研究目的
To present a high-angular-resolution data-set created using a turntable arrangement for research in light field visualization, manifold learning, visual quality assessment, and evaluation of preferred object orientation.
研究成果
A high-angular-resolution data-set was created and presented, which is unique in providing an angular resolution of 2 views per degree and three views separated by known distance for every angular position. The data-set will be useful for studying the effect of view synthesis on the perceived quality of 3D content on a light field display.
研究不足
The data-set may not be suitable for machine learning tasks due to the small number of classes and instances per class. Some objects exhibited non-lambartian surfaces, and a wobble-like effect was observed due to improper object placement on the turntable.
1：Experimental Design and Method Selection:
A turntable arrangement was used to capture high-angular-resolution images of seven distinct objects from three camera positions for every half degree of rotation.
2：Sample Selection and Data Sources:
Seven distinct objects were selected and positioned on an automated turntable.
3：List of Experimental Equipment and Materials:
'Photobench 360' turntable by Ortery Inc., Nikon D5300 DSLR camera with 'AF-S DX Micro NIKKOR 40mm f/
4：8G' lens, and three standard tubular fluorescent lamps for lighting. Experimental Procedures and Operational Workflow:
Images were captured for every half degree of rotation, generating 720 images for each camera position. The camera was moved linearly between positions.
5：Data Analysis Methods:
The consistency of the turntable and the linear motion of the camera were verified. Camera calibration was performed using 'Camera calibration toolbox for MATLAB'.
