Boundless projection control method

Abstract

The invention discloses a boundless projection control method, which is used for solving the problem that an actual image projected onto a background wall through a projector has an obvious boundary relative to the background wall in the related technology. The method comprises the following steps: marking an original background color of a projection picture as a first original color; controlling the camera to shoot the background wall to obtain a reference photo, and extracting the color of the background wall in the reference photo and recording the color as a reference color; selecting the projection picture with the first original color closest to the reference color, and recording the projection picture as a picture to be processed; for any to-be-processed picture, obtaining a corresponding to-be-processed picture through matching, judging whether the difference degree between the first target color and the second target color of the to-be-processed picture exceeds a preset value or not, if not, taking the to-be-processed picture as a final projection picture for executing the projection task, and if yes, replacing the to-be-processed picture with the projection picture of the corresponding to-be-processed picture. According to the invention, the background color in the actual image is closer to the color of the background wall.

Description

technical field [0001] The invention relates to the field of projection technology, in particular to a borderless projection control method. Background technique [0002] A projector is a device that can project images, videos, etc. on the background wall, and can be connected to a computer, DV, etc. through different interfaces to play the corresponding content. Therefore, it is widely used in homes, offices, Schools and entertainment venues, etc. [0003] In related technologies, the projected picture can be projected onto the background wall via a projector to obtain the corresponding actual image, and in order to fully project the projected picture on the background wall, the size of the actual image is usually smaller than the size of the background wall, so that the actual image Compared with the background wall, there is an obvious boundary, and this boundary will attract the user's sight to a certain extent, thus affecting the perception. [0004] At present, no ef...

Problems solved by technology

[0003] In related technologies, the projected picture can be projected onto the background wall via a projector to obtain the corresponding actual image, and in order to fully project the projected picture on the background wall, the size of the actual image is usually smaller than the size of the background wall, so that the actual image There is an obvious boundary relative to the background wall, and this boundary will attract the user's sight to a certain extent, thus affecting the perception

[0004] At present, there is no effective solution to the problem that the actual image projected on the background wall via the projector has a clear boundary relative to the background wall in the related art.
