Abstract: A method for depth mapping includes providing a depth mapping device comprising a projector, which is configured to project a pattern of optical radiation onto a target area over a first field of view about a projection axis, and a camera, which is configured to capture images of the target area within a second field of view, narrower than the first field of view, about a camera axis, which is offset transversely relative to the projection axis. The projector projects the pattern onto first and second planes at first and second distances from the camera, and the camera captures first and second reference images containing first and second parts of the pattern on the first and second planes, respectively. The first and second reference images are combined to produce an extended reference image including both the first and second parts of the pattern.

Abstract: One disclosed embodiment includes techniques for temperature-dependent reference image correction in structured light projectors that may be used for generating three-dimensional (3D) scene depth maps. The techniques disclosed herein include receiving an indication of a temperature (e.g., an actual current operating temperature or a change in the current operating temperature relative to an established reference temperature) associated with one or more components of a projector and then determining, based on the temperature indication, an amount of adjustment needed to correct a reference pattern image based on an estimated effective focal length change of the projector. Next, a reference pattern image may be appropriately adjusted, e.g., based on the determined amount of effective focal length adjustment caused by the current operating temperature of the projector, to generate a corrected reference image, which may then be used to generate a more accurate 3D scene depth maps at the projector's current operating temperature.

Abstract: A method for projection includes projecting a pattern of structured light with a given average intensity onto a scene. A sequence of images is captured of the scene while projecting the pattern. At least one captured image in the sequence is processed in order to extract a depth map of the scene. A condition is identified in the depth map indicative of a fault in projection of the pattern. Responsively to the identified condition, the average intensity of the projection of the pattern is reduced.

Abstract: A mobile device includes a camera module, including a lens and an image sensor. An inertial sensor in the mobile device outputs a signal indicative of an orientation of the device. A controller corrects one or more focal properties of the camera module responsively to the orientation indicated by the inertial sensor.

Abstract: A proximity sensor includes a light source configured to emit a beam of optical radiation and a detector configured to output an electrical signal in response to the optical radiation that is incident on the detector. A first optical multimode fiber is configured to receive the emitted beam and to direct the emitted beam toward an object. A second optical multimode fiber is configured to receive the optical radiation reflected from the object and to convey the received optical radiation to the detector. A processor is coupled to process the electrical signal so as to compute a distance to the object.
