Abstract: Systems and techniques are described herein for enhancing depth representations based on amplitudes of time-of-flight signals. For instance, a computing device can obtain a depth representation of a scene. The depth representation includes depth values based on a time of flight (ToF) signal. The computing device can obtain amplitude values corresponding to the depth values of the depth representation. The amplitude values are based on the ToF signal. The computing device can smooth the depth values based on the depth values and the amplitude values.

Abstract: Systems and techniques are described herein for determining depth information. For instance, a method for determining depth information is provided. The method may include transmitting electromagnetic (EM) radiation toward a plurality of points in an environment; comparing a phase of the transmitted EM radiation with a phase of received EM radiation to determine a respective time-of-flight estimate of the EM radiation between transmission and reception for each point of the plurality of points in the environment; determining first depth information based on the respective time-of-flight estimates determined for each point of the plurality of points in the environment; obtaining second depth information based on an image of the environment; comparing the first depth information with the second depth information to determine an inconsistency between the first depth information and the second depth information; and adjusting a depth of the first depth information based on the inconsistency.
