Abstract

PURPOSE:To easily control the direction of a camera by providing a calculator which receives a signal from a monitor device to calculate the direction of the camera and a camera universal head controller which receives the output of the calculator to control a camera universal head. CONSTITUTION:An object and a digital map in the vicinity of this object are displayed on a touch panel 2 of a monitor device 1, and a desired position on the digital map of the object toward which the camera is directed is depressed, and then, a coordinate signal is sent to a calculator 3 from the touch panel 2. The calculator 3 calculates the command direction angle of the camera 6 in accordance with positional relations between coordinates inputted from the touch panel 2 and those of a camera universal head 4. The deviation angle between the present angle of the camera and the commanded camera angle is calculated to send a deviation angle signal to the camera universal head controller 5. This controller 5 sends a control signal to the camera universal head 4 in accordance with the input to direct the camera 6 to the desired direction. Thus, the camera is easily and automatically directed to the desired position of the object.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an eyeglass control device that is applied to a method for inputting the pointing direction of a surveillance camera of security equipment or the like.

[Conventional technology]

Conventionally, when controlling the pointing direction of a surveillance camera in security equipment, etc., an operator uses a joystick or the like on a camera pointing direction control device while watching an image on a monitor that displays the pointing direction of the surveillance camera. was.

Problem to be Solved by Invention J] When a camera operator controls the camera pointing direction using a camera pointing direction control device such as a joystick while watching a monitor displaying an image of the camera pointing direction, If the object does not have a clear target for camera pointing,
Alternatively, if the object is magnified by a zoom lens or the like and has a complicated shape, there is a problem in that the operator cannot easily confirm the pointing direction of the camera.

Furthermore, when directing the camera to an arbitrary position using a joystick, etc., it was necessary to study the relationship between the inclination angle of the joystick and the moving speed of the camera pan head.

Means to solve problems] The present invention takes the following measures to solve the above problems.

In other words, the glasses control device includes a camera, a camera platform that supports the camera, a monitor device that has a touch panel and displays a digital map of the object and its vicinity on the touch baffle, and receives signals from the monitor device. A calculator for calculating the pointing direction of the camera, and a camera pan head controller for receiving the output of the calculator and controlling the camera pan head.

[Function] With the above means, when a desired position on the digital map of the monitor device to which the camera is to be directed is pressed, a coordinate signal is input from the touch panel to the calculator. The calculator calculates the pointing direction angle of the camera based on the input coordinate signal, and sends a deviation signal from the current pointing direction angle of the camera to the camera pan head controller. The camera pan head controller controls the camera pan head in response to an input, and adjusts the camera to point at the desired location.

In this way, the camera can be easily directed to the desired position.

〔Example] An embodiment of the present invention will be described with reference to FIGS. 1 and 2.

In FIG. 1, a camera 6 and a camera platform 4 for supporting the camera are provided. Further, a camera pan head control device 5 for controlling the camera pan head 4 is provided.

Furthermore, a monitor device 1 having a touch panel 2 and displaying a digital map of the object and its vicinity on the touch panel 2 is provided. Further, the monitor device ff is connected to the calculator 3. Furthermore, the calculator 3 is connected to a camera pan head control device 5. Note that 7 in the figure is a monitor device for displaying camera images.

In the above configuration, a digital map of the target object and its vicinity is displayed on the touch panel 2 of the monitor device 1.

When a user presses a desired position on the digital map of an object to which he or she wants to point the camera, a coordinate signal is sent from the touch panel 2 to the calculator 3 as shown in FIG. Calculator 3 is touch panel 2
The command direction angle of the camera 6 is calculated from the positional relationship between the input coordinates and the coordinates of the camera pan head 4. Next, the deviation angle between the current angle of the camera 6 and the camera angle to be commanded is calculated and a deviation angle signal is sent to the camera pan head controller 5.

The camera pan head controller 5 sends a control signal to the camera pan head 4 in response to the input, and directs the camera 6 in the desired direction.

In this way, the camera can be easily and automatically directed to the desired location of the object. Additionally, since there are no devices such as joysticks that require proficiency, the camera operator does not need special training.

〔Effect of the invention〕

As explained above, according to the present invention, a camera operator can automatically point the camera in a desired direction simply by pressing a desired position on a digital map.

FIG. 1 is a block diagram of an embodiment of the present invention, and FIG. 2 is a control algorithm diagram of the embodiment.

Claims (1)

[Claims] A camera, a camera platform that supports the camera, a monitor device that has a touch panel and displays a digital map of the object and its vicinity on the touch panel, and receives a signal from the monitor device and calculates the pointing direction of the camera. and a camera pan head controller that receives the output of the calculator and controls the camera pan head.
