Accuracy Assessment Of 3d Point Clouds Generated By Photogrammetry From Different Distances, Zhongming An

Dissertations, Master's Theses and Master's Reports

Photogrammetry is playing more important role in many industries today, and thanks to Structure-from-Motion, 3D point clouds and 3D meshes can be produced and be used as a resource for surveying and documentation.

In this project, the accuracies of Structure-from-Motion generated point clouds from pictures taken from different distances are assessed to determine if the distance has a significant impact on the accuracy and what kind of pattern the accuracies will show if there is any. Due to space limit, an improvised turntable was used in order to mimic the condition where camera moves around the object. Multiple images were …

Measuring Accuracy Of Two 3d Printing Materials, Mudassir Ali

Master of Technology Management Plan II Graduate Projects

Part accuracy is one of the important aspect in the manufacturing industry. The overall inaccuracy of the parts being built by RP technology has been one of the major challenges that need to be overcome. Though all the printing materials come with specifications, but the suppliers and manufactures does not specify the accuracy of the materials. In this study we established a study which compares the accuracy of the materials in consideration and performed an experiment to establish the superiority of a material in terms of accuracy over each other. The purpose of this project was to compare the dimensional …
