[0037] To make the objectives, technical solutions and advantages of the embodiments of the application clearer, the technical solutions in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are some but not all of the embodiments of the application.

[0038] An infrared light supplement device and identification method according to an embodiment of the application will be described below with reference to the drawings.

[0039] As shown in Figures 1-10 An infrared light supplement device according to an embodiment of the application includes a video image processing system, and further includes a camera mechanism 100, a light shielding mechanism 200 and an auxiliary mechanism 300.

[0040] The shading mechanism 200 is arranged on the camera mechanism 100, the auxiliary mechanism 300 is arranged on the shading mechanism 200, the camera mechanism 100 collects images of the target in the working environment, and brightness and angle correction are performed according to the brightness of the collected target image, so that the camera 110 is as much as possible to be more fully lighted, and to a certain extent, the camera 110 is prevented from appearing phenomena such as light halo and flare. The shading mechanism 200 plays a certain role in inhibiting stray light from entering the camera 110, avoiding the surrounding environment from interfering with the light to make the camera 110 capture a picture with light halo, and protecting the camera 110 to a certain extent.

[0041] According to some embodiments of the present application, as Figures 1-6As shown, the camera mechanism 100 comprises a camera 110, a shell 120, a light supplement assembly 130 and a connecting ring 140, the shell 120 is fixedly sleeved on the camera 110, the light supplement assembly 130 comprises an infrared light supplement lamp 131, a connecting rod 132, a threaded tube 133, a driving rod 134, a limiting tube 135 and a micro motor 136, the infrared light supplement lamp 131 is circumferentially arranged on the shell 120, one end of the infrared light supplement lamp 131 is hingedly connected to the shell 120, the other end of the infrared light supplement lamp 131 is hingedly connected to the connecting rod 132, the connecting rod 132 penetrates through the shell 120, the connecting rod 132 is circumferentially arranged, and one end of the connecting rod 132 away from the infrared light supplement lamp 131 is hingedly connected to the threaded tube 133, the threaded tube 133 is circumferentially arranged, the threaded tube 133 is threadedly sleeved on the driving rod 134, the limiting tube 135 is fixedly connected in the shell 120, the limiting tube 135 is circumferentially arranged, the limiting tube 135 is limitingly and slidingly sleeved on the threaded tube 133, the micro motor 136 is fixedly connected in the shell 120, an output end of the micro motor 136 is drivingly connected to the driving rod 134, the driving rod 134 is driven to rotate by the micro motor 136, because the threaded tube 133 is limitingly inserted in the limiting tube 135, the limiting tube 135 is fixed on the shell 120, and the driving rod 134 and the threaded tube 133 are threadedly matched, therefore, under the driving of the micro motor 136, the threaded tube 133 axially displaces on the limiting tube 135, in turn drives the connecting rod 132 to change the angle and position on the first cavity 121, the second cavity 122 and the U-shaped block 123, so that the infrared light supplement lamp 131 changes the angle along the radial direction of the shell 120 with the hingedly connected end of the shell 120 as the shaft, in turn changes the light convergence intensity and the irradiation angle when the infrared light supplement lamp 131 supplements the light for the camera 110, the connecting ring 140 is fixedly connected to the hingedly connected ends of the circumferentially arranged connecting rod 132 and the threaded tube 133, so that the circumferentially arranged plurality of infrared light supplement lamps 131 can synchronously change the angle, the limiting ring 111 is fixedly connected to the outer wall of the camera 110, the camera 110 is hingedly connected to the support 112, facilitating the adjustment of the collection range of the camera 110, the first cavity 121 is circumferentially arranged on the shell 120, the first cavity 121 is slidingly matched with the connecting rod 132, the second cavity 122 is circumferentially arranged on the shell 120, the second cavity 122 is communicated with the first cavity 121, and the second cavity 122 is slidingly matched with the connecting rod 132, the U-shaped block 123 is circumferentially fixed on the shell 120, the U-shaped block 123 is symmetrically arranged, and the U-shaped block 123 is limitingly and slidingly matched with the connecting rod 132, limiting the angle and position change of the connecting rod 132 to a certain extent, the fourth cavity 124 is circumferentially arranged on the inner wall of the shell 120, the connecting ring 140 is annularly designed, and the connecting ring 140 does not contact the camera 110 and the shell 120.

[0042] The video image processing system is used to process environmental images of the working environment captured by the camera 110. The video image processing system includes a processor and a memory storing computer programs. The processor executes the computer programs to acquire environmental images captured by the camera 110, perform grayscale correction on the environmental images, and obtain target correction parameters for the environmental images. The memory, based on its internally stored computer programs and in conjunction with the processor, determines the light intensity increment corresponding to the target correction parameters, and adjusts the light intensity output by the supplementary lighting component 130 according to the light intensity increment corresponding to the target correction parameters.

