Abstract
The method of distance between the two places for thering is barrier to be separated by the present invention relates to a kind of accurate measurement, on A ground, the side of D ground two places line is provided with and A ground, the accessible B mark points in D ground two places, on A ground, the opposite side of D ground two places line is provided with and A ground, the accessible C flag point in D ground two places, C flag point, B mark points, A ground is in same level and B mark points with D, D ground is conllinear with C flag point, using the distance between laser range finder measurement B mark points and A ground, the distance between C flag point and A ground, the distance between B mark points and D ground, the distance between C flag point and D ground, with then can be calculated A and D ground the distance betweene.Measuring method of the present invention, without measuring any angle again, measuring process simplifies, and measurement efficiency is high, and measuring accuracy is high, and measurement error is small, is adapted to be used in mountain shape is analyzed and is surveyed and drawn.
Description
Technical field
There is the two places spacing that barrier is separated by the present invention relates to mountain shape analysis technical field, more particularly to a kind of accurate measurement
From method.
Background technology
In mountain shape analysis and mapping process, it is often necessary to the air line distance between two places is measured, due to actually measuring
Cheng Zhong, physical features distribution is often extremely complex, it is necessary to through being commonly present barrier, laser range finder and ultrasonic wave between the two places of measurement
Rangefinder cannot direct measurement obtain a result.
It is conventional at present to put mark point accessible between and two place to be measured by means of in two place to be measured peripheral hardware,
From its angle the distance between with two place to be measured and between mark point and two place to be measured of mark point measurement, then borrow
The distance between two places to be measured are drawn by helping the cosine law.But, due to need measurement markers point and two place to be measured it
Between angle, not only need the protractor for preparing to measure angle in addition again, and surveyed by cosine triangle and asked again after angle
Distance, easily amplifies the error of angle and is delivered to range measurement the inside, and the bad control of measurement of angle easily causes measurement error
It is bigger than normal.
The content of the invention
The present invention is in view of the shortcomings of the prior art, there is provided a kind of accurate measurement has the two places spacing that barrier is separated by
From method, concrete technical scheme is as follows：
, there is barrier between A ground and D ground, in A in a kind of method that accurate measurement has distance between the two places that barrier is separated by
Ground, the side of D ground two places line is provided with the B mark point accessible with A ground, D ground two places, in A ground, D ground two places line
Opposite side is provided with the C flag point accessible with A ground, D ground two places, and B mark points, D ground and C flag point are conllinear, using laser
The distance between stadia surveying B mark points and A ground is a, using the distance between laser range finder measurement C flag point and A ground
It is b, is c using the distance between laser range finder measurement B mark points and D ground, C flag point and D is measured using laser range finder
The distance between ground is d, then the distance between A ground and D ground are e,
Beneficial effects of the present invention：In measuring method of the present invention, without measuring any angle again, significantly simplify
Measuring process, measurement efficiency is significantly improved, and simply measures at the distance between 2 points using laser range finder in measurement process, most
The result accuracy for drawing afterwards is high, and method error of measuring of the present invention is small, easy to operate, is adapted to analyze and survey and draw in mountain shape
In use.
Brief description of the drawings
Fig. 1 is measuring method Mathematical Modeling schematic diagram of the present invention.
Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
As shown in figure 1, Fig. 1 is measuring method Mathematical Modeling schematic diagram of the present invention.Exist and D ground between due to A
Barrier, thus A ground and D ground the distance between directly can not be measured with laser range finder.
The side on A ground, D ground two places line is provided with the B mark point accessible with A ground, D ground two places, on A ground, D ground
The opposite side of two places line be provided with A ground, the accessible C flag point in D ground two places, due to B mark points, D and C flag point
Three point on a straight line, thus C flag point, B mark points, A ground and D be in same plane, that is to say, that measurement side of the present invention
Method is applied to any physical features, and same level is respectively positioned on without C flag point, B mark points, A ground and D, significantly simplifies measurement step
Suddenly；Add, effect is implemented on determination B mark points, D ground and C flag point three point on a straight line by being measured using laser range finder quickly
It is really good；It is a using the distance between laser range finder measurement B mark points and A ground, C flag point and A is measured using laser range finder
The distance between ground is b, is c using the distance between laser range finder measurement B mark points and D ground, is surveyed using laser range finder
The distance between amount C flag point and D ground are d；Due to C flag point, B mark points, A and D be in same level and B and mark
Note point, D ground and C flag point are conllinear, therefore A ground, B mark points, C flag point constitute △ ABC.
In Fig. 1, due to cos ∠ ADB+cos ∠ ADC=0, i.e.,Setting e1 2=
a2-c2, e2 2=b2-d2, you can obtainThat is e2It is e1 2And e2 2Weighted average, weight be respectively d and
C, the formula also facilitates memory, is easy to field to implement measuring and calculating.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, it is all in essence of the invention
Any modification, equivalent and improvement made within god and principle etc., should be included within the scope of the present invention.
