Description

Technical Field

[0002] Optical components play a vital role in modern technology and are widely used in cameras, microscopes, telescopes, laser equipment, and various other optical instruments. Prisms and lenses are two basic optical components, each with unique functions and applications.

[0003] Applications and Functions of Prisms: Prisms can change the direction of light propagation, deflecting incident light through the principle of refraction. They are widely used in spectral analysis, imaging systems, and optical instruments, achieving functions such as dispersion, reflection, and light deflection. In cameras and projectors, prisms can be used to correct image direction, ensuring image accuracy and clarity.

[0004] Lens properties and applications: Lenses are primarily used to focus or diverge light, changing its focal length. Convex lenses focus light and are often used for magnification and imaging, while concave lenses diffuse light and are widely used in eyewear and optical instruments. The design and manufacturing precision of lenses is crucial to their optical performance, especially in high-end optical equipment, where even the slightest error can result in blurred or distorted images.

[0005] Defects of existing optical components: Currently, optical components on the market mainly rely on gluing two molded lenses and prisms together. During the assembly process, there is often a problem of loose docking between optical components, resulting in unstable optical paths and affecting optical performance.

[0006] Despite certain inspection methods during the production process, there is still a lack of real-time monitoring and analysis of the bonding effect of optical components, which can easily lead to fluctuations in product quality. In addition, traditional optical components are usually designed and manufactured independently, failing to fully utilize the combined advantages of prisms and lenses, resulting in increased complexity of the optical system and greater difficulty in assembly.

[0007] Demand for automation and intelligence: With the development of intelligent manufacturing and automation technology, higher requirements are placed on the production process of optical components. There is an urgent need for a new type of optical kit that can quickly and accurately achieve an effective combination of prisms and lenses so that the optical components of the kit have the optical properties of prisms and lenses.

[0088] Figure 1 The present invention provides a flowchart of a method for producing a prism lens combination optical kit. DETAILED DESCRIPTION

[0089] With the development of intelligent manufacturing and automation technology, higher requirements are being placed on the production process of optical components. There is an urgent need for a new type of optical kit that can quickly and accurately achieve the effective combination of prisms and lenses. This application introduces data acquisition and analysis technology to monitor the performance of optical components in real time, ensuring that each optical component meets the design standards, improving production efficiency and product reliability.

[0090] The present invention will be described in detail below with reference to the accompanying drawings.

[0091] Example 1

[0092] An embodiment of the present invention provides a prism lens combination optical kit, including a production and installation detection component, which includes a processor, a camera, and an optical path detection component.

[0093] Among them, the camera is used to capture a cross-sectional image of the contact surface between the prism lens combination optical element and the kit structure, and send the cross-sectional image to the processor. The optical path detection component is used to obtain optical path data when the prism lens combination optical element is installed on the card slot, and send the optical path data to the processor. The processor is used to determine whether the prism lens combination optical element is tightly glued to the card slot based on the cross-sectional image and the optical path data, and determine whether the prism lens effect of the optical kit meets the standards; if not, a prompt message is issued. In an embodiment of the present invention, the prompt message includes reinstalling the prism lens combination optical element or reproducing, adjusting the kit structure, and issuing information that the quality of the prism lens combination optical original does not meet the standards.

[0094] In an embodiment of the present invention, judging whether the prism-lens combination optical element is tightly glued to the card slot according to the cross-sectional image and the optical path data includes:

[0095] Preprocessing: Denoise and enhance the cross-sectional image to obtain a preprocessed image; clean the optical path data to obtain cleaned optical path data.

[0096] In an embodiment of the present invention, a high-resolution camera is used to capture a cross-sectional image of a prism-lens combination optical element, ensuring that the image is captured under good lighting conditions to obtain a clear image. A laser or other light source is used to measure the optical path data through the optical element, including the incident direction, exit direction, light intensity distribution, light intensity, and phase information.

