Embodiment 1

[0055] Embodiment 1 of the present invention provides a color correction system for multi-screen display of a flight simulator, including:

[0056] building blocks for building color correction samples;

[0057] The color correction forward module is used to predict the CIE1931 absolute tristimulus value when driving the display at the same time based on the color correction sample, as the color prediction value;

[0058] The color correction inversion module uses the CIE 1931 absolute tristimulus value to represent the target color to be displayed, combines the color prediction value, establishes a color correction model, and solves the optimal digital driving value required to determine the display target color;

[0059] The control module is used to control the corresponding display by using the optimal digital drive value to realize the color correction of the multi-screen display of the flight simulator.

[0060] In the present embodiment 1, the above-mentioned system is...

Embodiment 2

[0091] In the second embodiment, in order to solve the problems of color distortion and inconsistent color rendering of the multi-screen display of the flight simulator, and overcome the defect of poor flight experience of the flight simulator, a color correction method for the multi-screen display of the flight simulator is provided.

[0092] like figure 1 As shown, the color correction method for the multi-screen display of the flight simulator in this embodiment 2 includes the following specific steps:

[0093] S1: Create a color correction sample;

[0094] S2: Establish a color correction forward model;

[0095] S3: Build a color correction inverse model.

[0096] In this embodiment 2, the step S1 establishing a color correction sample specifically includes the following steps:

[0097] S101: According to the color bits of the visual system of the flight simulator, sampling at a certain interval within the range of the digital drive value of its display to establish a s...

Embodiment 3

[0130] In Embodiment 3, a color correction method for multi-screen display of a flight simulator provided by this embodiment is described in detail by taking a flight simulator visual system including three displays and 8 color bits as an example.

[0131] In the present embodiment 3, the provided color correction method for the multi-screen display of the flight simulator includes the following steps:

[0132] S1: Create a color correction sample;

[0133] S2: Establish a color correction forward model;

[0134] S3: Build a color correction inverse model.

[0135] 1. Establishing a color correction sample specifically includes the following steps:

[0136] S101: According to the color bits of the visual system of the flight simulator, sampling is performed at certain intervals within the range of the digital drive value of the display, and a sample of the digital drive value is established, denoted as d i , d i Represents the ith digital drive value sample.

[0137] In E...

Abstract

The invention provides a color correction method and system for multi-screen display of a flight simulator, belonging to the technical field of flight simulators. The color correction sample is constructed; based on the color correction sample, the CIE 1931 absolute tristimulus value when the display is driven simultaneously is predicted as Color prediction value; take the CIE 1931 absolute tristimulus value to represent the target color to be displayed, combine the color prediction value, establish a color correction model, and solve the optimal digital driving value required to display the target color; use the optimal digital driving value Control the corresponding display to realize the color correction of the multi-screen display of the flight simulator. The invention can accurately control the color of the visual system of the flight simulator, solve the problems of color distortion and color rendering inconsistency in the multi-screen display of the flight simulator, and help improve the fully immersive flight of the pilot in the flight simulator. experience, and provide practical and effective technical support for the R&D, production and on-site calibration of the flight simulator visual system.

Description

technical field [0001] The invention relates to the technical field of flight simulators, in particular to a color correction method and system for multi-screen display of flight simulators. Background technique [0002] A flight simulator is a kind of simulator used to simulate the flight of an aircraft. It plays an important role in the development of new aircraft, the training of flight-related personnel, and the flight experience. A flight simulator is mainly composed of a visual system, a simulated cockpit, a motion system and a computer system. Among them, the visual system is used to simulate the outside scene seen by the pilot, so that the pilot can judge the attitude, position, altitude, speed and weather of the aircraft, and then take corresponding maneuvers. The visual system is generally presented through projection or display, and in order to provide an immersive flight environment, multiple projection systems or multiple displays are often used for splicing di...
