Description

Technical Field

[0001] This invention relates to a modular surround-type closed-circuit television camera, specifically a modular surround-type closed-circuit television camera using an automatic lifting mechanism. Applying automatic lifting to a closed-circuit television camera not only makes it easier to remove contamination caused by dust and other pollutants, but also enables active monitoring of the monitored area without blind spots. Background Technology

[0002] Surveillance cameras are typically used for various purposes such as crime prevention, traffic control and monitoring, industrial use, and education. In particular, it has been proven that installing surveillance cameras in crime-prone areas or dangerous areas such as roads can prevent and suppress crime, ensure evidence at crime scenes, facilitate the arrest of criminals, and reduce public panic. Although, as some people have mentioned, there are issues such as infringement on the portrait rights and privacy rights of ordinary citizens, the use of surveillance cameras of various types for different purposes is showing a continuous upward trend.

[0003] Furthermore, a Closed-Circuit Television (CCTV) system for monitoring specific areas is a television system that transmits image information captured by a camera to at least a number of specific receivers, enabling a small number of specific users to obtain the information they need and displaying images for users to observe the area to be monitored according to their intended purpose. Such CCTV systems are used in a variety of wide-ranging applications, including security monitoring, industrial applications, vehicle image monitoring, and traffic management.

[0004] Such closed-circuit television (CCTV) systems have the following advantages: they can be installed in places where security is required, such as elevators, entrances and exits, parking lot entrances, pedestrian streets and playgrounds, and store the captured images or monitor them remotely in real time.

[0005] In this configuration, the camera is positioned at a high location, and when the camera needs to be inspected, maintained, or replaced periodically, operators need to use additional equipment such as aerial work platforms or ladders to access it.

[0006] However, this method of approaching cameras at heights has the following problems: it exposes operators to potential safety hazards, and there is a risk of secondary injuries from falling tools and equipment during operation. In addition, the operation time is long, and maintenance and repair costs increase.

[0007] The prior art document applied for and granted by the applicant, namely Patent Publication No. 10-198870 (publication date: June 11, 2019), entitled "Automatic Lifting Mechanism for Closed-Circuit Television Camera," is characterized by comprising: a vertically formed support column; a horizontal support rod coupled to the support column; a control panel containing a control device; a fixing unit coupled to and fixed to the horizontal support rod; a camera assembly comprising a closed-circuit television camera; and a belt connecting the fixing unit and the camera assembly. The fixing unit has an upper socket containing a plurality of upper connecting pins, and the camera assembly has a lower socket containing the same number of lower connecting pins as the upper connecting pins. The connecting pins of the upper socket and the lower socket are configured to be mutually... The upper connecting pins are configured to have a precise 1:1 correspondence, comprising: a main body fixed to the upper socket; a spring disposed within the internal space of the main body; and a pin shaft passing through the center of the main body and the spring. The pin shaft is formed as a single unit, comprising a plunger, a boundary unit, a shaft, and a contact unit. In the pin shaft, the end of the plunger connected to the lower socket is formed as a convex hemisphere. The lower socket has a concave hemisphere contact unit that is precisely connected to the end of the plunger. Two of the multiple connecting pins disposed in the upper socket are respectively disposed on both sides of the center portion near the hole. Compared to other connecting pins, the length of the automatic lifting connecting pin is shorter. The lower connecting pins disposed in the lower socket are all formed with the same structure. Two of the lower connecting pins are respectively disposed on both sides of the center portion near the hole.

[0008] The aforementioned prior art documents have the following advantages: they can securely fix the liftable camera assembly, prevent signal loss due to connection, thereby minimizing operational errors, and not only can they acquire high-quality image signals, but also, since the liftable camera assembly has a floodlight assembly, maintenance of both the camera and the floodlight assembly can be performed simultaneously.

