本研究利用攝影機從事波浪立體攝影，應用影像處理技術分析波場，其過程包含影像內部校正、外部校正、影像匹配與立體影像重建。其中三維立體影像重建中之影像匹配是研究核心，本文結合極線幾何原理與標準化相關法進行影像匹配，提昇影像匹配的效率。為降低影像匹配的錯誤，本文應用三台攝影機，並發展一套檢核程序。研究結果顯示，引入第三台攝影機可檢核影像匹配之正確性，避免僅用兩影像產生匹配誤判的現象。經本研究結果發現，以23×23 pixels作為匹配視窗大小是最理想的結果。
本文設計兩種試驗探討立體攝影技術之量測準確度，第一是平面位置之驗證，在裝設有每方格40公分的磁磚房間進行。第二是高度量測之驗證，用模擬的靜態波浪板進行。立體影像重建之試驗結果不論平面(測距為3～6公尺)上和波高(3公分)上的誤差都小於5%，研究顯示攝影機和目標物之間的距離以及攝影機間的相機間距距離都是影響影像重建結果準確性的因素。本文研究也確定，相機的間距並不需無限延伸，相機之間距與拍攝距離之比值達一平衡時(相機間距/拍攝距離＝0.15)，其高度準確度將趨於定值(波高誤差在0.6公分以下)。

In this study, the camera in wave three-dimensional photography, image processing techniques applied analysis of wave field, its process consists of imaging the internal calibration, external calibration, image matching and three-dimensional image reconstruction. In which three-dimensional image reconstruction of the image matching is to study the core of this paper, Epipolar Geometry and Normalized Cross Correlation to image matching method to improve the efficiency of image matching. To reduce the image matching error, this paper, three cameras, and developing a nuclear program review. The results showed that the introduction of the third camera can seize the nuclear image matching accuracy and avoid a match with only two images of the phenomenon of miscarriage of justice. The findings of this study, to 23 × 23 pixels as the matching window size is the best result.
This paper designs two kinds of tests of three-dimensional photographic technique, the measurement accuracy, the first is the flat position of the certification, equipped with 40-centimeter square tiles each of the room . The second is a high degree of measurement of the verification, using a static wave plate. Three-dimensional image reconstruction of the test results regardless of plane (ranging from 3 to 6 meters) and in wave height (3 cm) on the errors are less than 5%, studies have shown that cameras and the distance between the target and the camera between the camera Spacing distances affect the results of image reconstruction accuracy factor. This study also determined that the spacing of the camera does not need an unlimited extension of the distance between the camera and the shooting distance than the value of a balance, its high degree of accuracy will tend to be value.