[0097] During preprocessing, the acquired images undergo denoising and contrast enhancement to improve the accuracy of subsequent analysis. Denoising can be performed using methods such as mean filtering, median filtering, and Gaussian filtering. Enhancement can be performed using histogram equalization, brightness and contrast adjustment, Laplacian filtering, and high-pass filtering to enhance image edges and details.

[0098] Cleaning the optical path data: Recording the light intensity distribution in the contact area and measuring it using an optical sensor or camera. Data integration: Ensuring spatial alignment between the optical path data and the image data requires coordinate transformation or interpolation.

[0099] After preprocessing, the contact surface contour is extracted based on the preprocessed image. In this embodiment of the present invention, the contact surface contour can be extracted using a Canny operator. Alternatively, an edge detection algorithm can be used to extract the contour of the contact area in the processed image. Morphological operations (such as dilation and erosion) can be used to further clean the contour to obtain the final contact surface contour.

[0100] In order to improve the accuracy, reliability and convenience of judging whether the prism lens combination optical element is tightly glued to the card slot, the following method is used:

[0101] The contact area and contact uniformity index are obtained based on the contact surface profile and cleaning optical path data. The contact uniformity index is used to characterize the degree of contact uniformity between the prism lens assembly optical element and the card slot.

[0102] As a further illustration, the contact area and contact uniformity index are obtained based on the contact surface profile and cleaning optical path data, including:

[0103] A light path image is constructed based on the light path data, and the contact area between the prism lens assembly optical element and the card slot is extracted based on the light path image. Specifically, the light path image is constructed based on the light path data by using the light intensity of the light path data as the pixel value of the light path image and the light path illumination point as the coordinate point of the light path image.

[0104] The contact area is obtained based on the contact region. Specifically, the contact region can be detected using the Canny operator or the Huffman operator. The contact region is then binarized, with white representing the contact region and black representing the non-contact region. The contact area is obtained by multiplying the number of white pixels in the binary image by the area occupied by each pixel.

[0105] Light intensity information of the contact area is extracted from the cleaning optical path data to obtain a first-dimensional contact vector. The first-dimensional contact vector represents the contact between the mirror assembly optical element and the card slot in the first dimension, and the first-dimensional contact vector is represented by a light intensity distribution vector. Specifically, the light intensity of the cleaning optical path data is mapped to the contact area, and then feature extraction is performed on the contact area to obtain the first-dimensional contact vector. Feature extraction can be performed using a convolutional neural network or principal component analysis to extract features and obtain the first-dimensional contact vector. In this embodiment of the present invention, the first dimension is information in the coordinate axis X direction, or dimensional information of a plane passing through the X axis, and the second dimension is information in the coordinate axis Y direction, or dimensional information on a plane perpendicular to the plane of the first dimension and passing through the Y axis. That is, the first-dimensional contact vector is feature information observed in the X direction, that is, the front of the contact surface is observed, and the second-dimensional contact vector is feature information observed in the Y direction, that is, the cross-section of the contact surface is observed.

[0106] A second-dimensional contact vector is obtained based on the contact surface profile. The second-dimensional contact vector represents the contact between the optical element of the mirror assembly and the slot in the second dimension. Specifically, the second-dimensional contact vector is extracted from the contact surface profile to obtain the second-dimensional contact vector. A convolutional neural network can be used for feature extraction to obtain the second-dimensional contact vector.

[0107] Based on the combined analysis of the first dimension contact vector and the second dimension contact vector, the contact uniformity index is obtained. Specifically:

[0108] The first-dimensional contact vector and the second-dimensional contact vector are combined and analyzed using a multi-layer perceptron model, which then outputs a contact uniformity index. The multi-layer perceptron model comprises a first branch, a second branch, and an interaction layer. The first branch comprises multiple layers of sequentially connected first-branch hidden layers, and the second branch comprises multiple layers of sequentially connected second-branch hidden layers. The interaction layer is positioned between the corresponding first-branch hidden layers and the second-branch hidden layers, connecting them. The hidden layer is used to implement information exchange between the first-branch hidden layers and the second-branch hidden layers, thereby mining the implicit information associated with the first-dimensional contact vector and the second-dimensional contact vector.

