Described range unit effectively measure distance, to improve certainty of measurement.
Concrete, the travel distance of described range unit is exactly actual measurement distance, but due to a variety of causes,
The straight line measuring route not necessarily standard of described range unit, sometimes runs into barrier and must bypass
Barrier just can measure so that actual route of measuring is curve, and actual measure distance more than actual away from
From.And the actual range between two places is the air line distance between two places.
Based on above-mentioned, the range unit of the embodiment of the present invention uses the mode of distance correction, utilizes described range finding
Angle between direct of travel and the reference direction of device, measures distance (namely travel distance) to reality
It is modified, effectively to be measured distance.And described reference direction is usually the craspedodrome between two places
Direction, when measuring the distance between two places along described reference direction, can obtain more accurate
Two places between actual range.
In embodiments of the present invention, described distance correction unit is specifically for utilizing formula L=Scos θ to calculate institute
That states range unit effectively measures distance；
Wherein, L is for effectively to measure distance, and S is travel distance, and θ is angle.
So, by the travel distance of described range unit is projected to reference direction, can obtain in described ginseng
Examine and effectively measure distance on direction, improve certainty of measurement.
In the specific embodiment of the invention, described range unit also includes display unit, described display unit with
