Description

  The present invention relates to a turning camera control system and a turning camera control method for controlling a turning camera device used in a monitoring system and the like, and a turning camera device, a camera turning method, and a camera turning program applied thereto.

  There is a case where an operation for moving a subject to be focused on within the monitor angle of view to the center of the screen is performed on the turning camera device. In the case where the operation of turning the turning camera in the vertical direction or the oblique direction and the fine adjustment of the operation are manually performed, a plurality of operations are required. Therefore, various methods for avoiding such complexity are known.

  In a general turning camera control system using a personal computer (hereinafter referred to as a personal computer), when moving an object projected on a personal computer monitor (hereinafter referred to as a personal computer monitor) screen to the center of the screen, On the personal computer side, the angle of view is calculated based on the current position coordinate data acquired from the turning camera device. Further, the amount of movement of the motor necessary to move the subject to the center of the screen is calculated on the personal computer side, and the amount of movement and the control command are transmitted from the personal computer side to the turning camera device.

  Patent Document 1 describes a camera control device that eliminates the complexity of camera operation. In the camera control device described in Patent Document 1, when a user designates a position to be centered in a photographing screen displayed on a monitor, a CPU on the computer side calculates a difference between the designated position and the center position. The camera control circuit that transfers the result and the movement command to the camera control circuit receives these pieces of information, calculates the actual movement amount, and directs the photographing optical axis of the camera in the designated direction.

  Patent Document 2 describes a surveillance camera system that displays a subject at the center position of a monitor screen. The surveillance camera system described in Patent Document 2 displays a fast-moving subject or a subject moving over a wide range at a central position on a monitor screen by controlling the directions of at least two surveillance cameras in conjunction with each other. is there.

Japanese Patent No. 34311953 (paragraphs 0008-0011, 0013-0017, FIG. 1) JP 2008-85607 A (paragraphs 0010-0013)

  In a general swivel camera control system, first, when the user clicks a monitoring point on the PC monitor screen with a mouse, the horizontal coordinate position, vertical coordinate position, and zoom position of the zoom lens are transferred from the personal computer side to the swivel camera device. An inquiry is made. When the inquiry is made, the turning camera device transmits the inquiry result to the personal computer side. On the personal computer side, when the inquiry result is received, the angle of view is calculated based on the coordinate position of the personal computer monitor screen and the optical dimensions of the zoom lens and the image sensor. Further, on the personal computer side, the movement amount of the motor necessary for moving the subject to the center of the screen is calculated, and the movement amount (coordinate data) and the control command are retransmitted from the personal computer side to the turning camera device.

  FIG. 6 is a flowchart showing the operation of a general turning camera control system. First, the turning camera device determines whether or not a command for controlling the turning camera has been received from the personal computer (step F2). When it is determined that no command is received from the personal computer (No in Step F2), the turning camera device ends the process.

  On the other hand, if it is determined that a command has been received from the personal computer (Yes in step F2), the turning camera device detects the current horizontal position (step F3) and further detects the current vertical position (step F4). . Further, the turning camera device detects the zoom position of the lens (step F5).

  The turning camera device returns coordinate data such as the detected horizontal position, vertical position, and zoom position of the lens to the personal computer (step F6). In the personal computer, the transmitted video is converted into optical data of the image sensor (step F7), and the angle of view is calculated (step F8). In the personal computer, the relative required movement amount of the motor is calculated based on the view angle calculation result (step F9). Then, the calculated result is transmitted to the turning camera device (step F10). Finally, the turning camera device turns the turning camera device by performing motor control according to the received necessary movement amount (step F11).

  As described above, in a general turning camera control system, there is a problem that the number of times of communication exchange between the personal computer and the turning camera device is increased, and the response until the start of turning is deteriorated.

  In order to solve such a problem, in the camera control device described in Patent Document 1, the distance between the designated position on the screen calculated on the computer side and the center position is transmitted to the camera side, and other calculations are performed on the camera. By doing this, the response until the camera starts turning is shortened.

  However, when the camera control device described in Patent Document 1 is used, there is a problem that a function for controlling the turning operation of the camera must be implemented in each of the camera and the computer. Specifically, the computer side needs to be equipped with a function for performing a turn instruction command according to the calculated distance, and the camera side needs to be equipped with a function for turning the camera according to the turn instruction command. is there. Therefore, when the camera control apparatus described in Patent Document 1 is used, there is a problem that the construction of a system for controlling the turning camera becomes complicated.

It is a block diagram which shows the example of the minimum structure of the turning camera apparatus by this invention. It is a flowchart which shows operation | movement of a general turning camera control system.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram showing an embodiment of a turning camera control system according to the present invention. The turning camera control system according to the present invention includes a personal computer (hereinafter referred to as a personal computer) 13 and a turning camera device 20.

  The personal computer 13 performs control to turn the shooting direction of the turning camera device 20. A personal computer monitor 12 and a mouse 14 are connected to the personal computer 13. The personal computer monitor 12 receives an image captured by the turning camera device 20 and displays the image on the screen 15. The mouse 14 is a device for designating a position to move the displayed subject. For example, the mouse 14 is used to designate an absolute position on the screen 15 in the personal computer monitor 12. Hereinafter, the absolute position on the screen 15 of the personal computer monitor 12 may be referred to as an absolute position on the personal computer monitor 12. Information on the absolute position designated by the mouse 14 is transmitted to the turning camera device 20.

  In the following description, a case where a mouse is used as an apparatus for specifying an absolute position on the screen 15 will be described. However, the device that designates the absolute position on the screen 15 is not limited to the mouse, and may be another pointing device that can designate the position on the screen 15.

  For example, a control unit (not shown) provided in the personal computer 13 detects an absolute position on the screen 15 designated as a position on the video to be moved to the center of the screen 15. The position on the video is specified by the user using the mouse 14, for example. Then, the control unit (not shown) transmits the detected absolute position to the turning camera device 20. The absolute position on the personal computer monitor 12 is set in advance according to the range of the screen 15.

  In the following description, a case where a control unit (not shown) included in the personal computer 13 transmits the absolute position designated by the mouse 14 to the turning camera device 20 will be described. The personal computer 13 only needs to be able to transmit the absolute position of the designated display image to the turning camera device 20. That is, the personal computer 13 includes a display device such as a personal computer monitor 12 that displays an image transmitted from the turning camera device 20, a means for detecting the absolute position of a subject designated by the user using the mouse 14 and the like, and the detected absolute A means for transmitting the position to the turning camera device 20 may be provided. Therefore, for example, when the personal computer 13 has a touch panel function, a control unit (not shown) included in the personal computer 13 may transmit the absolute position detected by the touch panel function to the turning camera device 20.

  The control unit (not shown) is realized by a CPU of a computer that operates according to a program. For example, the program is stored in a storage unit (not shown) of the personal computer 13, and the CPU reads the program and operates as a control unit (not shown) according to the program.

  The turning camera device 20 includes a zoom lens 1, a television camera 2, a CPU 3, a horizontal motor driver 4, a horizontal motor 5, a horizontal gear 6, a horizontal position detection encoder 7, a vertical motor driver 8, and a vertical motor driver 20. A motor 9, a vertical gear 10, and a vertical position detection encoder 11 are provided.

  The zoom lens 1 is a lens used for photographing. The television camera 2 photographs a subject via the zoom lens 1 and transfers video information to the personal computer 13. The CPU 3 is a control device that controls each control in the turning camera device 20. Specifically, when the CPU 3 receives the absolute position on the screen 15 displaying the video transmitted from the television camera 2 from the personal computer 13, the CPU 3 calculates the distance between the absolute position and the center position on the screen 15. The amount of change for turning the turning camera device 20 is determined.

  As a method for calculating the distance, for example, the range of the video transmitted by the television camera 2 and the absolute position on the personal computer monitor 12 corresponding to the range are associated with the storage unit (not shown) of the turning camera device 20. In addition, the CPU 3 may determine a change amount for turning the camera in accordance with the association. By doing in this way, CPU3 can calculate the variation | change_quantity which moves the turning camera apparatus 20 only by receiving an absolute position from the personal computer 13. FIG. Since the calculation method of the change amount is widely known, detailed description thereof is omitted.

  The horizontal motor driver 4 is a driver for horizontal turning driving, and drives the horizontal motor 5 and the horizontal gear 6 based on the calculated amount of change according to an instruction from the CPU 3. The horizontal position detection encoder 7 detects the position of the turning camera device 20 in the horizontal direction. The vertical motor driver 8 is a driver for vertical turning driving, and drives the vertical motor 9 and the vertical gear 10 based on the calculated change amount according to an instruction from the CPU 3. The vertical position detection encoder 11 detects the vertical position of the turning camera device 20. In this manner, the turning camera device 20 detects the direction in which the turning camera device 20 captures the image by the horizontal position detection encoder 7 or the vertical position detection encoder 11.

  The CPU 3 reads, for example, a program (turning control program) stored in a storage unit (not shown) of the turning camera device 20 and operates according to the program.

