使用彩色深度攝影機之三維足部量測

Abstract

在生活中選擇一雙舒適和腳的鞋子是一個非常重要的議題，然而現在很少有些系統或是方法來準確或是有效的量測我們足部的資料，來提供我們選擇一雙適合的鞋子。在本篇論文中，我們發展一套快速的足部量測系統來獲得使用者的足部資訊。我們實作了一個快速可靠的自動對位的方法，利用有深度資訊的攝影機(RGB-D Camera)取得不同視角之3-D足部資料，重建出使用者的足部模型。透過建置的足部模型，我們可以量測足部的詳細參數，例如長度，寬度或足圍(girth)等參數。我們有設計實驗來進行我們系統表現的測試，而結果顯示我們的系統可以量測出準確且穩定的足部數值。除此之外我們將系統改為手持單台攝影機的操作方式，參與Intel Perceptual Competition獲得優異的成績。

Selecting a pair of comfortable shoes is a big issue in our life. However, there are few methods or system that can estimate our foot accurately to help us find the shoes. In this paper, we develop a fast foot dimension measurement system to provide useful information for selecting the shoes. Our foot measurement system uses a RGB-D Camera to obtain 3-D foot point cloud data at different view angles. We implement a fast and reliable automatic registration method to reconstruct a 3-D foot model. Based on the reconstructed 3-D foot model, we can compute the foot parameters, e.g. width, length, girth et.al. Experiences are conducted to evaluate the performance of our system. The results confirm that the performance of our system can provide a robust and accuracy foot dimension value.
