Embodiment Construction

[0044] In the existing projection technology, when the projected picture is projected on the speaker, it will not only interfere with the lecturer's speech, but also prevent the audience from watching the projected picture.

[0045] In view of this, the embodiment of the present invention proposes an intelligent projection technology, which can use image capture technology and image processing technology to detect whether the user (speaker) blocks the projected image. When the user blocks the projected picture, the position of the projected picture can be adjusted adaptively. In this way, the situation that the projected image is blocked by the user can be effectively improved. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings, which illustrate exemplary embodiments of the present invention, wherein the same reference numerals indicate the same or similar steps.

Abstract

The invention discloses a projection method and a projection system. The projection method comprises the following steps of: projecting a picture into a projection region according to picture data; then shooting the projection region and a user so as to produce an image, wherein the image comprises a picture region corresponding to the picture and a user region corresponding to the user; and adjusting the position of the picture projected on the projection region according to a relative position relation between the picture region and the user region. Therefore, the situation that the pictureis projected onto the user can be improved.

Description

technical field [0001] The present invention relates to a projection technology, in particular to a projection technology that can improve the situation that a projected picture is blocked by a user. Background technique [0002] At present, it is quite difficult to manufacture a large-size display, and the display effect is not only bad, but also the cost and price are quite expensive. Therefore, in a lecture or lecture environment, the speaker usually uses a projector to project the content to be shared onto a large screen or a wall to achieve a better sharing environment. [0003] Since it is necessary to adjust the position of the projected picture on the screen, it can only be realized by moving or manually correcting the projector, and it is quite time-consuming. Therefore, before giving a speech, the projector is usually configured in a specific position, such as being fixed on the ceiling or placed on a table, so that the projector can accurately project the picture...
