背景技术
手机中的传感器是手机上通过芯片来感应的元器件，如温度值、亮度值和压力值、磁场值等，是手机中的一个重要模块。而传感器通常都存在精度要求，所以在手机运行过程中需要时常进行校准传感器以保证其满足精度要求。
而不同手机(不同品牌、不同型号的)的结构设计不同，相应地，传感器在不同手机中的放置位置也存在差异，进而带来校准参数的差异。因而具有不同结构设计的手机，即使包含的传感器型号相同，也需要对应设置不同的校准参数。而手机中的传感器与处理器是相互独立的，传感器不能直接通过手机中现有的系统接口(例如安卓手机的系统属性ro.product.name)获取能表征手机结构设计的产品型号等信息，因此现有技术中通常需要对不同手机维护其对应的不同的产品代码，以解决不同手机的校准参数不同的问题。但在手机产品日新月异的今天，手机的产品型号繁多，就会存在产品代码繁多带来的开发及维护成本过高的问题。
因此，发明人认为，有必要针对上述现有技术中存在的问题进行改进。

<实施例>
本发明实施例提供一种传感器的校准参数的配置方法，如图1所示，
应用于电子设备，所述电子设备包含处理器单元以及传感器单元，所述方法通过处理器单元以及传感器单元实施，包括以下步骤：
步骤S1100，处理器单元根据所获取的校准配置信息，设置校准变量，其中，校准变量为可供处理器单元设置以及传感器单元读取的全局变量；
步骤S2100，所述传感器单元根据所读取的所述校准变量，配置校准参数，所述校准参数用于所述传感器单元进行自身校准。
本实施例中的电子设备包含处理器单元以及传感器单元，所述传感器单元通常具有精度要求，因此在电子设备启动时以及运行过程中传感器单元需要进行校准以使得能满足精度要求，但不同的电子设备具有不同的结构设计，对应的传感器单元在电子设备中的位置差异会带来校准参数的差异，因此不同电子设备中的传感器单元进行校准需要不同的校准参数。本实施例由处理器单元根据所获取的校准配置信息，设置校准变量供传感器单元读取后配置校准参数，可以自适应地适配不同电子设备的不同结构设计带来的传感器的校准差异，无需额外的产品代码开发和维护，降低成本。
在一个例子中，所述校准配置信息为传感器单元的校准参数。处理器单元根据获取传感器单元的校准参数，将校准变量设置为传感器单元的校准参 数供传感器单元读取后进行配置，可以直接将传感器单元的校准参数传递至传感器单元，不仅可以自适应地适配不同电子设备的不同结构设计带来的传感器的校准差异，还可以自适应适配其他情况(例如传感器单元的型号不同、结构不同等)带来的传感器的校准差异，进一步降低成本。
但在一些应用场景中，受限于电子设备的存储空间较小或设备性能较差不能支持传递内容较多的校准参数，或是目的仅为自适应地适配不同电子设备的不同结构设计带来的传感器的校准差异，本实施例还提供一种传感器的校准参数的配置方法，所述校准配置信息为所述电子设备的结构类型，所述结构类型用于表征所述电子设备与传感器单元的结构关系，所述方法如图2所示，包括：
步骤S2100，所述处理器单元根据所获取的电子设备的结构类型，将所述校准变量设置为所述结构类型；
步骤S2200，所述传感器单元根据所读取的所述电子设备的结构类型，从预置的包含多个分别与不同电子设备的结构类型对应的备选校准参数的备选列表中，选取与所述电子设备的结构类型对应的备选校准参数，配置为校准参数。
不同的电子设备，对应的结构设计不同，通常采用结构类型来区分不同的结构设计，使得电子设备的结构类型与电子设备的结构设计具有唯一映射的关系，结构设计中包含电子设备的传感器单元在电子设备中的位置信息，因此结构类型可以表征电子设备与传感器单元的结构关系，而电子设备与传感器单元的结构关系又与校准参数对应，因而处理器单元通过配置校准变量供传感器单元读取，将所获取的电子设备的结构类型传递给传感器单元，传感器单元就可以从预置的备选列表中选取与所述电子设备的结构类型对应的备选校准参数配置为校准参数。在本实施例中，可以在电子设备出厂前就将备选列表预置在传感器单元中，还可以在电子设备开机后从远程服务器下载预置在传感器单元中的备选列表，也可以由远程服务器将最新的备选列表下发给电子设备供传感器单元更新。
在一个更具体的例子中，所述电子设备为安卓操作系统的手机，所述校准配置信息为所述手机的产品型号，所述校准变量为所述安卓编译环境中的 环境变量Type，所述方法如图3所示，包括以下步骤：
步骤S3100，所述处理器单元根据所获取的所述手机的产品型号，通过系统编译脚本将所述环境变量Type设置为所述手机的产品型号。
不同产品型号的手机，通常具有不同的结构设计，手机的产品型号与手机的结构设计存在隐含的对应关系，所以手机的产品型号可以作为手机结构类型的一种指示，用于表征电子设备与传感器单元的结构关系。在安卓操作系统中，系统编译脚本可以是shell脚本，而在安卓的编译环境中，环境变量是可以供处理单元通过export命令设置，并供传感器单元读取的全局变量。因此，安卓操作系统的手机中，处理器单元可以通过shell脚本将环境变量Type设置为手机的产品型号。
处理器单元还可以调用系统编译脚本获取所述手机的产品型号，例如通过调用shell脚本获取手机的产品型号。
在步骤S3100之后，进入步骤S3200，所述传感器单元根据通过对应的传感器单元程序脚本读取的环境变量Type，赋值本地的预定义参数，根据所述预定义参数从预定义的所述包含多个分别与不同手机的产品型号对应的备选校准参数的备选列表中，选取与所述手机的产品型号对应的备选校准参数，定义为校准参数。
在本例中，传感器单元程序脚本可以是Python脚本，传感器单元通过Python脚本读取环境变量Type，通过CCFLAGS-Dxxx编译命令将环境变量Type的取值赋值给预定义参数，并且预定义的所述包含多个分别与不同手机的产品型号对应的备选校准参数的备选列表可以预先在传感器单元的驱动程序代码中进行定义，在通过#ifdef XXX命令定义预定义参数，就可以将根据所述预定义参数从预定义的备选列表中选取的所述手机的产品型号对应的备选校准参数定义为校准参数。
在一个例子中，如图1或图2所示的传感器的校准参数的配置方法，还包括，所述处理器单元读取预先设置的所述校准配置信息。
本发明的再一个实施例，还提供一种电子设备4000，如图4所示，包括处理器单元4100和传感器单元4200，用于实施本实施例中如图1或2所 示的方法，在此不再赘述。
电子设备4000，包括处理器单元4100和传感器单元4200：
处理器单元4100，用于根据所获取的校准配置信息，设置校准变量，所述校准变量为可供所述处理器单元设置以及所述传感器单元读取的全局变量；
传感器单元4200，用于根据所读取的所述校准变量，配置校准参数，所述校准参数用于所述传感器单元进行自身校准。
在一个例子中，所述校准配置信息为所述传感器单元4200的校准参数。
在一个例子中，所述校准配置信息为所述电子设备的结构类型，所述结构类型用于表征所述电子设备与传感器单元的结构关系，以及
处理器单元4100，用于根据所获取的电子设备的结构类型，将所述校准变量设置为所述结构类型；
传感器单元4200，用于根据所读取的所述电子设备的结构类型，从预置的包含多个分别与不同电子设备的结构类型对应的备选校准参数的备选列表中，选取与所述电子设备的结构类型对应的备选校准参数，配置为校准参数。
在又一个例子中，处理器单元4100还包括用于读取预先设置的所述校准配置信息的装置。
以上已经结合附图描述了本发明的实施例，根据本实施例，电子设备的处理器根据获取的校准配置信息设置校准变量后，传感器可以通过读取校准变量设置用于其自身校准的较准参数，使得电子设备可以自适应地配置传感器的校准参数，无需对不同结构的电子设备开发和维护不同的产品代码，降低了产品的开发和维护成本。
本领域技术人员应当明白，可以通过各种方式来实现处理器单元和传感器单元。例如，可以通过指令配置处理器单元来实现处理器单元和传感器单元。例如，可以将指令存储在ROM中，并且当启动设备时，将指令从ROM读取到可编程器件中来实现处理器单元和传感器单元。例如，可以将处理器单元和传感器单元固化到专用器件(例如ASIC)中。可以将处理器单元和 传感器单元分成相互独立的单元，或者可以将它们合并在一起实现。处理器单元和传感器单元可以通过上述各种实现方式中的一种来实现，或者可以通过上述各种实现方式中的两种或更多种方式的组合来实现。
