Description

Technical Field

[0001] The present invention relates to the field of computer vision technology, and in particular to a method and system for space station in-station device interaction based on scene semantic segmentation. Background Art

[0002] The confined and confined space of the space station necessitates that internal air circulation rely on a ventilation system. Astronauts' breathing, sweat, and moisture generated by equipment operation make the station's equipment susceptible to oxidation and mold, seriously threatening its performance and service life, impacting the station's safe and stable operation, as well as the astronauts' health and work efficiency. To ensure the station's long-term and reliable operation, astronauts must regularly maintain the equipment. New ways for space station equipment to interact are currently a hot topic of research. Early equipment detection methods relied on traditional image processing methods, typically employing computer vision and image processing techniques such as edge detection, color segmentation, and shape matching.

[0003] In recent years, deep learning technology has made significant progress in device recognition. Deep learning models can learn complex feature representations from large amounts of data, improving the accuracy and robustness of device recognition. We use the DeepLabV3+ network to perform semantic segmentation of target devices, employ the Visual Background Extractor (ViBe) combined with grayscale histograms for double Gaussian fitting, and implement object detection using the RetinaNet network.

[0004] As a classic semantic segmentation network, DeepLabV3+ has achieved remarkable results in complex scene segmentation tasks by introducing a dilated spatial pyramid pooling module and an encoder-decoder structure. However, some limitations remain. The original DeepLabV3+ network has limited ability to integrate contextual information from multi-scale features, and is particularly prone to information loss when recovering edge details and segmenting small objects. Backbone networks based on the Xception neural network architecture or the Residual Neural Network (ResNet) architecture have large parameter counts, making them difficult to deploy on mobile devices or resource-constrained devices. The traditional dilated convolution of Atrous Spatial Pyramid Pooling (ASPP) uses discrete interval sampling, resulting in less dense receptive field coverage and difficulty capturing continuous multi-scale context. The importance of feature channels and spatial positions is not dynamically weighted, making it susceptible to background noise in complex scenes.

[0005] In the existing technology, there is a lack of an accurate and efficient method for device interaction within a space station based on scene semantic segmentation. Summary of the Invention

[0029] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0030] The embodiment of the present invention provides a method for space station in-station device interaction based on scene semantic segmentation, which can be implemented by a space station in-station device interaction device, which can be a terminal or a server. Figure 1 The flowchart of the method for interacting with devices in a space station based on scene semantic segmentation is shown. The processing flow of the method may include the following steps:

[0031] S1. Collect images of equipment in the space station and obtain training data.

[0032] In one feasible implementation, the present invention collects a large number of images of instruments and components within the space station and annotates each component with a semantic label. Labeling tools such as Labelme are used to generate the annotated data in common formats such as Pascal VOC. Basic image operations are performed using image processing libraries such as the Open Source Computer Vision Library (OpenCV). The collected images are then preprocessed, including cropping, scaling, and denoising, to improve image quality. The training data images have a resolution of 3840×2160.

[0033] S2. Build a semantic segmentation model for the image to be trained based on the model structure of the DeepLabv3+ network.

[0034] In one feasible implementation, a deep learning model for semantic segmentation (DeepLab Version 3Plus, DeeplabV3+) introduces a new encoder-decoder architecture. The encoder consists of a deep convolutional neural network (DCNN) with dilated convolutions, which can be used with a common classification network. At the end of the encoder, DeeplabV3+ introduces an atrous spatial pyramid pooling (ASPP) module with dilated convolutions to achieve multi-scale object segmentation capabilities.

[0035] ASPP performs 1x1 convolutions on the input feature maps, followed by 3x3 convolutions with dilation rates of 6, 12, and 18, and global average pooling. It then fuses the feature maps and performs 1x1 convolutions to reduce the number of channels to 256. ASPP can extract and distinguish feature information from objects of different scales, effectively achieving multi-scale object segmentation. This module aims to capture contextual information at different scales to better understand the semantics of an image.

[0036] Compared with DeepLabv3, DeepLabv3+ introduces a Decoder module, which performs necessary downsampling operations on the input image, further fuses the underlying features with the high-level features, fuses the low-level features in the feature map recovery process, and restores the boundary information of the target part. The feature map recovery uses a linear interpolation method, which ultimately improves the accuracy of network segmentation.

[0037] S3. Based on the image segmentation loss function, the training data is used to train the image semantic segmentation model to obtain the image semantic segmentation model.

[0038] Among them, the image semantic segmentation model includes an encoder part and a decoder part;

[0039] The backbone network of the encoder part is the lightweight convolutional neural network MobileNetV2;

[0040] The multi-scale feature extraction module of the encoder part is the DenseASPP module of dense void spatial pyramid pooling;

[0041] The image semantic segmentation model adopts the CBAM module that combines the channel attention mechanism and the spatial attention mechanism.