[0109] In an embodiment of the present invention, a combined analysis is performed on the first-dimensional contact vector and the second-dimensional contact vector by using a joint multi-layer perceptron model, and the joint multi-layer perceptron model outputs a contact uniformity index, including:

[0110] Step S1: The first branch hidden layer of the i-th layer extracts features from the first input of the i-th layer to obtain the first feature H of the i-th layer A The second branch hidden layer of the i-th layer extracts features from the second input of the i-th layer and obtains the second feature H of the i-th layer. B i is a positive integer less than or equal to N, where N is the number of hidden layers. N is a positive integer greater than 3. When i = 1, the first input of the i-th layer is the first-dimensional contact vector; the second input of the i-th layer is the second-dimensional contact vector. That is, the first-dimensional contact vector is used as the input of the first-branch hidden layer of the first layer, and the second-dimensional contact vector is used as the input of the second-branch hidden layer of the second layer. The first-branch hidden layer and the first-branch hidden layer are used for feature extraction respectively.

[0111] Step S2: Feature mapping is performed in the following manner:

[0112] H′ A =f(W A H A +b A )

[0113] H′ B =f(W BH B +b B )

[0114] Among them, W A and W B are the first weight matrix learned by the first branch and the second weight matrix learned by the second branch respectively; b A and b B are the first bias term of the first branch and the second bias term of the second branch respectively; H′ A is the first mapping feature of the i-th layer, H′ B is the second mapping feature of the i-th layer, f() is the mapping function, which can be a ReLU function or a Swish function. f(W A H A +b A ) represents the mapping function for the input (W A H A +b A )’s mapping output, f(W B H B +b B ) represents the mapping function for the input (W B H B +b B )’s mapping output.

[0115] Step S3: After the interaction layer, the first mapping feature of the i-th layer and the second mapping feature of the i-th layer are combined using a fusion mechanism to obtain the i-th layer fusion feature H. The specific fusion method is shown in the following formula:

[0116] H=AH′ B +(1-A)H′ A

[0117] Where A is the attention weight matrix, which is obtained by training the joint multi-layer perceptron model; A = Represents H′ A The transposed matrix of , softmax() is the softmax function, Indicates that the softmax function is for input Output.

[0118] Step S4: Obtain the first feature H of the i-th layer A The first loss function of the i-th layer between the i-th layer fusion feature H, the i-th layer first loss function can be the i-th layer first feature H A Cross entropy between the fusion feature H of the i-th layer; obtain the second feature H of the i-th layer B The second loss function of the i-th layer between the i-th layer fusion feature H. The second loss function of the i-th layer can be the second feature H of the i-th layer BThe cross entropy between the fusion feature H of the i-th layer.

[0119] Step S5: Adjust the fusion feature H of the i-th layer based on the first loss function of the i-th layer to obtain the first branch adjustment feature of the i-th layer; adjust the fusion feature H of the i-th layer based on the second loss function of the i-th layer to obtain the second branch adjustment feature of the i-th layer.

[0120] Step S6: For the i+1th layer, the first branch adjustment feature of the i-th layer and the second branch adjustment feature of the i-th layer are used as the input of the first branch hidden layer of the i+1th layer and the second branch hidden layer of the i+1th layer, respectively, and the first branch adjustment feature of the i+1th layer and the second branch adjustment feature of the i+1th layer are obtained according to the method of steps S1 to S5.

[0121] The method shown in steps S1 to S6 is looped until i=N, and the last first branch hidden layer and the last second branch hidden layer respectively output the last first branch adjustment feature and the last second branch adjustment feature.