[0043] Specifically, in an exemplary embodiment of this application, a correspondence is established between at least one correction parameter and the light intensity increment. The supplementary light intensity is divided into N power levels, with the supplementary light power of each level increasing uniformly, and the power difference between adjacent levels being Δ. Figure 10 By establishing a correspondence between at least one correction parameter and the light intensity increment, the light intensity increment corresponding to the target correction parameter can be determined. Then, the light intensity output of the infrared supplementary light lamp 131 can be adjusted using the light intensity increment corresponding to the target correction parameter to provide supplementary lighting for the working environment. For ease of description, the target correction parameter is denoted as γ′. When the calculated target correction parameter γ′ < 1, the light intensity increment corresponding to the upper limit of its interval is found and increased. For example, if the target correction parameter γ′ ∈ (γn, γn-1], and the level corresponding to γn-1 is (n-1)Δ, then the supplementary light intensity of the infrared supplementary light lamp 131 is increased by (n-1) levels. If the infrared supplementary light lamp 131... If the intensity of the external supplementary light 131 is increased by (n-1) levels and exceeds the maximum intensity of the infrared supplementary light 131, then the intensity of the infrared supplementary light 131 is adjusted to the maximum. When the calculated γ′>1, the light intensity increment corresponding to the lower limit of the interval is found and reduced. For example, when the target correction parameter γ′∈(1 / γn,1 / γn-1], the intensity of 1 / γn-1 is -(n-1)Δ, then the intensity of the infrared supplementary light 131 is reduced by (n-1) levels. If the intensity of the infrared supplementary light 131 is reduced by (n-1) levels and exceeds the lowest intensity of the infrared supplementary light 131, then the infrared supplementary light 131 is turned off.

[0044] It should be noted that the drive rod 134 connected to the output end of the micro motor 136 has a threaded part at the end away from the micro motor 136, and this threaded part is threadedly engaged with the threaded tube 133.

[0045] On the other hand, embodiments of this application also provide an identification method for an infrared supplementary lighting device, comprising the following steps;

[0046] Step A: Image capture. The camera 110 captures images of people's faces within its range and transmits them to the video image processing system.

[0047] Step B: Light assistance, the infrared light supplement lamp 131 adjusts its angle according to the brightness of the face image of the person fed back by the video image processing system, and assists the camera 110 to enhance the light of the collected face of the person;

[0048] Step C: Information comparison, the video image processing system compares and identifies the face information of the collected person with the face information of the stored person, judges whether it is the information of the stored person, and feeds back the result to the control terminal.

[0049] Therefore, when the camera 110 collects the target image in the working environment, the collected image is transmitted to the video processing system, the processor in the video processing system corrects the gray scale of the environment image, obtains the target correction parameter for correcting the environment image, the memory determines the light intensity increment corresponding to the target correction parameter according to the computer program stored in the memory and the processor, adjusts the output light intensity of the infrared light supplement lamp 131 according to the light intensity increment corresponding to the target correction parameter, so that the camera 110 collects the target image more clearly, and at the same time, the micro motor 136 is started under the control of the processor, drives the driving rod 134 to rotate, so that the threaded pipe 133 moves along the axial direction of the limiting pipe 135 fixed in the shell 120, and then drives the connecting rods 132 fixed together by the connecting ring 140 to change the angle and position in the first cavity 121, the second cavity 122 and the U-shaped block 123, and further makes the multiple infrared light supplement lamps 131 hinged on the shell 120 change the angle along the radial direction of the shell 120, so that the light intensity of the infrared light supplement lamp 131 changes, and the camera 110 collects the environment image more clearly, which to some extent slows down the phenomenon of halo and flare in the image collected by the camera 110 due to the change of light angle and intensity.

[0050] In the related art, only the change of the light intensity and angle of the infrared light supplement lamp 131 will cause the image collected by the camera 110 to appear halo and flare phenomenon.

[0051] According to some embodiments of the present application, as Figures 7-8As shown, the infrared light supplementing device further comprises a light shielding mechanism 200, which comprises a driving member 210 and a light shielding ring 220. The driving member 210 comprises a driving cylinder 211, a tooth ring 212 and a gear 213. The driving cylinder 211 is sleeved on the camera 110. An annular groove is arranged on the inner wall of the driving cylinder 211, and the annular groove is in limiting sliding fit with the limiting ring 111. The side wall of the end of the driving cylinder 211 away from the micro motor 136 is designed in screw thread. The tooth ring 212 is fixedly sleeved on the driving cylinder 211. The gear 213 is in transmission connection with the driving rod 134, and the gear 213 is in engagement with the tooth ring 212. The light shielding ring 220 is sleeved on the driving cylinder 211, and the light shielding ring 220 is in screw thread fit with the driving cylinder 211. The side wall of the end of the light shielding ring 220 close to the micro motor 136 is circumferentially arranged with a plurality of protrusions 221, and the protrusions 221 are in limiting sliding fit with the fourth cavity 124.

[0052] It can be understood that when the micro motor 136 drives the driving rod 134 to rotate, the gear 213 in transmission with the driving rod 134 will drive the driving cylinder 211 to rotate on the camera 110, further causing the light shielding ring 220 in limiting sliding fit with the fourth cavity 124 and in screw thread fit with the driving cylinder 211 to displace, so that the light shielding ring 220 extends out of the shell 120.

