植物冠层三维结构获取技术的研究进展

DEVELOPMENT OF RESEARCH ON ACQUISITION TECHNOLOGY OF THREE-DIMENSIONAL STRUCTURE OF PLANT CANOPY

随着农业信息化的迅速发展,植物数字化再现技术已成为国内外的研究热点。其中,利用植物三维冠层结构提取的方法来重构数字化植物成为近年来关注的焦点,且该方法得到了进一步的推广。主要从双目视觉、光度立体视觉、激光扫描、超声波等技术手段对植物三维冠层立体图像获取展开阐述,并对各自的优缺点进行归纳总结和对比分析,最后对植物三维冠层结构提取的发展前景作出展望。

With the rapid development of agricultural informatisation,the technologies of digital reproduction of plant have become global focused research.Among them,one method has been the focus drawing attentions in recent years,that is,to utilize the extraction of three-dimensional canopy structure of plant to reconstruct digital plants,and the method has been further promoted for application.In the study we present elucidations on various technical means for three-dimensional stereo canopy image acquisition including binocular vision,photometric stereo vision,laser scanning and ultrasonic technology,also,the summarisation and comparative analyses on their advantages and disadvantages are carried out as well.The development prospect of the extraction of three-dimensional canopy structure of plant is forecasted at the end of the paper.
