可避免车外运动目标造成的比对影响，划定初始图像和对比图像的比对区域，并在比对区域内进行相似度对比。同时，由于车内的光照、震动等参数在不同的时间或场景中各不相同，因此，为了避免这些参数对图像获取造成影响，在初始图像与对比图像进行相似度比对之前，需要对初始图像与对比图像进行预处理，包括图像去噪、图像增强、图像去畸变、图像几何变换等，在此不作限定，以消除图像中无关的信息，恢复有用的真实信息，增强有关信息的对比性，从而为比对分析提供可靠的基础图像。
实施例2：
在实施例1的基础上，本申请还提供另一个实施例，在实施例1的基础上增加了车内声音分贝检测，若车内具有活体的情况下，车内的声音的分贝值必然大于车内没有活体的声音分贝值，由此可以进一步判断车内是否具有活体。
在实施例1步骤S104的基础上，优选地，当判断初始图像与对比图像的相似度小于预设阙值，进一步包括：启动声音分贝检测功能，检测车辆内预设时长内的声音分贝值并记录；判断声音分贝值是否超过预设分贝阙值；当判断声音分贝值超过预设分贝阙值，则向预设终端发送警报信息。
在判断初始图像与对比图像相似度小于预设阙值时，已经能够基本判断车内没有活体，但是为了防止摄像头的拍摄死角，还需要进一步通过声音来判断一下，启动声音分贝检测功能，检测预设时长内车内的声音分贝值并记录，判断声音分贝值是否大于预设分贝阙值，当检测到的声音分贝值大于预设分贝阙值时，则可判断车内具有活体，则向预设终端发送警报信息。
