DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] When surveillance cameras deployed in harsh outdoor environments are used, since the lens of the surveillance camera is exposed to the outside world, a lot of dust will adhere to the surface, causing unclear camera images, which directly affects the use of the camera; at the same time, in rainy and snowy weather or in an environment with large temperature differences, water stains and fog will remain on the surface of the lens of the surveillance camera, which will also cause unclear camera images; and most surveillance cameras deployed in the wild are in remote areas or installed in places that are difficult to maintain, and there is a problem that they cannot be effectively cleaned manually. In the prior art, in order to automatically clean the lens of the surveillance camera, a scraper for cleaning the lens is provided on the surveillance camera. However, when the lens is cleaned by the scraper, the lens is still relatively dirty after cleaning, that is, the cleaning effect of the lens is poor.

[0038] Reference Figures 1 to 4In a first aspect, an embodiment of the present invention provides a camera device, including a camera 10, wherein the camera 10 includes a first lens 11; a cleaning component, wherein the cleaning component includes a cleaning box 20 and a water tank 40, wherein a cleaning column 30 is disposed in the cleaning box 20, wherein a first cleaning slot 31 and a second cleaning slot 32 are disposed on the cleaning column 30, wherein the first cleaning slot 31 and the second cleaning slot 32 are both used to accommodate the first lens 11, wherein a cleaning sheet 311 is disposed on the surface of the first cleaning slot 31, and a water-absorbing sheet 323 is disposed on the surface of the second cleaning slot 32; a cleaning liquid is disposed in the water tank, wherein the cleaning liquid infiltrates the cleaning sheet 311 through a water injection component, wherein the infiltrated cleaning sheet 311 is used to clean the first lens 11, and the water-absorbing sheet 323 is used to wipe the first lens 11.

[0039] Specifically, the camera 10 can be a 5G surveillance camera, which can be installed in harsh outdoor environments, unmanned areas that are not suitable for personnel maintenance, police 5G wireless surveillance vehicles, etc. The 5G surveillance camera includes a 5G module, which can realize the communication connection between the 5G surveillance camera and the remote monitoring module, that is, the image data obtained by the 5G surveillance camera can be transmitted back to the remote monitoring module through the 5G module. The remote monitoring module can be a remote monitoring platform terminal. By setting the 5G module in the 5G surveillance camera, high transmission rate, high bandwidth and high reliability can be guaranteed during communication.

[0040] The camera device also includes a solar panel, which can power the camera 10. The first lens 11 can specifically be the outermost glass cover on the camera 10, and the first lens 11 can be hemispherical, that is, the first lens 11 can be a hemispherical shell structure. The cleaning component includes a cleaning box 20, a water tank 40, and a water injection component. The cleaning liquid in the water tank 40 can be water, or water with a detergent added. The positions of the cleaning box 20 and the water tank 40 are sufficient to not affect the shooting angle and line of sight of the camera 10 when the first lens 11 is not cleaned. The cleaning box 20 can be set on one side of the camera 10, and the water tank 40 can be set on the side of the cleaning box 20 away from the camera 10. The cleaning box 20 can be a rectangular box structure, and the cleaning box 20 has a length direction, a height direction and a width direction, and the length direction, height direction and width direction of the cleaning box 20 are perpendicular to each other. The direction from the cleaning box 20 to the water tank 40, or the direction from the water tank 40 to the cleaning box 20 is the length direction of the cleaning box 20, that is, the water tank 40 is set on one side of the length direction of the cleaning box 20. Refer to Figure 1 When the first lens 11 is not cleaned, that is, when the cleaning box 20 and the water tank 40 are placed flat, the length direction of the cleaning box 20 is as indicated by the arrow A, and the height direction of the cleaning box 20 is as indicated by the arrow B.

[0041] The cleaning box 20 includes a first accommodating cavity, the cleaning column 30 is located in the first accommodating cavity, and the cleaning column 30 is provided with a first cleaning groove 31 and a second cleaning groove 32. The cleaning column 30 may be a cylindrical structure, in which case the axis of the cleaning column 30 is consistent with the height direction of the cleaning box 20, the cleaning column 30 includes a side surface, a first bottom surface and a second bottom surface, the first cleaning groove 31 and the second cleaning groove 32 may be respectively provided on the first bottom surface and the second bottom surface, and the cleaning column 30 may be flipped to switch between cleaning the first lens 11 with the cleaning sheet 311 and cleaning the first lens 11 with the water absorbing sheet 323. Of course, in other embodiments, the first cleaning groove 31 and the second cleaning groove 32 may be spaced apart on the cleaning column 30 along the length direction of the cleaning box 20, in which case the cleaning column 30 may move along the length direction of the cleaning box 20 to switch between cleaning the first lens 11 with the cleaning sheet 311 and cleaning the first lens 11 with the water absorbing sheet 323.