[0053] Therefore, the infrared light supplementing device and the identification method, in use, according to the analysis of the processor in the video image processing system on the collected working environment image, control the micro motor 136 to drive the driving rod 134 to rotate, so that the driving cylinder 211 rotates, further causing the light shielding ring 220 to extend out of the shell 120, which plays a certain role in inhibiting stray light from entering the collection end of the camera 110, avoiding the interference of ambient light to cause the camera 110 to capture a picture with halo, and at the same time, playing a certain role in protecting the camera 110.

[0054] In the related art, due to the screw thread fit between the driving cylinder 211 and the light shielding ring 220, the inner wall of the light shielding ring 220 is designed in screw thread, and the inner wall of the light shielding ring 220 designed in screw thread may reflect part of the stray light entering the collection end of the camera 110, causing the image collection clarity of the camera 110 on the working environment target to be disturbed to a certain extent.

[0055] According to some embodiments of the present application, as Figure 9As shown, the infrared light supplementing device further comprises an auxiliary mechanism 300, which comprises a weakened ring 310 and a receiving ring 320. The weakened ring 310 is inserted into one end of the driving cylinder 211 away from the micro motor 136. An inner wall of the weakened ring 310 is provided with a weakened layer 311 made of rubber material to weaken the interfering light as much as possible. The receiving ring 320 is fixedly connected to one side of the weakened ring 310 away from the driving cylinder 211 and is fixedly connected to one end of the light shielding ring 220 away from the micro motor 136, so as to facilitate the light shielding ring 220 to drive the weakened ring 310 to displace in the driving cylinder 211.

[0056] Therefore, when the light shielding ring 220 is driven by the micro motor 136 to displace outward of the shell 120, the receiving ring 320 fixedly connected will drive the weakened ring 310 inserted into the driving cylinder 211 to displace synchronously, so that the weakened layer 311 on the inner wall of the weakened ring 310 leaks out, thereby weakening the stray light entering the collecting end of the camera 110 as much as possible.

[0057] Specifically, the working principle of the infrared light supplementing device and the identification method is as follows: in the process that the camera 110 collects the target image in the working environment, the collected image is transmitted to the video processing system, the processor in the video processing system corrects the gray scale of the environment image, obtains the target correction parameter for correcting the environment image, the memory determines the light intensity increment corresponding to the target correction parameter according to the computer program stored in the memory and the processor, adjusts the output light intensity of the infrared light supplementing lamp 131 according to the light intensity increment corresponding to the target correction parameter, so that the camera 110 collects the target image more clearly, meanwhile, the micro motor 136 is started under the control of the processor, drives the driving rod 134 to rotate, so that the threaded pipe 133 is displaced in the axial direction of the limiting pipe 135 fixed to the shell 120, and then drives the connecting rods 132 fixed together by the connecting ring 140 to change the angle and position in the first cavity 121, the second cavity 122 and the U-shaped block 123, further makes the plurality of infrared light supplementing lamps 131 hinged to the shell 120 change the angle along the radial direction of the shell 120, so that the light supplementing intensity of the infrared light supplementing lamp 131 to the camera 110 changes, further makes the camera 110 collect the environment image more clearly, to a certain extent, slows down the phenomenon that the camera 110 collects the image with halos and glares due to the light angle and intensity, while the micro motor 136 drives the driving rod 134 to rotate, further drives the driving cylinder 211 to rotate, further makes the light shielding ring 220 extend out of the shell 120, to a certain extent, suppresses the stray light from entering the collecting end of the camera 110, avoids the interference light from the surrounding environment to make the camera 110 capture the image with halos, and further protects the camera 110, when the light shielding ring 220 is displaced to the outside of the shell 120 under the drive of the micro motor 136, the weakened ring 310 inserted into the driving cylinder 211 is driven to displace synchronously by the supporting ring 320 fixedly connected, so that the weakened layer 311 on the inner wall of the weakened ring 310 leaks, and then weakens the stray light entering the collecting end of the camera 110 as much as possible, according to the brightness and angle correction of the collected target image, the design makes the camera 110 supplement light as much as possible, to a certain extent, avoids the camera 110 from appearing halos, glares and the like, the light shielding mechanism 200 suppresses the stray light from entering the camera 110, further avoids the interference light from the surrounding environment to make the camera 110 capture the image with halos, and protects the camera 110 to a certain extent, the auxiliary mechanism 300 cooperates with the light shielding mechanism 200 to avoid the reflection of the stray light at the capturing end of the camera 110, further ensures that the light shielding mechanism 200 avoids halos and glares,The video image processing system compares and identifies the face information of the collected person with the face information of the stored person, judges whether it is the face information of the stored person, and feeds back to the control terminal according to the comparison result, so as to complete the identification of the person in the environment target.

[0058] It should be noted that the specific model specifications of the camera 110, the infrared fill light 131, the micro motor 136, the gear ring 212 and the gear 213 need to be determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the art, so it is not necessary to be described in detail.

[0059] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be limited to the protection scope of the claims.
