Research on automatic identification algorithm of invoice information 发票信息自动识别算法研究
Liangyu Jiao, Hui Li
The invoice reimbursement process is very cumbersome and requires manual entry of key information in the invoice, which wastes a lot of manpower and time. Therefore, it is particularly important to design an algorithm for intelligent identification of invoice information. Traditional algorithms can identify information from scanned invoice images. However, since in our country, most of the invoice information is Chinese characters, the current recognition algorithm has a certain degree of difficulty in identifying Chinese characters, and garbled characters will appear. Therefore, this article combines the CTPN text detection algorithm with the DesNets text recognition algorithm, and uses this algorithm to detect and recognize text on the information extracted from the invoice area image. Experiments show that the model outperforms the comparison model, with a recognition accuracy of up to 99.79%.
发票报销流程非常繁琐,需要人工录入发票中的关键信息,浪费了大量的人力和时间。因此,设计一种智能识别发票信息的算法尤为重要。传统算法可以从扫描的发票图像中识别信息。但由于在我国,大部分发票信息都是汉字,目前的识别算法在识别汉字时存在一定难度,会出现乱码。因此,本文将 CTPN 文本检测算法与 DesNets 文本识别算法相结合,利用该算法对从发票区域图像中提取的信息进行文本检测和识别。实验表明,该模型优于对比模型,识别准确率高达 99.79%。

A music generation model based on Bi-LSTM 基于 Bi-LSTM 的音乐生成模型
yong bai
The unidirectional LSTM based music generation model does not take into account the influence of future information when generating music. It solely focuses on learning the dependencies of the current moment on past information, resulting in music with poor stability and subpar quality. To address this issue, we have developed a music generation model based on bidirectional LSTM. During the training phase, this model effectively captures musical information from both past and future time steps, resulting in a probability distribution of musical elements that closely approximates real-world music. This, in turn, leads to enhanced structural stability and improved music quality in the generated compositions. Finally, we conducted validation experiments on our proposed approach, and the results unequivocally demonstrate its effectiveness.
基于单向 LSTM 的音乐生成模型在生成音乐时没有考虑未来信息的影响。它只专注于学习当前时刻对过去信息的依赖性,导致音乐稳定性差、质量不高。针对这一问题,我们开发了一种基于双向 LSTM 的音乐生成模型。在训练阶段,该模型能有效捕捉来自过去和未来时间步骤的音乐信息,从而产生与真实世界音乐非常接近的音乐元素概率分布。这反过来又增强了生成作品的结构稳定性,提高了音乐质量。最后,我们对所提出的方法进行了验证实验,结果明确证明了该方法的有效性。

Bin Huang
The three-dimensional laser scanning technology is a non-contact measurement of objects by using a three-dimensional scanner. It is a new surveying and mapping technology, also known as real-life replication technology. This technology can completely reconstruct the surface of the scanned object through the 360-degree rotation of the laser emitter. The accuracy of point cloud data is very high. Each three-dimensional data in the laser point cloud is the real three-dimensional data X, Y, and Z coordinates of the building target, which makes the post-processing data true and reliable, and its accuracy reaches 3mm ~ 6mm. The working principle of this technology is through reverse three-dimensional data acquisition and model reconstruction, on-site photography, texture mapping for the later period, can truly achieve 1 : 1 physical restoration, and then quickly reconstruct the three-dimensional model of the building, so as to obtain the building point, line, surface, body and other mapping data.

Lei Yin, Jian Wu, Qikong Liu, Wenxiong Wu
In order to improve the accuracy and real-time performance of cotton top bud recognition, an improved YOLOv5s target real-time detection model is proposed. First, the SE module and the CBAM module in the attention mechanism are added to optimize the weight ratio of channel attention and spatial attention to improve accuracy; then the BiFPN structure of bidirectional weighted features is introduced to strengthen the fusion between high-level features and low-level features; finally, a new bounding box regression loss function EIoU is used for ablation experiments, and more position information of cotton buds can be obtained by reducing the bounding box loss. The experimental results show that, by applying the improved algorithm in the identification of cotton top buds, compared with the original YOLOv5s model, the accuracy of the C3SE-4l+BiFPN+EIoU model has increased by 7.9%, the recall rate has increased by 2.8%, and the average precision an increase of 5.7%. These improvements and optimizations provide a new idea and method, which can provide a more efficient solution for the identification of cotton top buds.

