Abstract
The invention discloses a kind of technical method of mobile phone control CCD 3D traverse surveys.The invention is measured for three-dimensional wire, obtains known at least two coordinate points and position first；Then monolithic photography is carried out to target point to be measured using mobile phone control CCD, meanwhile, measure the azimuth in direction to be measured using the electronic compass of mobile phone and put position inclination angle；In addition, it will also be appreciated that the instrument of fixed length line rod length, the focal length of mobile phone photograph, and mobile phone is high；The office work management of traverse survey is finally completed using monolithic photogrammetry principles and Non directional Traverse principle, realizes survey, note, the calculation integration of traverse survey, finally tries to achieve the D coordinates value of unknown point.
Description
First, technical field
The present invention relates to a kind of three-dimensional wire measuring method, particularly a kind of mobile phone control CCD 3D wires survey the skill that note is calculated
Art method.
2nd, technical background
For the traverse survey in mapping operation, conventional method is often using total station survey, spirit level measurement, theodolite
Add steel ruler measurement etc., though measurement accuracy is higher, there is many troubles and deficiency, tool in practical operation and engineering survey
Body is embodied in：
1. tradition mapping instrumentation Capability Requirement is higher, Measure skill professional standards are also higher, it is necessary to are equipped with special
Mapping operations personnel；
2. being measured using traditional instrument of surveying and mapping, carry, remove station inconvenience, consume substantial amounts of manpower and materials, and it is less efficient；
, can only short-term preservation measurement data information 3. traditional instrument of surveying and mapping measures, it is impossible to preserve visual aid for a long time.
Due to photogrammetric development, traditional measurement idea and method is largely changed.We utilize hand
Machine monolithic is photogrammetric, realizes wire three-dimensional measurement works, is very big an innovation and breakthrough, largely solves
The trouble that tradition mapping apparatus measures are brought and inconvenience.
3rd, the content of the invention
It is insufficient existing for conventional wires measurement in order to overcome, now using common monolithic photogrammetric technology, pass through mobile phone
Control CCD camera lenses to carry out monolithic photography, realize that three-dimensional wire measures.
What the present invention was realized in：
Known at least two coordinate points and position are obtained first；Then target point to be measured is carried out using mobile phone control CCD single
Piece is photographed, meanwhile, measure the azimuth in direction to be measured using the electronic compass of mobile phone and put position inclination angle；In addition, also
It is to be understood that the instrument of fixed length line rod length, the focal length of mobile phone photograph, and mobile phone is high；Finally utilize monolithic photogrammetry principles and nothing
Orientation Traverse measuring principle completes the office work management of traverse survey, realizes survey, note, the calculation integration of traverse survey, finally tries to achieve
The D coordinates value of unknown point.
The present invention has advantages below：
1. without specially learning mapping specialty instrumentation, simple measure of learning method and measurement thinking is only needed to complete
Wire three-dimensional measurement.
2. photogrammetric using mobile phone control CCD progress, equipment is light, flexible, reduces substantial amounts of manpower and materials.
3. carrying out traverse survey using mobile phone photographic, the photo of measurement target can be shot, can realize that permanent image is protected
Deposit.
4th, illustrate：
Further illustrate below in conjunction with the accompanying drawings and to this technology method.
Fig. 1 is the route schematic diagram of mobile phone control CCD 3D traverse surveys.
Fig. 2 is the measurement of mobile phone control CCD 3D traverse surveys and resolves principle schematic.
5th, embodiment：
1st, as shown in figure 1, coordinate points A (X explicitly known firstA, YA, ZA) and C (XC, YC, ZC) position, and design from
Known point draws the record form for measuring critical data to the measurement route of tested point；
2nd, mobile phone is set up on some known coordinate point, and measures mobile lens center to the height of ground known coordinate point
h；
3rd, a fixed length line rod is stood vertically on target point to be measured, wherein, line rod length is h0；
4th, the line rod on tested point is aimed at mobile phone, carries out normal case photography, ensure that line rod can occur completely on tested point
The azimuth angle alpha in direction to be measured and the vertical angle of inclination beta to tested point are read in photo, and by mobile phone electronic compass；
5th, as shown in Fig. 2 first, using similar triangle theory, trying to achieve mobile lens center to the oblique of target point to be measured
Away from l, wherein,Secondly, using model 1.Wherein, (Δ X, Δ Y, Δ Z) increases for three-dimensional coordinate
Amount, α is magnetic azimuth, and β is vertical inclination angle；Then, known coordinate point A (X are utilizedA, YA, ZA), by model 2.Wherein, (X, Y, Z) is the coordinate value of unknown point, so that it may seeks the D coordinates value for calculating unknown point；
6th, after the coordinate value for trying to achieve each tested point roughly, carried out according to Non directional Traverse adjustment principle to calculating data
Adjustment converts, and tries to achieve the optimal D coordinates value (X, Y, Z) of each tested point.
