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

An embodiment of the invention discloses a method and a device for determining grating parameters 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 actual values of the grating parameters 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 projection period of the grating, and determining a distance between an image acquisition device and the display screen; and determining the grating parameters of the grating, wherein the grating parameters comprise at least one of a grating placing distance and grating pitch. 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 technical field of stereoscopic display, in particular to a method, device and electronic equipment for determining grating parameters of a naked-eye 3D display device. Background technique [0002] People usually watch objects with both eyes at the same time. Due to the distance between the eyes of the human eye, the distance between the left and right eyes is about 65mm. , because the visual images received by the left and right eyes are different, the brain synthesizes the information of the two images of the left and right eyes to superimpose and regenerate the image, so that the viewer has a three-dimensional effect. At present, the mainstream naked-eye 3D (3-dimensional,) display device is to use the above principle, by superimposing a special grating on the conventional display, the grating can refract the image in different directions, so that the visual images of the left eye and the right eye are separated...
