摘要: 根据标准参照物确定梨果实尺寸的计算机2D图像处理模型,开发了基于AForge.net图像类库和MatLab图像处理工具的梨果实尺寸测定软件工具包。结果表明,利用该工具包可对一幅果实2D数字图像内多个果实的多个表型(果实纵径、果实横径、果形指数、果实截面积、果心纵径、果心横径与果梗长度)进行精确度量,具备准确、快速、易于操作等优点,有一定推广应用价值。此外,配套的图像采集装置与图像编辑工具可帮助研究人员建立规范的表型图像数据集。

Abstract: This paper introduce a fast size measurement system for pear fruit. By using computer digital image processing technology,an indirect digital measuring model based on standard objects was firstly built,then,a size measuring software kit of pear fruit phenotypes was developed by using AForge.net class libraries and MatLab image processing tools. Finally,the artificial measuring results were used to check the model and the software kit. Measurement results of software kit showed no significant differences with the control(manual measurement),neither in the case of single/multiple object(s)in one image file,nor in the case of fruits with different sizes. The software kit could be used to identify and measure multiple phenotypes of multiple pear fruits accurately in one 2D picture precisely,such as fruit height,fruit width,fruit shape index,fruit sectional area,fruit core height,fruit core width and stalk length,etc. In addition,this size measurement system is rapid,accurate and easy to use,which could be applied for the phenotypic analysis of other similarly sized fruits,like peach & tomato,and for other organs,such as seed and leaf. Besides,the image acquisition device and image editing tools can help researchers to establish normative phenotypic image data sets,which should be promote the standardization and informationization of phenotypic analysis work.