[0042] The shapes and sizes of the first cleaning tank 31 and the second cleaning tank 32 match the first lens 11. When the first lens 11 is hemispherical, the first cleaning tank 31 and the second cleaning tank 32 are both hemispherical. The cleaning sheet 311 can be a cleaning sponge, such as a high-density cleaning sponge, a nano cleaning sponge, etc., which has the function of absorbing dust and stains. The water-absorbing sheet 323 can be a dry cotton cloth with good water absorption effect. The water-absorbing sheet 323 has a certain thickness, and the water-absorbing sheet 323 can absorb water stains on the surface of the first lens 11. When the first cleaning tank 31 accommodates the first lens 11, the cleaning sheet 311 covers the first lens 11 and is tightly against the first lens 11. That is, when the soaked cleaning sheet 311 cleans the first lens 11, it covers the first lens 11 and is tightly against the first lens 11, that is, the first lens 11 will press the cleaning sheet 311, so that the cleaning sheet 311 can fully absorb the dust on the surface of the first lens 11. When the second cleaning tank 32 accommodates the first lens 11, the absorbent sheet 323 covers the first lens 11 and is tightly against the first lens 11. The cleaning sheet 311 may be bonded to the surface of the first cleaning tank 31, and the absorbent sheet 323 may be bonded to the surface of the second cleaning tank 32.

[0043] The camera device provided in the embodiment of the present invention also includes a mounting seat 50, the camera head 10 is arranged below the mounting seat 50, a mounting plate 60 is arranged on the mounting seat 50, and the cleaning box 20 is rotatably connected to one side of the mounting plate 60; the cleaning component also includes a first driving member 61, the first driving member 61 is used to drive the cleaning box 20 to rotate from a rotatable state to a working state, and a first opening 21 is provided on the cleaning box 20. When the cleaning box 20 is in a rotatable state, the first cleaning slot 31 or the second cleaning slot 32 faces the first opening 21. When the cleaning box 20 is in a working state, the first opening 21 faces the first lens 11. The first opening 21 is used for the first lens 11 to pass through so that the first lens 11 extends into the first cleaning slot 31 or the second cleaning slot 32.

[0044] Specifically, the mounting seat 50 may be a rectangular plate-shaped structure, and the mounting seat 50 has a length direction, a width direction, and a height direction. The length direction of the mounting seat 50 may refer to Figure 1 The height direction of the mounting base 50 can be referred to as the direction indicated by the arrow A in FIG. Figure 1 The mounting base 50 is used to mount the camera device to the mounting position. The mounting base 50 can be as shown in FIG. Figure 1 The cleaning box 20 is installed horizontally to the installation position as shown. At this time, the cleaning box 20 is arranged horizontally, that is, in a position as shown in FIG. Figure 1 The cleaning box 20 is in the position shown in the figure. Of course, in other embodiments, the cleaning box 20 can continue to rotate upward clockwise. The camera device can also include a supporting member, which can include an electric telescopic rod and a supporting plate connected to the telescopic rod of the electric telescopic rod. When the camera 10 is working normally, that is, when the cleaning component is not working, Figure 1 The cleaning box 20 is shown in a retracted state, and the telescopic rod of the electric telescopic rod is extended so that the support plate supports the bottom of the cleaning box 20, that is, one end of the cleaning box 20 provided with the first opening 21. When the camera 10 needs to be cleaned, the cleaning box 20 moves a preset distance, and the telescopic rod of the electric telescopic rod is retracted, and the cleaning box 20 is in a rotatable state, at which time the cleaning box 20 can rotate and has enough space to rotate. Of course, in other embodiments, the mounting seat 50 is vertically installed in the mounting position, and the cleaning box 20 is vertically arranged at this time, that is, the cleaning box 20 can maintain its position unchanged under the action of gravity without a supporting member.

