摘要

本文在此研究機器視覺系統應用在魚苗計數之可行性技術，研究重點在探討精確計數魚苗的影像處理方法。文中採用較低成本的視覺系統，配合撰寫高效率的影像處理軟體，使能滿足線上計數作業的要求，影像處理所採用的方法與流程爲：影像凍結→二值化→開運算→閉運算→遞迴計數。試驗結果得知碗盤內魚苗在70隻內，計數準確率可達99％以上，所花的計算時間約3秒。

This paper studies the feasibility of applying machine vision technique to minnows-counting. The content of the present study is focused on the exploration of image processing method. Also, the cost-effective machine vision system associated with programming a high efficient software of image processing is developed to meet the requirement of on-line operation. The steps of image processing methods for accurately counting minnows is: Freezing image→Binarying image→Opening operator→Closing operator→Counting minnows by recursive method. The results of testing indicate that the accuracy of counting minnows approaches above 99% as the numbers of minnows in shallow bowl is less than 70 numbers. The overall computational time of image processing for the present program requires about 3 seconds.