[0042] One possible implementation uses the Xception network as the backbone of the classic DeeplabV3+ network. The Xception model has a relatively complex architecture and powerful expressive capabilities, making it suitable for complex tasks and large datasets. However, due to its relatively large model size, it requires more computing resources and storage space, and training time is generally longer, making it less suitable for resource-constrained devices.

[0043] Therefore, the classic DeeplabV3+ network architecture was improved, with the backbone network replaced with the lightweight convolutional neural network MobileNetV2. Compared to the Xception network, MobileNetV2 has a lower model size and computational complexity, making it suitable for mobile devices and embedded systems. Due to its lightweight design, MobileNetV2 also boasts faster inference performance.

[0044] MobileNet primarily replaces ordinary convolution with depthwise convolution and introduces two hyperparameters, the width factor and the resolution factor, to flexibly control the size of the network model. By optimizing the network structure, the network accuracy exceeds that of most neural networks with fewer parameters and computational complexity.

[0045] MobileNetv2 adds two key modules to its architecture: a linear bottleneck relationship between network layers and residual connections between bottleneck blocks. The bottleneck block design effectively encodes feature information at both the input and output ends of the model. The inner layers of the network encapsulate information from lower-level layers (such as object edges and outlines) into higher-level, abstract representations.

[0046] MobileNetv2 adds point convolution before depth-wise separable convolution, which allows for free adjustment of channels. The activation function can effectively increase the nonlinear representation of the network model in high-dimensional space, but will destroy features in low-dimensional feature space. This is the design of the inverted residual module. The input first undergoes 1x1 convolution for channel expansion, then uses 3x3 depth-wise convolution, and finally uses 1x1 point convolution to compress the channel to a low dimension. The whole process is "expansion-convolution-compression".

[0047] The Convolutional Block Attention Module (CBAM) is a widely used attention mechanism in deep learning. Its purpose is to improve model performance by focusing on important parts of an image. CBAM processes both the channel and spatial dimensions. First, the channel attention module focuses on "which channels are important," and then the spatial attention module focuses on "where" the informative parts are. This dual attention mechanism enables CBAM to fully capture key information in features.

[0048] Traditional atrous spatial pyramid pooling (ASPP) uses parallel atrous convolutions and atrous convolutions with different dilation rates for feature extraction. It can capture multi-scale information through convolutions with different receptive fields.

[0049] However, as the dilation rate increases (especially when it exceeds 24), the effective weight of the dilated convolution decreases, and the feature extraction capability also decreases. Therefore, this paper replaces the traditional ASPP module with the Densely Connected Atrous Spatial Pyramid Pooling (DenseASPP) module. DenseASPP can better capture the semantic information in the image.

[0050] Among them, the image segmentation loss function is obtained by weighted calculation of multiple image semantic category loss functions; the category loss function is the cross entropy loss function.

[0051] In one feasible implementation, the present invention divides the training dataset into training, validation, and test sets to ensure model generalization. Model hyperparameters (such as learning rate and batch size) are adjusted, and transfer learning techniques are used to improve training efficiency. Training is performed on an Nvidia Jetson Xavier NX development board, with loss and accuracy monitored during training, and the optimal model saved.

[0052] During training, for each pixel in the image, the cross-entropy loss is calculated between the predicted category and the true category. Cross-entropy loss is commonly used in classification problems and is particularly applicable to per-pixel classification tasks in image semantic segmentation. To address class imbalance, different weights are assigned to different categories. By assigning weights to different categories, the loss contribution of each category is balanced, preventing some categories from having a disproportionate impact on the overall loss.

[0053] S4. Obtain a device image of the current scene; input the device image of the current scene into an image semantic segmentation model to obtain a device segmentation image.

[0054] Optionally, the current scene device image is input into an image semantic segmentation model to obtain a device segmentation image, including:

[0055] Preprocess the current scene device image to obtain a processed device image;

[0056] Based on the processed device image, preliminary feature extraction is performed through the backbone network to obtain the first feature map;

[0057] According to the first feature map, the CBAM module is used to perform feature enhancement to obtain a third feature map;

[0058] The third feature map is input into the DenseASPP module for multi-scale feature extraction to obtain a multi-scale dense feature map;

[0059] Based on the first feature map, resolution recovery is performed according to the multi-scale dense feature map to obtain a device segmentation image.

[0060] In one feasible implementation, after the camera captures the image, it is transmitted to the electronic device for processing in real time. A pre-processing module is used to perform operations such as cropping, scaling, and denoising on the image to improve image quality.

