Assignee: VC INC.
Field: Measurement (Instruments)
Classification: CPC G  A | IPC A  G

Claim 0:
1. A distance measuring apparatus comprising:
an output unit configured to output information;
a memory configured to store map information of golf courses;
a location acquiring sensor configured to acquire a current location;
a distance measuring sensor configured to measure a distance to a target;
a slope sensor configured to measure a tilt angle;
an azimuth sensor configured to measure an azimuth of the target; and
a control unit configured to read map information of the golf course corresponding to the current location from the memory, to calculate a first distance from the current location to a first point on the golf course by using the map information, to calculate a horizontal distance to the target by using the distance to the target and the tilt angle, to determine whether the horizontal distance is within the first distance, to determine whether the azimuth is included in a range between a first azimuth in a direction connecting a second point of the golf course from the current location and a second azimuth in a direction of connecting a third point of the golf course from the current location, and to output the horizontal distance to the output unit when the horizontal distance is within the first distance and when the azimuth is included in the range between the first azimuth and the second azimuth,
wherein the second point of the golf course and the third point of the golf course are different from a point of the target.
