STRUCTURED-LIGHT BASED MULTIPATH CANCELLATION IN TOF IMAGING

摘要

Representative implementations of devices and techniques provide multipath interference cancelling for imaging devices and systems. In various implementations, structured light is used to diminish, if not cancel interference. For example, the light may be structured with respect to amplitude or phase, based on an emission angle of the light.

主权项

1. An apparatus, comprising:
an imaging sensor arranged to capture light radiation reflected off one or more objects in an area during one or more frame events, the reflected light radiation being subject to multipath interference; and a processing component arranged to control a structure of the light radiation when emitted from a light source, according to emission angles of light rays of the light radiation, the processing component arranged to determine corrected depth values from the captured reflected light radiation using the emission-angle based structure of the light radiation and to calculate a distance from the one or more objects to the imaging sensor, based on the corrected depth values.
