[0056] In the first embodiment of the projection method of the present invention, the method includes the following steps:

[0057] Step S10, providing a human-computer interaction interface for the user to move a preset control point, and generating a projected image according to the control point after the user moves;

[0058]Step S20, responding to the user's instruction to add a new control point, adding a new control point to the projected image;

[0059] Step S30, generating a new projected image according to the newly added control point moved by the user and / or the original control point moved by the user.

[0060] The projection screens in this embodiment and the following embodiments include: a projection wall, a projection screen, etc., and the present invention is not limited to the projection screen.

[0061] The terminal provides a human-computer interaction interface for the user to move a preset control point, and two-dimensional coordinates are set in the hum...

Abstract

The invention discloses a projection method and device. The embodiment of the present invention provides a human-computer interaction interface for the user to move a preset control point, and generate a projection image according to the control point after the user moves; respond to the user's instruction to add a new control point, and add a new control point to the projected image point; generate a new projected image according to the newly added control point moved by the user and / or the original control point moved by the user. Compared with the prior art, the embodiment of the present invention allows the user to add new control points when the user is dissatisfied with the generated projection image or needs to make further local adjustments, and use the newly added control points to adjust the original projection image. The local position of the image is further adjusted. Therefore, the projection method in the embodiment of the present invention is more flexible, so that it can not only adapt to the overall irregular projection screen, but also adjust a part of the projected image without affecting other parts of the projected image.

Description

technical field [0001] The invention relates to the field of graphics and image processing, in particular to a projection method and device. Background technique [0002] Current projectors usually provide keystone correction. Keystone correction is to process the trapezoidal projection image projected by the projector on the projection screen (such as projection wall, curtain, etc.), and correct the projection image projected on the projection screen to a standard shape. (such as a rectangle, etc.). Keystone correction is only suitable for relatively flat and regular-shaped projection screens. However, in actual use, some special projection screens are usually encountered, such as fan-shaped, spherical, and irregularly curved projection screens. When encountering these special projection screens, keystone correction cannot flexibly correct the image projected by the projector, nor can it freely adjust parts of the image. [0003] The above content is only used to assist ...
