项目摘要

Recently, for improving agricultural product qualities using of developing of new agricultural technology, the technique of a machine vision system has been using in the part of the plant cultivation, the color sorting and recognization of agricultural products. However, for establishing the utilization with respect to above improving techniques. It is necessary to clear the properties of agricultural products. Consequently, the study dealt with the properties with respect to the agricultural product qualities. The main results were as follow :(1) It is clear that the rice taste relates to process from drying to milling.(2) The growth measuring of a culture plant was within the range of possibility by using of the method of electricity and magnetism.(3) The performance of tomato break was within of possibility by the measuring of water potential.(4) The measuring method of persimmon tannin and of persimmon sugar was established.(5) The detection of fruits defected in visible wavelength region was complicated by the variation in color over the surface of fruits. But blush and ground color curves had about same values of spectral reflectance in near infrared region. And the spectral reflectance drew the clear distinction between normal and damage of fruit surface.(6) The shape of the crop within the distance of several tens cm from the sensor could be measured with fairly good accuracy and the fruits could be distinguished from leaves and stems by the difference color.(7) The estimating method of inner quality of agricultural products was within the range of possbility by measuring of a sound transmissibility.These above studies were edited as the agricultural product property research.

近年来，为了利用农业新技术的发展来提高农产品质量，机器视觉系统技术已被应用于农作物栽培、农产品颜色分选和识别等方面。然而，为了建立关于上述改进技术的利用率。要明确农产品的属性。因此，本研究探讨了与农产品品质有关的性质。主要研究结果如下：（1）米饭的食味与干燥到制粉的过程有关。(2)利用电磁法对栽培植物的生长进行测量是可行的。(3)通过对番茄叶片水势的测定，说明番茄叶片的破碎性能在可能的范围内。(4)建立了柿子单宁和柿子糖的测定方法。(5)水果表面颜色的变化使可见光区缺陷水果的检测变得复杂。而在近红外波段，红、底色曲线的光谱反射率基本一致。光谱反射率可以明显区分果实表面正常和受损。(6)在距离传感器几十厘米的范围内，可以测量作物的形状，具有相当好的精度，并且可以通过不同的颜色将果实与叶和茎区分开。(7)通过测量传递率，在可能的范围内对农产品内在品质进行评价，将上述研究编辑为农产品属性研究。
