Description

A method of adjusting temperature of carrier in an aerial photography plotting instrument

The present invention relates to a drawing method using an apparatus for reading an aerial photo used to obtain geographic information, and more particularly, to a method of controlling the temperature of an aerial photo carrier in an aerial photogram apparatus used for drawing. will be.

The flasher refers to equipment for producing topographic maps using quantum film from aerial photographs. The projectors can be broadly classified into analog processors, analytical ones, and numerical ones.

The projector is basically composed of a stereo comparator and a coordinatograph. Servomotors and encoders are an important part of the components of the projector, and they are devices that control the automatic measurement of photographic tasks.

The lighter can calculate the mathematical model using the collinear conditional equation. The external inputs needed to solve the equation are the internal coordinates of the camera and the ground coordinates of the reference point, and the internal inputs are the coordinates measured by the projector itself.

From this data, the computer can calculate model coordinates and other useful results in real time. The projector sends the measured data to a coordinatograph for display on the screen or for printing or printing in hard copy form.

In addition, various drawing methods using aerial photographs include a correction drawing method, an analysis drawing method, and a numerical drawing method.

Modified drawing method is a representative method of mechanical photogrammetry. It is a method of drawing a digital map by performing partial drawing on the area changed through aerial photographs and Dohwawon map, digitizing and merging it with existing digital map.

In other words, it is easy to confirm the correction factor through comparison with the aerial photo, and it is possible to directly produce the correction file for the updated contents. In the case of updating the digital map by photogrammetry, it is possible to convert large numbers of aerial photographs into the ground coordinate system at the same time.

Unlike the analytical drawing method, the numerical drawing method is a drawing operation using an image file. When updating the digital map by the numerical mapping method, an imaging process of aerial photographs is required. This can be achieved by photographing the first aerial photograph with a digital camera or by scanning the aerial photographic film with a high resolution scanner. The numerical mapping method may perform processes such as image registration, aerial triangulation, and digital terrain model (DTM) generation in finely divided unit pixels.

In general, when a drawing operation is performed, a pair of aerial photographs (left eye and right eye) of the area are first photographed. The operator can perform the drawing operation by displaying different portions on the digital map while checking numerical maps corresponding to the three-dimensional (three-dimensional image) aerial photographs and aerial photographs through stereoscopic glasses (polarizing screen and polarizing glasses).

However, in the case of using the fuser, when a temperature difference occurs in the inside of the fuser as the drawing operation is performed, or when the temperature of the space where the fuser is installed is too high or low, the airborne positive film may have a play or expansion. In other words, external deformations that occur in the aerial photo film may hamper the drawing performance. The drawing performance caused by the deformation of the aerial photography film may be at least 5000 times more error than normal.

If the saved drawing cannot be restarted, the aerial picture can be re-started from the beginning by using the aerial picture injector.

1 is a view showing a logical block diagram of an aerial photogram equipped with a thermostat system used in the present invention, as an embodiment of the present invention.

Referring to FIG. 1, an aerial photographic projector having a thermostat system may include an input unit 100, a thermostat system 120, a controller 160, and an image display unit 180.

The input unit 100 may be an apparatus for receiving an aerial photographic film, and may include a carrier. Of course, in addition to the aerial photographic film, various geographic numerical information and user information may be input.

 The thermostat system 120 is a system that maintains a constant temperature of the aerial photo fuser. In particular, in an aerial photographic fuser, the temperature of the aerial photograph carrier on which the aerial photograph positive film is placed needs to be constant.

An aerial photoshoot constitutes one aerial photo model. For example, aerial photographs are shot two by one overlapping a certain portion of a specific area. The aerial photo carrier is the part that holds the aerial photo taken of a specific area for drawing purposes. Therefore, the aerial photo carrier may be configured with a pair of aerial photo carriers on the left and right sides to receive a single aerial photo model and perform drawing.

