Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 to 2, a moving object tracking and automatic lighting system using a thermal imaging camera according to the present invention comprises a strut 1 erected in the vertical direction of the ground, A main installing member 3 extending in a direction orthogonal to the pillar 1, a thermal imaging camera 7 for detecting infrared thermal energy emitted from a subject in the monitored area and converting it into an electric signal, Tilting means 11 for axially rotating the thermal imaging camera 7 horizontally in the left and right direction or for axially rotating the thermal imaging camera 7 in the up-and-down vertical direction in accordance with the control signal of the control means 9 in a state of being mounted on the lower portion of the main- An auxiliary mounting member 13 disposed on the upper side of the member 3 in parallel with the main mounting member 3 in a state of being spaced apart from each other by a predetermined height and an auxiliary mounting member 13 connected to the main mounting member 3 A second pan tilting means 15 for axially rotating the auxiliary mounting member 13 horizontally in the left and right directions or rotating the shaft in the vertical direction in accordance with the control signal of the control means 9, A lighting device 17 that is illuminated in accordance with a control signal of the control means 9 in a state of being fixed to the auxiliary mounting member 13 to secure the illuminance of the area, A CCTV 19 for accurately capturing an image of a region by capturing a forward image in accordance with a signal and a second pan tilt means 19 for detecting a living body through the thermal imaging camera 7 when the thermal imaging camera 7 is stopped, The illumination device 17 and the CCTV 19 integrally coupled to the auxiliary installation member 13 are operated so as to face the creature so that the creature brightens through the illumination device 17, (Not shown) 9).

The thermal imaging camera 7 can detect infrared thermal energy emitted from a subject and convert the detected infrared thermal energy into thermal image data and output it.

The thermal imaging camera 7 has an advantage over the conventional night vision equipment in that it has excellent detection range and image quality and has an advantage that transmission observation can be performed even in a real field battle situation in which there is a smoke film, dust, or waving.

The thermal imaging camera 7 turns the preset position set in the control means 9 every predetermined time through the first pan tilt means 11 and detects the organism at the preset position.

The reason why the present invention detects living things using the thermal imaging camera 7 is as follows.

For general CCTV (19) and other image storage sensors, capture energy information of visible light band.

In this case, if sufficient illumination can not be guaranteed due to the characteristic of the visible light, it is impossible to acquire an image that can be confirmed by the human eye because the CCTV 19 or the human eye detects light reflected from living things, Because.

Under these circumstances, it is necessary to consider the environment in the forefront GOP region. It is difficult for the GOP area to be sufficiently illuminated due to its regional characteristics.

In particular, this difference is more evident in the case of nighttime situations, demonstrating that general CCTV (19) does not adequately monitor the area.

As shown in FIG. 3, the thermal imaging camera 7 includes an optical unit 21 for receiving infrared thermal energy generated from a subject, and a controller 21 for scanning the infrared thermal energy input from the optical unit 21, A thermal image detector 23 for converting the temperature of the object into an electric signal, a correction circuit 25 for correcting and equalizing the uneven response characteristics of the thermal image detector 23, And an A / D conversion section 27 for converting the thermal image signal into a digital signal and providing it to the control means 9. [

3, the first pan tilting means 11 includes a panning motor 29 for rotating the thermal imaging camera 7 horizontally in the left and right direction and a panning motor 29 for rotating the thermal imaging camera 7 in accordance with a control signal of the control means 9 A panning motor driver 31 for rotating the panning motor 29 in the normal direction or the reverse direction, a tilting motor 33 for rotating the thermal imaging camera 7 in the vertical direction and vertical direction, And a tilting motor driver 35 for rotating the tilting motor 33 in the normal or reverse direction.

1 to Fig. 2, the present invention is characterized in that, in a state of being fixed to the auxiliary mounting member 13, by emitting a laser in the direction of the living organism detected in accordance with the control signal of the control means 9, A laser launcher 37 for precisely aiming the muzzle on the auxiliary mounting member 13 and a control unit 9 for controlling the distance between the vehicle and the living creature driven in accordance with the control signal of the control unit 9, Further comprising a distance measuring means (39) for providing the measured distance to the target (9) so as to utilize the measured distance when capturing the target aiming point when shooting the rifle, and said control means (9) If the living creature is detected through the thermal imaging camera 7, the laser launcher 37 and the distance measuring means 39, which operate the second pan tilt means 15 and are integrated with the auxiliary installation member 13, The And the laser launcher 37 is operated so as to aim the laser with the detected living organism. The distance between the living body detected by the distance measuring means 39 and the distance measuring means 39 is measured to determine the distance Use it for target aiming at rifle shooting.