[0045] The camera 10 is in a retracted and protected state, and the camera 10 can actually move downward and extend, and is in an extended state. When the cleaning box 20 is in a retracted state, and when the camera 10 is in an extended state, the cleaning box 20 will not block the viewing angle and sight of the camera 10. It should be noted that when the camera 10 is working normally to shoot a video, the first cleaning slot 31 or the second cleaning slot 32 can face the first opening 21, that is, the first cleaning slot 31 or the second cleaning slot 32 can initially face the first opening 21.

[0046] The mounting plate 60 is provided with a first mounting hole, in which a first rotating shaft 62 is rotatably connected. The first rotating shaft 62 is a round shaft, and the first mounting hole is a round hole structure. The axis direction of the first rotating shaft 62 is parallel to the width direction of the cleaning box 20, and the axis of the first rotating shaft 62 is consistent with the axis direction of the first mounting hole. The cleaning box 20 is fixedly connected to the first rotating shaft 62, and the cleaning box 20 is specifically fixed to one side of the first rotating shaft 60. The first driving member 61 is connected to the first rotating shaft 62, and the first driving member 61 is used to drive the first rotating shaft 62 to rotate with its axis as the axis. The first driving member 61 may include a second motor, and the first driving member 61 can drive the cleaning box 20 to rotate with the first rotating shaft 62 as the axis through the first rotating shaft 62.

[0047] The cleaning box 20 is provided with a first opening 21 near the bottom of the camera 10. The first opening 21 is used for the first lens 11 to pass through. The first opening 21 can also be used for other parts of the camera 10 to pass through, that is, the size of the first opening 21 is larger than the maximum size of the camera 10. The cleaning box 20 can be rotated from a rotatable state to a working state. When the cleaning box 20 is in the working state, the cleaning box 20 is vertically arranged, that is, the cleaning box 20 needs to be rotated 90 degrees from the rotatable state to the working state. When the cleaning box 20 is in the working state, the cleaning box 20 will block the viewing angle and sight of the camera 10, but at this time, the first lens 11 is still outside the cleaning box 20. When the cleaning box 20 is in the working state, the first cleaning slot 31 or the second cleaning slot 32 faces the first opening 21, and the first opening 21 faces the first lens 11. The first opening 21 is used for the first lens 11 to pass through, so that the first lens 11 extends into the first cleaning slot 31 or the second cleaning slot 32. Through the above arrangement, the cleaning box 20 can be in the working state only when it is rotated, thereby avoiding the cleaning box directly being in the working state to block the viewing angle and sight of the camera 10.

[0048] The cleaning assembly also includes a first telescopic member 70, which is disposed on the mounting seat 50 and connected to the mounting plate 60. The first telescopic member 70 is used to drive the cleaning box to move from a retracted state to a rotatable state. The first telescopic member 70 is used to drive the cleaning box 20 to move from a working state to a cleaning state. During the process of the cleaning box 20 moving from the working state to the cleaning state, the first lens 11 passes through the first opening 21 and extends into the first cleaning slot 31 or the second cleaning slot 32; when the cleaning box 20 is in the cleaning state, the cleaning sheet 311 or the absorbent sheet 323 is pressed against the first lens 11.

[0049] Specifically, the first telescopic member 70 includes a first electric telescopic rod, a limit column mounting block is arranged below the mounting seat 50, a limit column 73 runs through the limit column mounting block, a connecting seat 72 is arranged below the limit column mounting block, and the first telescopic member 70 is arranged on the connecting seat 72. A baffle 71 is fixedly connected to the telescopic rod of the first electric telescopic rod, the baffle 71 is fixedly connected to the limit column 73, and a stopper is arranged at one end of the limit column 73 away from the baffle 71. The limit column 73 can move along the length direction of the mounting seat 50, and the limit column 73 cannot move anymore when it moves to the stopper contacting the limit column mounting block. The first telescopic member 70 is used to drive the cleaning box 20 to move along the length direction of the mounting seat 50. It should be noted that when the cleaning box 20 rotates or moves, the cleaning column 30 therein will rotate or move together.

