[0040] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0041] It is understood that although the functional modules are divided in the device schematic diagram and the logical order is shown in the flow chart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flow chart.

[0042] The spectral-polarization coupling property provides an important physical basis for high-dimensional information detection of target media, making the analysis and identification of target media more precise. At present, in the long-wave infrared band, it is widely used in environmental monitoring, resource exploration, target reconnaissance and other fields. How to achieve fast, efficient and real-time spectral polarization imaging has become an urgent problem to be solved.

[0043] Based on this, the embodiments of the present application provide a dynamic target imaging system, method, device and medium. By encoding the image plane once through the spatial coding component, the light flux can be increased and the signal-to-noise ratio can be improved. At the same time, the coding perception scheme itself has a data compression effect, which can effectively reduce the amount of data. Through the holographic wire grid polarizer installed on the rotating platform, polarization information of multiple angles can be obtained in the same time period, which can improve the recognition ability of the target in a complex background. In addition, the dynamic target imaging system of the present application can obtain multi-dimensional data such as space, spectrum, polarization, etc. of the target in one acquisition.

[0044] First, refer to Figure 1 , Figure 1 It is a schematic diagram of a dynamic target imaging system provided in an embodiment of the present application.

[0045] It can be understood that the dynamic target imaging system includes a front imaging lens group 100, a spatial encoding device 200, a collimating lens group 300, a dispersion device 400, a polarization device 500, an imaging detection device 600 and a controller, wherein the front imaging lens group 100, the spatial encoding device 200, the collimating lens group 300, the dispersion device 400, the polarization device 500 and the imaging detection device 600 are located on the same optical axis. The front imaging lens group 100 is used to receive and focus the light from the target area to form a primary image plane. The spatial encoding device 200 is used to encode the primary image plane. The collimating lens group 300 is used to collimate the light that has been spatially encoded so that it enters the subsequent dispersion device 400 and the polarization device 500 in the form of parallel light. The collimating lens group 300 ensures the stability and consistency of the light in subsequent processing. The dispersion device 400 uses the dispersion effect of light to separate light of different wavelengths. The polarization device 500 is used to perform polarization encoding on light, so that the imaging detection device 600 can obtain the spectral polarization information of the target area. The imaging detection device 600 and the controller can form an image based on the spectral polarization information.

[0046] It should be noted that the imaging detection device 600 is an infrared detection device, and the imaging detection device 600 includes an imaging lens group 610 and a detection device 620 .

[0047] It should be noted that the polarization device 500 includes a rotating platform and a holographic wire grid polarizer mounted on the rotating platform. The rotating platform can rotate at 0°, 45°, 90° and 135°. When the rotating platform rotates, the holographic wire grid polarizer will also rotate along with the rotation of the rotating platform, so that the imaging detection device 600 can obtain spectral polarization information at multiple angles, which can effectively improve the signal-to-noise ratio of the imaging. The rotation speed of the rotating platform can be adjusted according to the frame rate of the detector.

[0048] It should be noted that when imaging and detecting dynamic targets, since the target and the imaging system are in relative motion, the dynamic target imaging system of the present application does not need to adjust the encoding mode of the encoding device when imaging dynamic targets, but only needs to adopt a fixed encoding mode, thereby improving the imaging efficiency of the dynamic target imaging system.

[0049] Specifically, in some embodiments, the dynamic target imaging system is fixedly placed, and the front imaging lens group 100 faces the target area. When there is no dynamic target in the target area, the spectral polarization information will not change significantly. When a dynamic target appears in the target area, the current spectral polarization information will change significantly compared to the previous spectral polarization information. Therefore, it can be determined whether a dynamic target appears in the target area by judging the previous spectral polarization information and the current spectral polarization information.

[0050] It should be noted that by arranging the front imaging lens group 100, the spatial encoding device 200, the collimating lens group 300, the dispersion device 400, the polarization device 500 and the imaging detection device 600 on the same optical axis, it is possible to effectively avoid the phenomenon of light deflection and scattering during the propagation process, thereby improving the imaging quality. In addition, when all the devices are located on the same optical axis, it can be ensured that the propagation direction of the light is always consistent in the process of starting from the front imaging lens group 100, passing through each device in sequence, and finally reaching the imaging detection device 600, which can reduce the loss and deviation of the light during the propagation process, and improve the imaging quality and accuracy of the system.

[0051] It should be noted that the spatial coding device 200 is an optical template of a checkerboard metal film plated on a zinc selenide substrate, wherein the coding scheme of the spatial coding device 200 is 0, 1 random coding, and the unit size of the coding checkerboard of the spatial coding device 200 is the same as the pixel size of the imaging detection device 600. The coding scheme of 0, 1 random coding can improve the resolution of the imaging system and enhance the image features. In addition, since the unit size of the coding checkerboard is the same as the pixel size of the imaging detection device 600, each pixel can correspond to a unit of the checkerboard, thereby achieving accurate spatial coding, maintaining the integrity and accuracy of information during the imaging process, and avoiding image distortion or information loss that may be caused by size mismatch.

[0052] It should be noted that the dispersion device 400 is a zinc selenide-based isosceles prism, the top angle of the zinc selenide-based isosceles prism is 30 degrees, and the inclination angle of the zinc selenide-based isosceles prism is 50 degrees. By controlling the top angle of the zinc selenide-based isosceles prism to 30 degrees and the inclination angle of the zinc selenide-based isosceles prism to 50 degrees, the spectral resolution of the dynamic target imaging system can be effectively improved.

[0053] The holographic wire grid polarizer is a barium fluoride substrate holographic wire grid polarizer.

