中文摘要:玉米器官三维模板资源库的构建能够为数字玉米技术体系的建立提供信息完整、具有高真实感的玉米器官三维模型。首先,对玉米植株进行结构单元划分,然后,通过分析玉米各器官的形态结构特征,从三维数据获取方式的角度制定玉米主要器官三维数据获取规范,按该规范开展玉米主要器官三维数据获取工作,并基于所获取的实测数据进行器官几何模型构建,最后,以所构建的玉米器官几何模型为内容,以品种、器官和生育时期等作为关键字构建玉米器官三维模板资源库。资源库包含了具有农学参数的多品种、多生育时期玉米器官几何模型,其构建将有利于数字玉米在玉米行业的各方面发挥作用,也为其他植物的三维模板资源库构建提供了参考。

Abstract:In order to provide three dimensional (3D) models with complete agronomic information and high fidelity for the construction of digital maize system, a 3D template resource library of maize organs was constructed. Firstly, maize plants were subdivided into basic structural units, including nodal root, lateral root, mesocotyl, stems, sheath, leaf, tassel and ear. Secondly, the data acquisition standard of major maize organs was established from the perspective of 3D data acquisition by analyzing the morphological and structural features of the organs. 3D data of the maize organs were acquired by using 3D scanners and 3D digitizers according to the standard, and geometric models of the maize organs were constructed on the basis of the measured 3D data. Finally, the 3D template resource library of maize organs was constructed by assembling these geometric models. The library took cultivar, organ name, growth period etc. as its key words for resource retrieval. It contained a large number of maize organ models of different cultivars and multiple growth periods with consistent agronomic parameters. The construction of the library would promote the digital maize system and played a great role in the research, production, promotion and demonstration of maize industry, it also provided a reference for the 3D resource library construction of other plants.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
