Azure Kinect 传感器 SDK使用

- 不同深度模式有什么区别?
NFOV为正六边形镜头,适用于窄视角;WFOV为圆形镜头,适用于宽视角。UNBINNED是将采集图像的每个像素作为一个用于分析的数据,2X2BINNED是将采集得到的图像每2x2的方格做平均后作为一个用于分析的数据,相当于2X2BINNED模式在x轴和y轴上对UNBINNED模式进行了下采样。
(binned进行了一个池化操作?)




- 单主机多Kinect联合录制
从机
k4arecorder.exe --device 1 --external-sync subordinate --imu OFF -e -8 -r 5 -l 5 output-2.mkv
主机
k4arecorder.exe --device 0 --external-sync master --imu OFF -e -8 -r 5 -l 5 output-1.mkv
注意:
从机主机的device不能错误,可以通过k4arecorder.exe --list
查看sync-out接口对应的主机序列号,以及sync-in接口对应的从机序列号
imu默认不打开
-e 曝光 范围1-11 默认自动
-r rate 可以选择30 15 5 默认最大fps
-l limited 时间(s) 记录时间
输出文件尽量选择绝对路径(我的自动路径不存在)
我的命令一般是
k4arecorder.exe --device 1 --external-sync subordinate --imu OFF d:\output-2.mkv
多主机录制
从设备
k4arecorder.exe --external-sync sub -r 15 --imu OFF sub1.mkv
主设备
k4arecorder.exe --external-sync master -r 15 --imu OFF master.mkv
k4arecorder [options] output.mkv
Options:
-h, --help Prints this help
--list List the currently connected K4A devices
--device Specify the device index to use (default: 0)
-l, --record-length Limit the recording to N seconds (default: infinite)
-c, --color-mode Set the color sensor mode (default: 1080p), Available options:
3072p, 2160p, 1536p, 1440p, 1080p, 720p, 720p_NV12, 720p_YUY2, OFF
-d, --depth-mode Set the depth sensor mode (default: NFOV_UNBINNED), Available options:
NFOV_2X2BINNED, NFOV_UNBINNED, WFOV_2X2BINNED, WFOV_UNBINNED, PASSIVE_IR, OFF
--depth-delay Set the time offset between color and depth frames in microseconds (default: 0)
A negative value means depth frames will arrive before color frames.
The delay must be less than 1 frame period.
-r, --rate Set the camera frame rate in Frames per Second
Default is the maximum rate supported by the camera modes.
Available options: 30, 15, 5
--imu Set the IMU recording mode (ON, OFF, default: ON)
--external-sync Set the external sync mode (Master, Subordinate, Standalone default: Standalone)
--sync-delay Set the external sync delay off the master camera in microseconds (default: 0)
This setting is only valid if the camera is in Subordinate mode.
-e, --exposure-control Set manual exposure value (-11 to 1) for the RGB camera (default: auto exposure)