During the drawing operation, a temperature difference inside the aerial photographic fuser may occur. For example, the temperature of the whole aerial photograph carrier may become higher than the predetermined temperature K, or the temperature difference of the carrier of the left and right sides of an aerial photograph carrier may arise.

In this case, since the temperature of the aerial photogram may be transferred to the aerial photogram positive film, slight play or stretching may occur in the aerial photogram film. This directly affects the drawing work. At least 5,000-fold errors may occur in the drawing performance caused by deformation, such as play or stretching, of an aerial film.

Therefore, it is a very important factor in the aerial photogramming operation that the temperature of the aerial photogram, in particular the aerial photo carrier, is kept constant. In FIG. 1, the thermostat system 120 may perform a function of maintaining a constant temperature of an aerial photogram and an aerial photo carrier at all times.

In FIG. 1, the controller 160 controls the input unit 100, the automatic temperature control system 120, and the image display unit 180. The controller 160 generates an aerial photograph model from a pair of aerial photographic positive film input to the thermostat system and input unit for maintaining a constant temperature of the aerial photograph carrier, and surveys a specific region using the aerial photograph model. An aerial survey system and a stereoscopic image processing system for processing the geographic information surveyed from the aerial survey system to a stereoscopic image. The controller may display the stereoscopic image output from the stereoscopic image processing system to the user through the image display unit 180.

In FIG. 1, since the gist of the present invention may be obscured, the aerial survey survey system and the stereoscopic image processing system are not illustrated in detail. However, if necessary, the aerial surveying system and the stereoscopic image processing system may use systems generally used in the art.

In addition, the controller 160 may control the temperature control system 120 to maintain a constant temperature of the aerial photographic fuser, thereby increasing the precision of the aerial photographing operation.

2 is a block diagram illustrating a configuration of an aerial photograph carrier and a thermostat system according to another embodiment of the present invention.

Referring to FIG. 2, the thermostat system is connected to one side of the aerial photo carrier 210 and may include a heat sensor 250 and a constant temperature holding unit 270. In embodiments of the present invention, the aerial photo carrier 210 may be composed of a pair of the left carrier and the right carrier to receive a pair of aerial photo positive film.

A thermostat system is a system that maintains a constant temperature of an aerial photovoltaic and / or a specific portion of an aerial photovoltaic. In particular, FIG. 2 will be described taking an example of maintaining a constant temperature of an aerial photo carrier included in an aerial photo fuser.

The heat sensor 250 may periodically check the temperature of a predetermined portion of the aerial photographic fuser or the aerial photograph carrier 210. In addition, the heat sensor 250 may feed back the heat information periodically inspected to the constant temperature maintaining part and / or the control part 160. The heat sensor 250 used in the embodiment of the present invention may use a general heat sensor used in the art.

The heat sensor 250 may measure the temperature of the aerial photo carrier 210. If the temperature of the aerial photo carrier 210 is out of a predetermined level, for example, 20 to 25 ° C., the constant temperature maintaining unit 270 and the controller 160 adjust the temperature of the aerial photo carrier 210 to fall within the range. Can be. The temperature range of the carrier can be arbitrarily set by the user.

For example, the controller 160 and / or the constant temperature maintaining unit may receive the thermal information from the heat sensor 250 and confirm that the temperature of the aerial photograph carrier 210 is greater than or equal to a predetermined temperature K. Therefore, the control unit 160 may stop the drawing operation and control the constant temperature maintaining unit 270 to lower the temperature of the aerial photograph carrier 210 below a predetermined temperature (K).

The temperature maintaining part 270 may include a cooler to lower the temperature of the aerial photographic carrier below a predetermined temperature (K). For example, the constant temperature maintaining unit 270 may apply the external wind to the aerial photo carrier to maintain a constant temperature of the incubated photo carrier.