At this time, both the CCTV 19 mounted on the auxiliary mounting member 13, the illuminator 17, the laser launcher 37, and the distance measuring means 39 are all connected to the living organism The center coordinates of the CCTV 19, the lighting device 17, the laser launcher 37, and the distance measuring means 39 must all point in the same direction.

If the living body is captured in the preset area by the thermal imaging camera 7, the second pan / tilt unit 15 is used to measure the distance between the CCTV 19, the illuminator 17, the laser launcher 37, Moves the means 39 to the coordinates at which the organism is captured.

The illuminating device 17 is for securing the illuminance of the area, and the distance measuring means 39 varies the target aiming point according to the distance when shooting the rifle, in order to refer to the measured distance information.

Also, the laser launcher 37 is used to accurately aim the target, and the CCTV 19 is used to secure accurate images at that time.

The operation of the present invention will be described in more detail with reference to FIG.

The flow of the initial system starts with the preset movement of the thermal imaging camera 7.

Set up a certain number of areas that you want to detect before using the camera presets.

Thereafter, the thermal imager 7 moves to the set position through the preset function at a predetermined time, and when the living organism is detected in the preset, the thermographic camera 7 magnifies the region with the thermal imager 7, The lighting device 17, the laser launcher 37, and the distance measuring means 39 are pointed to by the CCTV 19,

Since the coordinate axes of the CCTV 19 mounted on the auxiliary mounting member 13 and the illumination device 17, the laser launcher 37, and the distance measuring means 39 are different from each other, An actual measurement process for unifying these coordinate axes must be performed before the system is started.

On the other hand, the detection of living things follows the following method.

Due to the characteristics of the thermal imaging camera 7, the life forms differ from the ambient temperature, and the information is output as image information.

At this time, when the temperature is high at daytime or at summer, the temperature of living body may be similar to the temperature around living body. Detecting life with temperature only can raise the malfunction rate because of this characteristic.

In order to eliminate such a disadvantage, the living body is sensed by using the temperature information of the thermal imager 7 and the inter-frame difference information.

Therefore, as shown in Fig. 5, the control means 9 controls the control unit 9 to change the pixel value of the previous frame from the pixel value of the current frame input from the thermal imaging camera 7 when the thermal imaging camera 7 is stopped, Is judged to be a living pixel as a foreground pixel if the value is greater than the reference value set in the control means (9), whereas it is determined as a background pixel if it is smaller than the reference value set in the control means (9).

6, the control means 9 is a second embodiment of life detection, in which all the pixel values input from the thermal imaging camera 7 when the thermal imaging camera 7 is stopped, Is greater than the lower limit value stored in the control means (9) and smaller than the upper limit value, the pixel value inputted from the thermal imaging camera (7) is larger than the lower limit value stored in the control means (9) If the pixel value inputted from the thermal imaging camera 7 is not larger than the lower limit value stored in the control means 9 and is not smaller than the upper limit value, it is determined as a background pixel to detect the organism.

On the other hand, in the present invention, it is necessary to premise that the infrared camera 7 should not move when detecting living organisms to detect living things using the frame difference.

However, the present invention is a structure in which the thermal imaging camera 7 continuously moves to a preset position through a preset function.

Therefore, the present invention can detect life by using the accurate frame difference technique only when there is an assumption that the thermal imager 7 is completely stopped after the thermal imager 7 is moved to a preset position through the preset function.

To satisfy this assumption, we can check whether the current camera is moving by using the following algorithm for each image.

Contrast is a value that determines how widely the pixel values in an image are distributed.

If the camera is out of focus or the camera is in motion, blurring is essential due to the nature of the image.

Compared to normal state image and blurred state image, the contrast value of normal state is larger.

The presence or absence of the movement of the thermal imaging camera 7 is determined using this feature.

At this time, it is meaningless to extract the contrast value for the entire region of the image photographed by the thermal imaging camera 7. [

This is because blurring that occurs when the actual focus is not in focus and when the camera is moving appears in the center of the captured image.

For this reason, the contrast value is extracted for a certain region of the image center.

As shown in FIGS. 7 and 8, the control means 9 controls the operation of the thermal imaging camera 7 in order to determine whether the thermal imaging camera 7 is moving or stopped, The contrast value is extracted.

The contrast value

And the control means 9 determines that the thermal imaging camera 7 has stopped if the contrast value is higher than the reference value set in the control means 9. [

In this case, M in Equation (1) is the size of the X-axis for a certain region in the center of the image, N is the size of the Y-axis for a certain region in the center of the image, The coordinates of the pixel.

I is the brightness value, and AI is the average brightness value.

The control means (9) performs the calculation of Equation (1) every frame.

