A novel method for the acquisition of full-color three dimensional(3-D) images of real objects was proposed based on multiple projections.In order to improve sampling efficiency,an orthogonal scanning mode was presented,instead of conventional 2-D scanning mode,to capture a series of projection images by a color charge coupled device in both vertically and horizontally direction with an incoherent light source.The 3-D Fourier spectra were extracted by using the projection images.The computer-generated hologram(CGH) was synthesized and the numerical 3-D image was reconstructed.The experimental results show that the acquisition method of multiple projection view images has good performance,high efficiency.Moreover,a new extraction method was adopted to improve viewing quality of 3-D imaging by using the multi-circle sampling area.Comparison with experimental result shows that more available data is used to synthesize the CGH and a significant improvement in image definition. |
