專利摘要(中)
一種咖啡生豆辨識方法，包括：藉由影像擷取裝置取得咖啡生豆的影像，其中影像包括多個像素；從記憶體中讀取對應咖啡生豆的平均值權重、標準差權重以及門檻值；從影像中擷取像素中每一者的紅、綠、藍三色的灰階值；根據三色灰階值的近似常態分佈計算出對應咖啡生豆的平均值與標準差；以及將平均值與標準差分別乘以平均值權重與標準差權重後相加以計算出總評分值；其中當總評分值小於門檻值時，將咖啡生豆辨識為合格豆。

專利摘要(英)
A green coffee bean identification method includes obtaining an image of a green coffee bean by an image capture device, wherein the image includes a plurality of pixels; reading an average value weight, a standard deviation weight, and a threshold value corresponding to the green coffee bean from a memory; extracting grayscale values of red, green and blue for each of the plurality of pixels from the image; calculating an average value and a standard deviation corresponding to the green coffee bean according to the approximate normal distribution of the grayscale values; and multiply the average value and standard deviation by the average value weight and the standard deviation weight respectively then summing to calculate a total scoring value; wherein when the total scoring value is less than the threshold value, the green coffee bean is identified as a qualified bean.
