1. A distance measuring device comprising:
- a distance measuring sensor for measuring a plurality of regions of an object region and outputting distance data;
a detector for detecting an unmeasurable region within the plurality of measurement regions based on the distance data output from said distance measuring sensor;
a calculator for calculating a spacing on the object corresponding to the unmeasurable region detected by said detector; and
a creator for creating distance data of the unmeasurable region based on the distance data of the measurable region among the plurality of measurement regions and the spacing calculated by said calculator.

Abstract
In the distance measuring device, even if there are unmeasurable distance measuring regions, suitable estimate is set as the distance data of the unmeasurable region in accordance with distance data of the measurable distance measuring regions and the space on the object of the unmeasurable distance measuring region. In this way accurate recognition is possible, for example, when an object is divided by an unmeasurable region, or objects are continuous.