[0050] Reference Figure 1 , the telescopic rod of the first electric telescopic rod is initially in a retracted state. When the camera 10 works normally to shoot a video, the cleaning box 20 is in a retracted state. Figure 1 As shown, when the cleaning box 20 is in the retracted state, the cleaning box 20 can be arranged horizontally. Of course, any state of the cleaning box 20 after continuing to rotate upward clockwise can be the retracted state. When cleaning the first lens 11, the telescopic rod of the first electric telescopic rod can be extended first, and the telescopic rod of the first electric telescopic rod will drive the baffle 71 to move, and then drive the limit column 73 to move until the block contacts the limit column mounting block. In this process, the cleaning box 20 will move in the direction away from the camera 10, so that the cleaning box 20 moves from the retracted state to the rotatable state; then the second motor is started to drive the cleaning box 20 to rotate 90 degrees counterclockwise, and contact and abut against the baffle 71, at which time the cleaning box 20 is in the working state; then the telescopic rod of the first electric telescopic rod is retracted, and the cleaning box 20 is driven to move toward the camera 10 through the baffle 71 and the limit column 73 until the telescopic rod of the first electric telescopic rod is completely retracted, so that the cleaning box 20 moves from the working state to the cleaning state, and in this process, the first lens 11 passes through the first opening 21 and extends into the first cleaning slot 31 or the second cleaning slot 32. When the cleaning box 20 is in the cleaning state, the cleaning sheet 311 or the water-absorbing sheet 323 is tightly pressed against the first lens 11. In the embodiment of the present invention, by disposing the first telescopic member 70, sufficient space can be provided for the rotation of the cleaning box 20, thereby avoiding restrictions on the direct rotation of the cleaning box.

[0051] The cleaning assembly also includes a second driving member 80, which is arranged in the cleaning box 20. A mounting sleeve 81 is provided on the side of the cleaning column 30. The second driving member 80 is connected to the mounting sleeve 30. The second driving member 80 is used to drive the cleaning column 30 to flip through the mounting sleeve 81 so that the first cleaning slot 31 or the second cleaning slot 32 faces the first opening 21.

[0052] Specifically, the second driving member 80 can be fixed on the inner wall of the cleaning box 20. The second driving member 80 includes a first motor, and the axial direction of the output shaft of the first motor is consistent with the length direction of the cleaning box 20. The side of the cleaning column 30 is provided with a mounting sleeve 81, and the mounting sleeve 81 is used to drive the cleaning column 30 to flip around the axis of the output shaft of the first motor. The first motor is used to drive the mounting sleeve 81 to flip around the axis of the output shaft of the first motor, and then drive the cleaning column 30 to flip around the axis of the output shaft of the first motor. During the flipping process of the cleaning column 30, the first cleaning slot 31 or the second cleaning slot 32 can be directed toward the first opening 21. In the embodiment of the present invention, through the provision of the second driving member 80, the switching of the first cleaning slot 31 or the second cleaning slot 32 toward the first opening 21 can be realized, and the structure is simple, occupies little space, and has a compact structure.

[0053] The cross-section of the cleaning column 30 is circular, the first cleaning groove 31 and the second cleaning groove 32 are respectively arranged on the first bottom surface and the second bottom surface of the cleaning column 30, the first lens 11 is hemispherical, the first cleaning groove 31 and the second cleaning groove 32 are both hemispherical, and the connecting line between the first center of the first cleaning groove 31 and the second center of the second cleaning groove 32 coincides with the axis of the cleaning column 30; the mounting sleeve 81 is rotatably connected to the cleaning column 30, and the cleaning assembly also includes a third driving assembly, which is used to drive the cleaning column 30 to rotate around the axis of the cleaning column 30, and the absorbent sheet 323 is also used to wipe the first lens 11.

[0054] Specifically, the cross section of the cleaning column 30 is circular, that is, the cleaning column 30 can be a cylindrical structure. When the first cleaning slot 31 or the second cleaning slot 32 faces the first opening 21, the axis of the cleaning column 30 is consistent with the height direction of the cleaning box 20. The cleaning column 30 includes a side surface, a first bottom surface and a second bottom surface, and the first bottom surface and the second bottom surface are arranged oppositely along the axis direction of the cleaning column 30. The shape and size of the first cleaning slot 31 and the second cleaning slot 32 match the first lens 11.

[0072] In a second aspect, an embodiment of the present invention provides a camera system, comprising at least one camera device as described in any one of the first aspect.

[0073] Reference Figure 5 and Figure 6 The camera system also includes a remote monitoring module, which is in communication with the camera 10 and the processing module 24 in the camera device; the remote monitoring module is used to receive image data acquired by the camera 10; determine the clarity value of the image data according to the image data; when the clarity value is less than a first preset value, send a cleaning instruction to the processing module 24, so that the processing module 24 controls the cleaning component to clean the camera 10.

