摘要
提出一种专门针对航空随机场景的建模方法在采集得到航空随机二维图像后,对随机图像采集角点图像,特征点转换到HSV空间内,去除航空随机场景中的干扰,对比图像中某点的像素值和其在阴影区域中的像素值,若某点的阴影像素值包含的色度值、亮度值以及饱和度满足相应的阀值,在进行双目立体视觉的三维重建,保证视觉计算的真实性。后期的计算机仿真实验证明,改进算法能够有效的消除运动状态下的视觉阴影。
In this paper, a special study aviation random scene modeling method, after the acquisition for aviation random two-dimensional image, the image of random Angle image acquisition point, feature points to HSV space, get rid of inter-ference of aviation random scene, contrast of the image pixel values of a point and its pixel values in the shaded area at some point if the shadow of the pixel value contains the chromaticity value, brightness and saturation satisfy the corre-sponding threshold, the binocular stereo vision, three-dimensional reconstruction, guarantee the authenticity of the visual calculation. Later the computer simulation experiment proves that the improved algorithm can effectively eliminate the movement state of visual shadow, increase aviation random virtual simulation scenario the real degree of flight environ-ment.
