ROTARY TYPE DISTANCE ESTIMATION APPARATUS AND MOVING BODY INCLUDING THE SAME
First Claim
1. A rotary type distance estimation apparatus comprising:
- a signal transmission unit transmitting a signal for measuring a distance to an obstacle;
a signal reception unit receiving the signal reflected by the obstacle;
a distance calculation unit calculating the distance to the obstacle by processing the received signal;
a rotation unit rotating a direction of the signal transmitted from the signal transmission unit; and
a determination unit determining the direction of the signal within a predetermined angle range according to what number of times the received signal matches based on a rotation angle per sampling of the signal.
