普通数码相机摄影提取森林经营信息与建模研究

In this study, ordinary digital camera kind of quantitative measurement of single wood and forest stands, and research to meet the the necessary forest measurement accuracy barcode logo, and a known coordinate baseline set in stands, shooting with a baseline to control the depth ofField ordinary digital camera to a photo or 3D digital camera to a relatively obtain a single tree or stand, through the establishment of the mathematical model between the object space coordinates like square coordinate conversion plots measured tree learning, automatic extraction of trees speciesany height diameter, tree height and relative coordinates, and thus obtain single wood and plots, including volume, accumulation, biomass density, advanced density information to establish the model of the forest digital photography plots for forest surveys inside and outside the industry, one of theof new theoretical techniques and methods, turn forest information to digital images and three-dimensional model of the form of research, to improve the efficiency and automation of plot observation process analysis, to overcome the past sample information measuring operation is complex, labor-intensive, informationsingle defect.

本研究应用普通数码相机对单木及林分样地进行定量计测，研究能够满足森林计测必要精度的条码标志，并在林分中设置一条已知坐标基线，用基线来控制拍摄深度，外业普通数码相机拍摄一张相片或3D数码相机拍摄一个相对，通过建立物方坐标与像方坐标之间的数学模型转换获取单木或林分的样地测树学信息，自动提取树木树种、任意高处的直径、树高及相对坐标，进而获取单木及样地包括材积、蓄积、生物量、密度、进阶密度等信息，建立森林数字摄影样地模型，为森林调查内外业一体化提供新的理论技术和方法，进而以数字影像及三维模型形式研究森林信息，提高样地观测处理分析的效率和自动化程度，克服了以往样地信息计测中作业复杂、劳动强度大、信息单一等缺陷。
