Description

Integrated management system for gathering topographic data which can handle data measured by total station}

The present invention relates to a geodetic survey data integrated management system, and more particularly, to a geodetic survey dedicated integrated management system that can collect and process data surveyed by a total station that is a surveying equipment.

In the past, when equipment was not developed, a surveyor surveyed the area by triangulating the area, measuring the distance with a tape measure, accumulating the data, and plotting the ground based on the data. The whole map is complete.

In recent years, aerial photography can be used to see a wide range of areas directly, and aerial photographs can be taken from different angles with some overlap, and then analyzed and processed to obtain two-dimensional and three-dimensional coordinates for each point in the target area. have. In particular, by operating the optical range finder rider (LIDAR), which scans the laser pulses and detects the reflected light together with aerial photography, the 3D coordinates of the target point are less laborious and faster than the conventional method through the digital elevation model. The method of obtaining is used. The three-dimensional coordinates thus obtained can be used to create a three-dimensional digital map such as a three-dimensional topographic map.

On the other hand, unlike aeronautical maps, there are many methods of making a three-dimensional digital map using GPS, which basically receives a carrier from at least four GPS satellites over the earth and knows its exact location and time. If so, the distance between these satellites and the GPS receiver can be calculated, and the 3D location information of the GPS receiver can be found. Therefore, the GPS 3D location information of each area of the target is collected and a 3D digital map is created.

However, aerial photographing to obtain aerial photographs is expensive, and therefore, it is difficult to frequently perform aerial photographing to reflect changes in terrain or features, and on the other hand, high-resolution cameras in urban areas where high-rise buildings are concentrated. Even when shooting the ground, the perfect flatness cannot be captured due to the crowded ground and optical limitations such as the curvature and angle of the camera lens. In order to solve this problem, a variety of facial expressions have to be done, which also requires a lot of time and effort, and still completeness is limited.

In addition, the method of making a digital map using GPS is limited in accuracy due to some well-known error factors, and GPS surveying itself is impossible if the position of the GPS receiver cannot see the open sky so that the satellite can be well-oriented. It is likely to cause an error. Some survey targets are difficult to take the GPS receiver there and make measurements directly.

One way to increase this limited accuracy is by complementary surveying with survey instruments. Surveying equipment, called total stations, is an electronic ranging and measuring device in which electronic theodolite and electro-optical instruments (EDM) are integrated into a single device. It consists of four elements: a vertical angle detector, a horizontal angle detector for measuring the horizontal angle caused by the left and right rotation of the main body, a distance measuring unit for measuring the distance from the center of the main body to the prism, and a tilting sensor for measuring and correcting the horizontal of the main body. .

In the past, the total station was not equipped with its own central processing unit or storage device for processing measured data. However, due to the development of the electronics industry, a computer or a dedicated device does not occupy a large space. In addition, a processing apparatus that can determine the position coordinates by immediately analyzing the data surveyed by the total station in the field is also widely used.

As a result, in order to efficiently obtain and maintain survey results such as topographic maps and various digital maps, it is necessary to flexibly combine and use various survey methods rather than adhere to any specific survey system.

However, the total station survey result data may have a different format and survey system by reflecting an operating system program running its own central processing unit adopted by the total station and an application program for processing surveys and measured values. Centered angle and distance-based data may not be compatible with each other in the format of the survey system, such as latitude, longitude, and altitude produced by GPS surveys. It also depends on which model the Earth ellipsoid is based on.

If the format and system of survey data are not unified, a system that organizes, integrates and manages the entire survey data including the total station may become difficult to operate.

Therefore, despite the differences between the manufacturer of the total station, the operating system and the application program, and the survey system used as the basis of the survey, the actual data obtained through the total station is combined with the results of the GPS survey and the aerial survey. To create a complete digital map and to keep changes over time updated at a low cost in a short time, a management system is required to operate the survey data in an integrated and unified manner.

On the other hand, when actual surveying is performed with the total station for integrated management, the surveying is often performed for many points. In areas with limited areas, such as when designing or verifying and modifying a specific part of a road, you can do this for some time, but you may want to survey a large number of survey points that span a relatively large area. Doing so is too time-consuming and expensive to move and set up the surveying equipment, so improvements are needed.

It is desirable to be installed at one position and installed at an angle that is easy to collimate at the expected total station position. Buildings may be used in the city center as a feature that reflectors are installed, but in the outskirts, roadside facilities such as telecommunication poles, transmission towers, and streetlights may be used.

