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 simultaneously driving the display to display based on the color correction sample, as the color prediction value;

[0058] The color correction reverse 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 drive value required to determine the target color;

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

[0060] In the present embodiment 1, the abov...

Embodiment 2

[0091] In this embodiment 2, in order to solve the problem of color distortion and color inconsistency in the multi-screen display of the flight simulator, and overcome the defect of the flight simulator's poor flight experience, a color correction method for the multi-screen display of the flight simulator is provided.

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

[0093] S1: Create a color correction sample;

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

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

[0096] In Embodiment 2, the step S1 to establish a color correction sample specifically includes the following steps:

[0097] S101: According to the number of color bits in the visual system of the flight simulator, sampling is performed at certain intervals within the range of the digital drive value of the display,...

Embodiment 3

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

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

[0132] S1: Create a color correction sample;

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

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

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

[0136] S101: According to the number of color bits in 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 Denotes the i-th digital drive value sample....

Abstract

The invention provides a color correction method and system for multi-screen display of a flight simulator, and belongs to the technical field of flight simulators. On the basis of the color correction sample, predicting a CIE 1931 absolute tristimulus value when the display is driven at the same time to display, and taking the value as a color prediction value; a CIE 1931 absolute tristimulus value is used as a to-be-displayed target color representation form, a color correction model is established in combination with the color prediction value, and an optimal digital driving value required for displaying the target color is solved and determined; and the optimal digital driving value is utilized to control the display of a corresponding display, so that color correction of multi-screen display of the flight simulator is realized. According to the invention, accurate color control can be carried out on the visual system of the flight simulator, the problems of color distortion and inconsistent color development of multi-screen display of the flight simulator are solved, and the completely immersive flight experience of a driver in the flight simulator can be improved; and practical and effective technical support is provided for research, development, production and on-site correction 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 simulator used to simulate aircraft flight, which plays an important role in the development of new aircraft, training of flight-related personnel, and flight experience. The 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 scene outside the cabin seen by the driver, so that the driver can judge the attitude, position, altitude, speed and weather of the aircraft, and then take corresponding manipulations. 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 displa...
