Study On Binocular Range Measure Ment In Information Collection Of Paddy Field Culture Area

With the advent of the artificial intelligence era,a variety of intelligent facilities have gradually entered people's lives,and land measurement technology has also achieved intelligence.This paper discusses the use of binocular depth camera to reconstruct the rice field image by three-dimensional reconstruction of the rice field image.A new method,using binocular camera to collect rice field images,using OpenCV as an algorithm support,using C/C++ programming language for programming,obtaining 3D point cloud coordinates,and using meshlab to convert to visual 3D perspective,can basically realize rice paddy area Ranging,the main research contents and results are as follows:1.In-depth understanding of the development prospects and significance of paddy field aquaculture,research on the ratio of planting and planting in rice fields,summarizing the patterns of several comprehensive cultivation of rice fields,and analyzing the importance of ranging in land planning.Compare the advantages and disadvantages of traditional ranging and binocular vision ranging.1.Paddy field farming is an ecological model that combines farming and breeding.Rice and aquatic products live in the same space.In order to avoid competition among rice fields,a new method is proposed to measure the distance between rice fields using machine vision technology.The combined farmers provide data support.2.Set up a binocular 3D reconstruction ranging hardware and software platform,and analyze the ranging process as follows: using MATLAB dual target fixed box to obtain distortion coefficient,binocular correction of the image to be measured,and comparison of three stereo matching algorithms to obtain parallax The figure obtains a depth map,and obtains a three-dimensional reconstruction map of the object to be tested according to the depth information and the original image.3.Select the characteristic terraces of the rice-field comprehensive breeding(rice-fish-duck)model of Yuanyang County,Hani and Yi Autonomous Prefecture,Yunnan Province as the experimental site,and adopt the field binocular 3D reconstruction ranging for terraced fields,compared with the artificial fiber tapemeasure.The results of 8 groups of experiments show that the error is within 5%.Finally,the area of the paddy field can be obtained according to the three-dimensional information of the water surface.In summary,the research on binocular ranging in this paper has certain application value in rice field culture area information collection.
