Abstract
There is provided in accordance with an aspect of the presently disclosed subject matter, a method operating a depth sensing device. The method includes obtaining a current pulse timing on each of a first and a second depth sensing devices; and allocating an exclusive pulse timeslot to each of said first and second devices, so that during a portion of a frame which corresponds to any one of the pulse timeslots only a respective one of said first device and said second device emits a pulse.
Claims18
A depth sensing system, comprising:
- a first depth sensing device comprising a first projector and a first image sensor, where the first depth sensing device is configured to operate at a first frame rate;
- a second depth sensing device comprising a second projector and a second image sensor, where the second depth sensing device is configured to operate at a second frame rate;
- a processor adapted to configure the first and the second depth sensing devices, such that in a single frame of the first depth sensing device:
- the first projector projects a first projection during a first projection duration;
- the second projector projects a second projection during a second projection duration consecutive to the first projection duration;
- the first image sensor captures an image including a reflection of the first projection during a first exposure period;
- and
- the second image sensor captures an image including a reflection of the second projection during a second exposure period.
