Search Symbol (Half-width)	Description of Search Symbols
Space	"AND" indicates the intertwining of key terms used in a search
Double Quotation Marks ("") ( " " )	Double quotation marks indicate the beginning and end of a phrase, and the search will only include terms that appear in the same order of those within the quotations. Example: "image process" ： " image process "
?	Indicates a variable letter. Entering two ? will indicate two variable letters, and so on. Example: "Appl?", search results will yield apple, apply… e , appl y … ( (often used to English word searches) )
*	Indicates an unlimited number of variable letters to follow, from 1~n. Example: Enter "appl*", search results will yield apple, apples, apply, applied, application…(often used in English word searches) e , appl es , appl y , appl ied , appl ication … ( (often used to English word searches) )
AND、OR、NOT	Boolean logic combinations of key words is a skill used to expand or refine search parameters. (1) AND (1) AND: Refines search parameters (2) OR (2) OR: Expands search parameters (3) NOT: Excludes irrelevant parameters

DOI stands for Digital Object Identifier （ D igital O bject I dentifier ） ,
and is the unique identifier for objects on the internet. It can be used to create persistent link and to cite articles.

Using DOI as a persistent link

To create a persistent link, add「http://dx.doi.org/」「 http://dx.doi.org/ 」 before a DOI.
For instance, if the DOI of an article is 10.5297/ser.1201.002 , you can link persistently to the article by entering the following link in your browser: http://dx.doi.org/ 10.5297/ser.1201.002 。
The DOI link will always direct you to the most updated article page no matter how the publisher changes the document's position, avoiding errors when engaging in important research.

Cite a document with DOI

When citing references, you should also cite the DOI if the article has one. If your citation guideline does not include DOIs, you may cite the DOI link.

DOIs allow accurate citations, improve academic contents connections, and allow users to gain better experience across different platforms. Currently, there are more than 70 million DOIs registered for academic contents. If you want to understand more about DOI, please visit airiti DOI Registration （ doi.airiti.com ）。

Parallel Abstract 〈TOP〉

In this thesis, we present a 3D reconstruction system that integrates multi-view RGBD images acquired with Kinect for an object sitting on a turntable. In the proposed system, we first segment the object from images by using a simple background model with depth and produce the 3D point cloud from the RGBD image in a single view. Next, we compute feature correspondences between each pair of successive frames by SURF, and remove the false feature correspondences by applying RANSAC affine matching for each pair of adjacent views. Then, we use all the verified 3D feature correspondences to determine the geometric transformation that transforms the 3D coordinates from the corresponding camera coordinates to a unified world coordinate centered at the turntable. Because of the cumulative error of rotation angles and other environmental variables, we propose a two-step refinement process by using the LM Optimization. Finally, we propose a novel point set simplification algorithm to simplify the integrated point dataset that reduces the density of 3D points in the overlapped regions. Experimental results are given to demonstrate superior 3D reconstruction results by using the proposed method on both real data and simulation data.
