The auxiliary device for self photographing is provided with a fixing part for fixing the photographing device at the end of the rod shape to fix the photographing device, and a handle is provided on the opposite side of the rod so that the photographer can photograph the self. However, when a photographer does not simply take a photograph but rather shoots a movie by himself, it is possible to photograph the camera by fixing 'a webcam' or a 'digital camera' to the photographing device. However, There is a problem in that the same effect as the above can not be seen.

Therefore, there is a need for a person to shoot a moving picture in order to shoot a moving picture without shaking. In addition, when a person shoots moving images even though a moving image is taken, there is a great deal of wobble in the photographed image, so that it is troublesome to use an auxiliary device for photographing even if others take a photograph.

Always use the help of others or fix the camera on a tripod for video recording. However, when the photographing apparatus is fixed to a tripod or the like, there is a difficulty in photographing when the subject moves. Accordingly, there is a need for a device capable of adjusting an angle of photographing by recognizing an object in an image during photographing.

The present embodiment has an object to provide a self-photographing apparatus which can reduce unnecessary personnel consumption when photographing a moving picture, because the photographing apparatus tracks a user moving path by itself during self photographing.

As described above, according to the present embodiment, since the photographing device tracks the user moving path by itself during the self photographing operation, unnecessary personnel consumption can be reduced when photographing a moving image. According to the present embodiment, in general, when a person to be photographed is a person, since a person emits infrared rays, the camera judges where the infrared ray is emitted and automatically adjusts the angle to perform photographing.

According to the present embodiment, the self-photographing apparatus recognizes the person to be photographed which emits infrared rays, so that it is possible to photograph a moving picture without paying any other costs alone. According to this embodiment, the self-photographing apparatus is a video photographing apparatus, and can be used without any assistance of a person in shooting a single person, such as a video call or a personal broadcasting, through a smart phone, a webcam,

In the self-photographing apparatus 100, the self-photographing apparatus grasps the user's position at the time of self-photographing by one person and performs photographing. The self photographing apparatus 100 recognizes the object to be photographed based on the infrared image obtained by photographing a subject emitting infrared rays by using the infrared ray photographing unit 112 provided separately from the image photographing unit 110, It is possible to shoot.

When the user (subject) has the infrared ray radiator, the coordinate calculation unit 120 extracts the coordinates of the infrared ray source from the infrared ray image taken by the infrared ray photographing unit 112 of the self photographing apparatus 100. And then the motor is controlled by the photographing posture setting unit 140 connected to the image photographing unit 110. [ The self-photographing apparatus 100 controls the angle of the image capturing unit 110 to the position of the user due to the control of the motor.

The self-photographing apparatus 100 can be used to take a single UCC photograph or to shoot alone without help of another person. The self photographing apparatus 100 includes a motor (a 'first motor for controlling the yaw angle', a 'second motor for controlling the roll angle', a 'third motor' for controlling the pitch angle) and a wheel (moving means). When the subject is far away, the self photographing apparatus 100 can follow the subject using the provided wheels. The self photographing apparatus 100 can photograph a moving image while tracking a subject by using a motor provided when the subject moves. In other words, the self-photographing apparatus 100 drives the wheels when the distance to the subject exceeds a preset threshold value.

The self photographing apparatus 100 recognizes the distance between the object to be photographed (object) and the camera when photographing the image using the infrared ray photographing unit 112. [ The self photographing apparatus 100 automatically adjusts the photographing angle of the image photographing unit 110 so that self photographing is smoothly performed.

