Abstract

A transparent display method and transparent display device are disclosed. The transparent display method includes: obtaining a spatial position of eyes of a viewer at a side of a display screen with respect to the display screen; obtaining a spatial position of at least one key point of an object at the other side of the display screen with respect to the display screen; calculating a projection position of the at least one key point on the display screen with respect to the viewer'"'"'s eyes in accordance with the spatial position of the viewer'"'"'s eyes with respect to the display screen and the spatial position of the at least one key point with respect to the display screen; and adjusting an image displayed on the display screen in accordance with the projection position.

mapping the spatial position of the viewer'"'"'s eyes with respect to the display screen, the spatial position of the at least one key point with respect to the display screen and a plane where the display screen is located into a same spatial coordinate system;

calculating an intersection position of a line connecting each of the at least one key point with the viewer'"'"'s eyes and a plane where the display screen is located to obtain at least one projection point; and

transforming a position of the at least one projection point in the spatial coordinate system into a position on the plane where the display screen is located, to be used as the projection position.

15. The transparent display method of claim 13, wherein the stop of obtaining the spatial position of eyes of the viewer at the side of the display screen with respect to the display screen comprises:

capturing the viewer at the side of the display screen by a camera module fixed at a preset position of the display screen to determine in the captured image the spatial position of the viewer'"'"'s eyes with respect to the display screen.

16. The transparent display method of claim 13, wherein the step of obtaining the spatial position of the at least one key point of the object at the other side of the display screen with respect to the display screen comprises:

obtaining a pre-stored spatial position of the at least one key point with respect to the display screen or obtaining the spatial position of the at least one key point with respect to the display screen provided by a third-party device.

17. The transparent display method of claim 13, wherein the step of adjusting the image displayed on the display screen in accordance with the projection position comprises:

adjusting at least one graphic in current image in accordance with the projection position,

wherein the at least one graphic is adjusted by at least one of translation, rotation, enlargement, reduction, redrawing, segmentation, deletion and addition.

25. The transparent display method of claim 14, wherein the step of adjusting the image displayed on the display screen in accordance with the projection position comprises:

adjusting at least one graphic in current image in accordance with the projection position,

wherein the at least one graphic is adjusted by at least one of translation, rotation, enlargement, reduction, redrawing, segmentation, deletion and addition.

26. The transparent display method of claim 15, wherein the step of adjusting the image displayed on the display screen in accordance with the projection position comprises:

adjusting at least one graphic in current image in accordance with the projection position,

wherein the at least one graphic is adjusted by at least one of translation, rotation, enlargement, reduction, redrawing, segmentation, deletion and addition.

27. The transparent display method of claim 16, wherein the step of adjusting the image displayed on the display screen in accordance with the projection position comprises:

adjusting at least one graphic in current image in accordance with the projection position,

wherein the at least one graphic is adjusted by at least one of translation, rotation, enlargement, reduction, redrawing, segmentation, deletion and addition.

18. A transparent display device, comprising:

a processor; and

a memory for storing instructions executable by the processor;

wherein the processor is configured to;

obtain a spatial position of eyes of a viewer at a side of a display screen with respect to the display screen;

obtain a spatial position of at least one key point of an object at the other side of the display screen with respect to the display screen;

calculate a projection position of the at least one key point on the display screen with respect to the viewer'"'"'s eyes in accordance with the spatial position of the viewer'"'"'s eyes with respect to the display screen and the spatial position of the at least one key point with respect to the display screen; and

adjust an image displayed on the display screen in accordance with the projection position.

19. The transparent display device of claim 18, wherein the processor is further configured to:

a map the spatial position of the viewer'"'"'s eyes with respect to the display screen, the spatial position of the at least one key point with respect to the display screen and a plane where the display screen is located into a same spatial coordinate system;

a calculate an intersection position of a line connecting each of the at least one key point with the viewer'"'"'s eyes and a plane where the display screen is located to obtain at least one projection point; and

a transform a position of the at least one projection point in the spatial coordinate system into a position on the plane where the display screen is located, to be used as the projection position.

20. The transparent display device of claim 18, wherein the processor is further configured to:

capture the viewer at the side of the display screen by a camera module fixed at a preset position of the display screen to determine in the captured image the spatial position of the viewer'"'"'s eyes with respect to the display screen.

21. The transparent display device of claim 18, wherein the processor is further configured to:
