PAGE Kinect在农产品采集方面的应用 本科毕业设计 Kinect在农产品采集方面的应用 摘 要 快速、准确、实时获取农作物涨势图像信息已经成为数字农业生产管理的趋势和必要手段，而深度图像信息包含彩色图像所没有的三维信息，是农作物信息采集的重要补充。本文采用微软公司开发的一款廉价传感器设备Kinect for Windows尝试用于农产品采集方面的应用，包括在水稻图像的预处理、水果分级系统等方面的应用，旨在于将高科技技术应用于精细农作业的生产与管理，让农作业的生产与管理更加科学与方便化。 本文先是对Kinect在各个领域上的应用进行阐述，然后深入探究了Kinect的构造和工作原理，继而对Kinect的深度成像进行了初步研究，论文在水稻冠层和水果分类做了初步探索，利用Kinect获取水稻及水果的RGBD图像，根据其深度信息，从空间维度，将水稻冠层进行快速分割、提取，为后续水稻冠层信息分析打下基础。利用深度信息及几何原理获取水果的高度和直径，可为水果分级提供依据。 关键词：Kinect RGBD 水稻冠层分割 深度信息 Kinect in the acquisition of agricultural products Ruan XiaoZhao (College of Engineering, South China Agricultural University, Guangzhou 510642, China) Abstract: Fast, accurate, real-time acquisition of crop rise image information has become a necessary means of digital agriculture production and management trend, but the depth image information contains no 3D information of color image, is an important supplement to the crop information collection. This paper uses a low-cost sensor devices called Kinect for Windows developed by the Microsoft Corp attempts to application for agricultural products of the acquisition, including the application in rice image preprocessing, fruit grading system, aimed at the production and management of high-tech in fine agricultural work, make the production and management of agricultural work more scientific and convenient. This paper first elaborates on the application of Kinect in various fields, and then in-depth study of the structure and working principle of Kinect, and then to Kinect depth imaging is studied, the paper made a preliminary exploration in rice canopy and fruit classification, RGBD image acquisition of rice and fruit by Kinect, according to its depth information, from the spatial dimension, the rice canopy fast segmentation, extraction, analysis to lay the foundation for subsequent rice canopy information. The fruit to obtain using depth information and geometric principle of height and diameter, can provide the basis for the classificat