  FIG. 2 is an explanatory diagram showing an example of processing for moving the subject displayed on the personal computer monitor 12. In the example shown in FIG. 2, the screen 15 on the personal computer monitor 12 is divided into small areas of horizontal 32 × vertical 24. In the following description, a case where the absolute position on the screen 15 is expressed by the absolute coordinates of a small area obtained by dividing the screen 15 will be described. Note that the absolute position on the screen 15 is not limited to absolute coordinates indicating a small area obtained by dividing the screen.

  For example, when the user clicks the subject 16 displayed at the position A on the screen 15 with the mouse 14, the control unit (not shown) provided in the personal computer 13 displays absolute coordinates (vertical 3, horizontal 3) corresponding to the position A. ) Is transmitted from the personal computer 13 to the turning camera device 20 (more specifically, the CPU 3).

  When the turning camera device 20 receives the absolute coordinates, the CPU 3 causes the horizontal position detection encoder 7 and the vertical position detection encoder 11 to detect the positions of the horizontal motor 5 and the vertical motor 9. In addition to the detected horizontal position and vertical position, the CPU 3 calculates the angle of view based on the zoom position of the zoom lens 1 and the optical dimensions of the image sensor, and the absolute coordinates (vertical 3, horizontal 3) where the mouse is clicked are calculated. ) Is calculated instantaneously to move the absolute coordinates (vertical 12, horizontal 16) to the center of the screen. Then, the CPU 3 transmits the calculated turning amount to the horizontal motor driver 4 and the vertical motor driver 8. The horizontal motor driver 4 and the vertical motor driver 8 move the subject 16 to the center of the screen by driving the horizontal motor 5 and the vertical motor 9 based on the received turning amount. In this way, the CPU 3 calculates the amount of change based on the absolute position and the shooting direction.

  Next, the operation will be described. FIG. 3 is a flowchart showing an example of the operation of the turning camera device 20.

  First, the CPU 3 of the turning camera device 20 determines whether or not the absolute position on the screen 15 (for example, the absolute position coordinate A of the subject 16 in FIG. 2) has been received from the personal computer 13 (step S2). For example, the CPU 3 determines whether or not a movement instruction command including an absolute position designated from the personal computer 13 has been received. If it is determined that a command (absolute position) from the personal computer 13 has not been received (No in step S2), the CPU 3 ends the process.

  On the other hand, if it is determined that the command (absolute position) from the personal computer 13 has been received (Yes in step S2), the CPU 3 causes the horizontal position detection encoder 7 to detect the current horizontal position (step S3), thereby detecting the vertical position. The encoder 11 is made to detect the present vertical position (step S4). Further, the CPU 3 detects the zoom position of the lens (step S5).

  The CPU 3 converts data photographed by the television camera 2 into optical data of the image sensor (step S6). Then, the CPU 3 calculates the angle of view based on the horizontal position, the vertical position, and the zoom position of the lens (step S7).

  The CPU 3 calculates a relative required movement amount (change amount) of the horizontal motor 5 and the vertical motor 9 based on the received absolute position and view angle calculation result (step S8). Then, the CPU 3 causes the horizontal motor driver 4 and the vertical motor driver 8 to drive the vertical motor 9 and the vertical gear 10 based on the calculated change amount so that the horizontal motor 5 and the vertical motor 9 are centered on the screen (for example, The turning control for moving to the absolute position coordinate B) in FIG. 2 is performed.

  As described above, since the CPU 3 calculates the necessary movement amount (change amount) based on the absolute coordinates transmitted from the personal computer 13, the personal computer 13 transmits the absolute position to be shifted to the center of the screen to the turning camera device 20. That's fine. For example, when application software for controlling the turning camera device 20 is installed on the personal computer 13 side, the application software only needs to have a function of transmitting the absolute position of the position where the mouse is clicked to the turning camera device 20. That is, since it is not necessary to calculate the angle of view on the personal computer side, the system can be simplified.

  Further, in the general turning camera control system shown in FIG. 5, the number of communication between the personal computer and the turning camera device is 3 times (before step F2 in FIG. 5, between step F5 and step F6, and step 3 times between F10 and Step F11). On the other hand, according to the present embodiment, the required number of communications between the personal computer 13 and the turning camera device 20 is one time (before step S2). Thus, compared with a general turning camera control system, in this embodiment, the response is improved by reducing the time until the motor starts turning.

  In the present embodiment, the method in which the personal computer 13 transmits the absolute position of the subject clicked with the mouse 14 to the turning camera apparatus 20 and the CPU 3 moves the subject to the center of the screen has been described. However, the position where the CPU 3 moves the subject is not limited to the center of the screen.