[0061] DenseASPP adopts a densely connected and cascaded dilated convolutional layer design. The output of each dilated convolutional layer is not only passed to the next layer, but also connected to all subsequent unvisited layers, forming a dense feature transfer path. The expansion rate of each layer of DenseASPP increases layer by layer, and the final output is a multi-expansion rate, multi-scale dense feature map as shown in formula (1):

[0062] (1);

[0063] in, represents the expansion rate of the lth layer; () represents dilated convolution; Represents a feature map formed by concatenating the outputs of all previous layers. DenseASPP not only gradually accumulates multi-scale features through dense connections, but also the receptive field is determined by multiple consecutive atrous convolutional layers, avoiding the performance degradation caused by a single high dilation rate.

[0064] In the decoder, high-level features are fused with low-level features. The low-level features, derived from the first feature map, contain more spatial detail, helping to restore spatial details in the image. The feature map is upsampled to the original image resolution using bilinear interpolation or deconvolution to generate the final segmentation result. Upsampling gradually restores the image resolution, resulting in more refined segmentation results.

[0065] Optionally, according to the first feature map, using a CBAM module to perform feature enhancement to obtain a third feature map includes:

[0066] Based on the multi-layer perceptron, channel attention calculation is performed according to the first feature map to obtain a channel attention map;

[0067] Based on the channel attention map, the channel feature of the first feature map is enhanced to obtain the second feature map;

[0068] Based on the 7×7 convolutional layer, spatial attention calculation is performed according to the second feature map to obtain the spatial attention map;

[0069] Based on the channel attention map and the spatial attention map, feature enhancement is performed according to the first feature map to obtain a third feature map.

[0070] In one feasible implementation, channel attention obtains two different feature descriptions (one average and one maximum) for each channel of the input feature map through global average pooling and global maximum pooling. These two descriptions are processed by a multi-layer perceptron with shared weights, and the output feature map is then element-wise summed, and a sigmoid function is applied to generate a channel attention map M. c , the shape is consistent with the number of input channels. The formula is as follows (2):

[0071] (2);

[0072] Among them, MLP is a multi-layer perceptron; AvgPool represents average pooling; MaxPool represents maximum pooling; F is the first feature map; σ represents the Sigmoid activation function.

[0073] The feature map after spatial attention is applied to the channel attention is used to generate two two-dimensional feature maps through average pooling and maximum pooling in the channel direction. These two feature maps are stacked in the channel dimension, passed through a 7×7 convolution layer, and the sigmoid function is used to generate the spatial attention map M. s The formula is as follows (3):

[0074] (3);

[0075] Among them, Conv represents convolution operation; Concat represents concatenation operation.

[0076] The third feature map is obtained by combining the first feature map F with the channel attention map and the spatial attention map by element-wise multiplication. The process is as follows (4):

[0077] (4);

[0078] Through such a structure, CBAM can effectively enhance the network's response to important features in the image, improve the model's performance in various visual tasks, especially in image recognition and segmentation of complex scenes.

[0079] S5. Obtain interaction requirements: Based on the space station equipment database, according to the interaction requirements and the equipment segmentation image, retrieve the space station equipment information in the UI interface.

[0080] Optionally, based on the space station device database, according to interaction requirements and device segmentation images, the space station device information is retrieved in the UI interface, including:

[0081] Extract information based on the device segmentation image to obtain device image information;

[0082] Based on the space station equipment database, data query is performed according to the equipment image information to obtain detailed equipment information;

[0083] Based on interaction needs, space station device information is retrieved through the UI interface according to device image information and device detailed information.

[0084] In a feasible implementation manner, the present invention calls preset device images in a space station device database based on the device segmentation image to generate device detailed information with labeled images.

[0085] The annotated image is displayed on the UI, and you can tap an area of interest to view detailed information. Manually tapping an annotated area on the touchscreen will bring up a 3D model of the component in that area and related information. Learn about the component's name, function, and operation instructions through the 3D model and text description.

[0086] The interactive UI used in this paper is developed based on the Tkinter UI framework and supports interactive functions such as exploded view operation, zooming in, zooming out, and rotating the 3D models of the space station equipment. The paper creates a 3D model for each industrial instrument and its parts, using SketchUp software to design and export the 3D model files.

[0087] This paper proposes a method for in-station device interaction in a space station based on scene semantic segmentation. It introduces a channel-spatial dual attention module into the encoder portion of the DeepLabV3+ network to improve the model's robustness to complex scenes. It also replaces the original backbone network, Xception, with MobileNetV2, leveraging its inverted residual structure and linear bottleneck layer to reduce the number of parameters and computational complexity.
