Firstly, the image is fed into the trained SegNet network model to obtain the segmented blind image, which is converted into a binary image to obtain the position information of the blind in the x-direction of the whole image, and then feature point extraction is performed in the blind area. Secondly, the polar line constraint is added to the feature matching part and the RANSAC algorithm is combined to optimize the matching to obtain the obstacle feature point pairs in the blind area. Finally, the parallax is calculated according to the two-dimensional planar structure of binocular stereo vision to find the precise distance of the obstacle. The experimental results show that the improved ORB algorithm has better real-time performance and accuracy.","PeriodicalId":129909,"journal":{"name":"2022 3rd International Conference on Geology, Mapping and Remote Sensing (ICGMRS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130831053","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Countries and many international institutions all over the world have been paying continuous attention to the problem of poverty eradication. Assessing the level of regional poverty is a key issue in formulating poverty eradication strategies. The luminous remote sensing data of LJ1-01 satellite is applied to the study of urban poverty rate. In the future, it will study and analyze poverty problems, solve the remaining poor groups, and it is envisaged to provide reliable support and help in dealing with new poverty problems in the future. Regard Tianjin as the study area, and the basic situation of urban poverty rate is verified with the corresponding statistical data. Through the experiment, imagine a poverty rate research based on urban blocks, combine the luminous remote sensing data with the urban social and economic development, grid the experimental area, and realize a more objective, accurate and persuasive poverty rate research, which is of great significance and application value to the urban poverty rate research, economic development and urban sustainable development. The final experimental results show that the quantitative value of luminous data can reflect the economic and demographic characteristics of Tianjin to a certain extent, and the best quantitative model used in this paper can reflect the spatial distribution of urban poverty rate in Tianjin to a certain extent.","PeriodicalId":129909,"journal":{"name":"2022 3rd International Conference on Geology, Mapping and Remote Sensing (ICGMRS)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132042036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Taking Guanshanhu District of Guiyang City in Guizhou Province as the research object, apply remote sensing images, ground monitoring and statistical data as data sources, with the help of variety of empirical models, this paper analyzes the change and sensitivity of ecosystem services in 2000, 2010 and 2020. The result shows that the area of forest and grassland ecosystem increased during 2000-2010 and decreased during 2010-2020. The human settlement ecosystem grew rapidly from 1146.82 hm2 to 7544.29 hm2 during 2000-2020. The farmland ecosystem continued to decrease from 13308.29 hm2 to 6342.33 hm2 during 2000-2020. With the dynamic changes of ecosystem spatial pattern and structure, the value of ecosystem services shows a steady growth trend because of the improving quality of ecosystem by implementing of various ecological engineering programs. The total value of forest and wetland ecosystems was sensitive and resilient to the ecosystem service value coefficient. In the future, it is necessary to establish a strict pre-trial system for the use of forest and wetland, so as to effectively protect forest and wetland resources and meet the growing ecological needs of residents.","PeriodicalId":129909,"journal":{"name":"2022 3rd International Conference on Geology, Mapping and Remote Sensing (ICGMRS)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130137828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Remote sensing inversion of chlorophyll-a concentration of Lake Tai in this paper was implemented, trying to use the measured data of Lake Tai and remote sensing images obtained from the HJ-1 satellite. Firstly, the acquired data was previously processed through atmospheric correction and radiometric calibration. Secondly, the sensitive factor was determined and the ways were band ratio, NDWI, NDVI about it. Thirdly, the inversion model was constructed, single band regression analysis was utilized and accuracy of the model was calculated. The result of the verification showed that the precision was remarkable.

However, space missions have strict restrictions on volume and weight. Therefore, light and compact design of space spectrometers are required. The aluminum mirror can undertake both optical and bearing functions, which is one of the key technologies to address this challenge and realize the light and compact optical-mechanical system that has broad applications. A novel structure design method for special-shaped lightweight aluminum mirror of space spectrometers is proposed in this study, which includes scheme design, assembly deformation and unloading structure mode analysis, and lightweight design method. The aluminum mirrors of a hyperspectral remote spectrometer is designed by this method to verify the effectiveness of the method. Different load-bearing structures and weight reduction designs are designed for different aluminum mirrors, so that the weight of this high complexity and multi temperature spectrometer is reduced by 50% while the accuracy remains unchanged.","PeriodicalId":129909,"journal":{"name":"2022 3rd International Conference on Geology, Mapping and Remote Sensing (ICGMRS)","volume":"285 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122103059","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Once a mountain fire occurs, it is easy to spread to the vicinity of the transmission corridor, resulting in the failure of transmission line tripping and reclosing. In order to effectively predict wildfires, this paper proposes a wildfire risk assessment model based on LightGBM. Combining vegetation factors, meteorological factors, terrain factors, and human factors, the moderately correlated fire point characteristics were screened out based on correlation analysis, and a wildfire risk assessment model was constructed. After that, the fire point products of NPP and MODIS are used as the validation data of the model, and the acracy of the model is predicted by the accuracy, precision, recall, F1-Score and AUC values.
