DISTANCE MEASURING APPARATUS, DISTANCE MEASURING METHOD, NON-TRANSITORY RECORDING MEDIUM, AND AUTOMATIC PARKING CONTROL METHOD

A distance measuring apparatus according to the present disclosure includes: a detector that detects, in a graph, a local maximum point of a received wave intensity of a reflected wave resulting from reception of an ultrasonic wave that has been transmitted and then reflected by an object, the graph indicating a relationship between the received wave intensity and a time of flight of the ultrasonic wave; and a distance measurer that calculates, when a plurality of the local maximum points is present within a range in which the received wave intensity is equal to or greater than a predetermined threshold in the graph, a distance to the object based on the time of flight at a local maximum point whose received wave intensity is lowest among the plurality of local maximum points.
