【摘要】：在航天測繪時,小基高比立體測繪可以較好地避免大基高比的不利因素,有效減弱遮擋、輻射差異、幾何畸變和陰影等因素對測繪精度的影響,在城市立體測繪中具有更多的優(yōu)勢。小基高比立體測繪需要對基高比數(shù)據(jù)值的優(yōu)化設(shè)計進行研究,文章通過仿真分析了影響小基高比立體測繪高程精度的主要因素,搭建了不同密度和高度建筑物的場景,進行了不同基高比和噪聲的仿真成像,最終結(jié)果表明,基高比、場景、遮擋以及噪聲的不同均會對測繪精度產(chǎn)生影響;當?shù)匚锬繕烁叱淘礁�、場景越�?fù)雜時,其最優(yōu)基高比越小,而由噪聲造成的誤差越大。
[Abstract]:In space mapping, the three-dimensional mapping with small ratio of height to height can avoid the adverse factors of large ratio of height to height, and effectively weaken the influence of factors such as occlusion, radiation difference, geometric distortion and shadow on the precision of surveying and mapping. In urban three-dimensional mapping has more advantages. It is necessary to study the optimum design of the base height ratio data value in the small base height ratio stereo mapping. The main factors influencing the elevation precision of the small base height ratio stereo mapping are analyzed by simulation, and the scenes of different density and height buildings are built. The simulation results of different ratio of base height and noise show that the difference of base height ratio, scene, occlusion and noise will affect the precision of surveying and mapping, and the higher the height of local object, the more complex the scene. The smaller the optimal base height ratio is, the greater the error caused by noise is.
