FIGS. 1A and 1B are a schematic view and a block diagram showing a configuration of an extension detecting apparatus 100 using a camera according to an embodiment of the present invention, and FIG. 1C is a schematic view explaining the principle of the present invention.

1A and 1B, an extension detecting apparatus 100 according to the present invention includes a camera 110, an angle adjusting unit 120, a distance sensor 130, and a control unit 150 . In addition, the extension detecting apparatus 100 according to the present invention may further include a cylinder driving unit 140 and / or a display unit 170. Furthermore, the extension detecting apparatus 100 according to the present invention may further include a storage unit 160 and / or an input unit 180.

The camera 110 is installed at a position spaced apart from the ground by a predetermined height in order to photograph the subject 200. The camera 110 is installed at, for example, a height of approximately 1 m to 10 m from the ground, and photographs the subject 200. Of course, the camera 110 converts the photographed image of the subject 200 into an electrical signal and transmits the electrical signal to the controller 150.

The angle adjusting unit 120 adjusts the angle of the camera 110 toward the face of the subject 200 (e.g., the upper end of the head or the face center). The angle adjusting unit 120 is coupled to the camera 110, for example, to adjust the camera 110 at a predetermined angle in the upward and downward directions. The angle adjusting unit 120 adjusts the angle of the camera 110 from 90 ° to 90 ° with respect to a horizontal line horizontally aligned with the ground. Further, the angle adjusting unit 120 adjusts the angle of the camera 110, for example, from 0 to 360 degrees in the horizontal direction. For this operation, the angle adjusting unit 120 includes an up / down rotating motor and / or a left / right rotating motor that can rotate in up and down and / or left and right directions installed on the camera 110 However, the invention is not limited to this. Of course, the angle adjusting unit 120 operates according to the control signal of the control unit 150, and the upper and lower angles of the camera 110 are recognized and / or detected by the control unit 150, for example.

The adjustment of the angle of the camera 110 toward the face of the subject 200 (for example, the upper end of the head or the face center) may be performed by adjusting the angle of the face of the subject 200 (for example, Means that the angle of the camera 110 is adjusted in the upward and downward directions and / or the left and right directions so as to be positioned substantially in the center of the display unit 170. [ Of course, whether or not the face of the subject 200 (for example, the top of the head or the center of the face) is located substantially in the center of the display unit 170 can be determined by the image processing logic of the controller 150.

The distance sensor 130 detects the distance to the subject 200. The distance sensor 130 may be any one or more selected from among, for example, an ultrasonic sensor, a laser sensor, an infrared sensor, and the like, but the present invention is not limited thereto. The distance sensor 130 detects the distance of the subject 200 that is, for example, approximately 0.1 m to 50 m away from the camera 110 and transmits the distance to the control unit 150.

Meanwhile, the camera 110 may be installed in a cylinder drive unit 140 capable of adjusting the height. For example, the camera 110 is installed at the upper end of the cylinder driving unit 140, and the height of the camera 110 can be adjusted to approximately 1 m to 10 m. Here, the angle adjusting unit 120 may be installed between the camera 110 and the cylinder driving unit 140, but the present invention is not limited thereto.

In addition, the height of the cylinder driving unit 140 is controlled so that the angle by the angle adjusting unit 120 becomes a minimum value. At this time, the height of the camera 110 is recognized and / or detected by the control unit 150. The angle of the camera 110 by the angle adjusting unit 120 is set to the minimum value by the angle adjusting unit 120 so that the angle of the camera 110 toward the face of the subject 200 (for example, (110) is adjusted. The smaller the upward and downward angles of the camera 110 toward the face of the subject 200 (for example, the top of the head or the center of the face), the smaller the height error of the measured / computed or measured subject 200 .

Of course, in some cases, the cylinder drive unit 140 may not be provided. That is, the camera 110 is installed at a fixed height or ceiling, and can photograph the subject 200. However, in this case, the installation height of the camera 110 may be input in advance to the controller 150, and may be used in the elongation calculation of the subject 200.

The control unit 150 controls the height of the camera 110 from the cylinder driving unit 140 to the face of the subject 200 (for example, head top or face center) from the angle adjusting unit 120 The angle of the camera 110 and the distance from the distance sensor 130 to the subject 200 are received or recognized / detected to calculate the elongation of the subject 200.

Here, the controller 150 may include an image processor 151, a face detector 152, and a calculator 153. The image processing unit 151 processes the image input from the camera 110 to extract the image of the subject 200 from the background image and the face detection unit 152 extracts the image of the subject 200 from the image processed by the image processing unit 151. [ (I.e., the top edge) of the subject 200, in order to detect the face of the subject 200. In addition, the controller 150 controls the angle adjusting unit 120 such that the face of the subject 200 (in particular, the head top or the face center) is located at the center of the display unit 170. Of course, as described above, the controller 150 recognizes and / or detects the angle of the camera 110 at this time.

The calculating unit 153 calculates the height of the subject 200 based on the height of the camera 110, the angle of the camera 110, and the distance to the subject 200 as described above.

In addition, the image (full image and / or face image) and the extension information of the subject 200 may be stored in the storage unit 160 by the control unit 150.

