Problems solved by technology

[0008] The existing technology adopts the idea of ​​linearization, but because the brightness output by the projector is very non-linear, so when the RGB smooth curve of 255 white is adjusted, the effect of other colors will generally be poor; and when the color of the projector When the monotonicity of the change is poor, or when the decay regularity is not strong, the mathematical function may not always be able to adjust to a satisfactory effect
[0009] In summary, the existing technologies mostly use manual adjustment, the debugging time is uncontrollable, and the technical ability of personnel is required to be high, otherwise it will be difficult to achieve better results, and the debugging cost will increase

Embodiment 1

[0034] This embodiment discloses a fusion band adjustment method for image fusion processing. The adjustment method of this embodiment will be described in detail below by taking the adjustment of a fusion band as an example.

[0035] like figure 1 As shown, the adjustment method disclosed in this embodiment includes:

[0036] Step S11, extracting at least two color samples of the fusion zone. In this embodiment, the color sample point may be black, white, grayscale, or solid color, or may be a mixed color other than black, white, grayscale, or solid color.

[0037] Preferably, before performing this step, the color gamut space of each projector can be uniformly divided, and then the R, G, and B values ​​of the fusion band color samples can be extracted from each color scale division point. The so-called unified segmentation means that all projectors in the same fusion processing system follow the same segmentation rule, so that each fusion zone is adjusted according to the...

Embodiment 2

[0072] This embodiment discloses a fusion band adjustment method for image fusion processing, which mainly uses the attenuation curve of each color sample point obtained in the above embodiment.

[0073] like figure 2 As shown, the fusion band adjustment method disclosed in this embodiment includes:

[0074] Step S21 , acquiring the coordinates of the pixel point to be projected and its first color information. The "coordinates of pixel points to be projected and their first color information" generally refers to the acquisition or projection of the "coordinates of pixel points to be projected and their first color information" in the corresponding projector by the second adjustment device such as the fusion processor in the fourth embodiment described below. The coordinates of the pixel point to be projected and the first color information intercepted (also referred to as: interception) before the "first color information" will not be described in detail later.

Embodiment 3

[0087] This embodiment discloses a first adjusting device, and the first adjusting device is used to execute the method related to the first embodiment above. The non-exhaustive aspects of the technical solution of this embodiment can be understood by referring to the first embodiment above.

[0088] like image 3 As shown, the first adjusting device disclosed in this embodiment includes:

[0089] Color sample point extraction module 31, used to extract at least two color sample points of the fusion zone, the color sample point can be black, white, grayscale, pure color, or other than black, white, grayscale, pure color mixed color;

[0090] The adjustment module 32 is configured to attenuate each color sample point of the fusion zone to obtain a fusion zone attenuation curve of each color sample point.

[0091] Optionally, the above-mentioned color sample point extraction module includes:

[0092] A segmentation unit 311, configured to uniformly segment the color gamut sp...

Abstract

The invention discloses an integration band adjusting method for image integration processing, an adjusting device and an integration band adjusting system for image integration processing. The method for adjusting at least one integration band comprises steps that: at least two color sample points of the integration band are extracted; attenuation of the various color sample points of the integration band is carried out to acquire integration band attenuation parameters of the various color sample points.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a fusion band adjustment method, device and system for image fusion processing. Background technique [0002] The edge fusion processor system (also known as image fusion processing system) is a solution for image projection fusion processing, which is to overlap the edges of the pictures projected by a group of projectors, and display a brighter image without gaps through fusion technology. , Super large, high-resolution whole picture, the effect of the picture is like a picture projected by a projector, which is widely used in command centers, video conferencing, multimedia multi-function halls, etc. [0003] The key technologies of the edge fusion processor system are mainly geometric correction technology, color correction technology, edge fusion technology and other image processing technologies. The edge fusion processor (abbreviated as fusion processor) ne...
