Description

[0001] The present invention relates to a time-lapse video production apparatus and a method thereof,

The present invention relates to a time-lapse video production apparatus and method thereof, and more particularly, to a time-lapse video production apparatus and method for capturing a still image of a construction process of a large structure having a plurality of photographing positions using a radio- The present invention relates to a time-lapse video production apparatus and method for producing a laps video.

Time-lapse (Time-lapse) is one of the techniques of photography. It is a special image technique that continuously reproduces images taken at fixed intervals for a long time at a fixed interval for a short time. In order to produce such a time-lapse image, a high-specification computer equipped with a moving image editing program for editing a still image that requires an expensive camera is needed.

In the past, in order to photograph a building or produce a three-dimensional building model of a photo mapping, a method of producing a three-dimensional virtual reality digital map by capturing images on the ground and mapping the photographs to buildings is used. This method has the advantage of obtaining high quality image information and spatial information of high resolution, but it is difficult to obtain visibility due to the obstacles on the ground, and it is troublesome to take photographs by climbing up surrounding buildings to photograph each side of the building from the front Lt; / RTI >

In addition, it is difficult to freely set the photographing position or to move the photographing position even when the time-lapse image of the construction process of a large structure such as a building is produced. Conventionally, a camera is fixedly installed in a neighboring building or a separate structure is installed to fix a camera, and a time - lapse image is produced by reproducing an image photographed for a long time in a short time.

However, due to cost and field access problems, this method is not able to produce time - lapse images in various directions because one time location is selected and a time - lapse image is produced at a distance. Therefore, in order to capture the construction process of a large structure in various directions, the number of cameras corresponding to the position to be photographed must be fixedly installed to produce a time-lapse image.

This method is costly and requires a cumbersome process of removing the installed camera and reinstalling the camera in a new position when the shooting position is changed.

Hereinafter, a time-lapse video production apparatus and method according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram illustrating a schematic configuration of a time-lapse video production apparatus according to an embodiment of the present invention. And FIG. 3 is a view for explaining an image correction method of a time-lapse video production apparatus according to an embodiment of the present invention.

As illustrated in FIG. 1, a radio-controlled helicopter that can be moved in the air can be used as the time-lapse video production apparatus 100 of the present invention. The time-lapse video production apparatus 100 generates an image for producing a time-lapse video by photographing an object to be shot at a set position while flying around the object to be shot.

2, the time-lapse image production apparatus 100 includes a storage unit 110, a GPS reception unit 120, a distance sensor reception unit 130, a flight driving unit 140, a camera unit 150, 160, and a control unit 170.

The storage unit 110 stores a plurality of photographing positions P1, P2, and P3 to photograph an object to be photographed. Here, the photographing position stored in the storage unit 110 includes coordinates, a distance value and an altitude with respect to each distance sensor transmitter S, and the coordinates are composed of latitude and longitude coordinates by GPS satellites. The distance is a distance between the distance sensor S and the photographing position, and the altitude is the height H from the ground to each photographing position. Here, the photographing position stored in the storage unit 110 is included in an area where the distance sensor receiving unit 130, which will be described later, can sense a plurality of distance sensor transmitters S attached to the photographing object. The storage unit 110 further stores shooting periods for performing shooting operations at a plurality of shooting positions.

The Global Positioning System (GPS) receiver 120 communicates with the satellite to determine the current position. The current position, which is grasped by the GPS receiver 120, is compared with the actual position, and the error is corrected by the distance sensor receiver 130 described later.

The distance sensor receiving unit 130 senses the distance to the object to be imaged using a plurality of distance sensor transmitters S attached to the object to be imaged. An error between the current position and the photographing position detected through the GPS receiving unit 120 is corrected using the distance values sensed by the distance sensor receiving unit 130. [ This will be described in more detail below.

The flight driving unit 140 drives the air moving means for moving to a plurality of photographing positions. That is, the flight driving unit 140 drives the propeller or the like so that the time-lapse image producing apparatus 100 is moved to each photographing position. In addition, the flight driver 140 is controlled by a control unit 170 to be described later so that an error occurring between the current position and the photographing position detected through the GPS receiver 120 is corrected.

The camera unit 150 photographs an object to be photographed as soon as the photographing position coincides with the current position. That is, the control unit 170 controls the instantaneous photographing operation to be performed when the current position detected through the GPS receiving unit 120 coincides with the photographing position stored in the storage unit 110.

