[0024] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described below with reference to the accompanying drawings and in combination with the embodiments.

[0025] In order to enable ordinary technicians in the field to better understand the technical solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all should belong to the protection scope of the present invention.

[0026] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are applicable to distinguishing similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable 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. In addition. The terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or are proprietary to these processes, methods, products or devices.

[0027] It should also be noted that the division of multiple embodiments in the present invention is only for the convenience of description and should not constitute a special limitation. The features in various embodiments can be combined and referenced to each other without contradiction.

[0028] like Figure 1As shown, the first embodiment of the present invention proposes a precision television design method based on computational optics, for example, including: step S1, constructing an initial structure including a zoom transmitting optical system and a precision television optical system coaxial with the zoom transmitting optical system, and performing selective aberration correction on the initial structure to obtain an intermediate optimization result; step S2, establishing a dynamic data exchange interface for obtaining a point spread function and an image to be restored of the initial structure according to the intermediate optimization result, and restoring the point spread function and the image to be restored by an image processing algorithm; step S3, using a preset evaluation function to evaluate the quality of the restored image; step S4, establishing a custom optimization operand for the initial structure, and returning the index value of the quality evaluation through the dynamic data exchange interface to update the custom optimization operand; step S5, obtaining the optimal optical structure and the best imaging effect of the joint design through iterative optimization until the custom optimization operand takes the minimum value.

[0029] Specifically, in step S1, for example, the optical simulation software ZEMAX is used to build an initial structure including a zoom transmission optical system and a precision optical system. Figure 2 As shown, the transmission-type high-intensity laser emission optical system and the precision television optical system are coaxial, and are mainly used to realize the zoom emission of high-energy lasers and focus the laser at a specified distance to damage the target.

[0030] Specifically, the system consists of a laser collimation optical system 1, a dichroic mirror 2, a fast mirror 3, a zoom emission optical system 4 and a precision television optical system 5. The laser collimation optical system 1 collimates the laser with a main wavelength of 1080nm and a power greater than 2000W into a 15mm spot, which is reflected by the dichroic mirror 2 and the fast mirror 3 and enters the zoom emission optical system 4. The zoom emission optical path focuses the high-energy laser at different distances to damage the target through the secondary mirror. Visible light or active illumination laser enters the precision television optical system 5 through the zoom emission optical system 4, the fast mirror 3 and the dichroic mirror 2 to achieve the capture and tracking of the target.

[0031] Furthermore, the initial structure is selectively corrected for aberration by inputting numerical values ​​in the optical simulation software or by manual mechanical adjustment, so that the spherical aberration of the initial structure is significantly improved, and an intermediate optimization result is obtained.

[0032] Combination Figure 3As shown, in step S2, for example, a dynamic data exchange interface between the image processing software Microsoft Visual Studio and the optical simulation software ZEMAX is established, and Microsoft Visual Studio, as a client program, obtains the PSF (point spread function) of the optical system and the image to be restored from ZEMAX. For example, a spatially varying cross-channel image algorithm is selected as the restoration image processing algorithm, and the PSF of the optical system and the image to be restored are preprocessed and analyzed by Matlab, and restored using the cross-channel image algorithm.

[0033] It is worth mentioning that the selected image processing algorithm can be a common image processing algorithm such as the Wiener filtering algorithm, the Richardson-Lucy algorithm, the super Laplace prior non-blind deconvolution algorithm, the contrast enhancement algorithm based on block overlap, the spatially varying cross-channel image restoration algorithm, and the cross-channel prior deconvolution algorithm. It can also be an algorithm written from the perspective of optical geometric aberration correction to more specifically correct the aberrations that are difficult to correct in the current optical system. This embodiment is not limited to this.

[0034] In step S3, for example, the blind image space quality evaluation method (BRISQUE) is selected as an evaluation function to evaluate the quality of the restored image. Specifically, the selected evaluation function can be contrast evaluation, signal-to-noise ratio evaluation, contrast loss and signal-to-noise ratio combined evaluation, clarity evaluation, edge preservation coefficient evaluation, etc. For an optical system with an imaging target prior model, pixel error, structural similarity, recognition accuracy, bit error rate, etc. can also be used as an evaluation function. The blind / no-reference image space quality evaluation method and the natural image quality evaluation method can be used to quantitatively evaluate the image quality.

[0035] Furthermore, for example, image quality characteristics are extracted based on statistical characteristics of local normalized brightness of the image, and then a support vector machine is used to learn the image characteristics and subjective image scores, thereby predicting the score of the evaluated image.

[0036] In step S4, for example, a UDOP user-defined optimization operand is established in the optical simulation software ZEMAX, and the index value of the quality evaluation is returned to the optical simulation software ZEMAX through a dynamic data exchange interface to update the user-defined optimization operand UDOP.

[0037] In step S5, the user-defined optimization operand UDOP is iteratively optimized until UDOP reaches a minimum value. Finally, the optimal optical structure and the best imaging effect of the joint design are obtained. Specifically, the damped least square method is used to iteratively optimize the user-defined optimization operand, and the optimal optical structure for clear imaging in the precision television optical system is obtained according to the minimum value of the user-defined optimization operand.

[0038] Furthermore, the point spread function is corrected according to the optimal optical structure and the image formed in the precision optical system so that the image achieves the best imaging effect. Specifically, the spatially varying PSF can be measured and combined with the Seidel aberration model to establish a spatially varying PSF parameter model, and the measured spatially varying PSF can be fitted to reconstruct the PSF of each field of view of the system, so that the jointly designed optical system achieves the best effect.

[0039] like Figure 4 As shown, the second embodiment of the present invention further proposes a precision television design device based on computational optics, including: an initial structure building module 201, an image restoration module 202, an image quality evaluation module 203, an optimization operation number module 204 and an optimization design module 205.

[0041] In one embodiment, the image quality assessment module 203 is specifically used to: extract the image quality characteristics of the precision television optical system according to the statistical characteristics of the local normalized brightness of the image, use a support vector machine to learn the image quality characteristics and the subjective score of the image, so as to predict the score of the evaluated image.

[0042] In one embodiment, the optimization design module 205 is specifically used to: use the damped least squares method to iteratively optimize the custom optimization operand until the custom optimization operand reaches a minimum value, and obtain the optimal optical structure for clear imaging in the precision television optical system based on the minimum value of the custom optimization operand.

The laser collimation optical system 1 collimates the laser with a main wavelength of 1080nm and a power greater than 2000W into a 15mm spot, which is reflected by the dichroic mirror 2 and the fast mirror 3 and enters the zoom emission optical system 4. The zoom emission optical path focuses the high-energy laser at different distances to damage the target through the secondary mirror. Visible light or active illumination laser enters the precision television optical system 5 through the zoom emission optical system 4, the fast mirror 3 and the dichroic mirror 2 to achieve the capture and tracking of the target.
