Abstract
Various embodiments are provided for calibration of motion player tracking devices in electronic gaming machines (EGMs). A plurality of object sensors positioned adjacently to a display device of the EGM each record a plurality of data frames inclusive of a position of a plurality of fiducial markers relative to the plurality of object sensors. At predetermined intervals, the plurality of object sensors are calibrated in three-dimensional space using the position of the plurality of fiducial markers relative to the plurality of object sensors within the recorded plurality of data frames.
Claims20
An electronic gaming machine (EGM), comprising:
- a display device;
- a plurality of object sensors, wherein a viewable side of a frustum of a first object sensor of the plurality of object sensors is substantially parallel to a face of the display device;
- a plurality of fiducial markers;
- at least one processor;
- and
- at least one memory device storing a plurality of computer instructions that, when executed by the at least one processor, cause the at least one processor to operate with the display device and the plurality of object sensors to:
- record, by the plurality of object sensors, a plurality of data frames inclusive of a relative position of the plurality of fiducial markers adjacently located to the display device;
- and
- calibrate the plurality of object sensors in three-dimensional space using the relative position of the plurality of fiducial markers within the recorded plurality of data frames.
An electronic gaming machine (EGM), comprising:
- a display device configured to display three-dimensional images;
- a plurality of object sensors including at least two cameras positioned adjacent to the display device, wherein a viewable side of a frustum of a first object sensor of the plurality of object sensors is substantially parallel to a face of the display device;
- a plurality of fiducial markers positioned adjacent to the display device;
- at least one processor;
- and
- at least one memory device storing a plurality of computer instructions that, when executed by the at least one processor, cause the at least one processor to operate with the display device and the plurality of object sensors to:
- record, by the plurality of object sensors, a plurality of data frames inclusive of a position of the plurality of fiducial markers relative to the plurality of object sensors;
- wherein a field of view of a first one of the plurality of object sensors and a second one of the plurality of object sensors overlaps;
- and
- calibrate, at predetermined intervals, the plurality of object sensors in three-dimensional space using the position of the plurality of fiducial markers relative to the plurality of object sensors within the recorded plurality of data frames.
A method for calibrating object sensors in an electronic gaming machine (EGM), by a processor, comprising:
- recording, by a plurality of object sensors positioned adjacently to a display device of the EGM, a plurality of data frames inclusive of a position of a plurality of fiducial markers relative to the plurality of object sensors;
- wherein a viewable side of a frustum of a first one of the plurality of object sensors and a second one of the plurality of object sensors are substantially parallel to a face of the display device;
- and
- calibrating, at predetermined intervals, the plurality of object sensors in three-dimensional space using the position of the plurality of fiducial markers relative to the plurality of object sensors within the recorded plurality of data frames.
