    摘要:

    提出了一種基于超聲波傳感技術(shù)的溫室草莓冠層三維重構(gòu)與測量方法,用Matlab軟件的interp1()函數(shù)、quad函數(shù)、surf函數(shù)等進行溫室草莓冠層曲線、曲面的擬合并完成面積、體積的計算。以6壟溫室草莓冠層作為試驗對象,采用該系統(tǒng)對其進行3次重復(fù)試驗,與人工測量結(jié)果進行對比。分析結(jié)果表明,檢測結(jié)果的可重復(fù)性較好(R2為0.9275,RMSE為0.1358m3),與人工測量結(jié)果相一致(R2為0.9411,RMSE為0.1345m3),該方法具有較高的穩(wěn)定性及可行性。

    Abstract:

    A crop canopy 3-D reconstruction and volume measurement method that based on the ultrasonic sensing technology was proposed. The functions of interp1(), quad and surf in Matlab were introduced for crop canopy description and the volume calculation. Indoor measurements were conducted on six ridges of greenhouse strawberry by 3 times repeats and the results were compared with manual measurement. The result showed the experiments presented good repeatability(R2 was 0.9275, RMSE was 0.1358m3), which showed consistent with the manual measurement (R2 is 0.9411, RMSE was 0.1345m3). Therefore, the proposed measuring system was stabilized and feasible.
