大家好,又见面了,我是你们的朋友全栈君。
驱动修改点
A:sensor_xxxx_mipi_raw.c
1.获取PD信息函数
static const cmr_u16 xxxx_pd_is_right[] = PD点位置信息,遮住右半边表示右点,用1表示,遮住左半边表示左点,用0表示;具体需要看sensor
static const cmr_u16 xxxx_pd_row[] =PD位置行坐标
static const cmr_u16 xxxx_pd_col[] = PD位置列坐标
static const struct pd_pos_info _xxxx_pd_pos_l[] = 左PD点坐标
static const struct pd_pos_info _xxxx_pd_pos_r[] = 右PD点坐标
static const cmr_u32 xxxx_pd_sns_mode[] =未配置PDAF填写0,配置PDAF填写1
static cmr_int xxxx_drv_get_pdaf_info(cmr_handle handle, cmr_u32 *param) {
cmr_int rtn = SENSOR_SUCCESS;
struct sensor_pdaf_info *pdaf_info = NULL;
cmr_u16 i = 0;
cmr_u16 pd_pos_row_size = 0;
cmr_u16 pd_pos_col_size = 0;
cmr_u16 pd_pos_is_right_size = 0;
SENSOR_IC_CHECK_PTR(param);
pdaf_info = (struct sensor_pdaf_info *)param;
pd_pos_is_right_size = NUMBER_OF_ARRAY(xxxx_pd_is_right);
pd_pos_row_size = NUMBER_OF_ARRAY(xxxx_pd_row);
pd_pos_col_size = NUMBER_OF_ARRAY(xxxx_pd_col);
if ((pd_pos_row_size != pd_pos_col_size) ||
(pd_pos_row_size != pd_pos_is_right_size) ||
(pd_pos_is_right_size != pd_pos_col_size)) {
SENSOR_LOGE("pd_pos_row size and pd_pos_is_right size are not match");
return -1;
}
pdaf_info->pd_offset_x =PD起始点坐标
pdaf_info->pd_offset_y =
pdaf_info->pd_end_x =PD结束点坐标
pdaf_info->pd_end_y =
pdaf_info->pd_block_w = width of basic pd pattern:0:8 ;1:16;2:32;3:64;max :3
pdaf_info->pd_block_h =
pdaf_info->pd_block_num_x = horizontal number of basic pd pattern
pdaf_info->pd_block_num_y =
//
计算公式:
pd_end_x = pd_offset_x + pd_block_num_x * pd_block_w * pd_density_x
以上都可以在sensor spec中找到或者找sensor FAE要
/
pdaf_info->pd_is_right = (cmr_u16 *)xxxx_pd_is_right;
pdaf_info->pd_pos_row = (cmr_u16 *)xxxx_pd_row;
pdaf_info->pd_pos_col = (cmr_u16 *)xxxx_pd_col;
cmr_u16 pd_pos_r_size = NUMBER_OF_ARRAY(_xxxx_pd_pos_r);
cmr_u16 pd_pos_l_size = NUMBER_OF_ARRAY(_xxxx_pd_pos_l);
if (pd_pos_r_size != pd_pos_l_size) {
SENSOR_LOGE("pd_pos_r size not match pd_pos_l");
return -1;
}
pdaf_info->pd_pitch_x = 32;
pdaf_info->pd_pitch_y = 32;
pdaf_info->pd_density_x = 16;//distance between PD pairs
pdaf_info->pd_density_y = 8;
pdaf_info->pd_pos_size = pd_pos_r_size;
pdaf_info->pd_pos_r = (struct pd_pos_info *)_xxxx_pd_pos_r;
pdaf_info->pd_pos_l = (struct pd_pos_info *)_xxxx_pd_pos_l;
pdaf_info->vendor_type = SENSOR_VENDOR_xxxx;
pdaf_info->sns_orientation = 0; /*0 Normal, 1 mirror+flip*/
pdaf_info->vch2_info.bypass = 0;
pdaf_info->vch2_info.vch2_vc = 0;//VC( virtual channel mode)及DT(different data type mode)开关
pdaf_info->vch2_info.vch2_data_type = 0; //sensor spec查找
