Detailed Description of the Invention

[0001]

The present invention relates to verification of construction of various buildings during or after construction, on-site verification of construction status and maintenance status of roads, railways and rivers, and record of accident scenes and crackdowns on parking violations. The present invention relates to a handy computer equipped with a digital camera that can be easily used when performing such operations, and a method for recording a field situation using this device.

[0002]

2. Description of the Related Art For example, in new construction or reconstruction work of various buildings, a verification record of the state during construction or after construction (hereinafter,
There are many situations in which this is called field verification). Conventionally, this on-site verification record was taken by both the main contractor and the subcontractor by bringing the architectural design drawing and camera to the site, and the original contractor confirmed whether the building was constructed according to the design drawing When the location is found, the main contractor points it out to the subcontractor, the subcontractor checks the pointed point on the drawing, takes a picture of the pointed out point, and points out this picture and the pointed out point on the drawing. And are associated and recorded in writing.

[0003]

However, it is not only complicated to associate the defective point on the drawing with the photograph, but it is not easy to write on the design drawing and operate the camera at a construction site where the scaffolding is poor. There wasn't.

Further, the materials produced by such verification results need to be stored for a certain period of time, but since this storage is stored in the form of documents, it will be possible to save a huge amount of verification materials at a later date. , It takes a lot of time to retrieve the relevant materials. It is also possible to convert the stored materials into electronic files for the purpose of rationalizing the management of materials, but in this case,
Since it is necessary to read the design drawings and photographic images with an image scanner etc., there is no change in that it takes time and effort.

Such various problems are not limited to the on-site verification of the construction status of a building, but are common to other works requiring on-site verification. For example, in the record of on-site verification of construction and maintenance status of roads, railways and rivers,
I bring a wide area map and a camera including the planned verification site to the site and take a picture of the verification site while checking the verification site on the map. However, even in such work, there are the same problems as above. In addition, the same problem is caused when maintenance and inspection of buildings based on architectural drawings, road maintenance based on road maps, river maintenance based on river maps, and track maintenance based on railroad track maps. In some cases, verification of civil engineering and road construction conditions is performed based on general maps and road maps, and cases of accident sites are verified based on the same maps.

The present invention has been made in view of the present situation, and it is indispensable to provide a design drawing, a map and a camera for recording the construction status of buildings and the construction status and maintenance status of roads, railways and rivers. The purpose is to provide a technology that can greatly simplify this kind of on-site verification work, and also facilitate the management of recorded materials.

The lens attached to the lens 22 or the opening 24 may be either a glass lens or a resin lens. A resin lens is preferable from the viewpoint of weight saving and cost reduction. The lens may be provided with a structure capable of moving back and forth to realize the focus function. Also,
It is also possible to reduce the number of parts by providing only one lens directly attached to the opening 24. In addition, CCD21
It is also possible to use a single imaging component in which the lens 22 and the lens 22 are integrated from the beginning. The position where the opening 24 is formed is not limited to that shown in the figure, and may be the upper surface or the back surface of the adapter case 23.

The CCD 21, the lens 22 and some element groups 26 are directly mounted on a single substrate 27.
The optical axis connecting D21 and the lens 22 is arranged so as to be located on the path of the light incident from the opening 24 of the adapter case. A multi-core flat cable 28 is led out from one side of the board 27, and the other end of the cable is connected to the male bus coupling terminal 25 (not shown). Since all the main parts of the optical system and the electrical system are mounted on the single board 27 in this way, the digital camera adapter 20 can be assembled very easily and the assembly cost can be reduced.

There is. By doing so, it is not necessary to separately provide an adapter-side bus coupling terminal and it is not necessary to use a multi-core flat cable, so that the number of assembling steps can be further reduced. In the illustrated example, the image pickup component 21a in which the CCD and the lens are integrated is used, but it goes without saying that the CCD and the lens may be separate components.

The GPS adapter 30 incorporates a GPS 31, which is a so-called global positioning system, which is an absolute position measuring device using a communication satellite. A male bus coupling terminal 33 and a female bus coupling terminal 34 are provided on the outer surface of the case 32 of the GPS adapter 30, and the male bus coupling terminal 33 can be attached to the bus coupling terminal 8 of the handy computer body 1, while The female bus coupling terminal 34 is configured so that the digital camera adapter 20 and the printer 40 can be mounted. GPS31
Can receive the position signal from the communication satellite and measure the current position of the observer within an error range of several meters. By sending this position data to the handy computer body 1, This makes it easy for the verifier to specify the current position on the drawing or map information. Therefore, when the handy computer handles map information, it is particularly preferable to equip the GPS adapter 30. When the handy computer handles information such as architectural design drawings and floor plans, the GPS adapter 30 is not necessary. In this case, the digital camera adapter 20 and the printer 40 are connected to the bus connecting terminal 8 of the handy computer body 1. It is installed.

Inside the handy computer having such a hardware configuration, each means for realizing the processing contents shown in FIG. 3 is constructed by software or hardware. Here, the case where the “floor plan of the condominium” is stored in the memory 4 of the handy computer will be described as an example, and the procedure for recording the site situation based on the floor plan will be described.
The drawing information stored therein may be a more complicated architectural design drawing, map information, or the like.

First, a storage means 11 is provided for storing the peripheral drawing information <a> including the verification scheduled site. Although it is preferable that the memory capacity of the storage means 11 is sufficient to store the floor plans for a plurality of houses at the same time, it is assumed here that the floor plan for one house is stored in the storage means 11. Proceed. The storage means 11 is usually composed of a part of the memory 4. The drawing information <a> may be vector data or image data.

Next, the drawing information <a> of the entire periphery stored in the storage means 11 (that is, the drawing information <a of the wide area <a>
>) Drawing information of narrow area including specific verification points <
There is provided a selection display means 12 for selectively calling a1> on the display device 6 and displaying it graphically. In order to extract the drawing information <a1> of the small area from the drawing information <a> of the entire surroundings, the drawing information <a> of the entire surroundings is first displayed on the display device 6, and the cursor movement key is displayed on this display screen. Operate 7b to move the cursor to a position near the verification point on the display screen and then press the area switching function key (not shown), or use the pen input device It may be considered to do so by directly indicating the nearby position. It is also considered that a pressure-sensitive touch panel capable of directly indicating coordinates on the display screen is laminated on the front surface of the display screen and the corresponding portion is pressed with a finger.

Further, there is provided a verification location specifying instruction means 13 for specifying on the display means the verification target location to be verified from the drawing information <a1> of the narrow area displayed graphically on the display device 6.

Further, there is provided a position data calculating means 15 for calculating the position data X, Y on the corresponding drawing at the location specified and designated on the display means in this way. This actual work is carried out by the microprocessor 3.

Further, an associated storage processing means 16 for storing the photographed image data <b> of the verification portion obtained by the image pickup unit and the position data X and Y in association with each other is provided, and the photographed image data <b> is stored. The position data X and Y are stored in association with each other. Live-action video data <b>
The position data X and Y may be stored together, but may be stored in separate memory areas and associated with each other. Since the position data X and Y correspond to the live-action image data <b> in this manner, it is always managed to which part of the drawing information <a> each real-image image data <b> corresponds to. For example, there is a damage on the "glass window on the balcony" and this "glass window on the balcony"
X and Y coordinates on the drawing information <a> of (1024, 61
In the case of 1), the position data (1024, 611) is added to the photographed image data of the damaged glass window and these are stored in the memory.

The handy computer is thus composed of a combination of hardware and software. Next, the overall construction of the on-site situation recording method using such a handy computer will be described for each step. The method of the present invention is constituted by <step A> to <step F> as shown in FIGS. Each process has the following contents.

<Step A> (FIG. 6) From the library of the drawing database 71 built in the computer 70 installed in the fixed base such as the office, the handy computer 60 receives the drawing information of the wide area including the verification site. hand over. As drawing information, architectural drawings such as design drawings and floor plans, general maps, topographic maps, river maps, maps for various purposes such as road maps, etc. are excluded, but drawings and maps other than these are excluded. is not. The computer 70 is connected to a communication network, and is configured to exchange information with, for example, a large-scale computer at the head office, computers at other business offices, and computers of other companies in the same business. Passing drawing information from the computer 70 to the handy computer 60
There are a method of performing it via a portable storage medium and a method of directly connecting the computer 70 and the handy computer 60 with a cable. IC as a portable storage medium
Cards, floppy disks, MOs, CD-ROMs, etc. can be used. From the viewpoint of easy handling, it is most preferable to use a non-contact coupling type IC card. CD-
If a ROM is used, writing on this medium is not possible, so the drawing database 71 itself of the computer 70 is stored on a large number of CDs without taking the form of data copying.
-ROM, and the corresponding CD from here
-ROM is selected and read by a CD-ROM drive attached to the handy computer 60. Since a CD-ROM can store a large amount of data, it can accommodate a large number of drawings at once, and since a CD-ROM containing general-purpose map data has already been developed, these are Can be used. However, in case of using CD-ROM, handy computer 60
The live-action image data and position data from the computer 70
It goes without saying that a rewritable medium such as an IC card or a floppy disk is required to restore the above.

