附图说明
此处所说明的附图用来提供对本发明的进一步理解，构成本发明的一部分，本发明的示意性实施例及其说明用于解释本发明，并不构成对本发明的不当限定。在附图中：
图1为本发明实施例提供的光源参数测量方法流程示意图；

具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合本发明具体实施例及相应的附图对本发明技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
如图1所示，本发明实施例提供一种光源参数测量方法，所述方法包括如 下步骤：
S102：采集颜色传感器针对待测光源的信号值。
其中，上述颜色传感器包括至少6个响应通道，这多个(即上述至少6个)响应通道对应的波长在可见光的波长范围(380～780nm)内均匀分布。该处提到的均匀分布，可以是非严格意义上的均匀，例如，在一个具体的例子中，颜色传感器包括6个响应通道，这6个响应通道对应的波长分别为450nm，500nm，550nm，570nm，600nm，650nm。
在一实施方式中，上述颜色传感器分别在第一波长取值范围、第二波长取值范围和第三波长取值范围内，均至少对应有1个响应通道；其中，所述第一波长取值范围为435～455nm，所述第二波长取值范围为545～565nm，所述第三波长取值范围为590～610nm，单位均是nm。通过上述设置，能够比较准确地测量出待测光源的光源参数。
在一个具体的例子中，上述颜色传感器在445nm，555nm，600nm波长位置或傍边波长位置(峰值波长位置差≤10nm，进一步波长位置差≤5nm)均至少有一个响应通道，也即，在445nm波长位置或傍边波长位置至少有一个响应通道；在555nm波长位置或傍边波长位置至少有一个响应通道；在600nm波长位置或傍边波长位置至少有一个响应通道。
在一实施方式中，上述至少6个响应通道均为窄带响应通道，上述至少6个响应通道的半宽度均小于或等于预设值。在一个具体的例子中，上述颜色传感器的每一个响应通道对应的响应光谱的半宽度≤50.0nm，也即本发明生采用的是窄带响应的颜色传感器，能够比较准确地测量出待测光源的光源参数。
可以理解，在一定的数值范围内，颜色传感器包括的响应通道的数量越多，最终测量得到的光源参数的精度也越高。
但考虑到颜色传感器的响应通道的数量增多后，光源参数计算的复杂度也 相应增加，因此，在一个优选的实施例中，上述颜色传感器的响应通道的数量是6～18，该6～18个响应通道分别对应的波长在可见光的波长范围内均匀分布。
通过上述颜色传感器的响应通道的数量设置，不仅能够提高颜色测量得到的光源参数的精度；同时将光源参数计算的复杂度控制在合理的范围内，节约计算处理过程中所需要的资源。
S104：对采集到的信号值进行预处理。
其中，上述预处理过程包括归一化处理和正态化处理等。
在一个具体的例子中，上述颜色传感器采集到的信号值是{T 1，T 2，T 3，…，T i}，其中，i表示上述颜色传感器的响应通道的序号的最大值。
步骤S104中对采集到的信号值进行归一化处理时，可以采用N阶范数的归一化处理方式，即，首先采用如下公式得到缩放因子F，
Figure PCTCN2019130412-appb-000001
然后，针对采集到的{T 1，T 2，T 3，…，T i}中的每一个信号值，均采用如下公式进行缩放，从而将和光通量相关的信号值，转化成和光通量无关的数值。
T i′＝T i/F
最后，采用如下公式，对归一化处理后的i个信号值T i′进行正态化处理，
T i″＝(T′-μ)/σ
上述公式中，μ是平均数，σ是标准差。其中，μ和σ可以是预先根据大量的相关样本集得到。
在一个具体的例子中，可预先得到上述颜色传感器针对多个基准光源的信号值；然后，针对每一个基准光源的信号值，采用上述归一化处理方式对其进行归一化处理；这样，根据上述多个基准光源归一化处理后的信号值，即可计算得到上述平均值μ和标准差σ。
本发明实施例中，通过对采集到的信号值进行归一化处理和正态化处理等，从而便于后续步骤中的模型特征构建以及确定待测光源的光源类型等。
