Automatic and efficient plant leaf geometry parameter measurement offers useful information for plant management. The objective of this study was to develop an efficient and effective leaf geometry parameter measurement system based on the Android phone platform. The Android mobile phone was used to process and measure geometric parameters of the leaf, such as length, width, perimeter, and area. First, initial leaf images were pre-processed by some image algorithms, then distortion calibration was proposed to eliminate image distortion. Next, a method for calculating leaf parameters by using the positive circumscribed rectangle of the leaf as a reference object was proposed to improve the measurement accuracy. The results demonstrated that the test distances from 235 to 260 mm and angles from 0 to 45 degrees had little influence on the leafs’ geometric parameters. Both lab and outdoor measurements of leaf parameters showed that the developed method and the standard method were highly correlated. In addition, for the same leaf, the results of different mobile phone measurements were not significantly different. The leaf geometry parameter measurement system based on the Android phone platform used for this study could produce high accuracy measurements for leaf geometry parameters.

SnS is a promising p-type semiconductor material for low-cost and low-toxic solar cells due to its exciting properties, such as high absorption in the visible range, little toxicity, inexpensiveness, and so on. The CdS nano-layer used as buffer layer of ZnO nanowire arrays/CdS/SnS thin film solar cells was prepared by thermal evaporation method. X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), atomic force microscopy (AFM), UV-Vis spectra, Hall effect measurement system and I-V measurement system were used to characterize the ZnO nanowire arrays/CdS/SnS thin film solar cells. It is found that the CdS nano-layer plays a key role in reducing the leakage current.