The tilting sensor, which measures and corrects the body's level at the total station, can automatically level the body using electronic bubbles.The centrifuge is mainly a laser centrifuge, which is mounted on the vehicle. Look down through the confirmation window so that the total station body is directly above the survey reference point. To ensure that the total station's body matches the survey reference point and the coordinates are large, move the vehicle itself or the total station loading bin, but when the errors are small, the camera is installed with a centripetal device and interlocked with mechanical devices such as coordinate adjustment tables. To move the position to the correct coordinates.

The terminal computer device of the present invention can exchange information with the central computer of the information center by using a wireless communication means, so that if there is no program required for conversion in the conversion module or there is no necessary reference data, the terminal computer device can be used to bring it from the central computer. have.

Elements such as a correction module reflecting in may be provided together with the terminal computer system, but it may be desirable to store, install and share in a central computer rather than them.

Although total stations can draw drawings directly using survey-specific CAD programs, they usually store only survey data and transfer them to a central computer, or transfer them to a temporary storage device, and implement them as cads from a central computer, print out maps, or analyze the drawings. Will be able to.

In addition, in the present invention, the survey data of the total station can be transmitted to the central computer at regular time intervals so that the central information center checks the numerical value abnormally and instructs further detailed investigation of the singularity immediately before the vehicle returns.

The central computer 10 includes a numerical information database having numerical information constituting a ready-made numerical map, and data transmitted from the terminal computer device 20 of the survey information collection vehicle in charge of each region by time and region (vehicle). When the measured information of the collected information database and the collected information database are compared with the numerical information of the numerical information database, and there is a difference over a certain level, the survey information is used to correct the numerical information of the numerical information database based on the priority. A correction processing module and an image processing module for processing the numerical information of the numerical information database into a digital map are provided.

Each database may be implemented as a concept that includes programs stored and used in the storage device 13 provided in the central computer 10 and data stored therein. It can actually be implemented in combination with a processing unit (CPU) 11.

The central computer 10 includes a communication unit 12 for contacting the terminal computer device 20 operated in the vehicle 50, an input device 16 for inputting commands and information, a printer device 17 and a monitor as an output device. (15) is provided.

The terminal computer device 20 mounted on the vehicle 50 may be difficult to distinguish from the total station 30 in terms of mechanical space due to a combination of various functions for improving the performance of a recent total station. A computer unit placed in 512, which is conceptually a central processing unit (CPU) 21, storage unit 23 and its built-in program, monitor for the terminal computer unit excluding the original setting and measurement function of the total station 30. (25), various input devices 26 and communication devices 22. FIG. The terminal computer device 20 is coupled to the total station 30 mounted on the trailer 54 of the vehicle by short-range wireless communication such as a wired or Bluetooth communication for surveying the total station 30 through a remote control module. You can adjust the survey angle for setting and collimation, and store and store the surveyed data.

Therefore, the body 52 of the vehicle 52 can be manipulated so that the setting and angle adjustment of the total station 30, focus confirmation, surveying, and measurement data storage can be performed without the need of the surveyor. For this manipulation, the terminal computer device 20 is provided with an input device 26 such as a keyboard, a mouse or a joystick, and a remote control module including software such as a remote control program for controlling the total station 30. In the remote control module, a signal capable of actually driving each operation unit of the total station 30 is eventually transmitted to the total station 30.

In addition, the total station 30 includes at least one conversion program for converting the three-dimensional position information made of the various data types surveyed to the data format of the three-dimensional position information forming the digital map database of the central computer 10 A conversion module and a recruitment information database for organizing three-dimensional position information newly recruited in the target area and converted through the conversion module for each recruitment time point are provided.

The total station 30 is an electronic measuring and measuring device incorporating electronic theodolite and electro-optical instruments (EDM), which is already known as an instrument part having a function of actual measurement. Vertical angle detector 33 for measuring the vertical angle caused by vertical movement, horizontal angle detector 35 for measuring the horizontal (azimuth) angle caused by left and right rotation of the main body, and distance for measuring the distance from the center of the main body to a prism or an arbitrary object. It is equipped with four elements of the measuring unit 31, the tilting sensor 37 for measuring and correcting the horizontal level of the main body, and specialized in this function consists of hardware and software or a combination thereof, and when collimating near the prism, the center of the prism Auto focus module for precisely collimating focal points, and automatic sphere to automatically match the reference point coordinates with the total station body when centering It may include an automatic setting module for automatically leveling the total station body, including a shim module, an electronic bubble, and a tilting sensor.

