Abstract
Rotation data and translational data are received. A calibration operator is determined based on the rotation data and translational data, where the calibration operator is useable to relatively calibrate the rotation data and the translation of data.
Claims20
A method comprising:
- placing a plurality of seismic sensors proximate to the earth surface, each of the seismic sensors having a first translational motion sensor, a first rotation sensor and a second rotation sensor;
- receiving ground-roll rotation data based on measurement by the rotation sensors;
- receiving translational data from the translational seismic sensors;
- and
- determining a calibration operator based on the ground-roll rotation data and translational data, wherein the calibration operator is useable to relatively calibrate the ground-roll rotation data and the translational data.
2 more elements
A system comprising:
- at least one storage medium to store ground-roll rotation data and translational data acquired based on measurement from a plurality of seismic sensors, each seismic sensor having a translational movement sensor, a first rotation sensors and a second rotation sensor;
- and
- at least one processor to:
- determine a calibration operator based on the ground-roll rotation data and translational data, wherein the calibration operator is useable to relatively calibrate the ground-roll rotation data and the translational data.
1 more element
An article comprising at least one non-transitory machine-readable storage medium storing instructions that upon execution cause a system to:
- receive ground-roll rotation data based on measurement by a plurality of seismic sensors, each seismic sensor having a translational sensor, a first rotation sensor and a second rotation sensor;
- receive translational data from the plurality of seismic sensors;
- and
- determine a calibration operator based on the ground-roll rotation data and translational data, wherein the calibration operator is useable to relatively calibrate the ground-roll rotation data and the translational data.
