Data capture system

A method of data capture, comprising:

• determining whether to perform a calibration check for a set of image sensors;
• when the determination is affirmative, controlling a projector to illuminate a capture volume with virtual fiducial markers;
• controlling each of a set of image sensors, simultaneously with the illumination, to capture respective images of the capture volume;
• and
• determining whether detected positions of the virtual fiducial markers based on the images match expected positions of the virtual fiducial markers;
• and
• validating a calibration of the set of image sensors when the determination is affirmative.

A computing device, comprising:

• a memory storing calibration data defining relative positions of a set of image sensors;
• and
• a processor configured to:
• determine whether to perform a calibration check for a set of image sensors;
• when the determination is affirmative, control a projector to illuminate a capture volume with virtual fiducial markers;
• control each of a set of image sensors, simultaneously with the illumination, to capture respective images of the capture volume;
• and
• determine whether detected positions of the virtual fiducial markers based on the images match expected positions of the virtual fiducial markers;
• and
• validate a calibration of the set of image sensors when the determination is affirmative.
