- Title of the invention

Arrangement for automated field tearing in the field measurement

Field of application of the invention

The invention relates to an arrangement for automated field tearing in the field measurement in conjunction with a surveying device that provides measurement data for determining the position and height of any terrain objects.

It can be used as a basis for making or updating maps and enables a high degree of automation from the site survey to the presentation of terrain information in the form of a map or to the use of terrain information in a database.

Characteristic of the known technical solutions

For reasons of automated further processing, including automatic drawing, terrain information, or for the purposes of building digital information storage, there is a requirement that the terrain information (metric and semantic information) must be in digital machine-readable form.

Tachymetric terrain measurement using self-registering computer tachymeters allows the automatic digital storage of metric information (measured values and / or derived quantities), whereas semantic information (information about mutual relationships as well as meaning and valence of terrain points, lines and surfaces) no artificial systems can be identified.

The semantic information is created by humans and recorded in manually drawn, non-scale sketches, the so-called Peldrissen. »

Thus, there is a large discrepancy in terms of the degree of automation between the acquisition of the metric and the acquisition of the semantic information. The known technical solutions have the goal of rationally converting the semantic information acquired in the Peldrissen into a machine-readable form. "

3o, the semantic information acquired in the field crack for the GEOS-1 geodesic surveying system GEOS-1 is numerically described in a separate manual operation using a corresponding input keyboard with visual input control digitized md by means of point numbers linked to the corresponding metric information of a coordinate file ·

The interactive survey and mapping system GEOIiIAP from the company fr'ILD (Switzerland) uses the semantic information gathered during a field survey in a manually guided field survey to digitize it at home on an interactive graphical display, including menu technique, and to provide the semantic information with the metric information giner coordinate file to connect.

For semi-automated digital recording of point-related semantic information in terrain Y / ird in the GDR patent Kr. I46 720 (G 01 C 3/30) proposed a mnemisches compilator, with its help for each Gelandiepunkt recorded the corresponding information in the form of a codeword the measured values is assigned, wherein the code word each digitally constructed with an electronic circuit, displayed and stored machine-readable. In order to generate point bonds and to realize other point or object features by means of a special keyboard on the compiler, in addition to the data stored in the compiler, a graphical representation of the measured points with dot numbering simplified compared to a field outline must be made.

In the patent specification "Arrangement for measurement with a self-registering computer tachymeter", it is proposed to assign to a self-registering computer tachymeter a light modulator, a data acquisition device and a data transmitter and the reflector location a modulation reflector, the mnemonic compiler, a meteorological measuring device, a data receiver and a Peldtisch. The assembly also includes, regardless of the location of the tachymeter and the reflector, an information completer, a data reproducer, and an electronic calculator

The field table consists of a digitally controlled screen, on which the point measured with the computer tachymeter and calculated coordinates is correctly positioned and displays the sheet number of the relevant terrain sector, the fractional parts of the coordinate values and the height of the point. The mapping of the dots is used to produce an almost scale-breaking field, the so-called digital graphic, which in turn has more favorable conditions than an off-scale field crack for the digitization of semantic information.

A radio channel is used for digital information transmission from the tacheometer location to the reflector location. On the radio channel such information is transmitted, which enable the automatic position-correct point display and thus the production of digital graphics on the field table »light is used for digital information transmission from the reflector site to the tachymeter location modulated by the modulation reflector and the evaluation device for light modulation at Tachymeterstandort again digital electrical signals is converted.

Semantic information and current meteorological data on the reflected and light-dark modulated light from the reflector are transmitted to the tachymeter and stored there together with the metric data with the help of the modulation reflector and the integrated module evaluation device for modulated light »For the purpose of domestic perfection of the semantic information every digital graphic on the screen of the computer

Forced completion ♦

The digitally controlled screen and the probe are used to recover the coarse coordinates of characteristic points. The editors scan the points with a probe and use a command keyboard to assign the corresponding semantic information in digital form to the points.

With the aid of an electronic computing device, the information stored in the field in the data memory of the computer tachymeter are combined with the information obtained by the information completer so that the full regional geodetic-cartographic primary information for a database as the basis of further automatic information processing is present.