S106：根据预处理后的信号值构建模型特征，并根据构建出的模型特征确定待测光源的光源类型。
其中，上述构建出的模型特征和预设的显色指数预测模型相匹配。
在一实施方式中，本发明实施例执行之前，可以根据上述颜色传感器针对多个基准光源的信号值，以及上述多个基准光源的显色指数进行模型训练，生成上述显色指数预测模型，该显色指数预测模型可以用来预测待测光源的显色指数。
其中，在模型训练时，上述多个基准光源的显色指数可以是通过光谱仪得到，光谱仪测量显色指数虽然过程复杂，但是能够保证显色指数的测量精度。在显色指数预测模型的建模时，通过光谱仪得到准确地显色指数，进一步提高模型训练的预测的准确性。在一实施方式中，上述显色指数预测模型可采用神经网络模型、回归树模型、广义线性回归模型等，或是以上模型的组合和堆叠。
这样，根据显色指数预测模型所需要的模型特征，对步骤S104预处理后的信号值进行特征构建，构建出显色指数预测模型所匹配的模型特征。构建出模型特征可以包括线性特征、非线性特征以及基于上述两种特征的组合特征，上述构建出的模型特征和预设的显色指数预测模型所需要的模型特征符合，也即该步骤构建出的模型特征和上述预设的显色指数预测模型相匹配。
在一个具体的实施方式中，可以采用如下特征构建公式，对步骤S104预处理后的多个信号值执行特征构建的操作：
{P}＝h{f(T i″)+g(T i″)}
经过上述公式，即可将原有的i个信号值，转换为数量为L(L>＝i)的特征集{P}。上述公式中，f(x)、g(x)和h(x)分别表示线性特征构建函数、非线性特征构建函数和组合特征构建函数。
在一实施方式中，在步骤S108之前，还可以根据构建出的模型特征确定所述待测光源的光源类型Y，其中，光源类型Y包括但不限于发光二极管(LED)、紧凑型荧光灯或日光灯(CFL)、高压气体放电灯(HID)、自然光等。
该实施例具体可以采用光源类型分类模型确定待测光源的光源类型Y，其中，光源类型分类模型可以是神经网络模型、支持向量机模型(SVM)、决策树模型、随机森林模型等，或是以上模型的组合和堆叠。光源类型分类模型的建模过程和上述显色指数预测模型的建模过程类似，在此不再赘述。
该实施例中，显色指数预测模型针对不同类型的光源设置有不同的权重系数，进而能够提高显色指数预测模型的预测精度。
S108：将模型特征和光源类型输入显色指数预测模型，得到待测光源的显色指数。
本发明实施例提供的光源参数测量方法，通过采集颜色传感器针对待测光源的信号值，对采集到的信号值进行预处理后构建模型特征，根据模型特征确定待测光源的光源类型，将构建出模型特征和确定出的光源类型输入显色指数预测模型即可得到待测光源的显色指数，相对于现有技术中光谱仪测量显色指数的方法，因仅仅需要颜色传感器以及构建出的显色指数预测模型，显色指数的测量过程简单。
以上述图1所示的实施例为基础，在一实施方式中，在步骤S102中采集颜色传感器针对待测光源的信号值之后，还可以包括如下步骤：根据采集到的信号值和预设的转换系数，得到待测光源的三刺激值；根据得到的上述三刺激值，得到所述待测光源的色坐标、色温和照度中的至少一种。
具体地，若采集到的信号值是{T 1，T 2，T 3，…，T i}，其中，i表示响应通道的序号的最大值，则可以基于如下公式得到待测光源的三刺激值：
Figure PCTCN2019130412-appb-000002
在该公式中，X，Y，Z分别表示待测光源的三刺激值；[K sensor]是转换系数，具体可以是一矩阵系数。
具体地，在上述得到待测光源的三刺激值之后，可以分别采用如下公式得到待测光源的色坐标。
x＝X/X+Y+Z
y＝Y/X+Y+Z
在该处的两个公式中，x，y分别表示色坐标(x,y)的横坐标值和纵坐标值；X，Y，Z分别表示待测光源的三刺激值。
在得到待测光源的色坐标之后，还可以采用如下公式得到待测光源的色温CCT。
CCT＝437n 3+3601n 2+6831n+5517
在该公式中，变量n可以基于待测光源色坐标的横坐标值和纵坐标值计算得到：
