應用立體視覺於人體掃描技術已在世界各國進行許久，而目前所有的人體掃描機擷取到的資料點尚未被有效的利用。主要的原因在於該些龐大且毫無結構的資料點並無人體特徵的辨識與量測，以及簡化為有意義的特徵結構。部分掃描機搭配的軟體可以人工的方式進行特徵辨識，但這樣對於特徵位置的判斷往往非常主觀，而得到的量身數據也會不可靠。本文發展一客觀快速的自動化量身系統，並且利用搜尋之特徵在電腦中重新建構人體模型。使處理過的資料點不但簡潔，且能完整的保有人體的主要特徵，可被廣泛的應用於娛樂工業、醫學研究、人因工程與動畫模擬…等。
本文介紹如何依據文獻上對人體特徵之描述轉化為數學定義。並撰寫演算法以電腦自動化方式搜尋人體特徵，並建立一保有人體特徵之電子人體資料結構，有效的簡化人體資料點。並利用人體結構化後之結果，進行自動化人體計測系統之開發。
要真正發揮3D人體掃描機之效能，不應僅限於在蒐集人體尺寸的計測資料。本研究所建立的人體結構化資料，像地球的經緯度一樣，每一點均代表人體各部位的幾何意義，如此人體3D的掃描資料才能被廣泛的應用於各行業，也期望往後能將此資料結構制定為世界之標準規範。

A Study of Automatic Anthropometry and Construction of Computer Manikins
The 3D body scanning technology has been developed for a long time worldwide. A body scanner can generate thousands of points from the surface of a human body. However, turning the scanned data into useful information for engineering purposes is still difficult. This is a prominent classic problem of a large amount of data, but little information. The key points to solve the problem are feature recognition and data simplification.
However, with current technology, not all the features can be automatic extracted. Some of the features still have to be located manually. The accuracy of anthropometric data will be subjective to human judgment, and the reliability of the results is poor. In this study, we developed an automatic anthropometric system and constructed a feature-based electronic manikin. The manikin can be used in garment design, medical and ergonomic researches, and movie amusement industry.
This thesis describes how to find the body features and to construct the computer manikins. First, the descriptions of human features in the literatures are translated into mathematical definitions. The search algorithms are coded into computer program. Then a patented data structure of the manikins is defined based on the body features. This very concise human model reduces the size of the data yet contains all the geometric features. Finally, an automatic anthropometry system is developed to measure the computer manikin.
The body dimension cannot reveal the shape of the geometric feature of human body. If we want to bring all the benefit of the 3D body scanner to industrial applications, we should not just limit to the collect the anthropometry data. Each point in the computer manikin, just like the latitudinal and longitudinal coordinate of the earth, represents a specific feature of the body. According to the structure data, the scanned data can be easily and widely used in many fields. It is expected that the computer manikins can be accepted as worldwide standard of human atlas.