[0009] However, when using a single closed-circuit television (CCTV) camera for filming, blind spots will appear on the sides and behind the camera, causing these areas to fall outside the monitoring area, thus making it difficult to carry out normal active monitoring. Summary of the Invention

[0040] The modular surround-type closed-circuit television camera using an automatic lifting mechanism according to the present invention is characterized by comprising: a drive unit 100, mounted on a horizontal bar 20 of a support column 10, enabling the shooting unit 200 to be raised and lowered to remove foreign objects from the first and second cameras 220 of the shooting unit 200 for adjustment by an administrator and for maintenance; and a shooting unit 200 comprising a plurality of first cameras 210 fixedly mounted to shoot around the perimeter, and a second camera 220 configured to be rotatable by an administrator, wherein the shooting unit 200 is mounted on the drive unit 100 and configured to be raised and lowered, and the lifting function of raising and lowering the shooting unit 200 to facilitate the removal of contamination caused by dust, etc., enables easy management of the first cameras 210 and the second cameras 220, and prevents the images captured by the first cameras 210 and the second cameras 220 from being distorted by foreign objects, etc., thereby enabling clear identification of pedestrians passing through the monitored area, and enabling the administrator to carefully monitor specific areas, while also enabling active monitoring of the monitored area without blind spots.

[0041] The modular surround-type closed-circuit camera according to the present invention, which comprises the above features, will be described in detail with reference to the accompanying drawings.

[0042] Figure 1 This figure illustrates a modular surround-type closed-circuit television camera using an automatic lifting mechanism according to the present invention. Figure 2 Yes Figure 1 The diagram shows an enlarged view of the main components of the drive unit and the imaging unit. Figure 3 It means Figure 2 The diagram shows the internal structure of the drive unit and the imaging unit. Figure 4 Yes Figure 2 The diagram shown is a three-dimensional representation of the first camera bracket and the first camera module separated from each other. Figure 5 Yes Figure 2 The image shown is an exploded perspective view of the first camera housing, representing an exploded view of the first camera. Figure 6 It means Figure 3 The diagram shows the state in which the angle of the first camera module is adjusted.

[0043] Reference Figures 1 to 6 To illustrate, the modular surround-type closed-circuit camera according to the present invention includes a drive unit and a shooting unit.

[0044] The drive unit 100 of the modular surround-type closed-circuit camera using an automatic lifting mechanism comprises: a drive housing 110, mounted on a horizontal bar 20 of a support 10; a bracket 121, mounted inside the drive housing 110; a reel 122, rotatably mounted on the upper part of the bracket 121 for unwinding or winding the belt 123, thereby raising or lowering the camera unit 200; a motor 124, coupled with the reel 122 rotatably mounted on the bracket 121, for unwinding or winding the belt 123; and an upper socket 125, located below the reel 122 and inside the drive housing 110, for supplying current, receiving control signals, and transmitting image signals, and the upper socket 125 having an upper connection pin 125-1.

[0045] The upper connection pin 125-1 is connected to the lower connection pin 212-3 of the housing cover 212 of the first camera housing 211, so as to receive the image signals captured by the first camera 210 and the second camera 220 or provide the current required by the first camera 210 and the second camera 220.

[0046] When the electrical signal of the control device 300 is input to the motor 124 to drive the drive unit 100, the reel 122 set on the bracket 121 is rotated by the drive of the motor 124 to unfold the belt 123, thereby raising and lowering the shooting unit 200.

[0047] The camera unit 200, which is raised and lowered by the motor 124 and the belt 123, allows the administrator to check the status of the first camera 210 and the second camera 220 from the ground and perform maintenance.

[0048] In the shooting unit 200 of the modular surround closed-circuit camera using an automatic lifting mechanism, a first camera 210, which is fixedly set to shoot around the perimeter, is located below the drive unit 100, and a second camera 220 is configured to be rotated by an administrator.

[0049] The first camera housing 211 is configured to include a housing cover 212, a transparent plate 213, a fixing plate 214, a first camera bracket 215, a first camera module 216, and a switching hub 217.

[0050] The first camera housing 211 is formed by combining two hemispherical shapes. A cover engagement protrusion 211-1 for engaging with the housing cover 212 is formed at the upper part, and a housing engagement protrusion 211-2 with threads is formed at the lower part, so that the second camera housing 221 of the second camera 220 can be threadedly engaged.

[0051] Furthermore, multiple mounting protrusions 211-3 are formed in four directions within the first camera housing 211. The first camera module 216 is fixedly mounted on the mounting protrusions 211-3, thereby enabling shooting in four directions. Support protrusions 211-4 with plate-joining grooves 211-5 are formed on the mounting protrusions 211-3 to facilitate the mounting of a transparent plate 213 that prevents the first camera module 216 from being contaminated by foreign objects.