The image correcting unit 160 compares the outline of the object to be imaged included in the plurality of images sequentially captured by the camera unit 150 and corrects the imaging position error between the plurality of images. 3, the image correcting unit 160 compares the outline of the object to be imaged included in the second image I-2 with the first image I-1 to determine that the error E has occurred And corrects the second image I-2 by an error E generated and outputs the corrected second image I-2.

The control unit 170 controls the camera unit 150 to perform an instant photographing operation in which the current position recognized through the GPS receiving unit 120 coincides with the photographing position stored in the storage unit 110. [ At this time, the controller 170 controls the flight driver 140 so that an error between the current position and the photographing position, which are detected through the GPS receiver 120, is corrected using the distance values sensed through the distance sensor receiver 130. [

Generally, an error is generated when comparing the current position detected through the GPS receiver 120 with the actual position, and the error generated at this time is corrected using the distance values detected through the distance sensor receiver 130. [

Since the distance value between the photographing position P1 and each distance sensor transmitter S is stored in the storage unit 110, the current position sensed through the GPS receiving unit 120 is identified as P1 The position of the time lapse image producing apparatus 100 is corrected by controlling the flight driving unit 140 so that the detected distance value is equal to the stored distance value by detecting the distance between each distance sensor transmitter S at the photographing position P1, do.

The control unit 170 controls the flight driving unit 140 to be positioned at the same attitude as the photographing position stored in the storage unit 110 using the distance values sensed through the distance sensor receiving unit 130. [ That is, since altitudes at the photographing positions P1, P2, and P3 are stored, the flight driving unit 140 is controlled so that the time-lapse image producing apparatus 100 is located at the stored altitude.

The control unit 170 controls the flight driving unit 140 and the camera unit 150 to move to a plurality of photographing positions for each photographing period stored in the storage unit 110 and perform a photographing operation. That is, control is performed so that the photographing operation is performed in the order of the photographing positions P1 - > P2 - > P3 every set period. In other words, after the photographing operation is performed in the order of the photographing positions P1 -> P2 -> P3, the photographing operation is repeatedly performed in the order of the photographing positions P1 -> P2 -> P3 in the predetermined time.

4 is a flowchart illustrating an operation of a time-lapse video production apparatus according to an embodiment of the present invention.

Referring to FIG. 4, when the power of the time-lapse video production apparatus 100 is turned on (S200-Y), the time-lapse video production apparatus 100 jumps to the shooting position (S210). That is, the control unit 170 controls the flight driving unit 140 to move to the photographing position stored in the storage unit 110. The photographing position stored in the storage unit 110 includes coordinates, a distance value with respect to each distance sensor transmitter S, and an altitude. The photographing position is detected by a distance sensor receiving unit 130, And is included in an area where the transmitter S can be detected.

When the distance sensor transmitter S is sensed (S220-Y), the controller controls the flight driver 140 to correct the current position and the altitude detected through the GPS receiver 120 using the sensed distance values (S230) . That is, since the photographing position exists in the area where the distance sensor receiving unit 130 can sense the plurality of distance sensor transmitters S, when the time-lapse image producing apparatus 100 is made to fly to the photographing position, The distance sensor transmitter S is detected. At this time, the controller 170 controls the flight driver 140 so that the current position and the altitude at which the time-lapse image producing apparatus 100 is located are corrected using the distance values detected through the distance sensor receiving unit 130. [

When the photographing positions match (S240-Y), the photographing object is photographed at the photographing position (S250). That is, the control unit 170 controls the camera unit 150 to perform a photographing operation at a moment when the photographing position stored in the storage unit 110 matches the current position of the time-lapse image producing apparatus 100. In other words, the coordinates of the time-lapse video production apparatus 100, the distance to the distance sensor transmitter S, and the altitude correspond to the coordinates stored in the storage unit 110, the distance to each distance sensor transmitter S, An object to be photographed is photographed through the camera unit 150. [

Finally, the imaging position error between the plurality of photographed images is corrected (S260), and the imaging process of steps S210 to S260 is repeated according to whether or not the imaging period is set (S270-Y). That is, when a plurality of images are captured, the outline of the object to be captured included in each image is compared to correct an image by an error generated when an error occurs. The photographing is repeated or terminated according to the set photographing cycle.

With the above process, the time-lapse image can be produced by photographing the object to be photographed at a plurality of photographing positions using one time-lapse image producing apparatus 100.

In the present invention, the image correction unit 160 is included as a component of the time-lapse image production apparatus 100. However, when the image correction unit 160 is provided in an external computer (not shown) It is possible to wirelessly transmit an image photographed by the image producing apparatus 100 to an external computer to perform image correction, and to produce a time-lapse image.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined in the appended claims. It can be understood that it is possible.