Both the use of the mnemic compiler alone for the digital encryption of the semantic information according to DDR patent Ir. I46 720 (G 01 C 3/30) as well as the field table in connection with the guidance of a digital graphic in the area and the subsequent domestic improvement of the semantic information with the help of the information completer according to the patent "arrangement for measurement with a self-registering computer tachymeter" the lack of a still a very large proportion of manual operations, combined with a high possible error rate. This also applies to supplementary measurements, which may amount to up to 30% of the total expenditure of a terrain survey, depending on the growth and development of the site.

Object of the invention

The aim of the invention is to completely replace the manual field tearing and home-based implementation of the semantic information contained in the field crack in a digital machine-readable form by an interactive graphical display including the use of the menu technique (Electronic Field Tear), exclusively during terrain measurement and thus achieving higher productivity. At the same time, greater process safety is made possible by checking the completeness of the information collected in sight of the terrain.

Applications:

Use in conjunction with a self-registering computer tachymeter,

- Use in conjunction with an inertial measurement system.

For use in conjunction with an inertial surveying system for terrain measurement, the digital information transfer between recording and display device is eliminated since the electronic field crack is preferably an integral part of the inertial measurement system.

Explanation of the essence of the invention

Starting from the object of the invention, which is to completely replace the manual field ripping and the domestic implementation of the semantic information contained in the field rift in a digital machine-readable form by an interactive graphic display including the use of the menu technique (electronic field rupture) and the electronic To use field rift exclusively during terrain surveying in conjunction with a self-registering computer tachymeter or with an inertial navigation system, it must be noted that all known technical solutions involve passing a manually made (drawn) field rupture to acquire the semantic information during terrain measurement and a second (home) Operation for digitizing the semantic information and assigning it to the metric information The illustrated methods differ essentially in particular from the te technical effort and process safety for the second operation.

The reasons for the great discrepancy between the recording of the metric and the semantic information regarding the automated further processing of the data are due to the fact that the detection of semantic information by humans so far with not enough perfect technical

Means takes place or is provided. So requires'the use

of the geodetic evaluation system GEOS-1 as an ordering feature in the digitization of semantic information the point number. The GEOMAP Interactive Surveying and Mapping System identifies those with metric and semantic information

terrain points to be equipped also with the help of the Punktaummer or by positioning a scanning device on learning point displayed on the screen.

In order to create point connections and associate other point or object features, the mnemonic compiler must be able to use a special keyboard to carry out linking and mapping instructions for the measured points. These operations also require the use of point numbers,

Ils essential shortcoming for the technical solutions requiring the use of the point number for all terrain points and geometric relations derived therefrom (e.g., lines, areas) shows that

the organization of the continuous identical numbering of the same measuring point in the storage medium of the tachymeter and in the Peldriß is complicated and susceptible to failure due to sources of error,

- lobes must also be awarded for features of such objects derived from primary metric data,

- The entry of the point number for connection and assignment commands requires time and allows subjective errors.

Illegal technical solutions have the fundamental principle that the semantic information is to be digitized in a second operation separate from the terrain measurement.

) there are organizational problems if the person responsible for the field cracking has to carry out the digitization of the home or problems of understanding or interpretation if another work force is digitized. In both cases, extra work is required.

The arrangement according to the invention includes an interactive graphic display with menu technology, including the arithmetic and storage capacity associated with the device function, which has the following properties:

  Accurate display of the measured with the computer tachymeter or inertial surveying ground point on the image field of the electronic field crack in such a way that at

At the location of the Gomputertachymeters are a data transmitter and a Datenempfänger-, preferably integrated as an assembly in the total station. At the reflector location are a data transmitter, a data receiver and the electronic field crack.

The need for the mutual transfer of information is eliminated when the electronic field crack is used in conjunction with an inertial measurement system. In this case, the electronic field crack is preferably an integral part of the inertial measurement system.

When measuring the terrain by means of tachymetry, the computer tachymeter is set up ready for measurement as usual, the reflector, which signals a g-end point to be measured, is aimed and the usual * distance and direction measurement is triggered. The determined measurement data are converted in the device-internal computer of the computer tachymeter in position coordinates of the recording system and transfer this information to the electronic field crack »There they are displayed in the correct position on the image field, equipped with the help of the menu technique with the corresponding semantic information and cached in the electronic field crack,

In this way, the terrain section, which corresponds to an image field size, is measured.