[0052] Furthermore, a support boss 211-6 is formed on the inner periphery of the mounting protrusion 211-3, and the support boss 211-6 is in close contact with the edge of the transparent plate 213.

[0053] The transparent plate 213 is embedded in the plate mating groove 211-5 formed in the mounting protrusion 211-3 and is inclinedly positioned and supported by the support protrusion 211-4. Furthermore, the transparent plate 213 is tightly fitted around its edges by the support boss 211-6 to prevent foreign objects from flowing into the inside of the first camera housing 211 from the outside, thereby preventing the first camera module 216 from being contaminated by foreign objects or the like.

[0054] In the first camera housing 211, a fixing plate 214 is provided on the inner side, and fixing bodies 214-1 are provided in four directions of the fixing plate 214. The fixing bodies 214-1 are arranged in pairs in the four directions to fix the first camera module 216 and adjust its angle. Guide holes 214-2 are formed in the fixing bodies 214-1 to adjust the angle of the first camera module.

[0055] Furthermore, the fixed plate 214 is provided with a first camera bracket 215, a first camera module 216, and a switching hub 217.

[0056] Multiple first camera brackets 215 are provided and are positioned in four directions of the fixing plate 214, thereby setting up the first camera module 216.

[0057] The first camera bracket 215 is combined with the guide hole 214-2 of the fixing body 214-1 formed in the fixing plate 214 so that the first camera module 216 can be set at a predetermined angle.

[0058] The first camera bracket 215 has a support plate 215-1 with an inlet hole 215-2 for fixing the first camera module 216, and multiple connecting plates 215-3 are formed on both sides of the support plate 215-1 and fixed by bolts to one side of the guide hole 214-2 of the fixing body 214-1.

[0059] Multiple holes are formed in the multiple connecting plates 215-3, and bolts are connected to the multiple holes (without reference numerals). One of the bolts is connected through the fixing body 214-1, which functions as a shaft for the first camera module 216 to rotate. Another bolt is connected through the guide hole 214-2 of the fixing body 214-1 to fix the first camera module 216 in the adjusted state.

[0060] The first camera module 216 is tilted at a predetermined angle and is respectively coupled to a plurality of first camera brackets 215 disposed on the fixed plate 214. The first camera module 216 is electrically connected to the switching hub 217, thereby enabling it to input image signals to the control device 300.

[0061] The switching hub 217 is electrically connected to multiple first camera modules 216 by being fixed to a mounting plate 214 located inside the first camera housing 211 by multiple bolts, thereby providing current and receiving image signals. In addition, the switching hub 217 is electrically connected to the lower connection pin 212-3 of the housing cover 212 of the first camera housing 211.

[0062] The second camera 220 comprises the following: a second camera housing 221 disposed at the bottom of the first camera housing 211; a second camera module 222 rotatably disposed inside the second camera housing 221; a rotary motor (not shown) combined with the second camera module 222 and disposed in the first camera housing 211 to rotate the second camera module 222; and a transparent cover (not shown) selectively disposed in the second camera housing 221 to prevent foreign objects from adhering to the second camera module 222.

[0063] The second camera module 222 and the rotary motor (not shown) are electrically connected to the switching hub 217 disposed in the first camera housing 211 to receive the transmission of image signals, the supply of current, etc.

[0064] Furthermore, the control device 300 is connected to a server in a remote situation room via a network including the Internet, wireless communication network, etc., thereby transmitting images captured by the first camera 210 or inputting control signals so that the administrator in the situation room can adjust the direction of the second camera 220 to capture a specific area.

[0065] Furthermore, although not shown in the accompanying drawings, the control device 300 determines whether there are image signals from the multiple first camera modules 216 and the second camera module 222, and then inputs an error signal to the server in the situation room via the network or displays it on a monitor so that the site administrator can confirm it. The monitor may be configured to display a seven-segment display of simple errors, or it may be configured to display a screen composed of LCD and LEDs to include images and numbers to display data on the overall status of the drive unit 100 and the shooting unit 200.

[0066] The control device 300 forms a group of multiple first cameras 210 located in the front-back or left-right direction with the center of the first camera housing 211 as a reference. It extracts images of specific areas from the separately input captured images and merges the two extracted images to generate a single image.

