Abstract

The invention discloses an OpenGL-based binocular night vision imaging simulation method and system. A computer loads the imaging simulation method to generate an image on a pair of binocular night vision goggles. The method comprises the following steps of S1: building a three-dimensional scene model used for simulating an environment; S2: calculating a low light radiation value of each object model in a set environment to generate a low light radiation image; S3: according to position data of the head of a wearer, adjusting a visual position and a visual angle of the low light radiation image; S4: performing rendering processing on the low light radiation image by utilizing a shader algorithm to obtain a low light night vision goggle image; and S5: performing first adjustment on the lowlight night vision goggle image to form a first image presented in a left eyepiece, and performing second adjustment to form a second image presented in a right eyepiece, wherein the first adjustmentand the second adjustment are same in value and opposite in direction. The simulated image with the equivalent effect under the observation of a binocular night vision imaging system can be presentedin real time; and the simulated image is stable and reliable in quality.

Description

technical field [0001] The invention relates to an imaging simulation method, in particular to an imaging simulation method and system of an OpenGL-based binocular night vision goggle. Background technique [0002] The night sky is not completely devoid of light radiation. There are moonlight, starlight, atmospheric glow, and scattered light from the sun, moonlight, and starlight in the sky, but because the light amplitude is too small to be recognized by the human eye, it is called twilight. Twilight includes visible light and near-infrared light, with a wavelength of 0.4-2.0um. Low-light night vision technology uses electric vacuum and electron optics technologies to realize the conversion of photon image-electronic image-photon image, and in the conversion process, the photon image is enhanced by enhancing the electronic image, so as to achieve A technique for night observation under low-light illumination. [0003] With the improvement of computer performance and the ...