In addition, the constant temperature holding unit 270 may include a heater for continuously applying a constant heat to the aerial photo carrier, the constant temperature holding unit 270 the temperature of the aerial photo carrier reaches a predetermined temperature In this case, application of the constant heat to the aerial photo carrier can be stopped.

In addition, the constant temperature maintaining unit 270 may maintain a constant temperature of the left carrier and the right carrier of the aerial photograph carrier 210. For example, the heat sensor 250 may periodically measure the temperature of the left carrier and the right carrier of the aerial photograph carrier 210 and feed it back to the constant temperature maintaining unit 270 and / or the controller 160. At this time, the carrier temperature of the left and right sides may be different during the drawing operation.

If the left and right aerial photograph carriers have different temperatures, the heat applied to the aerial photograph positive film differs even if the temperature is lower than the predetermined temperature K, so that the play or the stretching of the left and right aerial photograph positive film may occur. Therefore, when the temperature of the left and right aerial photographic carriers is different, the constant temperature holding part can constantly adjust the temperatures of both carriers by applying constant heat to the left and / or right aerial photographic carriers.

For example, when the temperature of the left carrier is greater than or equal to a predetermined temperature K, the constant temperature maintaining part may lower the temperature of the left carrier by using a cooler and apply a little heat to the right carrier to keep the temperature of the left and right carriers constant. Further, even if the temperature of the left and right carriers is lower than the predetermined temperature K, when the temperature of one carrier is higher than the other, separation may occur in the left and right aerial photographs, so that the constant temperature holding part has a predetermined heat in the other carrier having a low temperature. It can be applied to keep the temperature of the left and right carriers constant.

3 is a view showing an example of a drawing method using an aerial photoshooter equipped with a thermostat system as another embodiment of the present invention.

The drawing method reflecting the technical idea of the present invention and the method for adjusting the temperature of the aerial photo carrier in the aerial photogram may proceed simultaneously in parallel with each other. That is, while the aerial photographing method is in progress, the automatic temperature control method of the carrier included in the aerial photographing fuser may be performed in real time.

First, the drawing operation is explained first in FIG. Referring to FIG. 3, the user may start the drawing operation (S300).

The user may acquire a pair of aerial photographs in which a predetermined region region is captured in a specific region. At this time, the raw data used for the analysis photogrammetry is a pair of aerial photographs. That is, it may be various types of negative or transparent positive. Basic input data are photographic coordinates obtained in planar Cartesian coordinates, and output data are facial expressions such as ground coordinates.

When the user receives a pair of aerial photographs, the user can select a reference point and perform a survey operation on the aerial photograph. The user may also perform facial or aerial triangulation.

Expression work performed at this time includes internal expression, mutual expression, and absolute expression.

Interior Orientation is achieved by setting the relationship between the image coordinates scanned by the projector and the picture coordinates based on the principal point. Internal distortion can be used to correct distortion of a picture by using information such as image coordinates of four fiducial marks and information about a pub and a lens of an image, which are camera information.

While the internal expression aims at reproducing the optical environment inside the camera, the external orientation aims to define the positional relationship between the camera and the object. The external expression is composed of relative orientation and absolute orientation according to its purpose.

Cross-expression may be performed after internal presentation is performed. In addition, the mutual expression is performed as a part of removing the longitudinal disparity to the conjugate point while acquiring the coordinates of the three-dimensional model.

A pair of photographs with all disparities eliminated through mutual expression can form a complete stereoscopic model. However, this three-dimensional model defines the relative relationship between the two photographs while the left photograph is fixed. Therefore, the three-dimensional model does not have a proper scale and horizontality and does not form an exact similar relationship with the actual terrain. Therefore, in order to fit the three-dimensional model with the actual terrain, a coordinate transformation process for converting a model coordinate, which is a three-dimensional virtual coordinate, into an object space coordinate system is required. This process is called absolute orientation.