Function-specific hardware typically consists of a control board (39) and function buttons integrated in a total station, and the controller board (39) has its own processor, temporary storage and accessory circuits that are specific to a particular function. It can be made with. It may include a communication means not shown in its input and output unit for connecting to other devices.

In the configuration of this embodiment, the communication device 22 of the terminal computer device 20 can exchange information with the central computer 10 of the information center by using a communication network 70 such as a mobile communication network and the Internet, thereby converting If a module does not have a program required for converting position data or there is no reference data required, the module can be taken from the central computer 10 and used. Through such a configuration, the terminal computer device 20 of the present invention can be specialized in collecting location information data by geodetic surveying and can be operated as a lighter system, thereby increasing operational efficiency.

Elements such as a correction module that determines the priority among the 3D location information of the digital information database or the collection information database including the 3D location information for constructing the digital map and reflects the 3D location information of the digital map database Tool for storing and installing in the central computer 10 in order to increase the operational efficiency of the terminal computer device 20, and having a total program of cad program for drawing drawing, printing out a map, or drawing analysis. tool) is also installed in the central computer (10).

In addition, in this embodiment, the survey data of the total station 30 is transmitted to the central computer 10 at regular time intervals to immediately check the numerical value at the central information center and to perform further detailed investigation of the singularity immediately before the vehicle returns. Can be directed.

For the instant check, the data system and the surveying system of the total station 30 correspond to the data system and the surveying system of the central information center. This data conversion process is performed by the conversion module, and the converted data is transmitted through the central processing unit 21 and the communication device 22 of the terminal computer device 20 once stored in the recruitment information database.

When the GPS receiver 40 receiving the GPS satellite signal is installed in combination with the total station 30, the antenna 41 is preferably installed at the upper part of the main body of the total station 30 so that the coordinates of the main axis of the main body coincide with each other. . The GPS receiver 40 also includes a modem for transmitting and receiving error correction signals to and from the reference station GPS receiver 45 so as to give the machine point data of the total station 30 in real time. The three-dimensional position information acquired by the GPS receiver 40 is transmitted to the terminal computer device 20 mounted on the vehicle body 52 in the form of machine point coordinates used for surveying the total station 30 using a conversion module. It may be converted or converted through a processor installed in the GPS receiver 40 itself and directly input to the total station 30.

Dividing the whole country into several regions, each vehicle is equipped with a vehicle equipped with a terminal computer device 20, a GPS receiver 40 and a total station 30 among the systems of the present invention, and for regular data updates or as necessary. Perform the required surveying while moving this vehicle.

By mounting the total station 30 in the vehicle 50, it is easy to move, and it is possible to cover a wider survey area than in the prior art. In addition, the GPS receiver 40 is mounted together, and the GPS receiver 40 includes a modem for transmitting and receiving an error correction signal to and from the reference station GPS 45, which is an electronic reference point, so that the RTK (Real Time Kinematic) GPS alone is provided. The position of the current total station 30 can be ascertained by a few tens of millimeters of error, which is higher accuracy than operating GPS. In addition, since the same single GPS receiver 40 and the total station 30 cover a relatively large area, geodetic surveying is performed in an unchanged environment, and location information is obtained so that there is no equipment factor error between the location information. have.

Hereinafter, the process of collecting the survey information using the total station 30 in the present invention will be described in more detail. First, the total station 30 is mounted on the vehicle trailer 54. The total station 30 is provided with a GPS receiver 40. The antenna 41 of the GPS receiver 40 is installed coaxially with the central axis of the main body of the total station 30 and is installed to match the coordinates.

The trailer 54 on which the total station is loaded has a form distinguished from the vehicle body so that vibration of the vehicle body 52 is not transmitted. The trailer 54 and the vehicle body 52 are not rigidly connected but are connected by a flexible link. In the trailer 54, the connection portion with the vehicle body 52 is provided with a hydraulic lifting type 56 for supporting the trailer 54 without moving by manipulating the vehicle body 52 when the vehicle is stopped and descending to reach the ground. do. Although not shown, the top plate 57 of the trailer 54 to which the total station holder is fixed may be made of an anti-vibration table using a tube or a spring to absorb fine vibrations.

Accordingly, in the system of the present invention, the vehicle 50 equipped with the total station 30 approaches near the position where the surveying object is located, stops the vehicle once, and operates a button installed on the vehicle body 52 to operate the trailer 54. It is fixed to the ground by the hydraulic lifting pedestal 56 so that a slight vibration of the vehicle body 52 does not affect the trailer 54. This can be done similarly to the bottom fixation in the vehicle movement train but can be made relatively simple since it does not handle the weight.

