KinectSensor.ElevationAngle Property

Kinect for Windows 1.5, 1.6, 1.7, 1.8

Gets or sets the elevation angle.

public int ElevationAngle { get; set; }

Property Value

Type: Int32
The sensor elevation angle, in degrees. This value is constrained between MinElevationAngle and MaxElevationAngle.

You can tilt the field of view using the tilt motor in the sensor. The motor allows an additional [+/-27] degrees, which effectively doubles the volume that the field of view could surround.

The tilt is relative to gravity rather than relative to the sensor base. An elevation angle of zero indicates that the Kinect is pointing perpendicular to gravity.

The angle is subject to the physical limitations of the sensor. If the sensor base is resting on a tilted surface, the middle of the sensor's tilt range will not correspond to an elevation angle of zero, and the sensor may not be physically capable of reaching the outer limits of the range allowed by the API.

If the sensor is moved so that the base is at a different angle relative to gravity, or if the sensor is tilted manually, the angle reported by the API will change, even if the elevation angle has not been changed programmatically.

For more information, see Interaction Space.

You should tilt the Kinect as few times as possible, to minimize wear on the sensor and to minimize tilting time. The tilt motor is not designed for constant or repetitive movement, and attempts to use it that way can cause degradation of motor function. To reduce wear, your application should change the elevation angle no more than once per second. In addition, you must allow at least 20 seconds of rest after 15 consecutive changes. If your application exceeds these limits, the tilt motor may experience a lock period during which attempting to set the elevation angle will result in an error code.
