Abstract

There is provided a signal processing apparatus and a signal processing method enabling correction of a deviation of position information of a dToF sensor. The signal processing apparatus includes: a data acquisition unit configured to acquire a distance histogram that is histogram data of time of flight of irradiation light at a predetermined distance measurement point of a distance measurement sensor; a check target determination unit configured to determine whether or not the predetermined distance measurement point is a distance measurement point as a positional deviation check target; and a coordinate correction unit configured to execute correction processing of correcting three-dimensional coordinates of the predetermined distance measurement point, the three-dimensional coordinates being computed from the distance histogram, on the basis of a determination result of similarity between the distance histogram of the predetermined distance measurement point and the distance histogram of a nearby distance measurement point near the predetermined distance measurement point, in a case where the predetermined distance measurement point is a distance measurement point as a positional deviation check target. The technology of the present disclosure can be applied to, for example, a signal processing apparatus or the like that calculates three-dimensional coordinates of an object by using a distance histogram output from a distance measurement sensor.
