Abstract
A method for depth mapping includes projecting a pattern of optical radiation into a volume of interest containing an object while varying an aspect of the pattern over the volume of interest. The optical radiation reflected from the object responsively to the pattern is sensed, and a depth map of the object is generated based on the sensed optical radiation.
Claims12
A method for depth mapping, comprising:
- projecting a pattern of optical radiation into a volume of interest containing an object while modulating the pattern as a function of angle over the volume of interest;
- sensing a time of flight of the optical radiation reflected from the object responsively to the pattern;
- and
- generating a depth map of the object based on the sensed time of flight.

Apparatus for depth mapping, comprising:
- a radiation source, which is configured to project a pattern of optical radiation into a volume of interest containing an object while modulating the pattern as a function of angle over the volume of interest;
- a sensor, which is configured to output a signal that is indicative, responsively to the pattern, of a time of flight of the optical radiation reflected from the object;
- and
- a processor, which is configured to process the signal in order to generate a depth map of the object.
