本計畫利用立體照相解析技術，開發一套水中量測器，以方便而快速的掌握魚體的體長與體高資料。經測試結果，對30-50公分的魚體而言，最佳的拍攝距離是1-2公尺，拍攝懸吊的魚體，與實際體長相比，準確度平均可以達到96%左右。在水槽中拍攝黃鰭鮪活魚的結果，平均準確度約90%左右，和魚體的姿勢有關。因此，結果顯示此一系統可用於測量水中活魚的大小。關鍵詞：箱網養殖、魚體測量、立體照相

The stereogram technology had been used to develop an underwater fish size measuring system in this program. The body length and body height of living fish can be conveniently, rapidly derived by calculating the paired photos. For the length of 30-50 cm suspended fish, the measuring results showed that the average accuracy was about 96% comparing to the real body length. For living yellowfin tuna cultured in the water tank, the average accuracy was about 92%, related to the swimming posture of fish. Therefore, the results show that this system can be successfully used to measure the body length and body height of living fish in water.