The total station 30 is set for the survey. The total station setting is to prepare for surveying, and to level the total station body using the electronic bubble and tilting sensor 37. In addition to a sensor that detects the level to automatically level the main body, the drive means for holding the posture of the base of the main body of the total station while rotating with a precision motor about an axis extending in the front and rear directions and an axis extending in the left and right directions and these drives An automatic setting module including software for adjusting the driving means in association with the means and the sensor may be provided.

Meanwhile, the GPS receiver 40 detects the position of the point where the total station 30 is placed, that is, the mechanical point. The mechanical points represent the latitude, longitude, and altitude from the geoid plane of the earth ellipsoid in the GPS system, but are converted to azimuth and distance from the reference point, the coordinates available to the total station 30 for total station surveying.

When the setting is made and the mechanical point is confirmed, the azimuth and altitude or vertical angle on the horizontal plane are adjusted to collimate the object with the telescope of the total station to measure the distance and angle to the object.

Such a series of operations can be performed in the vehicle body 52 by the operator who performs a survey. Therefore, while the survey worker directly moves the vehicle 50, the vehicle stops at a position where it is easy to survey the survey target, and performs a survey. For in-vehicle work, the total station 30 itself must be equipped with a system capable of remote control.

For example, a camera for observation of an object is installed in the alternative lens portion of the telescope, so that the surveyor in the vehicle can observe the object through the telescope through the monitor 25 of the terminal computer device 20. Make it visible. In addition, a vertical angle adjusting motor is installed in the vertical axis detecting unit 33 around the rotating shaft for adjusting the vertical angle of the telescope for measuring the vertical angle, and a horizontal angle adjusting motor is installed in the horizontal angle detecting unit 35 around the rotating axis adjusting the horizontal angle of the telescope in the horizontal plane. In addition, a lens controller for focusing is installed in the distance measuring unit 31, and software for controlling these motors and controllers and for operating respective function buttons of the total station is prepared in the terminal computer device 20 so that the survey operator can use the vehicle. While watching the image sent by the object observation camera in the main body 52 through the monitor 25 of the terminal computer device, these motors are adjusted through the input means 26 to perform collimation and surveying.

At this time, a communication line and a power line for connection between the total station 30 of the vehicle trailer (loading box 54) and the terminal computer device 20 of the vehicle body 52 connect the vehicle body 52 and the vehicle trailer 54. It may be installed in parallel with the mechanical connection to connect, but the communication is made by Bluetooth, which is a kind of short-range wireless communication, and the power is separately installed in the total station itself has the advantage that the connection is not complicated.

When operating such a vehicle-mounted total station, the measurement operator does not need to move to the seat where the total station 30 is installed to check the object, thus simplifying work, saving time, and surveying when the surveyor performs the survey. Since the vibration of the total station 30 due to the movement of the ruler can be prevented, it is possible to increase the accuracy of the survey.

Meanwhile, in the system of the present invention, a fixed prism may be installed in a target 60 that constitutes an important feature on a map as a surveying target of the total station. Prism is a device that uses a special reflector called a corner cube, which reflects the incident light three times and returns it to the direction of incidence exactly. If the reflective surface is precisely formed, the reflection can be made with a minimum loss of light intensity and can be surveyed at a distance of several km. In order to precisely collimate this target, the autofocus module can be equipped with a total focusing device that aims precisely at the center of the prism by roughly aiming near the prism, and this function can be used when surveying using a prism target method. Can only be applied. This autofocus module can be applied to the existing auto tracking technology that can collimate while tracking a moving target.

Although it is not an accurate target method, if the number of targets is large and the object is relatively close to within several hundred meters, a reflector may be installed rather than a prism so that the laser pulses generated by the total stationary light emitter may reflect the reflector. have. Telephone poles and street lamps around the road may be equipped with recording plates or parts with a well polished surface similar to reflecting plates. Surveying may be performed using such recording plates or parts as reflecting plates.

If the reflector or prism is installed outdoors, foreign matter such as organic matter or dust may be placed on the surface and interfere with the measurement. In this case, the Pikington has surface self-cleaning ability to reduce the trouble and cost of periodically removing the foreign matter. The use of titanium oxide coatings, such as the Pilington Active glass, allows the surface foreign matter to detach from the surface itself through the catalysis of light and the cleaning of rainwater so that the surface is always suitable for reflection. The prism or metal plate to be installed at the designated position should be mounted at the position where the on-vehicle total station can be easily collimated, and the installation should be at an easy angle to collimate at the expected total station position.

