ZooSCAN浮游動物圖像掃描分析系統(tǒng)主要用于對液體中的浮游動物樣品進行計數(shù)、大小測量、種類鑒定以及生物量測定。
ZooSCAN系統(tǒng)是由ZooSCAN、ZooProcess和Plankton Identifer (PkID)等共同組成的，ZooSCAN是硬件部分，主要進行浮游動物樣品掃描，形成數(shù)字圖像。ZooProcess和PkID是軟件部分，分別以標準化的程序處理原始圖像、對不同個體的形態(tài)參數(shù)進行自動測量和對圖像中的浮游動物進行自動分類和計數(shù)。其基本工作流程包括：1)掃描空白背景；2)掃描樣品，獲得原始圖片和元數(shù)據(jù)信息；3) 通過ZooProcess軟件，標準化原始圖片，提取并測量圖片中不同個體的形態(tài)參數(shù)；4) 通過PkID 軟件建立圖像培訓(xùn)數(shù)據(jù)庫并進行性能驗證；5) 針對已掃描的樣品圖像，進行浮游動物的自動識別，獲得不同類群浮游動物的數(shù)量；6) 形態(tài)學(xué)參數(shù)的提取與分析，可進一步獲得樣品的粒徑組成、生物學(xué)體積等信息。
應(yīng)用領(lǐng)域：生態(tài)學(xué)調(diào)查、漁業(yè)、水產(chǎn)養(yǎng)殖、教育。
近年，中國科學(xué)院海洋研究所科研人員利用ZooScan圖像掃描技術(shù)，建立膠州灣浮游動物優(yōu)勢種中華哲水蚤和強壯箭蟲體長、面積和體積與干重之間的回歸關(guān)系。比較了不同季節(jié)、不同參數(shù)之間的差異。結(jié)果表明，不同月份的回歸關(guān)系之間無顯著差異，在三個體型參數(shù)中，面積擬合生物量的程度最好，是利用圖像方法估算生物量最佳參數(shù)。中華哲水蚤和強壯箭蟲體型-生物量轉(zhuǎn)換關(guān)系可以分別表示為:lgDW=1.61lgA+1.69,lgDW=1.54lgA+1.32。
廠家對ZooSCAN進行了全面的升級換代，鑒于工作需要，中國科學(xué)院海洋研究所再次選購1套ZooSCAN浮游動物圖像掃描分析系統(tǒng)，極大地增強了海洋所膠州灣生態(tài)環(huán)境研究的能力。
