Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention aims to provide a method and a system for determining the position and the diffusion angle of an orientation diffuser, so as to determine the position and the diffusion angle of the orientation diffuser, realize the clear display of a scene with a large depth range and improve the visual experience of a light field display system based on integrated imaging.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
As shown in fig. 1, the present invention provides a method of determining the position and divergence angle of a directional diffuser, comprising the steps of:
step 101, acquiring parameters of a lens array of the light field display system based on integrated imaging and a distance between a display and the lens array.
The parameters of the lens array include a distance p between two adjacent lenses of the lens array, and a diameter a of the lens array.
The integrated imaging-based light field display system includes a flat panel display, a lens array, and a directional diffuser. The planar display is loaded with a unit image array generated according to a three-dimensional scene to be displayed. The light emitted by the display loaded with the unit image array is modulated for the first time through the lens array to recover a discrete light field, and the continuous light field is recovered through the secondary modulation of the directional diffuser. An image of the three-dimensional scene is ultimately generated.
Step 102, determining the position of the directional diffuser by determining the parallax of the same-name image points in different unit images according to the parameters of the lens array and the distance between the display and the lens array;
in the light field display system based on integrated imaging, the lenses in the lens array are generally large in size (larger than or equal to 2mm), and the situations of sparse arrangement or diaphragm existence exist generally, namely p is larger than or equal to a.
According to the characteristics of lens imaging, a Central Depth Plane (CDP) exists in the system, and the position of the CDP can be obtained according to the Gaussian theorem:
Figure BDA0002099592940000051
wherein d is1Representing the distance of the depth center plane from the lens array.
Current research shows that directional diffusers should be placed in the depth center plane, and research has not found that there is a necessary coupling relationship between the positions of the directional diffusers and the depth center plane. Instead, the position of the directional diffuser should be in the proper position for the object to be displayed.
As shown in fig. 2, this can only be achieved when the directional diffuser is located at the three-dimensional pixel locationThe image is now clearly imaged. When the directional diffuser is positioned right in the 3D image O1The light is accurately diffused without gaps and overlapping, as shown in fig. 3 (a). When the directional diffuser is positioned in the 3D image O1There is a large overlap of the diffused light rays with the lens array. As shown in fig. 3 (b). When the directional diffuser is positioned in the 3D image O1When the light is observed from the observer, a large gap exists between the diffused light and the observer. In summary, should be located right in the 3D image O1The location of the same. Since an actual 3D scene has a certain depth range, in actual operation, the directional diffuser should be located at the center of the depth range where the 3D scene is located.
And the position of the 3D image point can be determined by the disparity of the image points of the same name in the different unit images. As shown in the figure 3 of the drawings,
Figure BDA0002099592940000052
and l ═ y1) + y2, where p is the distance between two adjacent lenses of the lens array and l is the separation of the homonymous point between the two elemental images.
The position of the image point, i.e. the position of the directional diffuser, is:
Figure BDA0002099592940000061
step 103, determining the diffusion angle of the directional diffuser according to the light scattering principle according to the position of the directional diffuser and the parameters of the lens array.
As shown in fig. 4, the step 103 of determining the diffusion angle of the directional diffuser according to the position of the directional diffuser and the parameters of the lens array and the light scattering principle includes: using a formula based on the distance d between the directional diffuser and the lens array and the diameter a of the lenses of the lens array
