Problems solved by technology
Affected by factors such as manufacturing process and assembly errors, there is usually a certain deviation between the actual value of the grating parameter and the ideal design value. If the design value is directly used for display, it will cause the difference between the left and right eye viewing areas of the naked-eye 3D display device. The adjustment is inaccurate, which will affect the display effect of the naked-eye 3D display device

Embodiment Construction
[0139] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0140] It should be clear that the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0141] In order to enable those skilled in the art to better understand the present invention, first, a brief introduction is made to the inclination angle θ0 of the naked-eye 3D display device and the naked-eye 3D display device. The naked-eye 3D display device mentioned in the embodiment of the present invention includes a display screen and a grating arranged on the display screen. The grating may be any one that can be used in the naked-eye 3D display device in the prior art such as a slit grating ...

The invention discloses a method and a device for determining a grating inclination angle of naked-eye 3D display equipment, and electronic equipment, which relate to the field of three-dimensional display technologies, and can be used for determining an actual value of the grating inclination angle precisely. The method comprises the steps of: acquiring a first image, where the first image comprises a fringe image displayed by the naked-eye 3D display equipment, the naked-eye 3D display equipment arranges first color pixels and second color pixels on a display screen by utilizing a preset image arrangement period and a preset image arrangement inclination angle, and displays the fringe image with the aid of a grating; determining a fringe period of the fringe image and a fringe inclination angle; determining a projection period of the grating; and acquiring the grating inclination angle of the naked-eye 3D display equipment according to the image arrangement period, the image arrangement inclination angle, the fringe period, the fringe inclination angle and the projection period. The method and the device can be used for improving the display effect of the naked-eye 3D display equipment.
Description
Technical field [0001] The present invention relates to the field of stereo display technology, and in particular to a method, device and electronic device for determining the raster inclination angle of a naked-eye 3D display device. Background technique [0002] People usually view objects through both eyes at the same time. Because there is an interocular distance between the eyes, the distance between the left and right eyes is about 65mm. Therefore, when viewing the object, the gaze angles of the eyes are different, resulting in a certain degree of difference between the visual images received by the left and right eyes. Because the visual images received by the left and right eyes are different, the brain combines the information of the two images of the left and right eyes to superimpose and regenerate the images, so that the viewer has a three-dimensional feeling. At present, the mainstream naked-eye 3D (3-dimensional) display device uses the above principle to superimpos...
