Abstract:
To determine depth of an object within a volume, structured light is projected into the volume. The structured light comprises a pattern over which intensity of the light varies. A sensor detects light from the volume and uses variations in intensity of the detected light to correlate the detected light with the pattern. Based on the correlation, depth of objects within the volume is determined.