In general, when a person to be photographed is a person, since the person emits infrared rays, the camera judges where the infrared ray is emitted and automatically adjusts the angle to perform the photographing. The infrared ray photographing unit 112 recognizes a person to be photographed which emits infrared rays, so that a moving picture can be photographed without costing alone. The photographing posture setting unit 140 can be used as a video photographing apparatus without a help of another person by shooting a smart phone, a webcam,

Basically, when the object to be photographed is a person, the infrared rays are emitted from the human body. Therefore, the coordinate values of the light source position of the image photographed by the infrared ray photographing unit 112 are extracted and then the coordinate values are provided at the center of the image Thereby controlling the motor. When the subject to be photographed (the subject) carries the infrared ray radiator, a coordinate value corresponding to the position of the infrared ray source emitted from the infrared ray radiator is extracted using the infrared ray photographing unit 112. The self photographing apparatus 100 controls the motor so that the coordinate value is located at the center of the image so as to adjust the photographing posture so that the subject can be positioned at the center of the image.

Hereinafter, a process in which the self-photographing apparatus 100 controls the software SW will be described. The self photographing apparatus 100 processes the process of extracting an infrared light source in an infrared image and converting it into coordinates by software. In other words, the infrared ray photographing unit 112 of the self photographing apparatus 100 photographs an infrared ray image and performs an operation of extracting an infrared ray light source in the infrared ray image by software processing in the coordinate calculation unit 120. Then, the self-photographing apparatus 100 processes the process of generating an attitude control signal for controlling the attitude of the image capturing unit 110 so that the coordinates move to the center of the image. In other words, the posture control unit 132 of the self photographing apparatus 100 generates a posture control signal by software processing.

Hereinafter, a process of controlling the hardware HW by the self photographing apparatus 100 will be described. The self photographing apparatus 100 processes the process of driving the provided motor based on the attitude control signal in a hardware manner. In other words, the photographing posture setting unit 140 of the self photographing apparatus 100 controls the motor (hardware) based on the posture control signal to adjust the angle of at least one of the yaw angle, roll angle, and pitch angle, 110) controls the position of the user. In addition, the photographing posture of the image photographing unit 110 is controlled and the photographing posture of the infrared photographing unit 112 is also controlled. In other words, since the infrared ray photographing unit 112 also has the same photographing angle as that of the image photographing unit 110, the photographing posture setting unit 140 controls the motor (hardware) based on the posture control signal to calculate the yaw angle, The infrared ray photographing unit 112 is also controlled to have the same photographing angle as that of the image photographing unit 110 when the image photographing unit 110 controls the position of the user by adjusting the angle of at least one of the angles. Accordingly, even when the subject moves, the image capturing unit 110 and the infrared ray capturing unit 112 can adjust the photographing posture around the subject.

The self photographing apparatus 100 extracts an infrared light source emitted from an infrared ray radiator from an infrared ray image input from the infrared ray photographing unit 112 using, for example, an OpenCv library to extract an infrared ray light source in an infrared ray image, and converts the infrared ray light source into coordinates. Thereafter, the self-photographing apparatus 100 generates an attitude control signal for controlling the photographing posture of the image photographing unit 110. [ The self-photographing apparatus 100 controls the motor (hardware) to adjust the angle of at least one of the yaw angle, the roll angle and the pitch angle based on the posture control signal transmitted from the control board implemented with the posture control unit 132.

[ And generates a posture control signal for driving at least one of the posture control signals.

The self photographing apparatus 100 sets the posture of the image capturing unit 110 based on the posture control signal (S240). In step S240, the self photographing apparatus 100 determines whether or not at least one of the yaw angle, roll angle, and pitch angle of the image capturing unit 110 so that the coordinates corresponding to the infrared light source in the infrared image move to the center of the image, And drives at least one of the plurality of motors provided for adjusting the angle.

The image capturing unit 110 of the self photographing apparatus 100 is connected to the image capturing posture setting unit 140.

In step S250, the movement control unit 134 of the self photographing apparatus 100 controls the infrared ray photographing unit 112 to transmit the infrared ray pulse to the object. The self photographing apparatus 100 measures a distance value with respect to a target object based on arrival time of light reflected from the target object. When the distance value is out of a predetermined threshold (for example, 1 m), the self-photographing apparatus 100 controls to drive the moving means so that the distance value is within a predetermined threshold value.
