3D Quantitative Evaluation System for Integral Photography based 3D Autostereoscopic Medical Display

摘要

3D autostereoscopic display techniques are used in medicine to assist surgeons to have a better knowledge on regions of interest. However, different 3D image generation algorithms and hardware implementations will bring out varied display quality. An objective and quantitative evaluation of clinical display is necessary. To evaluate the quality of 3D displays, we propose a quantitative evaluation system for 3D autostereoscopic medical display in this paper. The proposed evaluation system is composed of a 3D evaluation reference pattern, a 3D image acquisition platform and a quantitative analysis module. Moreover, we apply an integral photography based 3D autostereoscopic medical display to verify the feasibility and availability of the evaluation system. Based on quantification results of the 3D evaluation reference pattern and the 3D medical image, evaluation errors of the viewing angle, imaging depth as well as image quality are acceptable.
