Abstract: Nowadays, there is no low-cost fruit nondestructive testing method in China. The study aims to put forward a method about acquiring the moisture content of fruits indirectly by general photographic equipments. Firstly, general photographic equipment is used to obtain pictures of fruits or vegetables. Secondly, with the help of Matlab and Photoshop, the surface glossiness of the fruit or vegetable is gained. Thirdly, moisture content of a fruit or vegetable is measured through infrared moisture meter. Meanwhile, a Mathematical Model in Regression Analysis between the R value and the moisture content is established. Lastly, the non-linear relation between surface glossiness and moisture content of the fruit is found. Therefore, a new method about measuring the moisture content of fruits or vegetables through general photographic equipments is sought out.