In the following description, an example will be described in which the map information is used for the purpose of more concrete explanation, and the property information of the house for sale is created based on this map information.

<Process B> (FIG. 7) Bring the handy computer 60 in which the surrounding map information (wide area map information) including the verification site is stored to the verification site, and the specific verification location on the display screen. Narrow area map information including is selectively called. The narrow area map information is called by operating the cursor movement key 7b to move the cursor on the screen where the wide area map information is displayed and then pressing the enter key, or using the pen input device. Direct instructions. In addition, when the handy computer 60 is equipped with the GPS adapter 30, it is easier to call the narrow area map information. That is, the current position is automatically measured by receiving radio waves from a plurality of communication satellites only by activating the GPS after arriving at the site, and the corresponding coordinates in the wide area map information are calculated from the obtained absolute position. The narrow area map information including the verification site is automatically displayed on the display screen.

<Step C> (FIG. 8) In the narrow area map information displayed on the screen, a specific verification site is specified on the display means. Similar to the previous step B, the specific instruction is performed by operating the cursor movement key 7b, the pen input device, or the like. Then, the microprocessor calculates the position data X, Y corresponding to the specified point. When the accuracy of the GPS adapter is extremely high and the position can be measured within the error range of 2 to 3 m, the wide area map information is displayed and the manual operation for the specific instruction of the specific verification site on the narrow area map information is performed. Alternatively, all of these operations can be left to GPS.

<Step D> (FIG. 9) The attitude of the handy computer 60 is adjusted so that a specific verification location can be captured within the visual field of the image pickup unit.
Image the verification location. In the example shown in the figure, a single-family house is the imaging target, and an image of the house is displayed on the display screen. Since the image currently captured by the imaging unit can be monitored by the display device 6, a specific key on the keyboard 7 is operated to make an adjustment so as to obtain an optimum image. Then, after confirming that the image is in the optimum state, the enter key is pressed. It is not necessary to adjust the image every time, and if the shooting is performed in the same environment, it is sufficient to follow the adjustment state immediately before.

<Step E> (FIG. 10) The actual image data sent from the image pickup unit to the microprocessor via the bus and the position data X and Y are stored in association with each other. This manages which part of the map information the live-action image data of the house corresponds to.

<Step F> (FIG. 11) When the on-site imaging is completed, the handy computer main unit 1
The real image data and the position data, which are stored in association with each other in the storage means, are passed to the computer 70 installed in the fixed base. The same method as in the step A can be adopted for the data transfer from the handy computer 60 to the computer 70.

Through the above steps, information in which the live-action image data of the house and the position data on the map of the site of the house are integrated can be obtained. This is extremely useful as real estate information, because the location of the house becomes clear by the position data on the map, and the appearance of the house and the environment near the site become clear by the live-action image data of the house. This information can be used as it is or can be used by adding other related information.

As described above, the position data on the floor plan and the live-action image data of the damaged portion are associated with each other to inspect the construction state, and the position data on the map and the live-action image data of the house are associated with each other. Although the example of creating the property information has been described, the present invention can be widely applied to other fields. For example, maintenance of a building based on architectural drawings,
Perform road maintenance based on road maps, perform river maintenance based on river maps, perform track maintenance based on railway track maps, and verify civil engineering and road construction conditions based on general maps and road maps. It is also possible to use it to perform accidents and verify the accident site based on the map.
Also, as a somewhat unusual application, it can also be applied to parking violation enforcement records. When it is used to record the enforcement of parking violations, the number of the vehicle, the type of vehicle, the parking time and time, the parking location, etc. are input from the keyboard, and then the scene showing the parking state most accurately is imaged.
