- 摘要:
- 以‘高原红’海棠（Malus ‘Prairifire’）为试材，基于UAV成像技术采集物候期内图像样本并提取色彩参数值（CIE L*a*b*），计算不同采样点及不同物候期的色差值（△E），通过对比△E的变化情况实现海棠物候的动态监测，为实时掌握海棠物候动态变化情况，适时作出调整策略提供技术参考，同时也为开展花期物候调控相关研究提供参考依据。结果表明：1）利用Photoshop提取航拍图像色彩参数，并基于物候色彩参数进行聚类分析，将其物候划分为萌芽期、展叶期、蕾期、初花期、盛花期、末花期、落叶期、结果期、休眠期，建立了‘高原红’海棠物候色彩参数库；2）计算‘高原红’海棠各物候期内色差△E1及不同物候期间色差△E2范围，并基于各物候期内最大色差△E1max′及不同物候期间最小色差△E2min′，建立了基于色差参数的物候判别方法；3）随机提取了2个日期（3月22日、4月10日）的‘高原红’海棠物候图像色彩参数，通过聚类分析判定2个日期物候图分别处于蕾期和盛花期，结果与实际相符；2个日期物候图间色差（△E2′=21.8）大于蕾期至初花期最小色差（△E2min=9.6），表明此时物候期跨度较大，结果与实际相符。综上，该方法可便捷高效判断海棠花期等物候期情况。
- Abstract:
- Based on UAV imaging technology,images of the phenological period of Malus ‘Prairifire’ were collected，color parameter values (CIE L*,a*,b*) were extracted，and color difference values (ΔE) for different sampling points of phenological periods were calculated.The dynamic monitoring of the flowering phenology of crabapple was realized by comparing ΔE，in order to provide reference for grasping the dynamic phenological changes of crabapple in real time and making timely adjustment strategies，and also provide reference for flower phenological study.The results showed that,1) the color parameters of aerial images of M. ‘Prairifire’ were extracted by Photoshop software.The phenological periods were cluster analyzed based on the phenological color parameters，which could be divided into the germination stage，leaf spreading stage，budding stage，initial flowering stage，full flowering stage，final flowering stage，defoliation stage，fruiting stage，and dormant stage.2) The range of color differences in each phenology period (△E1) and of adjacent phenological periods (△E2) were obtained.A phenological discrimination method was established based on the maximum color difference △E1 max′ in each phenological period and the minimum color difference △E2 min′ between different phenological periods.3) The color parameters of M. ‘Prairifire’ phenological images on two dates (March 22th and April 10th) were randomly selected.The phenological periods of the two dates were determined by cluster analysis to be in the budding stage and full flowering stage respectively，which were consistent with reality.The color difference (ΔE2′) of phenological images between the two dates was 21.8，which was higher than theminimum color difference from the budding stage to the early flowering stage(△E2 min=9.6).This indicated a larger phenological span between these phenological images，which were consistent with reality.In conclusion，this method could easily and efficiently judge the phenological stage of the flowering crabapple.