[0054] Second, refer to Figure 2 , Figure 2 is a flow chart of a dynamic target imaging method provided in an embodiment of the present application. The dynamic target imaging method can be applied to Figure 1The dynamic target imaging system shown in the figure, and the dynamic target imaging method include but are not limited to the following steps:

[0055] Step S100, when the target object enters a preset area, obtaining spectral polarization coupling data of a plurality of different polarization angles in the preset area;

[0056] Step S200, preprocessing a plurality of spectral polarization coupling data to obtain a plurality of spectral polarization images;

[0057] Step S300: Generate a motion trajectory map of the target object based on multiple spectral polarization images.

[0058] It is understandable that, since the dynamic target imaging system is fixedly placed, when a target object (an object in a moving state) appears in the preset area, the spectral polarization coupling data acquired by the imaging detection device 600 will be significantly different from the spectral polarization coupling data when no target object appears in the preset area, that is, it is possible to determine whether the target object appears in the preset area by judging the previous spectral polarization coupling data and the current spectral polarization coupling data. When the target object enters the preset area, the rotating platform will drive the holographic wire grid polarizer to rotate, and whenever the rotating platform rotates to 0°, 45°, 90° and 135°, the imaging detection device 600 acquires the spectral polarization coupling data, that is, the imaging detection device 600 repeatedly acquires the spectral polarization coupling data with polarization angles of 0°, 45°, 90° and 135°. 0°, 45°, 90° and 135° can just form two orthogonal angles, which can effectively improve the recognition of multiple spectral polarization images. By preprocessing multiple spectral polarization coupling data, the recognition of spectral polarization images can be improved, thereby improving the accuracy of generating the motion trajectory map of the target object.

[0059] It should be noted that the imaging detector 600 acquires the spectral polarization coupling data continuously, and the multiple spectral polarization images obtained by preprocessing the multiple spectral polarization coupling data are also continuous images. Therefore, the position and spectral polarization information of the target object can be extracted from the coded images captured by the multiple detectors, and the motion trajectory diagram of the target object can be generated. Figure 3 As shown, Figure 3It is a plurality of continuously acquired spectral polarization coupling data and encoded spectral polarization coupling images thereof provided in an embodiment of the present application. The plurality of encoded images include four continuous spectral polarization images A, B, C and D. Image A is taken as the base image, and then the position of the target object in the encoded images B, C and D and the corresponding encoding mode are extracted respectively, and then pasted into the corresponding positions in the encoded image A in sequence. Since the dynamic target imaging system is fixed, the backgrounds of the four images A, B, C and D are the same, that is, only the position of the target object changes in the captured original image. Therefore, after the position of the target object in the images B, C and D is pasted into the corresponding positions in the image A in sequence, the generated image is the spectral polarization image of the target object and its motion trajectory diagram.

[0060] Reference Figure 4 , Figure 4 yes Figure 2 The specific flow chart of step S200 includes but is not limited to the following steps:

[0061] Step S210, determining a target object portion and a background portion in each piece of spectral polarization coupling data according to a plurality of spectral polarization coupling data;

[0062] Step S220, preprocessing the target object portion in each spectral polarization coupling data to obtain a plurality of target processed data;

[0063] Step S230 , generating a plurality of spectral polarization images according to the plurality of target processing data and the background portion.

[0064] It can be understood that the spectral polarization coupling data is composed of the data of the target object part and the data of the background part. For dynamic target imaging, the clarity of the target object is the most important. Therefore, the target object part in each spectral polarization coupling data can be preprocessed to improve the imaging quality of the target object part. By preprocessing the target object part in each spectral polarization coupling data and reducing the processing of the background part, the amount of data can be effectively reduced, thereby improving the efficiency of data processing. Since the target object part is preprocessed, the target object part is imaged with high quality compared to the background part. Therefore, the enhanced detection of the target object can be achieved in the generated spectral polarization image through the preprocessed target processing data and the background part.

[0065] It should be noted that, since the dynamic target imaging system is fixed, that is, the backgrounds of the multiple spectral polarization images are the same, only the background part of the first spectral polarization coupling data among the multiple spectral polarization coupling data can be imaged. That is, in the process of generating multiple spectral polarization images according to the multiple target processing data and the background part, the spectral polarization coupling data of the background part in the multiple spectral polarization images can be the background part of the first spectral polarization coupling data.

[0066] Specifically, the multiple spectral polarization coupling data include first spectral polarization coupling data, second spectral polarization coupling data, third spectral polarization coupling data and fourth spectral polarization coupling data, the first spectral polarization coupling data include a first target part and a first background part, the second spectral polarization coupling data include a second target part and a second background part, the third spectral polarization coupling data include a third target part and a third background part, and the fourth spectral polarization coupling data include a fourth target part and a fourth background part, wherein the first target part, the second target part, the third target part and the fourth target part are preprocessed to obtain first target processing data, second target processing data, third target processing data and fourth target processing data, respectively. When imaging is performed according to the multiple target processing data and the background part, only the first background part can be used for imaging, that is, the first target processing data and the first background part generate a first spectral polarization image, the second target processing data and the first background part generate a second spectral polarization image, the third target processing data and the first background part generate a third spectral polarization image, and the fourth target processing data and the first background part generate a fourth spectral polarization image.

[0067] It should be noted that since the dynamic target imaging system is fixed and the coding array of the spatial coding device 200 is fixed, if there is no dynamic target in the preset area, the coding data obtained by the imaging detection device 600 is similar, that is, the coding of the static target is similar. Therefore, the target object part and the background part can be determined through the similar parts and dissimilar parts of multiple spectral polarization coupling data.

[0068] It should be noted that the preprocessing of the target object part in the spectrum polarization coupling data may be to reconstruct the target object part in each spectrum polarization coupling data by using a compressed sensing algorithm, wherein the compressed sensing algorithm may use a TwIST algorithm.