  For example, when the user drags the mouse 14 from the absolute coordinate A to an arbitrary absolute coordinate C on the screen, the control unit (not shown) of the personal computer 13 sets the absolute coordinate A as the movement start position and the absolute position as the movement end position. The coordinates C (that is, two points of the movement start position and the movement end position) may be transmitted to the turning camera device 20. In this case, the CPU 3 may determine the amount of change for turning the turning camera device 20 by calculating the distance between the absolute coordinates A and the absolute coordinates C. The method for calculating the amount of change is the same as the method for calculating the amount of change up to the center position. By doing in this way, the personal computer 13 can perform control to turn the photographing position of the turning camera device 20 to an arbitrary position.

  As described above, according to the present embodiment, the control unit (not shown) of the personal computer 13 has the screen 15 for displaying the video captured by the turning camera device 20 at the center of the screen 15. The absolute position on the screen 15 designated as the position on the image to be moved is detected. Then, a control unit (not shown) of the personal computer 13 transmits the detected absolute position to the turning camera device 20.

  On the other hand, the horizontal position detection encoder 7 and the vertical position detection encoder 11 detect the shooting direction in which the turning camera device 20 is shooting. Then, the CPU 3 turns necessary to move the video at the position specified on the screen 15 to the center of the personal computer monitor 12 (screen 15) based on the absolute position received from the personal computer 13 and the shooting direction. Calculate the amount.

  Because of such a configuration, when a turning camera device is used, a system for controlling the turning camera device can be easily constructed.

  Specifically, according to the present embodiment, the following effects are obtained. The first effect is that it is possible to simplify a system to be constructed including application software for a personal computer. In a general turning control system, the amount of change is calculated on the personal computer side, and calculation processing related to control is performed on the camera side, so the system is complicated. However, in this embodiment, the system construction is simplified by consolidating functions for performing calculation processing.

  The second effect is that the turning response of the turning camera device is accelerated. In a general turning control system, after taking various position data from the turning camera device to the personal computer side and calculating the angle of view, a procedure for sending a necessary movement amount command to the turning camera device again has been taken. For this reason, the time required to start turning inevitably increased and the response was poor. However, in the present embodiment, the turn response is accelerated by reducing the number of times of communication exchange by giving the turn camera side calculation work and the like.

  The third effect is that since the load on the communication control line can be reduced, it is easy to transmit a command between the turning camera device and the system and to execute a turning process. As described above, in a general turning control system, since the number of times of communication is increased / decreased for one operation, the load on the communication control line is high. However, according to the present embodiment, since the number of communication exchanges per operation is only one, the load on the communication control line can be reduced. That is, it becomes easy to send a command and execute an instruction between the turning camera device and the system.

  Next, an example of the minimum configuration of the turning camera control system according to the present invention will be described. FIG. 4 is a block diagram showing an example of the minimum configuration of the turning camera control system according to the present invention. The turning camera control system according to the present invention includes a turning camera device 80 that turns an imaging direction to take an image, and a control device 90 that performs control for turning the shooting direction of the turning camera device 80.

  The control device 90 is designated as a display unit 91 (for example, a personal computer monitor 12) having a screen (for example, the screen 15) for displaying a video captured by the turning camera device 80 and a position on the video to be moved to the center of the screen. Moving position detecting means 92 (for example, a control unit (not shown) of the personal computer 13) for detecting an absolute position (for example, absolute coordinates) on the screen, and absolute position transmitting means for transmitting the absolute position to the turning camera device 80 93 (for example, a control unit (not shown) of the personal computer 13).

  The turning camera device 80 is based on the photographing direction detecting means 81 (for example, the horizontal position detecting encoder 7 and the vertical position detecting encoder 11) for detecting the photographing direction being photographed, and the absolute position and the photographing direction received from the control device 90. A change amount calculation unit 92 (for example, the CPU 3) for calculating a change amount (for example, a turning amount) in the photographing direction for moving the video at the position designated on the screen to the center of the screen of the display unit 91. The driving means 83 (for example, the horizontal motor driver 4, the horizontal motor 5, the horizontal gear 6, the vertical motor driver 8, the vertical motor 9, and the vertical gear 10) that rotates the photographing direction based on the calculated change amount is provided.

  With such a configuration, when a turning camera device is used, a system for controlling the turning camera device can be easily constructed.

  Next, an example of the minimum configuration of the turning camera device according to the present invention will be described. FIG. 5 is a block diagram showing an example of the minimum configuration of the turning camera device according to the present invention. The revolving camera device according to the present invention includes a shooting direction detecting means 71 (for example, a horizontal position detecting encoder 7 and a vertical position detecting encoder 11) for detecting a shooting direction in which a shooting is being performed, and a screen (for example, a screen) for displaying a shot image. 15) on the screen designated as the position on the image received from the control device (for example, the personal computer 13) having the display means (for example, the personal computer monitor 12) and moved to the center of the screen of the display means.