[0067] The merged image is as follows: the image is cut into segments of a predetermined size from multiple captured images. At this time, the width of the segmented image is set based on the location where the feature points in the multiple images are integrated, and the images on both sides are cut based on the set image.

[0068] In addition, other images used for merging are set with a preset image width based on the aforementioned feature points. At this time, the set image is cut from the area that does not overlap with the preset image.

[0069] The resolution of the image segmented as described above is corrected so that the image is displayed with the same number of pixels. Feature points of the images that are in contact with each other are extracted from the corrected image and the extracted feature points are overlapped to generate a merged image from the two images.

[0070] When the administrator selects any part of the image from the merged image generated as described above, the control device 300 displays the selected part of the image on the merged image using a picture-in-picture (PIP) method.

[0071] As explained above, the merged images are not only merged in the horizontal direction, but also in the vertical direction. Such vertical merging is also carried out in the same way as described above.

[0072] In addition, in order to extract images of the objects selected by the administrator, the size and proportion of each image captured by each of the first cameras 210 can be considered, and the arrangement of the merged images can be set according to the principle of data minimization.

[0073] Furthermore, the image merging has been described based on images captured by multiple first cameras 210, but images captured by multiple first cameras 210 and second cameras 220 can also be merged. In this case, the images are usually merged in the vertical direction, but the images can also be merged in the horizontal direction depending on the administrator's selection.

[0074] Furthermore, when a special situation is captured in the first camera 210, it connects to the second camera 220. In order for the second camera 220 to capture the location, the PTZ (Pan Tilt Zoom) rotation and lens zoom function is passively activated to magnify and display the target where the special situation occurred. For the special situation that occurred, the control device 300 analyzes the image and video data and trains the pattern to perform prediction and decision-making, and trains methods such as regression, classification, and clustering.

[0075] That is, it may include artificial intelligence (AI) functions, which can generate new images based on images captured by the first camera 210 and the second camera 220, and can be trained to identify specific regions in these images, separate them and merge them into new images, etc.

[0076] Reference Figure 6 The operation of the modular surround closed-circuit television camera with an automatic lifting mechanism as described above will be explained. Figure 7This diagram illustrates the state in which the shooting unit is raised and lowered by the drive unit of a modular surround-type closed-circuit television camera using an automatic lifting mechanism according to the present invention. Figure 8 It means targeting in Figure 1 The image captured by the first camera of a modular surround-type closed-circuit television camera using an automatic lifting mechanism is shown in a diagram of a state where the images are merged vertically in a control device. Figure 9 This diagram illustrates the state in which the shooting unit is raised and lowered by the drive unit of a modular surround closed-circuit television camera using an automatic lifting mechanism according to the present invention.

[0077] Reference Figure 7 As explained, multiple images captured by the first camera 210 of the shooting unit 200 of the present invention are input to the lower connection pin 212-3 and the upper connection pin 125-1 through the switching hub 217 and transmitted to the control device 300, and the image signal captured by the second camera 220 is transmitted to the control device 300.

[0078] The image signals transmitted by the first camera 210 and the second camera 220 are transmitted via the network to a server located in a remote situation room so that the administrator can review the images.

[0079] The image displayed to the administrator of the situation room is formed as follows: multiple images are extracted from images captured by multiple first cameras 210 through a process based on a preset program, and a merged image is generated by merging the extracted multiple images.

[0080] When the administrator selects an object from the merged image, the PIP function is used to magnify and display the image based on the selected object, so that the image displayed by the PIP function can be confirmed.

[0081] Furthermore, when the administrator of the situation room operates the joystick, the signal is input to the control device 300 via the network. The control device 300 inputs the signal to the switching hub 217 via the upper connection pin 125-1 and the lower connection pin 212-3, and drives the rotation motor of the second camera 220 according to the signal, thereby enabling the second camera module 222 to capture other areas around it.

[0082] As described above, the first camera module 216 of the first camera 210 consists of four channels and captures images in the front, back, left, and right directions in a fixed manner. The second camera module 222 of the second camera 220 can monitor a specific area in detail through the operation of the situation room.

