The present invention relates to a control device of a pan tilt camera, and more particularly, to a control device of a pan tilt camera and a recording medium thereof.

In general, the following interface was used for the control of the pan tilt and zoom camera. That is, FIG. 1 is an example of a window screen for controlling a conventional pan tilt camera. As shown in FIG. 1, a pan tilt camera image 110 that reproduces an image captured by a camera in real time is displayed on one side of the window screen 100.

On the one side, an up key 121 and a down key 124 are provided to control the tilt operation of the camera, and a right key 123 and a left key 122 are provided to control the pan operation of the camera. . In the present invention, the tilt operation refers to an operation in which the camera rotates up and down, and the pan operation refers to an operation in which the camera rotates left and right.

On one side, a zoom out button 130 for zoom out control and a zoom in button 132 for zoom in control are provided. A speed adjusting scroll bar 140 is provided below the buttons 130 and 132 for controlling the speed of the pan operation and the tilt operation.

Such conventional pan tilt and zoom control of the camera is performed in the following manner. The camera can be rotated in a desired direction by clicking the keys 121, 122, 123, 124 using a mouse (or keyboard). At this time, if you click one step at a time, if you keep pressing, if you keep moving in the direction and release the mouse click the camera stops rotating.

In addition, the zoom-in or zoom-out of the camera was operated by pressing the zoom-in button 132 or the zoom-out button 130 once or continuously. And the pan tilt movement of the camera is to control the speed control scroll bar 140 frequently as needed because high speed is advantageous when moving large, and low speed is advantageous when moving finely.

However, the user interface of such a conventional pan tilt camera has the following inconvenience. That is, the combination of the pan operation and the tilt operation could not move in the diagonal direction. Therefore, it was forced to approach the desired diagonal direction by alternately operating the pan operation and the tilt operation. This has the disadvantage that it is very difficult to move to any position not visible in the pan tilt camera image 110.

In addition, there is an inconvenience that smooth and quick operation is difficult because the camera must be stopped without moving the camera every time the pan tilt speed is adjusted.

Accordingly, the present invention has been made to solve the above problems, the first object of the present invention, the control device of the pan tilt camera to provide a user interface more convenient to the user who wants to control the pan tilt camera to the desired position And a recording medium thereof.

Other objects, specific advantages and novel features of the invention will become more apparent from the following detailed description and the preferred embodiments described in conjunction with the accompanying drawings.

The invention will now be described in detail with reference to the accompanying drawings, in which preferred embodiments are shown. 2 is an example of a window screen for controlling a pan tilt camera according to an embodiment of the present invention. As shown in FIG. 2, a pan tilt camera image 210 is provided at one side of the control window 200 to display an image captured by the pan tilt camera 300 in real time.

On the right side, a first area 220 for detecting a click and a drag of a mouse (not shown) is provided. The first region 220 is shown in a circle. Inside the first region 220, a pan tilt handle 230 displayed to move like a dragged mouse is provided. Accordingly, when the user drags within the first area 220 while clicking the pan tilt handle 230, the pan tilt camera 300 moves in the dragging direction, and the pan tilt camera 300 is proportional to the drag distance. To move faster or slower.

That is, when the user places an icon of the mouse on the pan tilt handle 230 and clicks it, the program detects this and links the operation of the icon with the operation of the pan tilt handle 230. When the mouse is dragged in a specific direction while being clicked, the pan tilt handle 230 is also moved. At this time, the program detects the direction dragged from the origin and detects the coordinates of the horizontal component and the vertical component. The detected horizontal component coordinates are used as quantitative data for panning the pan tilt camera 300, and the detected vertical component coordinates are used as quantitative data for tilting the pan tilt camera 300.

In addition, the program detects the distance of the icon (and pan tilt handle) moving in the drag state and controls the rotation speed of the pan tilt camera 300 to be proportional to the distance. That is, when the distance in which the icon is dragged in the first area 220 is large, the pan operation speed and the tilt operation speed of the pan tilt camera 300 also increase proportionally.

The pan tilt handle 230 returns to the origin when the mouse is released. This is to perform additional pan or tilt operation. In addition, even if the pan tilt handle 230 is returned to the origin, the pan tilt handle 230 does not return to the original position.

For example, when the user drags the mouse to move the pan tilt handle 230 to the right end of the first region 220, the pan tilt camera 300 also continues the pan operation to rapidly rotate to the right.

