[0003] Before using an infrared thermal imager to photograph a target, it's necessary to identify the target's identity in visible light, thereby matching the target's identity with the infrared thermal image. However, this existing approach requires the camera to have both visible light and infrared thermal imaging capabilities, with the ability to quickly switch between the two modes, resulting in high equipment costs.

It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0031] Example 1
[0032] Figure 1 A flowchart of an identity recognition method based on infrared thermal imaging is provided for the first embodiment of the present invention. This embodiment is applicable to situations where identity information is recognized based on infrared thermal imaging. The method can be executed by an infrared recognition system, or by an identity recognition device based on infrared thermal imaging. The identity recognition device based on infrared thermal imaging can be implemented in the form of hardware and / or software, and can be configured in an electronic device with data processing capabilities. Figure 1 As shown, the method includes:
[0033] S110: Acquire an infrared image that matches the target to be identified.
[0034] The technical solution of the embodiment of the present application can identify the identity information of the target to be identified and the infrared thermal image information that matches the identity information. The infrared thermal image information can reflect the temperature and other information of the target to be identified. The acquisition and processing of infrared thermal image information is existing technology and will not be repeated in the embodiment of the present application.
[0035] Among them, the target to be identified includes but is not limited to materials, equipment, semi-finished products, products, etc. The infrared image includes the identity identification of the target to be identified, and the identity identification includes multiple information base points with display status and / or hidden status. In the embodiment of the present application, the identity identification can reflect the identity information of the target to be identified, including but not limited to the number information, location information, life information, task information, process information, status information, inspection information, remarks information, etc. of the target to be identified. The information base points in the display state can reflect different identity identifications through different permutations and combinations. The information base points in the hidden state and the information base points in the display state are contrasted in the infrared image, which can highlight the information base points in the display state.
[0036] Specifically, an infrared image matching the target to be identified is acquired through the infrared recognition system, and subsequent operations are performed on the infrared image. Alternatively, the infrared image is stored as infrared data and re-read in subsequent steps. This embodiment uses infrared images to identify the target's identity information, thereby preventing differences in visual conditions from affecting the accuracy of identity recognition. This greatly improves the adaptability of identity recognition to various environments, particularly those with dim or dusty conditions.
[0037] In an embodiment of the present application, optionally, the information base point in the display state is an information base point in a hollow form, and the information base point in the hidden state is an information base point in a solid form; the identity identifier is set to be a preset distance away from the surface of the target to be identified.
[0038] In this solution, the identity marker can be made of a thermal insulation material or a mixed material including thermal insulation. The information base point in the display state is configured as a hollowed-out portion. Since infrared waves can penetrate through the hollowed-out portion, the infrared recognition system identifies the hollowed-out portion as the information base point in the display state. The information base point in the hidden state is configured as a solid portion. This portion can block infrared waves, and the infrared recognition system identifies the solid portion as the information base point in the hidden state.
[0039] Among them, the preset distance can be determined according to actual conditions, and the embodiment of the present application does not limit this. In this solution, because the target to be identified has infrared radiation, it may be mistakenly judged by the infrared recognition system as an information base point in the display state under special circumstances, so the identity identifier is set to be a preset distance away from the surface of the target to be identified to avoid this problem. In the embodiment of the present application, optionally, the information base point in the display state is an information base point in the form of a physical entity with an emissivity of a first emissivity, and the information base point in the hidden state is an information base point in the form of a physical entity with an emissivity of a second emissivity; wherein, the first emissivity is greater than the second emissivity; the identity identifier is set to be a preset distance away from the surface of the target to be identified, or the identity identifier is set on the surface of the target to be identified.
[0040] The first emissivity and the second emissivity can be determined based on actual conditions and are not limited in this embodiment of the present application. In this solution, two materials with different emissivities are used to represent the display state and the hidden state, respectively. The material with a higher emissivity represents the display state, and the material with a lower emissivity represents the hidden state. The difference between the first emissivity and the second emissivity should be as large as possible to facilitate the distinction between the display state and the hidden state during subsequent image recognition.
[0041] In this embodiment, if the emissivity of the surface of the target to be identified is distinguishable from the first emissivity and the second emissivity, the identification marker can be set at a preset distance from the surface of the target to be identified, or the identification marker can be set on the surface of the target to be identified. If the emissivity of the surface of the target to be identified is indistinguishable from the first emissivity or the second emissivity, the identification marker can be set at a preset distance from the surface of the target to be identified.
[0042] In an embodiment of the present application, optionally, the information base point in the display state is a hollow information base point, and the information base point in the hidden state is a hollow information base point with a base point baffle installed; the identity identifier is set to be a preset distance away from the surface of the target to be identified.
[0043] The information base points at the base point baffle will be identified as hidden information base points. The present embodiment does not limit the specific materials used for the base point baffle. In this solution, because the target to be identified emits infrared radiation, it may be mistakenly identified as an information base point in the displayed state by the infrared recognition system under special circumstances. Therefore, the identity marker is set at a preset distance from the surface of the target to be identified to avoid this problem.
[0044] It should be noted that the base point baffle can be configured to be removable, and the connection between the information base point and the base point baffle can be a removable fixed connection. This configuration ensures both reliable connection between the information base point and the base point baffle and convenient removal. By adding or removing the base point baffle from the hollowed-out information base point, the specific content of the identity information can be changed, making it more convenient to change identity information and enabling flexible configuration of identity information.
[0045] S120: Perform image recognition on the infrared image to determine information base points of each state in the infrared image as a display state.