pdaf_info->vch2_info.vch2_mode = 0x03; //0x01 type2 ; 0x02 virtual_channel;0x03 type3
//type1: 只有对焦计算由平台来做,其他由sensor完成。(比如说BPC、PD检测等)
//type2: PD检测、对焦计算由平台来做。
//type3: 所有的工作都由平台来做,ISP必须支持BPC校正、PD解析、对焦计算等功能。
pdaf_info->sns_mode = xxxx_pd_sns_mode;
return rtn;
}
以上需要填写的值可以直接找sensor FAE索要ini文件即可,也可以自己计算和查找
2.上传PD数据
case SENSOR_VAL_TYPE_GET_PDAF_INFO:
rtn = xxxx_drv_get_pdaf_info(handle, param_ptr->pval);
B:sensor_xxxx_mipi_raw.h
.pdaf_supported = SENSOR_PDAF_TYPEx_ENABLE
上述 pdaf_info->vendor_type = SENSOR_VENDOR_xxxx; 流程 SENSOR_VENDOR_xxxx 添加
1.cmr_sensor_info.h
SENSOR_VENDOR_xxxx
2.pdaf_sprd_adpt.h
#define SENSOR_ID_num
3.pdaf_sprd_adpt.c
else if (SENSOR_VENDOR_xxxx == in_p->pd_info->vendor_type) {
cxt->pd_gobal_setting.dSensorMode = SENSOR_ID_num;
} else {
cxt->pd_gobal_setting.dSensorMode = SENSOR_ID_1024;
}
确认PDAF导通debug
ispalg_bypass_init: pdaf sw bypass: 0
pdaf_ctrl: 519, pdaf_ctrl_ioctrl: sensor don't support PDAF
2.确认PDAF type是否正确
sprd_afv1_init: is_multi_mode 0, cameraid 0, sensor_role 0, pdaf_type 0
3.确认OTP数据
PDAF OTP 无数据,异常
D PDAlgo : Calibration[1]: OTP Buffer is NULL!
PDAF OTP 有数据
D PDAlgo: SPRD OTP Data Init Start!
D PDAlgo: SPRD OTP Data Init Done!
PDAlgo: PDResult: One Center Area[0] PD[-10.563253] Conf[107277] DCC[22] MAXSAD[762362] MINSAD[655085]
有对应的PD值和 conf值 ,相位差范围:[-16,+16] , 出现上面两个值一直是0 , 则需要找算法确认原因。
5.展锐PDAF触发是通过效果调参来触发,底层驱动只负责导通和确认正常即可,如OTP的正确性
OTP dump之后通ISP工具打开确认spc和dcc数据 adb shell setprop debug.camera.save.otp.raw.data 1 data/vendor/cameraserver路径下 其实直接看Log就可以看出来,如第四步中DCC中log的数值就可以看出来,如果PD点填反了,DCC的值就是负值
1.af_sprd_adpt_v1: 1521, af_init: PDAF Tuning NULL! ——》未添加PDAF模块
调试的时候adb设置打开log,如果设置之后搜不到相关的log,那就是使能开关suppport.pd.data_support没有打开
//
adb shell setprop debug.isp.aft.mlog save //打开aft相关log
adb shell getprop debug.isp.aft.mlog //检查是否成功打开aft log
//
2.添加调整效果参数 按照文档将使能开关suppport.pd.data_support打开,之后调整下列参数 修改其中一组之后,其他组发生改变是正常的,参数设置需要满足以下条件:
pd_value_abs_trig:相位差均值*1000大于此参数设置值,才满足触发,[0][1][2]分别表示室内、室外、低亮。
越小越容易触发PD,但容易失焦,最好不小于1000。
pd_value_stable:相位差方差*1000小于此参数设置值,才满足触发。判断相位差是否稳定,越小越容易触发。
(这个值对PD触发率的影响不太大)
pd_stable_cnt:当满足其余触发条件下,有此参数设置值相应帧数都满足,才满足触发。
pd_bv_thr:控制触发的亮度条件,当BV值大于此参数设置值,才满足触发。
pd_conf_th_table:[0]-[32]表示相位差-16-16,相位差对应的信心度大于此参数设置值,才满足触发。
PDAF触发是需要下列参数都满足才会触发:
pd_data_support:设置1才能打开PDAF功能。
pd_value_abs_trig:相位差均值*1000大于此参数设置值,才满足触发。
pd_value_stable: 相位差方差*1000小于此参数设置值,才满足触发。
pd_conf_th_table:相位差对应的信心度大于此参数设置值,才满足触发。
pd_bv_thr:控制触发的亮度条件, 当BV值大于此参数设置值, 才满足触发。
pd_stable_cnt:连续N帧满足其余触发参数设定条件,才可触发。例如,pd_stable_cnt=6,
那么需要连续6帧都满足其余触发参数条件设定,才可以触发,否则不触发。