In another example, when the user moves the pan tilt handle 230 only by a short distance in the diagonal direction of the first area 220 by dragging the mouse, the pan tilt camera 300 also performs a combination of pan and tilt motions. This slowly moves diagonally. Then, when the user releases the mouse click at a suitable timing while watching the pan tilt camera image 210, the pan tilt handle 230 returns to the origin, and the pan tilt camera 300 stops the pan tilt operation and continues the current position. I will shoot.

The second area 240 is provided below the first area 220 and includes a zoom adjustment scroll bar 245 displayed to move like a dragged mouse. For this purpose, the second area 240 is preferably displayed in a rectangular shape. Accordingly, when the user clicks and drags the zoom scroll bar 245 to the left (see FIG. 2), the zoom-in operation is performed on the pan tilt camera 300, and when the user drags to the right (FIG. 2), the pan tilt camera ( At 300, a zoom out operation is performed. Of course, it can be set to operate in reverse depending on the program.

When the mouse is released by the zoom adjustment scroll bar 245, it returns to the original position (center). This is to perform additional zoom in or zoom out operations.

The panoramic screen 260 is located below the pan tilt camera image 210 and is a reference screen for controlling the operation of the pan tilt camera 300. The photographing area 270 currently being photographed on the panorama screen 260 is displayed in the form of a box drawn by a dotted line, and a photographing center 275 having a "cross" shape is displayed in the center. Accordingly, the user can estimate the position of the camera while viewing the panorama screen 260, and how to combine the pan operation and the tilt operation in order to capture another area. Various operation options using the panorama screen 260 will be described with reference to FIGS. 3, 4, and 5, and a method of forming the panorama screen 260 will be described with reference to FIGS. 6 and 7.

(First function mode)

Hereinafter, a first function mode using the panorama screen 260 will be described with reference to FIG. 3. FIG. 3 is an explanatory diagram for explaining a process of moving a pan tilt camera and its image by clicking a mouse on the panoramic screen 260 of FIG. 2. As shown in FIG. 3, the user clicks on an arbitrary position on the panorama screen 260 with a mouse. The program then detects the coordinates of the click position 277.

Next, the photographing area 270 is moved so that the photographing center 275 coincides with the click position 277. Then, a rectangle drawn with a dotted line, such as the photographing area 270, is formed around the click position 277. In addition, the horizontal moving distance and the vertical moving distance of the photographing area 270 are detected within the range of the panoramic screen 260.

The program executes a pan operation of the pan tilt camera 300 based on the detected horizontal movement distance, and performs a tilt operation of the pan tilt camera 300 based on the detected vertical movement distance. Therefore, the photographing area 270 on the panoramic screen 260 and the area actually photographed by the pan tilt camera 300 are synchronized, and the captured image is displayed on the pan tilt camera image 210. As a result, the user can move and view the camera 300 by simply clicking on a desired position.

(2nd function mode)

Hereinafter, a second function mode using the panorama screen 260 will be described with reference to FIG. 4. FIG. 4 is an explanatory diagram for explaining a process of moving a pan tilt camera and its image by dragging a mouse on the panoramic screen 260 of FIG. 2. As shown in FIG. 4, when a user clicks and drags a mouse at an arbitrary position on the panorama screen 260, a rectangular box 280 made of dotted lines is drawn.

Next, when the user releases the mouse click, the photographing area 270 moves to the box 280. The program executes a pan operation of the pan tilt camera 300 based on the detected horizontal movement distance, and performs a tilt operation of the pan tilt camera 300 based on the detected vertical movement distance.

In this case, the drawn box 280 has a small side 284 and a large side 282. The program detects the length of each side to detect whether the side is a large side 282 or the side is a large side. In addition, the length value of the large side 282 is detected using the resolution on the panoramic screen 260.

The program is then scaled such that the imaging area 270 fits the large side 282 of the box 280. That is, the size of the photographing area 270 becomes smaller or larger. At this time, the program detects the rate at which the photographing area 270 becomes larger or smaller. The zoom-in or zoom-out operation of the pan tilt camera 300 is performed based on the detected ratio value.

If the size of the box 280 is smaller than the photographing area 270, the scale becomes smaller than 1, which causes the pan tilt camera 300 to perform a zoom-in operation in proportion to the scale at the moved position.