On the other hand, in the system of the present invention, the vehicle-mounted total station does not always measure only the designated features, and some of them accurately measure new features that were not previously present or existing features, but precisely when predicting changes in the surroundings. In order to make an accurate measurement, it is necessary to measure additionally. In this case, the installation of a prism on an object requires a lot of manpower, effort, and time as in a conventional survey, and it becomes difficult to carry out surveying by a surveyor alone.

Therefore, as a total station of the present invention system, a non-target method is also available. In the non-target method, the reflected light is scattered from the surface and the sensitivity is very low. However, at a close distance, the reflected light can be detected even without the reflecting plate. Therefore, at this distance, the total station can be surveyed using a non-reflective plate and a prism-free state. The prism mode and the non-prism mode of the total station can be used to select the reflected light sensitivity through separate selection buttons, and the selectivity can be selected by the surveyor in the vehicle using the terminal computer device.

The above description is for using the mechanical point for the total station by using the GPS receiver.However, when the survey reference point is measured at a relatively close distance or when the measurement needs to be measured with high precision, the survey point is measured during the survey process. It is possible to calculate the position coordinates of the survey target by calculating or inverting the points measured before and after the reference.

This requires the precision of the centripetal operation in which the total station body is at the same coordinate as the survey reference point at the survey reference point.

However, working with the total station down from the vehicle for the centripetal work requires a lot of manpower and time and is complicated like the existing total station surveying work. Work also needs to be done precisely.

To this end, this embodiment uses a total station equipment equipped with an automatic centrifugal module including a laser centrifuge, and installs a window at the top of the trailer below the total station body to check the surveying reference point of the ground.

To ensure that the total station body is directly above the survey reference point, move the vehicle itself or the total station loading box when the error is large so that the body of the total station matches the coordinates with the survey reference point. It can be installed and linked with a mechanical device such as a coordinate table to move the position to the correct coordinates.

As a method of moving the coordinates, remote control and automatic control may be used. Remote control means that the user of the vehicle moves the moving motor of the coordinate adjustment table directly using the terminal computer device while looking at the camera installed with the centrifugal device. The automatic control is performed in a certain area through the image processing program installed in the total station. In order to match the body coordinates with the survey reference point, the body moves in the coordinate table in conjunction with the camera and the motor of the coordinate table.

The coordinate adjustment table may include, for example, a pedestal for fixing the main body, an x-axis rail for movably fixing the pedestal, an orbital rack coupled with the pedestal to move the pedestal on the x-axis rail, a pinion and pinion coupled with the pedestal. X-axis moving motor to drive, y-axis rail to fix x-axis rail to y-axis movable, tracked rack combined with x-axis rail to move x-axis rail on y-axis rail, pinion and pinion combined with rack It may be provided with a y-axis moving motor for driving the.

With the system of the present invention, a database of numerical information obtained by aerial photographing or other methods of creating a numerical map is provided in the central computer of the information center, and the region is corrected when the map correction reflects the recent feature changes. A vehicle equipped with a total station, a GPS receiver, and a terminal computer device can be used to move the vehicle movably and to use 3D location information of many survey points directly from the central computer using the simplicity of installation and surveying. The central computer can receive this survey data in several routes and update the numerical database or modify the map quickly and easily by reflecting the difference from the previous location data.

In addition, for important features, a systematic method of surveying a large number of surrounding points by using a reflector or prism in advance so as to be a basis for determining the change of the terrain and when there is a large error out of a certain range of the measurement value can be used. Therefore, it is possible to efficiently collect location information and maps that reflect changes quickly, especially in areas where feature changes and map changes are large.

For example, the information center also receives three-dimensional position information of the prism installation point received from each vehicle in close proximity to the real time through the network, and stores it in the collection information database. Compared with the location information and there is a big difference out of a certain range, it is judged and sent back to the vehicle's surveyor through the network again to know the singularity and to survey the surroundings more intensively and efficiently to change the feature changes on the central computer data. It is possible to update the accurate numerical map by reflecting.

In the present specification, the present invention will be described based on the embodiments and drawings described, but the configurations described and illustrated herein are only one embodiment of the present invention, and do not represent all of the technical ideas of the present invention. It should be understood that there may be a variety of equivalents and variations that could replace them at the time of filing.
