python中参数设置和滤波相关¶

这里介绍在python中相关参数的设置读取和滤波功能的开启关闭。

python下参数设置和读取¶

单个参数设置，如设置帧格式:

wparams_fmt = {dmcam.PARAM_FRAME_FORMAT: dmcam.param_val_u()}
wparams_fmt[dmcam.PARAM_FRAME_FORMAT].frame_format.format = 2
if not dmcam.param_batch_set(dev, wparams_fmt):
        log.error(" frame format failed")

单个参数读取，如读取积分时间:

param_val = dmcam.param_batch_get(dev, [dmcam.PARAM_INTG_TIME])
param_intg_us = param_val.intg.intg_us

python下滤波功能开启和关闭¶

像素校准，用于深度数据校正:

drnu_param = dmcam.filter_args_u()
drnu_param.case_idx = 0  #  12MHz calibaration
dmcam.filter_enable(dev, dmcam.DMCAM_FILTER_ID_PIXEL_CALIB, drnu_param, 0)      #使能像素校准

dmcam.filter_disable(dev, dmcam.DMCAM_FILTER_ID_PIXEL_CALIB)    #关闭像素校准

深度滤波，用于深度数据滤波:

filter_param = dmcam.filter_args_u()
filter_param.median_ksize = 3           # 深度滤波通常设置值
dmcam.filter_enable(dev, dmcam.DMCAM_FILTER_ID_MEDIAN, filter_param, sys.getsizeof(filter_param))       #使能深度滤波

dmcam.filter_disable(dev, dmcam.DMCAM_FILTER_ID_MEDIAN) #关闭深度滤波

幅值滤波，用于过滤质量差的点:

amp_min_val = dmcam.filter_args_u()
amp_min_val.min_amp = 30        #设置最小幅值滤波的阈值
dmcam.filter_enable(dev, dmcam.DMCAM_FILTER_ID_AMP, amp_min_val, sys.getsizeof(amp_min_val))    #使能幅值滤波

dmcam.filter_enable(dev, dmcam.DMCAM_FILTER_ID_AMP)             #关闭幅值滤波

自动积分时间，开启模组根据被测物自动调整曝光时间:

intg_auto_arg = dmcam.filter_args_u()
intg_auto_arg.sat_ration = 5    #自动曝光设置的值
dmcam.filter_enable(dev, dmcam.DMCAM_FILTER_ID_AUTO_INTG, intg_auto_arg, sys.getsizeof(intg_auto_arg))  #开启自动曝光

dmcam.filter_disable(dev,DMCAM_FILTER_ID_AUTO_INTG)             #关闭自动曝光

运动模式0，帧格式设置2:

dmfilter = dmcam.filter_args_u()

wparams_fmt = {dmcam.PARAM_FRAME_FORMAT: dmcam.param_val_u()}
wparams_fmt[dmcam.PARAM_FRAME_FORMAT].frame_format.format = 2   #要设置帧格式为2
dmcam.param_batch_set(dev, wparams_fmt)         #进行帧格式参数设置

dmfilter.sport_mode = 0         #设置运动模式为0
dmcam.filter_enable(dev, dmcam.DMCAM_FILTER_ID_SPORT_MODE, dmfilter, 0)         #开启运动模式0

dmcam.filter_disable(dev, dmcam.DMCAM_FILTER_ID_SPORT_MODE)             #关闭运动模式0

运动模式1，帧格式设置4:

dmfilter = dmcam.filter_args_u()

wparams_fmt = {dmcam.PARAM_FRAME_FORMAT: dmcam.param_val_u()}
wparams_fmt[dmcam.PARAM_FRAME_FORMAT].frame_format.format = 4 #要设置的帧格式为4
dmcam.param_batch_set(dev, wparams_fmt)  #进行帧格式设置

dmfilter.sport_mode = 1         #设置运动模式为1
dmcam.filter_enable(dev, dmcam.DMCAM_FILTER_ID_SPORT_MODE, dmfilter, 1)         #开启运动模式1

#关闭运动模式1时，帧格式要先恢复到2
wparams_fmt = {dmcam.PARAM_FRAME_FORMAT: dmcam.param_val_u()}
wparams_fmt[dmcam.PARAM_FRAME_FORMAT].frame_format.format = 2 #恢复帧格式为2
dmcam.param_batch_set(dev, wparams_fmt)  #进行帧格式设置

dmcam.filter_disable(dev, dmcam.DMCAM_FILTER_ID_SPORT_MODE)             #关闭运动模式1
