Abstract

An on-the-spot investigation system for recording a photo image is provided to conveniently, correctly, and quickly construct a spot photo database for storing the photo image of a building and a road with small manpower by using a PDA(Personal Digital Assistant). A conversion program(12) is installed in a computer(10) for storing photo images, and converts computer data into a PDA data format and vice versa. A PDA(20) includes a photographing function, a GPS(Global Positioning System) reception function, and an input program for collecting/storing photo data, coordinate data, and direction data, and exchanges the data with the computer through the conversion program. A digital compass(30) is embedded in the PDA or is fixed to the outside of the PDA by using a fixing tool, and is connected to an internal circuit of the PDA. The input program stores the photo image, stores the coordinate data received from a GPS, and stores the direction data received from the digital compass at the same time when the photo image is captured by using a camera, and stores necessary information such as a photographing time and a photographer name by linking with the photo image and the coordinate/direction data.

The present invention relates to a field surveying system for photographing buildings or roads in the field in order to build an effective field photographing database, and efficiently inputting and storing them in a computer to perform input or modification of a database.

The field where the photographic image of the site is organized into data is very diverse in the current information society. For example, when a land or housing related work or complaint occurs in a government office, a public official in charge of the field goes to the scene and takes a picture as evidence. There may be a task that allows you to see the stored image to handle the work or complaints, and when the police need the image of the site to resolve the case / accident, private companies or land and housing appraisals related to guidance And the like.

If you look at the process of proceeding such a task in the past, the person in charge of the field survey work to build a database to print out the map and carry it directly, visit the site and fill out the information collected from the site in the drawings, photographs This is to confirm the location where information is needed through a map and then take a picture. By hand, we recorded the location where the picture was taken on the map, when and from which direction and in which direction, and other references. If you send it to the person in charge of organizing and inputting it, the person in charge of the final person checks the received data and inputs or revises it.

According to such a conventional working method, very inconsistent and inaccurate data and information are very likely to be input, and a considerable amount of effort and effort are required to perform inefficient work.

In other words, according to the conventional work described above, it is difficult to accurately display the information collected through the field survey, and it is difficult to accurately display it because it is necessary for a person to judge and record the position and direction of taking a picture. It requires a lot of effort and manpower, but also has a lot of errors. Therefore, there is a limit to inputting uniform and accurate data.

In addition, since the information is recorded by hand, necessary information may be missing, and the final worker may not be able to judge the information recorded by hand, and may request confirmation again, or input the information recorded by mistake. There were many problems during the field survey.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and an object thereof is to enable accurate and convenient data formation of field photograph images using a PDA, and to perform such a task very quickly and with little manpower.

The present invention is to use the PDA with a camera and GPS function to proceed with the operation, and also to convert the data of the computer (PC) to input or to convert the data of the PDA to be input to the computer and PDA By using a digital compass, etc. can be connected to the use of the image capture and information acquisition and information is very convenient and accurate bar according to the preferred embodiment of the present invention according to the accompanying drawings As follows.

1 is a conceptual diagram showing a state of exchanging data with a computer according to the present invention, Figure 2 is a functional diagram of a PDA according to the present invention.

In order to implement the present invention, first, a conversion program 12 must be constructed in a computer 10 in which a photographic image is stored. A condition required for the conversion program 12 is a PDA in the storage device 11 of the computer 10. Since the map must be transmitted to the storage device 21 of 20, a function of converting computer data to a PDA is required, and of course, a function of converting PDA data to a computer is also required.

The conversion program 12 is built in the computer 10 to receive the map data from the computer using the PDA as a basic data for photographing during field survey in the PDA 20 and after the storage device 21 of the PDA 20 The computer 10 receives the data stored in the final cleanup and storage.

An important component of the present invention is to include a PDA 10 having a photographing function and a GPS receiving function. At the same time, a digital compass 30 must be coupled to the PDA.

Digital compass 30 is built in the PDA (20) is connected to the internal circuit, or having a means for permanently or temporarily fixed to the outside to be integrated and connected to receive data, PDA ( 20) while taking a picture using the angle (orientation) to take a picture accurately measured while at the same time so that the measured orientation is immediately delivered to the PDA (20).

In addition, the PDA 20 has to build a data input program 22 having a function of collecting and arranging various data together with the photographed picture. Looking at the function of the data input program 22 as follows.

When taking a picture using the camera 23, at the same time to save the picture image and receive the position coordinates from the GPS, and at the same time receive the recording direction of the picture taken from the digital compass 30 and at the same time to save the other shooting time, photographer Information such as name is automatically stored to be linked with the photographed image and direction data.

In addition, it is configured to manually input the position coordinates and direction in case the area where GPS or digital compass can not be received.

In addition, it is also possible to input notes to be input as voice data using the voice recording function of the PDA.

In the drawings, reference numeral 15 denotes a monitor, 16 keyboard, and 24 manual input device.

Looking at the operation of the present invention according to the method of use as follows.

First, map data stored in the storage device 11 of the computer 10 is downloaded to the PDA 20 using the conversion program 12.

The worker carries the PDA 20 and moves to the site where the picture is to be taken.

The PDA 20 is operated and the map image is opened to confirm the place to be photographed, and the picture is taken using the camera 21.

At the same time as taking a picture, the data input program 22 automatically records the remaining information at the same time and combines them into a linked file, including position coordinates received from the GPS, direction data by the digital compass 30, and other shooting times. Information about the photographer, photographer, etc. is automatically entered and saved as a linked file.

After the shooting is finished, return to the working position to transfer the shooting information stored in the PDA (20) to the computer 10 and to convert the file to be used in the computer 10 by using the conversion program (12).

Accordingly, when the photographing point displayed on the map data is selected in the computer 10, the stored photo image is opened, and the remaining information such as the position, direction, and time combined with the photo image is displayed.

In addition, according to the present invention, since it uses a medium called PDA, it also has the advantage of being able to transmit using wireless communication in real time.

According to the present invention as described above, even beginners can easily and accurately secure the photographic image of the site, and because the time is very short, it will be referred to as a system that can achieve the maximum effect even with a small number of personnel. In order to go and take a picture, there is no problem of outputting a map of the site, which is convenient and can reduce costs.

In addition, there is an advantage that the work is naturally and quickly connected between the operator who acquires the photographic image in the field and the operator who inputs the data through the captured image, and there is no fear of input error or omission and always obtains uniform and accurate data. It is a very useful invention that can achieve excellent effects in many ways.