In addition, the display unit 170 displays video and height information of the subject 200. In some cases, such a display unit 170 may not be provided to the subject 200.

The present invention may further include an input unit 180 through which an instruction to measure an elongation or information of the subject 200 can be input.

1C, when the angle [theta] of the camera 110, the height y of the camera 110, and the distance x to the subject 200 are input to the control unit 150, The extension (Y) of the subject 200 can be calculated by Equation (1).

[Equation 1]

tan (?) = (Y-y) / x

For example, when the angle? Of the camera 110 is 10 degrees with respect to the horizontal line, the height y of the camera 110 is 1 meter, and the distance x to the subject 200 is 5 meters, the height is 1.88 m Can be calculated.

tan (10) = (Y-1) / 5 == Y = 5 * tan (10) + 1

Y = 5 * 0.176 + 1 = 1.88 (m)

Although the height of the camera 110 is shown at a height lower than the height of the subject 200 in FIG. 1C, the camera 110 may be installed at a height higher than the height of the subject 200 have. Furthermore, the camera 110 may be fixedly mounted on the ceiling.

However, since the angle? Of the camera 110 becomes smaller as the height of the cylinder driving unit 140 is adjusted so that the height of the camera 110 becomes as close as possible to the height (i.e., elongation) of the subject 200, In Equation (1), the influence of the angle [theta] of the camera 110 is small, and the error of the measured or detected elongation is small. That is, in the present invention, the height of the cylinder driving unit 140 is controlled so as to minimize the upward and downward angles of the camera 110 toward the face of the subject 200 (for example, and error. In other words, in the present invention, the angle of the camera 110 toward the face of the subject 200 (for example, the edge at the upper end of the head) is within about 30 占 with respect to the horizontal line with the ground, 20 deg., More preferably within 10 deg., And still more preferably within 5 deg.. As the angle becomes smaller, the elongation error of the subject 200 to be calculated / computed or detected is further reduced.

As described above, according to the extension detecting apparatus 100 according to the present invention, the angle of the camera 110, the height of the camera 110, and the distance to the subject 200 are measured, Is accurately detected. Furthermore, the present invention can be suitably used not only for normal elongation detection but also for security purposes by allowing the elongation of the subject 200 to be calculated in real time.

2 is a flow chart showing a method of detecting extension by an extension detecting apparatus 100 using a camera according to an embodiment of the present invention. Here, the control unit 150 is basically a control subject.

At this time, the control unit 150 may control the angle adjusting unit 120 such that the face of the face, in particular, the upper edge of the head is located at the center of the display unit 170 in the captured image.

In the camera angle detection step S2, the controller 150 detects and / or recognizes the angle of the camera 110 when the face, particularly, the head of the head is located approximately at the center of the display unit 170 in the photographed image. Since the angle of the camera 110 is substantially controlled by the control signal of the controller 150, the angle of the camera 110 is recognized from the control signal, or the angle of the camera 110 Or the like.

The control unit 150 controls the cylinder driving unit 140 to minimize the angle of the camera 110 so that the height of the camera 110 is substantially equal to the height of the subject 200 Make it similar to height. Of course, the control unit 150 detects and / or recognizes the height of the camera 110 when controlling the cylinder driving unit 140. The height of the camera 110 can be recognized from the control signal or an encoder or the like installed separately in the cylinder driving unit 140 can be used for the control of the cylinder driving unit 140. [ / RTI > In addition, at this time, the control unit 150 photographs the subject 200 using the camera 110, detects a face, in particular, an edge at the top of the head from the captured image, The angle controlling unit 120 is controlled so that the edge is positioned approximately at the center of the display unit 170 and the angle of the camera 110 at this time is detected and / or recognized.

Here, when the camera 110 is installed at a fixed position without the cylinder driving unit 140, the cylinder driving unit height adjustment and detection step S3 is omitted. However, the control unit sets the installation height of the camera 110 as a constant .

In the subject distance detection step S4, the control unit 150 detects the distance from the cylinder driving unit 140 and / or the subject 200 to the camera 110 using the distance sensor 130. [

In the elongation calculation step S5, the controller 150 calculates the height of the camera 110, the angle of the camera 110, and the distance to the subject 200 acquired so far using the arithmetic unit 153, Is input to Equation 1, and the elongation of the subject 200 is calculated.

In the extension display step (S6), the control unit (150) displays the height of the subject (200) using the display unit (170). At this time, the control unit 150 may store the image of the subject 200 and the height of the subject 200 in the storage unit 160 together.

Thus, the present invention provides an extension detecting apparatus using a camera that can detect the elongation of a subject at a distance in a non-contact manner. That is, the present invention detects the elongation of the subject in a non-contact manner using the distance to the subject at a distance, the angle of the camera toward the subject's face (in particular, the top of the head or the center of the face), and the height of the camera. Particularly, the present invention adjusts the height of the camera so as to be similar to the height of the subject, thereby detecting the height of the subject more accurately. Accordingly, the present invention enables not only normal extension detection but also security camera to extract the kidney information of a person photographed in real time.