When the size of the box 280 is larger than the photographing area 270, the scale becomes larger than 1, which causes the pan tilt camera 300 to perform a zoom out operation in proportion to the scale at the moved position.

Therefore, the photographing area 270 on the panoramic screen 260 and the area actually photographed by the pan tilt camera 300 are synchronized, and the captured image is displayed on the pan tilt camera image 210. As a result, the user can click the desired position to view and move the camera 300 only by sizing the box 280 drawn by dragging to view the desired zoom in or zoom out state.

(Third function mode)

Hereinafter, a third function mode using the panorama screen 260 will be described with reference to FIG. 5. FIG. 5 is an explanatory diagram for explaining a process of moving a pan tilt camera and its image in the order of position coordinates registered in advance on the panoramic screen 260 of FIG. 2. As shown in FIG. 5, the user clicks several points on the panorama screen 260. The Arabic numerals and arrows shown in FIG. 5 indicate the click position and click order 290a, ..., 290e designated by the user. In FIG. 5, five points are exemplarily illustrated and described.

When the arbitrary position is designated and clicked as shown in FIG. 5, the program stores the coordinate values (horizontal and vertical coordinates) and the click order of the corresponding position.

Then, when a call is made by the user, the program reads the stored data and moves the current photographing area 270 to the position of the first click order 290a. The pan tilt camera 300 moves in association with the movement of the photographing area 270 as in the first function mode described above.

After a certain time has elapsed, the program moves the first click order 290a to the second click order 290b. This process is repeated until the last click order 290e. In this case, the user may set a time interval, a zoom-in / zoom-out value, a moving speed, and the like in each click order 290, or may call and execute the third function mode every predetermined time.

Through the third function mode, the user can easily observe only a specific point (for example, a window, a doorway, a corridor, etc.) requiring monitoring or security.

(Configuration of the Panorama Screen)

Hereinafter, a configuration method of the panorama screen 260 utilized in the present invention will be described in detail with reference to FIGS. 6 and 7. 6 is an explanatory diagram illustrating a principle of photographing the panoramic screen 260 using the pan tilt camera 300 and the camera used in the present invention. As illustrated in FIG. 6, the pan tilt camera 300 captures a virtual panorama photographing range 310 as a plurality of unit screens 320. The unit screen 320 is photographed in the reference zoom (1x zoom) state. This panorama shooting range 310 is determined by the range of the pan rotation and the tilt rotation. Then, the camera 300 is moved while taking pictures corresponding to the horizontal viewing angle 330 of the camera 300. When the pan rotation is completed, the camera 300 is lowered by the height of the unit screen 320 through the tilt rotation to shoot while rotating the pan again.

Therefore, the pan tilt camera 300 knows the surrounding image through the plurality of unit screens 320. This is based on the fact that the surroundings of the camera 300 (building, natural environment, road, etc.) do not change significantly. The latest panorama is taken by taking the unit screen 320 every certain time (for example, weekly, monthly, daily). Allow screen 260 to be retained.

FIG. 7 is an explanatory diagram illustrating a principle of configuring the panoramic screen 260 using the plurality of screens photographed in FIG. 6. As illustrated in FIG. 7, a series of unit screens 320 continuously photographed are combined in a predetermined order by a program and are changed into a panorama image 260. Since the combination of such still images (for example, JPEG format) is easy for those skilled in the art, a detailed combining method will be omitted.

When all of the captured unit screens 320 are combined, the size of the image (horizontal and vertical) and the size of the image file (5 Mbyte or more) become very large. Then, the size and size are scaled down so as to be displayed according to the resolution of the control window 200. The prepared panoramic screen 260 can be easily displayed on the control window 200, and does not act as a heavy load on the operation of the program.

Therefore, according to one embodiment of the present invention as described above, it is possible to provide a more convenient user interface to the user who wants to control the pan tilt camera to a desired position. Thus, it is possible to implement a zoom out operation, which is a quick move and a zoom in at an appropriate timing.

In addition, by providing a variety of interfaces for moving the pan tilt camera, and allowing the user to select the desired one can be used according to the necessary purpose. For this reason, it can be utilized suitably for security, surveillance, security, a network camera, a video conference, etc.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it will be readily apparent to those skilled in the art that various other modifications and variations can be made without departing from the spirit and scope of the invention. It is obvious that all modifications fall within the scope of the appended claims.