[0046] Image recognition can be performed using neural networks, clustering algorithms, and various machine learning algorithms. Specifically, the infrared recognition system preprocesses the infrared image and then performs image recognition on the infrared image to identify information base points whose status is display status. Furthermore, infrared image preprocessing includes, but is not limited to, performing graphic rendering, image enhancement, image noise reduction, highlighting the image subject, improving image brightness, changing color distribution, and enhancing contrast. The embodiments of the present application can use any one or more of these methods to preprocess the infrared image.
[0047] In the embodiment of the present application, the information base points exist in the infrared image, and image recognition needs to be performed on the infrared image to eliminate other interfering information and extract the information base points of each state as the display state.
[0048] S130, determining the identity information of the target to be identified according to the arrangement of the information base points in the display state.
[0049] The arrangement of the information base points of each state can be determined according to actual conditions and is not limited in this embodiment of the present application. The specific content of the identity information is not limited in this embodiment of the present application, and the content that the identity information may include has been explained in the specification and will not be repeated here. It should be noted that the type of identity information can be one or more combinations of Chinese characters, letters, numbers, symbols, and pictures.
[0050] For example, the arrangement of information base points in each display state can be divided into two directions. As shown in Figure 2(a), the arrangement of information base points in each display state can be horizontal arrangement and vertical arrangement. As shown in Figure 2(b), the arrangement of information base points in each display state can be circular arrangement and radial arrangement.
[0051] Specifically, the identity information of the target to be identified is determined according to the arrangement of the information base points in each display state, and the identity information is associated with the infrared thermal image information and stored for easy subsequent viewing and calling.
[0052] This embodiment eliminates the limitation on the number of targets to be identified by setting information base points in either visible or hidden states and transmitting identity information through permutations and combinations of these base points. This significantly increases the information density of identity information, meeting the needs of thermal imaging data informatization. For example, types of identity information may include, but are not limited to, device name, device number, service life, inspection records, and task shift information. This identity information can serve as a data source for subsequent device management.
[0053] The technical solution of the embodiment of the present application obtains an infrared image that matches the target to be identified; performs image recognition on the infrared image to determine the information base points in each state of the infrared image that are in the display state; and determines the identity information of the target to be identified based on the arrangement of the information base points in each state of the display state. This technical solution obtains the identity information of the target to be identified based on infrared thermal imaging, solving the problem in the prior art that requires the shooting equipment to have both visible light shooting functions and infrared thermal imaging shooting functions. In addition, in complex environments such as those with smoke and dust obstructions or high temperatures, electromagnetic waves in the infrared band have stronger penetration than visible light bands, resulting in clearer images and improved accuracy of identity recognition.
[0054] Example 2
[0055] Figure 3This is a flowchart of an identity recognition method based on infrared thermal imaging provided by the second embodiment of the present invention. This embodiment is optimized based on the above embodiment. The specific optimization is as follows: the infrared recognition system includes an infrared shooting system, an image processing system, and an information recognition system.
[0056] like Figure 3 As shown, the method of this embodiment specifically includes the following steps:
[0057] S210 , scanning the target to be identified by using an infrared shooting system to obtain infrared data matching the target to be identified.
[0058] In an embodiment of the present application, an infrared recognition system includes an infrared camera system, an image processing system, and an information recognition system. The infrared camera system can capture images in the infrared band and includes, but is not limited to, an infrared camera and a camera protection device. Furthermore, the infrared camera of the infrared camera system is located in the camera protection device, which can be equipped with a cooling device and a purge device for cooling and cleaning the infrared camera. The image processing system can process image data; for example, the image processing system can generate an infrared image based on the infrared data. The information recognition system can process, analyze, and understand the image using a computer to identify the identity information of the target to be identified.
[0059] The infrared image includes the identity mark of the target to be identified, and the identity mark includes a plurality of information base points in a display state and / or a hidden state.
[0060] In the embodiment of the present application, optionally, the identity identifier further includes a positioning base point whose status is a display status; the positioning base point is used to locate the identity identifier.
[0061] The positioning base point can be set outside or at the edge of the identity marker, and the positioning base point can be different from the information base points other than the positioning base point in shape and / or size. In this solution, the positioning base point allows the identity marker of the target to be identified to be quickly located during subsequent image recognition of the infrared image, thereby increasing the image recognition speed.
[0062] In an embodiment of the present application, further, the identity identifier also includes a correction base point whose state is a display state; the correction base point is used to form an error correction matrix to improve the fault tolerance rate of the identity identifier.
[0063] Among them, the error correction matrix can be set to Reed-Solomon code or Vandermonde matrix. The error correction matrix can improve the fault tolerance of the identity identification. For example, if some information base points in the display state are blocked or contaminated by foreign objects, it will cause the problem of incomplete identity identification. The error correction matrix can correct the identity identification and restore the partially damaged identity identification, thereby improving the fault tolerance of the identity identification.
[0064] S220: Generate an infrared image according to the infrared data through an image processing system.
[0065] S230 , performing image recognition on the infrared image through an information recognition system to determine information base points of each state in the infrared image as a display state.
[0066] S240: Determine the identity information of the target to be identified according to the arrangement of the information base points in the display state.
[0067] The technical solution of the embodiment of the present application is to scan the target to be identified through an infrared shooting system to obtain infrared data matching the target to be identified; generate an infrared image based on the infrared data through an image processing system; perform image recognition on the infrared image through an information recognition system to determine the information base points in each display state in the infrared image; and determine the identity information of the target to be identified based on the arrangement of the information base points in each display state. This technical solution provides a detailed introduction to the infrared recognition system, clarifies the components of the infrared recognition system, and introduces the working content of each component, making the implementation of this technical solution more specific.
