CameraITS测试
ITS测试分为两个部分，PartI和PartII
【PartI】
a、测试Scene0-Scene5详细的资料在官网和测试包里的说明文档已经是一份完整的SOP；
b、各场景需要的样张，可以在CameraITS下各Scene文件下打印
测试SOP：
1、简易测试方法可参考：CmaeraITS\CameraITS.pdf
2、IN-Box测试可参考：https://source.android.com/compatibility/cts/camera-its-box
【PartII】
a、Sensor Funsion是带有陀螺仪项目可能会开启的feature，一般O MR P的项目不会有；
b、测试SOP可参考：https://source.android.com/compatibility/cts/sensor-fusion-quick-start
注意：测试Sensor Fuson的箱子需要linux才能驱动，windows下需要镜像linux才能驱动
【Test方法】
a、 Lunux下需要先保证系统是已经可以正常测试CTS/VTS的；
b、 先进入到CameraITS目录下，然后先source一下，在当前目录下下指令：
$source build/envsetup.sh;
然后指令测试指令$python tools\run_all_tests.py
后面可以加参数$python tools\run_all_tests.py camera=1 senes=1
（表示测试后摄，场景1）
c、windows运行脚本方法，请参考后面详述；
Windows下执行ITS测试脚本方法
- 安装Anaconda-2.1.0-Windows-x86_64.exe 绑定包.(如果是32bit机器,则使用32bit版本)
- 新建系统环境变量PYTHONPATH=D:\CameraITS\pymodules
- 添加系统环境Path变量"C:\Anaconda;C:\Anaconda\Scripts"
- 如果执行脚本时遇到import CV2 error,则参考以下步骤.
- 解压opencv-2.4.11.exe 到村本地目录,将其中的opencv-me\build\python\2.7\x64\cv2.pyd 复制到C:\Anaconda\Lib\site-packages下. (如果是32bit机器,则copy x86下的)
- envsetup.bat放CameraITS文件夹里,执行命令前先将bat在cmd窗口下执行一下。
- 重新执行D:\CameraITS\pyton tools\run_all_tests.py，如果执行时遇到类似下面的报错,请将CameraITS\tools\run_all_tests.py这个文件的subprocess.call(['chmod', 'g+rx', topdir])改为subprocess.call(['chmod', 'g+rx', topdir],shell=True) 具体请参考报错自行debug
单条case测试方法：
1、自行改一个脚本出来，例如叫：run_scene7.py，参考改法后附
2、在tests下新建一个文件夹：scene7
3、如果某项fail，例如：scene1下的test_3a.py前摄测试fail，则把这条case复制到文件夹scene7里；
4、command窗口切到CameraITS目录下，例如：\CameraITS，执行python tools\run_scene7.py camera=1 scenes=1即可
脚本请自行debug修改，附如下样本仅供参考，不提供support：