In the field measurement by means of inertial measurement system and the preferential integration of the electronic field crisis in the inertial measurement system, the aufzumessende terrain situation is also detected pointwise, but this metric and semantic information in the same operation

obtained with only one device, that is, the transfer of information between the spatially separated recording systems for the metric and semantic information required in the tacheometry ♦

embodiment

The use of the electronic field crack is described below with two examples, the terrain measurement in conjunction with a computer tachymeter and an inertial measurement system.

Example 1: Terrain measurement in conjunction with a computer tachymeter

The entire arrangement consists, according to drawing 1, of an arrangement 1 at the tacheometer location and an arrangement 2 at the reflector location. For arrangement 1 at the tachymeter location, the computer tachymeter 3 includes a data memory 4 and, according to the patent specification "Arrangement for measuring with a self-registering computer tachymeter", an evaluation device for light modulation 5 and a data transmitter 6

 For arrangement 2 at the reflector location include the electronic field crack 7 and corresponding patent "arrangement for measuring with a self-registering computer tachymeter" a modulation reflector 8 and a data receiver 9. The data memory 6 and the data receiver 9 allow the transmission of digital information, in particular information to control the correct images of the current measuring point on the electronic field crack.

The electronic field crack 7 consists of an interactive graphical image field with menu technology including mnemisches Kompilator, as well as from the required for the function of interactive and menu technology computing and storage equipment.

The modulation reflector S allows the transmission of digital information, in particular the semantic information, eccentricities and supplementary measurements from the reflector to the Tachymeterstandort.

In memory 4, the entire information about the terrain to be measured is stored digitally. This information may be used for the purpose of controlling work progress in

233905 4 - ¹⁰ -

retrieved from the sweet sections and made visible on the electronic field crack.

After the determination of the measured values with the aid of the arrangement 1, the point coordinates are calculated in the tachymeter in consideration of the eccentricities and transformed such that they satisfy both the storage in the memory 4 and the control of the display on the image field of the electronic field crack. In the course of the G-e land survey, all the ejection points of the respective image field remain visible. The electronic field crack has sufficient memory technology for this purpose.

The electronic field crack completes the terrain information necessary to build a database or automatically draw a map. "Firstly, it does so through graphical interactive work, in particular to complete the terrain's geometric description (e.g., point connections, area definition). The graphics manipulations are converted by the computer of the electronic Peldrisses into digital information, displayed graphically on the image field, stored in the memory of the electronic field crack and the modulation reflector provided for transmission to the Tachymeterstandort.

Secondly, the menu technique including the mnemonic compiler is used to input and digitize eccentricities and the remaining semantic information. The result of the input is also displayed graphically or alpha-numerically on the screen, stored in memory and provided for transmission of information to the tachymeter site.

The functions of the interactive graphic image field and the menu technique are usefully combined in the digitization of the semantic information, e.g. Surface connections can be established and assigned to the associated object features using the menu technique.

In order to check the progress of the work, either arbitrary, already measured terrain sections on the image field can be made visible at different scales both from the memory 4 and from the image repeat memory of the electronic field crack.

23 9 9 05 4

After completion of the measurement of the points to be recorded with the tachymeter or in the meantime, the electronic field crack is used to enter supplementary measurements. The measurement results are entered via the keyboard of the mnemonic compiler and made visible on the interactive image field.

After the visual comparison of the field survey (terrain visual model) visualized on the image field with the final visual control, the digital terrain information corresponding to the graphical terrain model is transferred from the reflector location to the tachymeter location memory 4. The metric information obtained by the total station and the Digital semantic information and supplemental measurements obtained from electronic field cracking represent a complete digital terrain model. This model can be used for a variety of purposes, primarily for automatically drawing a map or building a database.

Example 2: Terrain measurement in conjunction with an inertial surveying system

The arrangement consists of an inertial measurement system, the electronic field crack and a data memory. Compared to the field measurement in conjunction with a computerized tachymeter (example 1) eliminates all technical facilities for data transmission, since the entire arrangement is transported in the form of an integrated device system from measuring point to measuring point.

The inertial measurement system continuously determines the information on the position and height determination of any terrain point and calculates its coordinates. The coordinates are stored in the data memory and serve to display the point on the image field of the electronic field crack. The completion of the terrain information by the semantic information proceeds as indicated in the first example.
