Abstract
The present invention is the technical method of a kind of portable super-station instrument measurement object height and width.Firstly, carrying out field process using photography super-station instrument, the photo of vertical object is obtained, and obtain following data: the horizontal distance △ Y of the vertical object of inclination angle ω, distance of camera lens；Then, interior industry is carried out using Digital Photogrammetric System to handle, obtain vertical object picpointed coordinate in photograph；Around X-axis, there are inclination angle ω when considering photography, and therefore, it is necessary to photographic rectifications, and it is constant in the coordinate value variation that this side up to carry out X-axis；Above formula and known quantity are derived and are calculated the width direction and short transverse coordinate of object any place；Finally, the data that field operation is obtained substitute into the formula that interior industry derives, the width di of object any place and the height hi of any place can be obtained.
Description
One, technical field
This method belong to it is photogrammetric it is middle using the portable super-station instrument single-phase vertical object any place height of measurement and
Width method.
Two, technical background
The height and width of object any place are two important measurement factors in photogrammetric observation.Width is led at present
It wants measurement method using graduated scale hand dipping, belongs to contact type measurement, due to landform, the influence of understory shrub, with measuring sample
Interior object is time-consuming and laborious, and a people is needed to measure, people record, and human cost is higher.Elevation carrection is measured using altitude meter,
The problems such as being difficult to accurate judgement there are object vertex, causes measurement error larger, and need two people cooperation, measurement efficiency compared with
It is low.
Therefore, many troubles and error are inevitably brought using traditional instrument measurement in measurement process.This item
Mesh realizes that object is appointed in sample ground by monolithic right photographic measurement method under any orographic condition, using portable super-station instrument
The measurement of height and width at meaning, it is fast to measure speed, only a people is needed to can be completed, can be with behind with obtaining sample photograph and inclination angle
Carrying out interior industry interpretation, processing by the Digital Photogrammetric System of independent research, the sample trees diameter of a cross-section of a tree trunk 1.3 meters above the ground and tree are high with can be obtained sample, and measure
Value can be with persistence.The General Promotion speed of data processing, intelligence degree.
Three, summary of the invention
Portable super-station instrument is applied in this research, and measurement is not accessible and is difficult to the vertical object closely surveyed, for example, beacon,
Flagpole, trees etc..The good photography super-station instrument of calibration is placed on holder, and is connect with tripod, air-bubble level tune is passed through
It saves instrument and keeps horizontal, then, using monolithic right photographic measurement method, photograph and inclination angle are obtained, by establishing object coordinates
Mathematical model conversion between image space coordinate obtains vertical object any place height and width.
Firstly, carrying out field process using photography super-station instrument, the photo of vertical object is obtained, and obtain following data:
The horizontal distance △ Y of the vertical object of inclination angle ω, distance of camera lens；
Then, interior industry is carried out using Digital Photogrammetric System to handle.Vertical object object space coordinate in space are as follows:
(Xs,Ys,Zs)；Vertical object picpointed coordinate in photograph are as follows: (u, f, v)；In Digital Photogrammetric System, object space coordinate
With picpointed coordinate ratio formula are as follows:Around X-axis there are inclination angle ω when in view of photography, therefore, it is necessary to photographs to entangle
Just, the X-axis constant formula and spin matrix used in the coordinate value variation that this side up are carried out are as follows:WithAbove formula and known quantity are derived and are calculated the width side of object any place
To with short transverse coordinate are as follows:
Finally, the data that field operation is obtained substitute into the formula that interior industry derives, the width of object any place can be obtained
The height hi=△ Z of di=△ X and any place.
Four, Detailed description of the invention:
The present invention is further described with example with reference to the accompanying drawing.
Fig. 1 is vertical object object space coordinate in space.Fig. 2 is picpointed coordinate in vertical object photograph.Fig. 3
It is the operation schematic diagram that vertical object photo and data are obtained using photography super-station instrument with Fig. 4.
Five, specific embodiment:
1, field process is carried out using photography super-station instrument, obtains the photo and data of vertical object.
2, interior industry is carried out using Digital Photogrammetric System to handle, obtain the picpointed coordinate of vertical object any place in photo.
Around X-axis, there are inclination angles when in view of photography, therefore, are corrected to the photograph of acquisition using formula and spin matrix.Then, it pushes away
Lead and be calculated the width direction and short transverse coordinate of object any place.Finally, the data substitution that field operation obtains is pushed away
In the formula led, the width and height of object any place are obtained.
Claims (2)
1. the technical method of a kind of portable super-station instrument measurement object height and width, it is characterized in that: firstly, super using photography
Instrument of standing carries out field process, obtains the photo of vertical object, and obtain following data: the vertical target of inclination angle ω, distance of camera lens
The horizontal distance △ Y of object；Then, interior industry is carried out using Digital Photogrammetric System to handle.
2. according to claim 1, the algorithm of a kind of CCD photography super-station instrument measurement object height and width, it is characterized in that: vertically
Object object space coordinate in space are as follows: (Xs,Ys,Zs)；Vertical object picpointed coordinate in photograph are as follows: (u, f, v)；
In Digital Photogrammetric System, object space coordinate and picpointed coordinate ratio formula are as follows:Around X when in view of photography
Axis is there are inclination angle ω, therefore, it is necessary to photographic rectification, carry out the constant formula used in the coordinate value variation that this side up of X-axis and
Spin matrix are as follows:WithWherein, (u ', f ', v ') is the picpointed coordinate after correcting；
Above formula and known quantity are derived and are calculated the width direction and short transverse coordinate of object any place are as follows:Finally, the data that field operation is obtained substitute into
In the formula that interior industry derives, the width di=△ X of object any place and the height hi=△ Z of any place can be obtained, wherein
Δ X is horizontal direction any two points X-coordinate difference, and Δ Z is vertical direction any two points Z coordinate difference.
