经典好文推荐，通过阅读本文，您将收获以下知识点:

一、创建 LogicalCameraName 相关的metadata
二、导通 LogicalCameraName Middleware 相关配置
三、认 LogicalCameraName 是否创建成功
四、双摄bringup LogicalCameraDevice 导通参考

一、创建 LogicalCameraName 相关的metadata

1.1 LogicalCameraName 文件夹命名规则

主摄_FeatureName

例如：(主摄_bayerwide, 主摄_bayertele, 主摄_bayerbayer, 主摄_bayermono)

预设单摄对应的metadata 已经存在并导通，将主摄(比如：SENSOR_DRVNAME_S5K_MIPI_RAW)的 metadata文件夹 copy 一份；
修改主摄文件夹名为LogicalCameraName;
比如：vendor\mediatek\proprietary\custom\mt**\hal\imgsensor_metadata\xxx_mipi_raw_bayermono

修改创建 LogicalCameraName 文件夹中的metadata文件中 STATIC_METADATA2_BEGIN 后面的主摄的name 修改为LogicalCameraName;
比如：

$grep "S5K" -ri .
./config_static_metadata.lens.S5Kmipiraw.h:STATIC_METADATA2_BEGIN(PLATFORM, LENS, SENSOR_DRVNAME_S5K_MIPI_RAW_bayermono)
./config_static_metadata.module.S5Kmipiraw.h:STATIC_METADATA2_BEGIN(PLATFORM, MODULE, SENSOR_DRVNAME_S5K_MIPI_RAW_bayermono)
./config_static_metadata.module.S5Kmipiraw.h:STATIC_METADATA2_BEGIN(PLATFORM, MOD_OVERWRITE, SENSOR_DRVNAME_S5K_MIPI_RAW_bayermono)
./config_static_metadata_availableKeys.h:STATIC_METADATA2_BEGIN(PLATFORM, AVAILABLE_KEYS, SENSOR_DRVNAME_S5K_MIPI_RAW_bayermono)
./config_static_metadata_custom.h:STATIC_METADATA2_BEGIN(PLATFORM, CUSTOM, SENSOR_DRVNAME_S5K_MIPI_RAW_bayermono)
./config_static_metadata_project.h:STATIC_METADATA2_BEGIN(PLATFORM, PROJECT, SENSOR_DRVNAME_S5K_MIPI_RAW_bayermono)
./config_static_metadata_project.h:STATIC_METADATA2_BEGIN(PLATFORM, PRO_OVERWRITE, SENSOR_DRVNAME_S5K_MIPI_RAW_bayermono)
./config_static_metadata_vendor.h:STATIC_METADATA2_BEGIN(PLATFORM, VENDOR, SENSOR_DRVNAME_S5K_MIPI_RAW_bayermono)

1.2 LogicalCamera Size 修改

LogicalCamera Size相关：config_static_metadata_custom.h

后置人像尺寸：CONFIG_METADATA_BEGIN(android_TUNNING_BACK_PORTRAIT_NORMAL_PICTURE_SIZE)CONFIG_ENTRY_VALUE(4160, MINT32)CONFIG_ENTRY_VALUE(3120, MINT32)CONFIG_METADATA_END()/主副摄照片尺寸CONFIG_METADATA_BEGIN(android_CONTROL_BOKEH_PICTURE_SIZE)CONFIG_ENTRY_VALUE(4160 , MINT32)CONFIG_ENTRY_VALUE(3120 , MINT32)CONFIG_ENTRY_VALUE(1600 , MINT32)CONFIG_ENTRY_VALUE(1200 , MINT32)CONFIG_METADATA_END()

二、导通 LogicalCameraName Middleware 相关配置

Multicamra custom stereo Setting middleware 配置路径：

alps/vendor/mediatek/proprietary/custom/mt**/hal/camera/camera_custom_stereo_setting.h

主摄Name ，副摄Name ，LogicalCameraName(主摄_FeatureName)添加到camera_custom_stereo_setting.h中。
注意：主摄Name ，副摄Name ，LogicalCameraName 需要跟meatdata文件夹中的保持一致。

