Abstract

PURPOSE:To enable a photographer to simply attain automatic tracking to a pickup object with a safe state by storing the position of an airframe of an aircraft and controlling the direction of a television camera based on a moving direction of the airframe, moving quantity and data of rotation in every direction. CONSTITUTION:When a TV camera 6 catches an object and a controller 7 is set to the tracing mode, a control device 4 stores data of a rotary angle and an inclination and an object distance data from a range finder 3 are stored for an object position and a reference position of an airframe is calculated in addition to an aircraft altitude data from an altitude meter 2 and the result is stored. When the aircraft is moved and rotated, the control device 4 receives data of the moving direction, the moving quantity and the rotating quantity of the airframe from a giro compass 1 to calculate the direction of the object with respect to the airframe from a current position and traces the object by moving a universal head 5 into the direction. Thus, the safe operation is implemented in the airframe such as a helicopter and a fixed object on ground is traced automatically.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a television camera for aerial photography that is used by being attached to an aircraft such as a rotary wing aircraft (hereinafter referred to as a helicopter).

BACKGROUND OF THE INVENTION In recent years, the need for aerial television cameras has increased as rotary-wing aircraft are increasingly being used in television reporting for faster coverage.

A conventional aerial photographing method using a television camera will be described below.

FIG. Helicopter ○, l: They were taking pictures on board.

Problems to be Solved by the Invention However, in the above-mentioned conventional method, the photographer is exposed to a very dangerous situation because the photographer climbs onto the body of the helicopter to take the photograph. Also, narrow helicopter
In order to hold the heavy television camera a onboard the aircraft,
In addition to being difficult to move, helicopter 〇 was always moving, so it was difficult to follow and photograph fixed targets.

The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a television camera device for aerial photography that can be safely operated inside a helicopter or the like and can automatically track a fixed target on the ground.

Means for Solving the Problems In order to achieve the above object, the aerial photography television camera device of the present invention comprises a gyrocombust, an altimeter, a distance meter, a rotary table, and a television camera attached to the rotary table. , means for calculating and controlling using data from the gyro compass, altimeter, distance meter, and rotary table, and manual control means.

Function The present invention stores the target position based on the orientation of the rotary table and rangefinder data, stores the height of the helicopter based on the altimeter data, and uses the position based on the above data as a reference point. When the aircraft moves, it receives data on the moving direction, distance, and angle from the gyro compass, calculates the position of the target relative to the aircraft at that aircraft position, and controls the rotating platform in the calculated direction. You can move the camera and track the target.

Embodiment Hereinafter, an aviation television camera apparatus according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the system configuration of a television camera device for aerial photography in one embodiment of the present invention. As shown in the figure, a control device 4 that performs calculations and controls based on measurement data includes a gyro compass 1 that outputs aircraft position data such as the aircraft rotation angle, aircraft movement direction and movement amount, and
An altimeter 2 that outputs aircraft altitude data, a rangefinder 3 that outputs distance data to a target, a rotating table 6 that outputs data such as rotation angle and dip angle, and a controller 7 that controls the entire device through the control device 4. It is also connected to the rotary table 5 and the television camera 6 (hereinafter referred to as TV camera) attached to the rotary table 6 to receive control data such as direction control and camera control. Connected to give. The video signal from the TV left camera is connected to a monitor 8 and a video recording device 9 (hereinafter abbreviated as VTR). FIG. 2 is also a diagram showing how the television camera device for aerial photography is attached to the fuselage. As shown in the figure, a rotary table 6 on which a TV camera e is attached is attached to the lower surface of the exterior of the fuselage.

The operation of the aerial photography television camera device according to an embodiment of the present invention configured as described above will be explained below with reference to FIGS. 1 to 6.
While viewing the image from the V left camera on the sonicator 8, operate the controller 7 to operate the rotary base 6 to capture the target with the TV left camera, and set the controller 7 to tracking mode. The target position is stored using data on the rotation angle and inclination angle, and the target object distance data from the distance meter, and the reference position of the aircraft is calculated and stored by adding the aircraft altitude data from the altimeter 2.

As the aircraft moves and rotates, the control device 4 receives data on the moving direction, amount of movement, and amount of rotation of the aircraft from the gyro compass 1 as shown in Figures 3 and 4, and determines the target for the aircraft from its current position. Tracking can be performed by calculating the direction and moving the rotary table 6 in that direction.

The above operations are performed continuously in response to the movement of the aircraft, and the TV left camera continues to hold the target within its screen even as the aircraft moves.

If necessary, you can perform automatic tracking by operating the controller 7, or change the camera angle by manual operation depending on the shooting intention while automatically tracking, or change the camera angle while tracking the target at the center of the screen. It is also possible to create a visual expression in which the camera rotates as the aircraft rotates, or it is also possible to switch to manual mode and operate the camera using the controller 7.

In addition, we explained the case of application to a helicopter earlier, but
Naturally, it can also be used in general aircraft, airships, etc.

Effects of the Invention As is clear from the above embodiments, the present invention memorizes the position of the aircraft body and controls the direction of the television camera based on data on the direction of movement, amount of movement, and rotation of the aircraft in all directions. This is an excellent aerial photography television that allows the photographer to easily automatically track the shooting target in a safe condition, allowing the photographer to concentrate on focusing, and also allows manual operation if necessary. It is possible to realize a camera device.