n＝x-0.3320/0.1858-y
具体地，在上述得到待测光源的三刺激值之后，还可以采用如下公式得到待测光源的照度illuminance。
illuminance＝K 照度×Y
在该公式中，K 照度是常量，Y是待测光源的三刺激值中的绿原色刺激量。K 照度可以是用标准光谱照度计，和本发明实施例提供的光源参数测量装置(后续实施例介绍)在基准光源相同位置上测试比对得到：
Figure PCTCN2019130412-appb-000003
在该公式中，illuminance std是标准光谱照度计针对上述基准光源的照度值，Y std是 本发明实施例提供的光源参数测量装置针对上述基准光源的照度值。
在上述实施例中计算待测光源的三刺激值时需要用到转换系数[K sensor]，在一实施方式中，在上述多个实施例之前，还可以包括如下步骤：
根据上述颜色传感器针对多个基准光源的信号值，以及光谱仪针对上述多个基准光源的三刺激值，计算得到转换系数[K sensor]。
在计算转换系数[K sensor]时，具体可以采用如下步骤：
a)预先选取多个不同光谱的基准光源(或称作基准灯)，包括但不限于不同色温的LED灯、不同色温的荧光灯、不同色温的白炽灯以及不同色温的陶瓷金卤灯CDM等。
优选地，基准灯的数量≥n*颜色传感器的响应通道数，n≥1，n不局限于整数；上述基准灯的光通量范围可以是100～4000lm，或照度范围可以是100～4000lx。
优选地，在不同的光通量范围或照度范围内，至少包括有一个基准灯。或者说，上述多个基准灯的光通量在上述光通量范围内均匀分布，或者，上述多个基准灯的照度范围在上述照度范围内均匀分布。
b)把上述多个基准灯(每次放置一个基准灯，多个基准灯依次测量)和包含颜色传感器的器件同时放置在积分球内，基准灯放置在积分球中心，本发明实施例提供的光源参数测量装置(后续实施例介绍)放置在积分球内切面，受光方向正对积分球中心。积分球是一个内壁涂有白色漫反射材料的空腔球体，又称光度球，光通球等，积分球的光经过内壁涂层多次反射，在内壁上形成均匀照度。
c)基准灯点亮稳定后，同时用光谱仪得到基准灯的基准光源的三刺激值{X n，Y n，Z n}；用本发明上述各个实施例提到的颜色传感器(包含在光源参数测量装置内)得到信号值{T n1，T n2，T n3，...，T ni}。其中，序号n表示第n个基准灯，i表示颜色传感器的响应通道数的序号。
d)通过如下公式计算转换系数[K sensor]
[K sensor]＝(M′M) -1(M′N)
其中，M和N分别参见如下公式：
Figure PCTCN2019130412-appb-000004
Figure PCTCN2019130412-appb-000005
上述各个实施例通过计算得到转换系数[K sensor]，并利用[K sensor]来计算待测光源的色坐标、色温和照度等，由于在计算转换系数时采用了大量的基准灯，同时采用了测量精度较高的光谱仪，提高了得到的转换系数[K sensor]的准确度，从而使基于该转换系数[K sensor]得到的待测光源的色坐标、色温和照度等的精度较高。
与上述各个实施例提到的光源参数测量方法相对应，如图2和图3所示，本发明实施例还提供一种光源参数测量装置，该装置包括颜色传感器302和微控制单元MCU303，如图2所示，所述MCU 303包括信号预处理模块201、特征构建模块202、光源类型分类模块203和显色指数预测模块204，其中，所述颜色传感器302，可以用于输出针对待测光源的信号值，所述颜色传感器包括至少6个响应通道；所述信号预处理模块201，可以用于对所述颜色传感器302输出的信号值进行预处理，所述预处理包括归一化处理和正态化处理；所述特征构建模块202，可以用于根据预处理后的信号值构建模型特征；光源类型分类模块203，可以用于根据所述模型特征确定所述待测光源的光源类型；所述显色指数预测模块204，可以用于将所述模型特征和确定出的光源类型输入所述显色指数预测模型，得到所述待测光源的显色指数。