[0122] Step S7: Obtain a contact uniformity index based on the last layer first branch adjustment feature and the last layer second branch adjustment feature using the following formula.

[0123] Where U represents the contact uniformity index, σ(I A ) represents the standard deviation of the first branch adjustment feature of the next layer, I A Indicates the adjustment feature of the first branch of the next layer, μ(I A ) represents the mean of the adjusted features of the first branch of the next layer, ε represents an ultra-micro number, ε=0.001; σ(I B ) represents the standard deviation of the first branch adjustment feature of the next layer, I B Indicates the adjustment feature of the first branch of the next layer, μ(I B ) represents the mean of the adjusted features of the first branch of the next layer; λ and ξ represent the first weighting factor and the second weighting factor, respectively, and the first weighting factor and the second weighting factor are the eigenvalues ​​of the attention weight matrix, respectively.

[0124] By adopting the above scheme, the innovative joint multi-layer perceptron (MLP) model structure, through multiple input branches, feature fusion layers, and attention mechanisms, can effectively capture the complex correlations between them when processing two sets of data with different dimensions, directions, and meanings. This design not only improves the model's expressiveness, but also enhances its flexibility and interpretability. At the same time, by introducing an interaction layer and fusion mechanism, the first and second branches can effectively share and fuse each other's implicit information, thereby enhancing the model's ability to learn complex data relationships and can spread the implicit correlation between the first-dimensional contact vector and the second-dimensional contact vector. At the same time, the contact uniformity index obtained in this way can accurately, quickly, and effectively characterize the uniformity of the bonding between the mirror assembly optical element and the card slot, thereby improving the accuracy and reliability of judging whether the mirror assembly optical element and the card slot are tightly bonded.

[0125] In an embodiment of the present invention, if the eigenvalues ​​of the attention weight matrix are all 0 or there is no real eigenvalue, then λ=0 and ξ=1.

[0126] After obtaining the contact uniformity index, the tight bonding index is obtained based on the contact area and the contact uniformity index; the tight bonding index is used to characterize whether the prism lens combination optical element and the card slot are tightly bonded.

[0127] Optionally, obtaining a tight bonding index based on the contact area and the contact uniformity index includes:

[0128] Obtain the projected area of ​​the first-dimensional contact vector mapped onto the optical path image. Obtain a tight bonding index based on the contact uniformity index and the ratio K of the projected area to the contact area. Specifically, a weighted summation of the contact uniformity index and the ratio K of the projected area to the contact area is performed to obtain the tight bonding index, which is specifically obtained using the following formula:

[0129] D=ξλU+(1-λξ)K

[0130] Where D is the tight bonding index.

[0131] In this way, the obtained tight bonding index can accurately represent the bonding degree between the prism lens combination optical element and the card slot.

[0132] Furthermore, if the tight gluing index is less than a set value, it is determined that the prism lens combination optical element is not tightly glued to the card slot; if the tight gluing index is greater than or equal to the set value, it is determined that the prism lens combination optical element is tightly glued to the card slot. In an embodiment of the present invention, the set value is between 0.05 and 20.

[0133] By adopting the above solution, the accuracy and reliability of judging whether the mirror assembly optical element and the card slot are tightly glued can be improved.

[0140] S101: Capture a cross-sectional image of the contact surface between the prism lens combination optical element and the kit structure through a camera, send the cross-sectional image to a processor, obtain optical path data of the prism lens combination optical element when it is installed on the card slot through an optical path detection component, and send the optical path data to the processor.

[0142] In the embodiment of the present invention, the specific implementation process of step S102 is described above and will not be repeated here.

[0143] By adopting the above solution, the existing prism and lens optical assemblies have obvious deficiencies in functional integration, assembly accuracy, and quality control. To address these issues, the present invention proposes a prism-lens combination optical kit and its production method, aiming to improve the performance and stability of optical components by optimizing the design and production process.