[0074] Specifically, the remote monitoring module is wirelessly connected to the camera device, and the remote monitoring module is specifically wirelessly connected to the camera 10 and the processing module 24 in the camera device. The image data acquired by the camera 10 can be sent to the remote monitoring module, and the remote monitoring module can receive the image data acquired by the camera 10, and the image data can be a video or an image. After receiving the image data, the remote monitoring module can store the image data or play and display the image data.

[0075] The remote monitoring module can determine the clarity value of the image data based on the received image data. The smaller the clarity value, the less clear the image data is, indicating that the surface of the first lens 11 is covered with stains or dust, indicating that the first lens 11 needs to be cleaned. When the clarity value is less than the first preset value, the remote monitoring module sends a cleaning instruction to the processing module 24. The first preset value can be set according to actual needs, or it can be a reference image sent to the remote monitoring module in advance. After receiving the reference image, the remote monitoring module determines the clarity value of the reference image based on the reference image, and uses the clarity value of the reference image as the first preset value. The reference image is an image captured by the camera 10 under test conditions when it meets the clarity requirements.

[0076] After receiving the cleaning instruction, the processing module 24 controls the cleaning component to clean the camera 10 according to the cleaning instruction. Specifically, the processing module 24 can control the water pump 41, the drive motor, the first motor, the air intake fan 38, the first electric telescopic rod, the second motor and the heater 39 to work to clean the first lens 11 of the camera 10. In the embodiment of the present invention, the clarity value of the image data can be determined according to the image data by the remote monitoring module to determine whether the first lens 11 needs to be cleaned, and when the first lens 11 needs to be cleaned, the cleaning instruction is sent to the processing module 24, so that the processing module 24 controls the cleaning component to clean the camera 10, that is, when the first lens 11 needs to be cleaned, the cleaning component can be automatically controlled to clean the camera 10, without manually judging whether the first lens 11 needs to be cleaned, ensuring that the first lens 11 can be cleaned in time when it needs to be cleaned.

[0077] The remote monitoring module is also used to determine the first image according to the image data; convert the first image into a grayscale image; perform edge detection on the grayscale image to obtain the edge detection response value variance, and use the edge detection response value variance as the clarity value of the image data.

[0078] Specifically, determining the clarity value of image data according to image data includes: determining a first image according to the image data; converting the first image into a grayscale image; performing edge detection on the grayscale image to obtain an edge detection response value variance, and using the edge detection response value variance as the clarity value of the image data. When the remote monitoring module determines the clarity value of the image data according to the image data, it first needs to determine the first image according to the image data. When the image data is a video, the remote monitoring module can arbitrarily capture an image from the image data as the first image. After graying the first image, a grayscale image is obtained.

[0079] The grayscale image can be normalized first to obtain a normalized image, and then the Laplace operator is used to perform edge detection on the normalized image to obtain an edge detection response value, and then the edge detection response value variance is calculated based on the edge detection response value. The edge detection response value variance can be used as the clarity value of the first image, that is, as the clarity value of the image data. In the embodiment of the present invention, after determining the first image, the first image is processed accordingly to obtain the edge detection response value variance, and there is no need to process the entire image data accordingly, so the amount of calculation is small. And by converting the first image into a grayscale image; performing edge detection on the grayscale image to obtain the edge detection response value variance, the accuracy of the clarity value of the obtained image data can be guaranteed.

[0080] The remote monitoring module is also used to send a retracting instruction to the processing module 24 when the clarity value of the image data is greater than or equal to the first preset value, so that the processing module 24 controls the cleaning component to work and retracts the cleaning box 20. When the clarity value of the image data is greater than or equal to the first preset value, that is, when the image captured by the camera 10 meets the clarity requirement, the remote monitoring module can send a retracting instruction to the processing module 24, and the processing module 24 controls the cleaning component to work, so that the cleaning box 20 is switched from the cleaning state to the retracted state, so that the cleaning box 20 is retracted.

[0081] The remote monitoring module is also used to receive the first value measured by the pressure sensor 23 sent by the processing module 24; when the first value is greater than the second preset value, a protection instruction is sent to the processing module 24, so that the processing module 24 controls the second telescopic member 92 to work according to the protection instruction. In severe environments such as heavy rain or hail, the value measured by the pressure sensor 23 will increase. When the value measured by the pressure sensor 23 is greater than the second preset value, the remote monitoring module will send a protection instruction to the processing module 24, and the processing module 24 controls the second telescopic member 92 to work, that is, controls the telescopic rod of the second electric telescopic rod to retract, so as to realize automatic control of the protection of the camera 10.
