Problems solved by technology
If the conventional integrated imaging technology is used, the complete stereoscopic information of the object cannot be reconstructed, which greatly affects the stereoscopic display effect
For the removal of occluders, the disclosed solutions are only effective for partially occluded 3D objects. When the target object is completely occluded, the above solutions will be difficult to achieve high-quality 3D display effect

The invention discloses a shaded three-dimensional object display method based on Fourier spectrum, and the method comprises two processes: the generation of a non-shaded rectangular projection disparity map and the construction of a three-dimensional image. The method comprises the steps: projecting a series of raster graphics with a determined function expression to a three-dimensional scene through a projector array; recovering the non-shaded rectangular projection disparity map through constructing an image analysis reconstruction algorithm, and achieving the complete reappearance of the shaded three-dimensional scene through integrated imaging and display. Meanwhile, the method is small in number of projection times, is simple in device, and is easy to implement.
Description
technical field [0001] The invention relates to an integrated imaging technology, in particular to a method for displaying an occluded three-dimensional object based on a Fourier spectrum. Background technique [0002] Integrated imaging is a naked-eye 3D technology that can reconstruct a 3D scene with full parallax and true color. It is divided into two processes: shooting and displaying. When shooting, the camera array is used to obtain the parallax information of the three-dimensional scene to generate a micro-image array; when displaying, the micro-image array reconstructs the three-dimensional scene in the viewing space through the corresponding micro-lens array according to the principle of reversible optical path. [0003] In a 3D scene, sometimes the target object is blocked by obstacles, such as the attached figure 1 shown. If the conventional integrated imaging technology is used, the complete stereoscopic information of the object cannot be reconstructed, thereb...