2.1 配置举例如下：

//主摄Name"{""\"Name\": \"S5K_MIPI_RAW\",""\"Capture Size\": {" //实际双摄图片的最终输出大小。"\"4:3\": [""\"4160x3120\"""],""\"16:9\": [""\"4160x2340\"""]""},""\"IMGOYUV Size\": {" //在有Fov Crop 的情况下，不能配置为Sensor full size,建议比full size 小，或者配置FOV crop的值"\"4:3\": \"4160x3120\",""\"16:9\": \"4160x2340\"""},""\"RRZOYUV Size\": {" //一般配置跟预览size 相等或者稍大，如果IMGOYUV Size的二分之一比预览size 大的话，也可以配置为IMGOYUV Size的二分之一。"\"4:3\": \"2080x1560\",""\"16:9\": \"2080x1170\"""},""\"SensorScenarioZSD\": {" //人像对应的是VSDoF， 对应的Sensor Settings的Sensormode 是Custom1"\"VSDoF\": \"custom1\",""\"3rdParty\": \"custom1\",""\"Zoom\": \"custom1\",""\"MtkDepthmap\": \"custom1\",""\"Multicam\": \"custom1\"""},""\"SensorScenarioRecording\": {""\"VSDoF\": \"Video\",""\"3rdParty\": \"custom1\",""\"MtkDepthmap\": \"custom1\"""},""\"FOV\": {""\"H\": 69.0,""\"V\": 54.4""},""\"Calibration\": {"  "\"Macro Distance\": 80,""\"Infinite Distance\": 5000"  // 标定距离远处 50cm"}//，副摄Name"{""\"Name\": \"SC20_MIPI_RAW\",""\"Capture Size\": {""\"4:3\": ["... ...}//，LogicalCameraName"{""\"Logical Device\":{""\"Name\": \"bayermono\",""\"Features\": [\"VSDoF\"]""},""\"Sensors\": [ \"S5K_MIPI_RAW\", \"SC20_MIPI_RAW\"],""\"Depth Flow\": \"MtkDepthmap\",""\"Module Type\": 2,""\"Baseline\": 1.82,"  //主副摄Sensor 中心距离"\"FOV Crop\": {""\"Disable Crop\": 1" //如果副摄FOV可以 cover 到主摄FOV 就不需要做Crop，配置为Disable Crop，否则配置为 Center Crop"},""\"Depthmap Size\": {""\"4:3\": \"480x360\",""\"16:9\": \"480x272\"""},""\"LDC\": [\"0\"]"}

2.3 部分名词解释

Caputre Size：实际双摄图片的最终输出大小。
IMGOYUV Size：在有Fov Crop 的情况下，不能配置为Sensor full size,建议比full size 小，或者配置FOV crop的值。
RRZOYUV Size：一般配置跟预览size 相等或者稍大，如果IMGOYUV Size的二分之一比预览size 大的话，也可以配置为IMGOYUV Size的二分之一。
SensorScenaricZSD：人像对应的是VSDoF，对应的Sensor Settings的Sensormode 是Custom1 ，详细请看下面举例。
FOV ：市场角，规格说明书中有H/V 或者D两种表达
Calibration：标定距离远处 50cm

Baseline：主副摄Sensor 中心距离，涉及到标定。
FOV Crop：如果副摄FOV可以 cover 到主摄FOV 就不需要做Crop，配置为Disable Crop，否则配置为 Center Crop

2.4 Sensormode 客制化举例

修改S5K_mipi_raw 客制化sensormode 为custom1
比如：在下面文件中添加custom1
\kernel-4.14\drivers\misc\mediatek\imgsensor\src\mt**\camera_project\k6833v1_64\S5K_mipi_raw

.custom1 = {.pclk = 480000000,              //record different mode's pclk.linelength  = 4896,                //record different mode's linelength.framelength = 4084,            //record different mode's framelength.startx = 0,                    //record different mode's startx of grabwindow.starty = 0,                    //record different mode's starty of grabwindow.grabwindow_width  = 4160,      //record different mode's width of grabwindow.grabwindow_height = 3120,      //record different mode's height of grabwindow/*   following for MIPIDataLowPwr2HighSpeedSettleDelayCount by different scenario   */.mipi_data_lp2hs_settle_dc = 85,/*   following for GetDefaultFramerateByScenario()  */.max_framerate = 240,.mipi_pixel_rate = 454400000,},

三、认 LogicalCameraName 是否创建成功

抓开机Log(boot_normal的main log) 确认 LogicalCameraName 是否创建成功

3.1 打开logD命令抓取开启log方式：

adb rootadb shell setenforce 0adb shell setprop persist.vendor.mtk.camera.log_level 3adb shell setprop persist.vendor.debug.camera.log 3adb shell pkill camerahalserveradb shell pkill cameraserver

3.2 Log 关键字：