[0083] Furthermore, when the administrator inputs an electrical signal to the motor 124 of the drive unit 100 via the control device 300 in order to maintain the shooting unit 200, the motor 124 causes the reel 122 mounted on the bracket 121 to rotate and unroll the belt 123 downward, thereby moving the first camera housing 211, which is connected to the belt 123, to the ground side.

[0084] When the first camera housing 211 is separated from the drive housing 110, the lower connection pin 212-3 of the lower socket 212-2 of the housing cover 212 is separated from the upper connection pin 125-1 of the upper socket 125 of the drive housing 110, thereby cutting off the current and preventing problems caused by the current.

[0085] When the first camera housing 211 is lowered to the ground, the first camera 210 and the second camera 220 move to the ground simultaneously, enabling the administrator to confirm the status of the first camera 210 and the second camera 220.

[0086] With the first camera 210 and the second camera 220 located on the ground side, i.e. in a position convenient for the administrator to operate, the user can remove foreign objects pasted on the transparent plates 213 and transparent covers of the first camera 210 and the second camera 220, thereby preventing image distortion caused by foreign objects.

[0087] In addition, after confirming the error message displayed on the control device 300, the administrator disassembles the first camera 210 or the second camera 220 to resolve the problem corresponding to the error message.

[0088] After the administrator confirms the status of the first camera 210 and the second camera 220, the motor 124 of the drive unit 100 is driven by the control device 300 to rotate the reel 122 so that the belt 123 is wound around the reel 122.

[0089] When the belt 123 is wound by the rotation of the reel 122, the first camera housing 211 with the belt 123 is raised, and the second camera housing 221, which is connected to the first camera housing 211, is raised along with it. The housing cover 212 of the first camera housing 211 is introduced into the inside of the drive housing 110 of the drive unit 100. At the same time, the lower connecting pin 212-3 of the lower socket 212-2 is tightly attached to the upper connecting pin 125-1 of the upper socket 125 to achieve fixation.

[0090] In addition, when the lower connection pin 212-3 of the lower socket 212-2 is connected to the upper connection pin 125-1 of the upper socket 125, an electrical signal is input to the control device 300, thereby stopping the drive of the motor 124 installed in the drive housing 110, and fixing the connection.

[0091] The present invention Figure 7 This refers to the image captured by the first camera of a closed-circuit television camera, which is then merged horizontally in the control device. Although it is shown in black and white in the attached diagram, in the actual image, the left side is blue and the right side is orange, and the blue on the left and the orange on the right are merged horizontally.

[0092] also, Figure 8 It means targeting in Figure 1 The images captured by the first camera of the modular surround closed-circuit television camera using an automatic lifting mechanism are merged vertically in the control device. Although shown in black and white in the attached figure, the actual images are blue on the left and orange on the right, and merged vertically into an upper part that is blue and an lower part that is orange.

[0093] Figure 9 This diagram illustrates the state of the shooting unit being raised and lowered by the drive unit of a modular surround closed-circuit television camera using an automatic lifting mechanism according to the present invention. The drive unit 100 is mounted on the horizontal bar 20 of the support column 10, causing the shooting unit 200 to be raised and lowered in order to remove foreign objects from the first camera and the second camera 220 of the shooting unit 200 for adjustment by the administrator and for maintenance.

[0094] In addition, the shooting unit 200 consists of a plurality of first cameras 210 that are fixedly set to shoot around the perimeter, and a second camera 220 that can be rotated by an administrator, and the shooting unit 200 is set to the drive unit 100 and is configured to be able to rise and fall.

[0095] Therefore, the present invention prevents the images captured by the first and second cameras from being distorted due to foreign objects by means of the lifting function, and makes the maintenance and management of the first and second cameras easier.

[0096] As explained above, the lifting function of the camera device, which makes it easier to remove contamination caused by dust and the like, not only makes the management of the first camera 210 and the second camera 220 easier, but also prevents the images captured by the first camera 210 and the second camera 220 from being distorted by foreign objects, thereby enabling clear identification of pedestrians passing through the monitored area.

[0097] In addition, administrators can conduct detailed monitoring of specific areas and proactive monitoring of the entire monitoring area without blind spots. Therefore, it has the following advantages: preventing and suppressing crime in high-crime areas or dangerous areas such as roads, ensuring evidence at crime scenes and facilitating the arrest of criminals, reducing public panic, and thus providing pedestrians with a sense of psychological security.
