Distance measuring apparatus capable of measuring plural distance data for calculated angle ranges |
摘要 |
In a distance measuring apparatus, a large number of distance data within a certain calculation angle region are acquired so as to obtain distance data with high reliability. The distance measuring apparatus is comprised of: a transmitter/receiver device including at least one of a transmitter for projecting electromagnetic waves while scanning the electromagnetic waves, and a receiver for receiving reflection waves of the electromagnetic waves reflected from an object while scanning the reflection waves; an angle detecting apparatus for detecting at least one of an angle when the electromagnetic waves are projected and an angle when the reflection waves are received; a distance calculating apparatus for calculating a distance up to the object corresponding to the angle based upon a relationship between the electromagnetic waves and the reflection waves, and for using a calculation result as detection data; and a data processing apparatus for acquiring distance data in a calculation angle region corresponding to a plurality of the distance calculations based upon the detection data obtained during a plurality of distance calculations.