Moisture detection of oil-immersed bushing insulation based on color level analysis 基于色度分析的油浸套管绝缘层湿度检测
Hongmin Ren, Denan Wang, Danni Duan
The operational level and service life of oil-immersed bushings are related to the moisture content in their cellulosic insulation layers. The authors proposed a novel method based on Taylor series modeling and grey relational analysis to assess the moisture content in the cellulosic insulation of oil-immersed bushings. Unlike conventional methods relying solely on frequency domain spectroscopy (FDS) data from certain frequency ranges, this method uses Taylor series to model the full spectrum and extracts a set of moisture-related feature parameters, thus avoiding dependence on specific measurement points or ranges. To establish the relationship between feature parameters and moisture levels, a database was constructed in this study. Grey relational analysis was used to propose an alternative method for assessing the moisture in bushing cellulosic insulation. Results show the average relative error between the estimated and measured moisture was less than 15.7%. Overall, the proposed method in this study provides an effective approach for assessing the moisture in the cellulosic insulation of oil-immersed bushings.
油浸式衬套的运行水平和使用寿命与其纤维素绝缘层中的含水量有关。作者提出了一种基于泰勒级数建模和灰色关系分析的新方法,用于评估油浸式衬套纤维素绝缘层中的含水量。与仅依赖特定频率范围的频域光谱 (FDS) 数据的传统方法不同,该方法使用泰勒级数对整个光谱进行建模,并提取一组与湿度相关的特征参数,从而避免了对特定测量点或测量范围的依赖。为了确定特征参数与湿度之间的关系,本研究建立了一个数据库。通过灰色关系分析,提出了一种评估衬套纤维素绝缘材料湿度的替代方法。结果表明,估计湿度和测量湿度之间的平均相对误差小于 15.7%。总之,本研究中提出的方法为评估油浸式衬套纤维素绝缘层中的水分提供了一种有效的方法。

Research on obstacle distance measurement method of UAV based on image processing technology 基于图像处理技术的无人机障碍物距离测量方法研究
mingxia Lin
In order to understand the obstacle distance measurement method of UAV, a research on obstacle distance measurement method of UAV based on image processing technology is proposed. This paper proposes an obstacle detection algorithm based on edge extraction. The outline of the obstacle can be obtained by extracting the edge features in the image, and the size, shape and position of the obstacle can be obtained by using a rectangle to frame the outline. Then the distance of the obstacle can be extracted from the contour of the obstacle by using the depth map generated by the binocular camera. The millimeter wave radar in front is used to fuse ranging with the central area of binocular camera image to improve the update frequency of obstacle distance. Finally, the effectiveness of the obstacle avoidance control strategy is verified by the obstacle avoidance flight test, and the UAV can choose the optimal obstacle avoidance direction and successfully bypass when encountering obstacles. The comparison of obstacle avoidance results shows that the obstacle avoidance method in this paper is advanced and has certain engineering application value.
为了了解无人机的障碍物测距方法,提出了基于图像处理技术的无人机障碍物测距方法研究。本文提出了一种基于边缘提取的障碍物检测算法。通过提取图像中的边缘特征可以得到障碍物的轮廓,用矩形框框出轮廓可以得到障碍物的大小、形状和位置。然后利用双目摄像头生成的深度图,从障碍物轮廓中提取障碍物的距离。利用前方的毫米波雷达与双目摄像头图像的中心区域进行融合测距,以提高障碍物距离的更新频率。最后,通过避障飞行试验验证了避障控制策略的有效性,无人机在遇到障碍物时能够选择最优避障方向并成功绕过。避障结果对比表明,本文的避障方法是先进的,具有一定的工程应用价值。

This paper proposes an obstacle detection algorithm based on edge extraction. The outline of the obstacle can be obtained by extracting the edge features in the image, and the size, shape and position of the obstacle can be obtained by using a rectangle to frame the outline. Then the distance of the obstacle can be extracted from the contour of the obstacle by using the depth map generated by the binocular camera. The millimeter wave radar in front is used to fuse ranging with the central area of binocular camera image to improve the update frequency of obstacle distance. Finally, the effectiveness of the obstacle avoidance control strategy is verified by the obstacle avoidance flight test, and the UAV can choose the optimal obstacle avoidance direction and successfully bypass when encountering obstacles.