Alternatively, aerial triangulation may be used instead of such facial expressions. Aerial triangulation is the most important part of the analysis photogrammetry. In aerial triangulation, the coordinates of a myriad of points on the reaper are observed by a stereographic device and a precision coordinate observer, and then the absolute or geodetic coordinates of a number of points observed using a small number of reference points (or ground reference points) are measured by an electronic calculator. It can be converted into coordinates.

The user may acquire ground coordinates and facial expressions through surveying. Thus, the user can partially figure out the correction elements, combine with existing data or update existing data through surveying. At this time, the existing numerical map can be edited in the exact location file, and can be updated or reflected in the numerical map as well as the local survey data. The generated numerical values can be used to create and edit drawings.

While performing the drawing process, as another embodiment of the present invention, an aerial drawing method using an automatic temperature control system capable of maintaining a constant temperature of the aerial photographic burner may be applied.

As the drawing is started (S300), the thermostat system can periodically or continuously measure the temperature of the aerial photography and / or aerial photography carrier. In this case, it is assumed that the thermostat system uses the thermostat system described with reference to FIG. 2 (S310).

The controller and / or the thermostat may inspect the temperature information received from the heat sensor. At this time, the control unit and / or the temperature maintaining unit may check whether the temperature of the feedback aerial photo carrier corresponds to a predetermined temperature (K), for example, 20 ~ 25 ℃ (S320).

If, in step S320 the temperature of the aerial photo carrier is out of a predetermined temperature (K), the control unit and / or the temperature maintaining unit may stop the drawing operation (S330).

In operation S330, the control unit and / or the temperature maintaining unit may store the drawing file in a state where the work was last performed when stopping the drawing work in the database.

The control unit may adjust the temperature of the aerial photo carrier using the thermostat system (S340). Adjusting the temperature of the aerial photo carrier is to lower the temperature of the aerial photo carrier by using a cooler (cooler) included in the constant temperature holding unit of the thermostat system, or a heater (heater) included in the constant temperature holding unit It is possible to increase the temperature of the aerial photo carrier using. For example, when the temperature of the aerial photo carrier becomes more than a predetermined temperature K, the constant temperature holding unit may lower the temperature of the aerial photo carrier using a cooler. In addition, as another embodiment of the present invention, the aerial photo carrier may be composed of a pair of carriers (see FIG. 2). In this case, when a temperature difference occurs in the left and right carriers, the temperature may be reduced by using a cooler only on a carrier having a predetermined temperature K or more. In addition, when a difference occurs in the temperature of the left and right carriers even if the temperature is less than the predetermined temperature K, a predetermined temperature may be applied only to a specific carrier in order to make the temperature of the left and right carriers the same. That is, the temperature of the left carrier and the right carrier can be adjusted independently of each other.

When the internal temperature of the aerial photograph carrier or aerial photograph fuser is adjusted to 20-25 ° C., the controller may resume the drawing operation (S350).

When the drawing operation is resumed, the drawing may be performed again using the drawing file stored in step S330, or the drawing operation may be performed again from the beginning for a more accurate drawing operation.

When the temperature of the carrier corresponds to a predetermined set temperature, for example, 20 to 25 ° C. in step S320, the controller of the fuser may continuously perform the drawing operation by maintaining the drawing operation (S360).

The aerial photography incubator having a thermostatic system according to the invention may further comprise a lamp for low heat emission, in order to keep the temperature of the carrier constant. In order to image a positive film mounted on a carrier through a prism, a lamp for generating light is required. The lamp is positioned above the carrier, and typically a halogen lamp of 8 to 10 W is used, in which heat generated with light is transferred to the carrier, thereby causing the expansion of the positive film mounted on the carrier. The low heat emitting lamp is characterized in that the illuminance (Illuminance) is the same as a conventional lamp and emits low temperature heat.

In addition, the aerial photography of the thermostat system according to the present invention may further include a screen membrane for blocking heat, but allowing light to pass between the low heat emission lamp and the carrier in order to maintain a constant temperature of the carrier. Can be.