At this time, a contrast value corresponding to each frame of the calculation result is shown in a graph as shown in FIG.

In the graph shown in FIG. 8, a peak area means an area where the camera does not move.

As mentioned above, GE Genetic algorithm is used as an optimization algorithm to find the area where the camera does not move.

On the other hand, the present invention is characterized in that the CCTV 19 mounted on the auxiliary mounting member 13, the illuminator 17, the laser launcher 37, and the distance measuring means 39, This is because the thermal imaging camera 7 is mounted on the first pan tilt means 11 and the CCTV 19, the illuminator 17, the laser launcher 37 and the distance measuring means 39 Tilt means 15 through the auxiliary mounting member 13. The second pan /

In order to unify the coordinate system of the thermal imaging camera 7 and the coordinate system of the CCTV 19, the illuminator 17, the laser launcher 37 and the distance measuring means 39, distortion correction in the thermal imager 7 is first required Do.

First, the control means 9 controls the thermal imaging camera 7 and the thermal imager 16 to unify the coordinate system of the CCTV 19, the illuminator 17, the laser launcher 37 and the distance measuring means 39, Corrects the distortion of the image photographed from the first pan tilt means (7), and corrects the coordinate axes between the first pan tilt means (11) and the second pan tilt means (15).

Generally, a camera-based image capturing sensor uses a lens, which causes image distortion due to lens bending.

In this case, image distortion inevitably occurs in other areas than the center of the image, so it is necessary to correct the distortion of the thermal imaging camera 7 that detects living things.

For this purpose, the coordinate correction operation in the thermal imaging camera 7 is performed. In this case, general coordinate correction in the camera is performed, and the corrected coordinate result is stored in a lookup table to reduce the calculation time in the subsequent processing.

Next, a coordinate axis correction operation between the first pan tilt unit 11 and the second pan tilt unit 15, on which the thermal imaging camera 7 is mounted, is performed.

At this time, when the CCTV 19, the illuminator 17, the laser launcher 37, and the distance measuring means 39 are installed on the auxiliary mounting member 13, the CCTV 19, The laser launcher 37, and the distance measuring means 39 must be unified.

Since the CCTV 19, the illuminator 17, the laser launcher 37 and the distance measuring means 39 are installed in the auxiliary mounting member 13 in the longitudinal direction of the auxiliary mounting member 13, the CCTV 19 And the center coordinates of the illuminator 17, the laser launcher 37, and the distance measuring means 39 all point in the same direction.

When the operation is completed, the coordinate system between the first pan tilt unit 11 and the second pan tilt unit 15 is unified before the present invention is driven. The first pan tilt unit 11, 10-0574697 "filed by the present applicant and registered in order to unify the coordinate system between the first pan tilting means 15 and the second pan tilting means 15, Camera correction method "

In order to unify the coordinate system between the first pan tilting means 11 and the second pan tilting means 15, the control means 9 controls the operation of the first pan / (P), a tilt (T), a zoom (Z), and a focus (F) lookup table are generated and stored in the lookup table. (Z) and the focus (F) to conform to the CCTV (19).

At this time, if the living body is detected in the image input through the thermal imaging camera 7, the control means 9 controls the CCTV 19 so that the living body is picked up from the image picked up by the thermal imaging camera 7, Tilt, zoom, and focus values of a lookup table corrected to be suitable for controlling the second pan / tilt means 15 so as to photograph the creature through the CCTV 19, It is possible to brightly illuminate the living body by using the lighting device 17 pointing in the same direction.

Since the laser launcher 37 and the distance measuring means 39 indicate the same direction as the CCTV 19, when the CCTV 19 faces the living body by the second pan tilt means 15, The distance between the creature and the distance measuring means 39 can be measured by the distance measuring means 39. [

In the moving object tracking and automatic lighting control system using the thermal imaging camera according to the present invention, when the living body is detected through the thermal imaging camera 7 while the thermal imaging camera 7 is stopped, The illumination device 17 and the CCTV 19 which are integrally coupled to the auxiliary installation member 13 by operating the means 15 face the coordinates at which the living organism is detected, And can shoot the living thing detected through CCTV (19).

Therefore, in the moving object tracking and automatic lighting control system using the thermal imaging camera according to the present invention, when a living thing is detected through the rotation type thermal imaging camera 7, the living being detected through the thermal imaging camera 7 is magnified At the same time, the CCTV 19 and the lighting device 17 point the coordinates of the area where the living organism is detected, so that the shape of the living organism can be grasped more accurately.

The distance measuring sensor and the laser launching device indicate the coordinates of the area where the living organism is detected. Thus, the distance measuring means is used to grasp the standard aiming point which varies according to the distance when shooting the rifle, You can also aim accurately.
