Get Baseline和轉換外參 （extrinsics）

Get Disparity Baseline：

Config cfg = new Config();
cfg.EnableStream(Stream.Infrared, 1);
cfg.EnableStream(Stream.Infrared, 2);
var pipe = new Pipeline();
PipelineProfile selection = pipe.Start();
var ir1_stream = selection.GetStream(Stream.Infrared, 0);
var ir2_stream = selection.GetStream(Stream.Infrared, 1);
Extrinsics e = ir1_stream.GetExtrinsicsTo(ir2_stream);
var baseline = e.translation[0];

以下可通過官方自帶例子sensor-control獲得：

Get Video Stream Intrinsics：

var pipe = new Pipeline();
PipelineProfile selection = pipe.Start();
var depth_stream = selection.GetStream(Stream.Depth);
Intrinsics i = depth_stream.GetIntrinsics();

Controlling the Laser：

var pipe = new Pipeline();
PipelineProfile selection = pipe.Start();
var selected_device = selection.Device;
var depth_sensor = selected_device.Sensors[0];

if (depth_sensor.Options.Supports(Option.EmitterEnabled))
{
depth_sensor.Options[Option.EmitterEnabled].Value = 1f; // Enable emitter
depth_sensor.Options[Option.EmitterEnabled].Value = 0f; // Disable emitter
}
if (depth_sensor.Options.Supports(Option.LaserPower))
{
var laserPower = depth_sensor.Options[Option.LaserPower];
laserPower.Value = laserPower.Max; // Set max power
laserPower.Value = 0f; // Disable laser
}

Get Field of View：

var pipe = new Pipeline();
PipelineProfile selection = pipe.Start();
var depth_stream = selection.GetStream(Stream.Depth);
Intrinsics i = depth_stream.GetIntrinsics();
float[] fov = i.FOV; // float[2] - horizontal and vertical field of view in degrees
