[0153] Embodiments of the present invention provide a naked-eye stereoscopic display method, such as figure 1 As shown, the method includes:

[0154] Step 101: Obtain a first image captured by the first camera of the stereo camera module when the infrared emitter emits infrared rays, and determine the first pixel coordinates of the infrared emitter in the first image.

[0155] In the embodiment of the present invention, the infrared transmitter is used to mark the user's viewing position. The infrared transmitter can be worn on the user's body, such as the head, or it can be set at a certain position outside the user, but it is necessary to make the spatial position of the infrared transmitter Changes accordingly as the viewing position of the user changes. When displaying, it will be displayed according to the spatial coordinates of the infrared emitter, so as to realize tracking display, that is, display according to the user's viewing position, and make adaptive adjustment...

Abstract

The invention provides a naked-eye three-dimensional display method and device. The naked-eye three-dimensional display method comprises the steps of acquiring a first image and a second image shot bya three-dimensional camera module when an infrared emitter emits infrared rays, and determining a first pixel coordinate of the infrared emitter in the first image and a second pixel coordinate of the infrared emitter in the second image, wherein the space position of the infrared emitter is changed along with the change of the watching position of a user; obtaining the spatial coordinate of theinfrared emitter according to the first pixel coordinate, the second pixel coordinate and a preset calibration function of a spatial coordinate system corresponding to the three-dimensional camera module; carrying out three-dimensional display according to the spatial coordinate of the infrared emitter, so that the display content viewed by the user is matched with the watching position of the user. The problem that the positioning accuracy is difficult to control due to the fact that the inner reference and the outer reference of a camera are used for watching position positioning is solved.

Description

technical field [0001] The present invention relates to the technical field of stereoscopic display, in particular to a naked-eye stereoscopic display method and device. Background technique [0002] With the development and maturity of the naked-eye 3D (Three Dimensional, three-dimensional) technology, more and more naked-eye 3D display products have appeared on the market, and the general public's attention and demand for the naked-eye 3D display products are also increasing. [0003] The existing mainstream glasses-free 3D display products usually superimpose a special spectroscopic device on the ordinary display. The spectroscopic device can refract images in different directions, so that the visual images of the left eye and the right eye can be separated, so that the left eye of the user can only After receiving the left-eye image, the right eye can only receive the right-eye image, and the left-eye image and the right-eye image have parallax, so that the user can watc...
