The factors affecting the surface displacement monitoring of the slope are analyzed mainly from system structure parameters and environment parameters. Based on the error analysis theory, the functional relationship between the structure parameters and the monitoring error is studied. The error distribution curve is obtained through laboratory testing and sensitivity analysis, and parameter selection criteria are proposed. Corresponding image optimization methods are designed according to the error distribution curve of the environment parameters, and a large number of tests proved that the methods effectively improved the measurement accuracy of slope deformation monitoring. Finally, the reliability and accuracy of the proposed system and method are verified by displacement measurement of a slope on site.<\/jats:p>","DOI":"10.3390\/s20071994","type":"journal-article","created":{"date-parts":[[2020,4,2]],"date-time":"2020-04-02T11:57:14Z","timestamp":1585828634000},"page":"1994","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Accuracy Improvement of Binocular Vision Measurement System for Slope Deformation Monitoring"],"prefix":"10.3390","volume":"20","author":[{"given":"Qijun","family":"Hu","sequence":"first","affiliation":[{"name":"School of Civil Engineering and Geomatics, Southwest Petroleum University, Chengdu 610500, China"}]},{"given":"Ziyuan","family":"Feng","sequence":"additional","affiliation":[{"name":"School of Civil Engineering and Geomatics, Southwest Petroleum University, Chengdu 610500, China"}]},{"given":"Leping","family":"He","sequence":"additional","affiliation":[{"name":"School of Civil Engineering and Geomatics, Southwest Petroleum University, Chengdu 610500, China"}]},{"given":"Zihe","family":"Shou","sequence":"additional","affiliation":[{"name":"Sichuan Tibetan Area Expressway Co., Ltd., Chengdu 610041, China"}]},{"given":"Junsen","family":"Zeng","sequence":"additional","affiliation":[{"name":"School of Mechatronic Engineering, Southwest Petroleum University, Chengdu 610500, China"}]},{"given":"Jie","family":"Tan","sequence":"additional","affiliation":[{"name":"School of Civil Engineering and Geomatics, Southwest Petroleum University, Chengdu 610500, China"}]},{"given":"Yu","family":"Bai","sequence":"additional","affiliation":[{"name":"School of Civil Engineering and Geomatics, Southwest Petroleum University, Chengdu 610500, China"}]},{"given":"Qijie","family":"Cai","sequence":"additional","affiliation":[{"name":"School of Transportation and Logistics, Southwest Jiaotong University, Chengdu 610031, China"}]},{"given":"Yucheng","family":"Gu","sequence":"additional","affiliation":[{"name":"School of Civil Engineering and Geomatics, Southwest Petroleum University, Chengdu 610500, China"}]}],"member":"1968","published-online":{"date-parts":[[2020,4,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"425","DOI":"10.1007\/s10346-013-0391-7","article-title":"Landslide susceptibility mapping using GIS-based multi-criteria decision analysis, support vector machines, and logistic regression","volume":"11","author":"Kavzoglu","year":"2013","journal-title":"Landslides"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1045","DOI":"10.3390\/rs5031045","article-title":"Persistent Scatterer Interferometry (PSI) Technique for Landslide Characterization and Monitoring","volume":"5","author":"Tofani","year":"2014","journal-title":"Remote Sens."},{"key":"ref_3","doi-asserted-by":"crossref","unstructured":"Marek, L., Mi\u0159ijovsk\u00fd, J., and Tu\u010dek, P.
