Boundless projection control method

Abstract

The invention discloses a boundless projection control method, relates to the field of technical projection, and is used for solving the problem that an actual image projected to 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: controlling a camera to shoot a background wall to obtain a reference photo, extracting the color of the background wall in the reference photo and recording the color as a reference color; respectively expanding a purity range and a brightness range based on the reference purity and the reference brightness; recording the obtained projection pictures meeting the conditions as to-be-processed pictures; for any to-be-processed picture, putting the to-be-processed picture on a background wall, controlling the camera to shoot the background wall to obtain a to-be-processed picture, extracting a background color of the to-be-processed picture in the to-be-processed picture and a color of the background wall, and respectively recording the background color and the color as a first target color and a second target color, calculating the difference degree between the first target color and the corresponding second target color; and selecting the to-be-processed picture with the minimum difference degree as a final projection picture.

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.
