Description
Technical field
The invention belongs to the engineering measuring technology field, be specifically related to a kind of mutual conversion method of measuring between coordinate and construction coordinate.
Background technology
Traditional buildings locating measurement method is: the measurement coordinate that directly uses designing institute to provide carries out testing, all there is certain included angle in the longitudinal and transverse between centers of measuring coordinate and buildings generally speaking, in the setting-out process, often to calculate the position angle and the distance of point-to-point transmission, guarantee that to check data are accurate, amount of calculation will be very big like this, will certainly cause certain adverse effect to the accuracy of data.
Therefore, be necessary to develop a kind of novel building locating measurement method.
Summary of the invention
Technical matters to be solved by this invention is: a kind of mutual conversion method of measuring between coordinate and construction coordinate is provided, so that reduce amount of calculation, improves the accuracy of buildings location survey data.
The present invention solves its technical matters and adopts following technical scheme:
Mutual conversion method between measurement coordinate provided by the invention and construction coordinate, specifically: the Design Orientation measurement coordinate that obtains buildings earlier by designing institute, needing the measurement coordinate of setting-out all to convert all with computer by Excel software again comes, in measuring all conversion processes of coordinate, need to utilize the construction coordinate system conversion formula, utilize the construction coordinate system conversion formula will measure coordinate conversion and become the coordinate parallel with vertical with buildings, by this coordinate system 2 distance calculation is become very simple fast, because no matter 2 is on a longitudinal axis or same transverse axis, the position angle must be 0 °, 90 °, 180 °, a kind of in 270 °, with on the longitudinal axis or the transverse axis 2 (A, it is identical B) value being arranged necessarily in the value.Data after the conversion are being checked just to be defined as construction coordinate after errorless, utilizes this construction coordinate to carry out setting-out then.
Described construction coordinate system conversion formula is:
A＝(X-X
0)·cosα+(Y-Y
0)·sinα
B＝(Y-Y
0)·cosα-(X-X
0)·sinα
In the above-mentioned formula: X and Y are respectively the measurement coordinate figure that designing institute provides, and are known; X
0And Y
0Coordinate figure by unit in charge of construction oneself determines is used to adjust the positive negative value of coordinate, is known; A and B are the construction coordinate value of obtaining.
Because there is subtraction in the formula, therefore can produce negative value and make troubles for fear of the B value to setting-out work, adjust coordinate points (X so introduce positive negative value
0, Y
0), can elaborate below.
Mutual conversion method between above-mentioned measurement coordinate provided by the invention and construction coordinate, the location survey that it is used for newly-started buildings or old building and meets other any situations of this method condition.
The present invention and traditional buildings locating measurement method comparison have following major advantage:
One. reduced calculated amount: coordinate conversion is become the construction coordinate parallel with vertical with buildings, just can calculate on the coaxial cable 2 distance size very fast (because the A or the B of two point coordinate values on the coaxial cable are identical by coordinate figure, the size of distance equals the difference of different B of coordinate figure or A value), no matter 2 is on a longitudinal axis or same transverse axis, the position angle must be a kind of in 0 °, 90 °, 180 °, 270 °, very directly perceived, significantly reduced calculated amount.
They are two years old. and easy to use: that a kind of coordinate conversion formula that is used for the buildings location survey is provided, because this conversion formula configures in advance, and be general unconditional restriction, can utilize Excel software to need the measurement coordinate of setting-out all to convert all before setting-out in computer comes, after verification of data is errorless, directly utilize construction coordinate to get final product relieved setting-out.
Increase by one and with buildings the point position of relativeness is arranged as interim in the setting-out process, we can be according to the coordinate points nearest with buildings, by relativeness very fast extrapolate the newly-increased construction coordinate value of putting, get final product setting-out.
If do not change, that reckoning and checking computations are got up and have just been bothered very much.
Therefore the value of construction coordinate is very big, and it can bring immeasurable contribution to engineering survey work.
They are three years old. improve the data accuracy rate: carry out inverse by himself distinctive anti-checking computations function of coordinate transformation method and check, can improve data rate of accuracy reached to 100%.
Illustrate: A=(X-X
0) cos α+(Y-Y
0) sin α
B＝(Y-Y
0)·cosα-(X-X
0)·sinα
(X, Y) for the measurement coordinate figure that designing institute provides is known, (X
0, Y
0) can determine by oneself, be used to adjust the positive negative value of coordinate, equally also be known.Can obtain like this construction coordinate value (A, B), again with each coordinate figure of asking (A, B) bring in the inversion formula respectively:
X＝A·cosα-B·sinα+X
0
Y＝B·cosα+A·sinα+Y
0
Obtain that (the construction coordinate value of coming as the then explanation institute conversion that conforms to initial value must be correct for A, original coordinates value before conversion B), otherwise the wrong result of calculation of explanation transfer process is unavailable, palpus debugging correction or recomputate.
In a word, X, Y-axis and the buildings that the present invention can eliminate measurement coordinate system be the angle between axis in length and breadth, the A, B axle that makes the construction coordinate system after the conversion respectively with buildings axis keeping parallelism or vertical (90 ° of angles) in length and breadth, the relativeness of some interdigit is very directly perceived.The distance of point-to-point transmission can directly be tried to achieve by the numerical difference between of construction coordinate system A axle or B axle, i.e. the absolute difference of A1-A2 or B1-B2, and preceding 2 distance: D convert
2=(X1-X2)
2+ (Y1-Y2)
2Computing formula is simplified greatly, and not only computing velocity is fast, has also improved the accuracy of result of calculation simultaneously.
