平行式红外双目立体系统各参数合理效益取值

Reasonable benefit value of the parameters of the parallel infrared binocular stereo system

为解决当前夜间辅助驾驶仪平面显示的弊端以及在合理效益下获得丰富的立体层次感,文中从平行式红外双目夜视系统出发分析对比了红外双目系统和人眼立体感知的最小可分辨距离,结合人眼立体感知机理以及从影像分层角度分析观看立体影像时兼具宽阔的视场张角、丰富的立体层次感时所满足的条件,对红外双目立体系统合理效益条件下的各参数关系进行推导。最后根据推导结果,计算分析3种不同规格显示屏所对应的水平像素数的合理效益取值,并选择5组不同水平像素数的红外立体图像对进行实验验证。结果表明:根据推导结果搭建的红外夜视系统在让观察者获得较大视场张角的同时还兼顾效益。

In order to solve the shortcomings of the nighttime auxiliary driving plane display and obtain rich 3D layering under reasonable benefit, based on the parallel infrared binocular night vision system, the minimum resolution distance of the infrared binocular system and the human eye stereoscopic perception was analyzed. Combined with the mechanism of stereo-perception of the human eye and the condition of viewing the 3D image with large angle of view and rich 3D layering from the image hierarchy, the parameters of the infrared binocular stereo system were deduced. Finally, according to the results of the derivation, the reasonable benefit of the horizontal pixels corresponding to three different specifications display was calculated and analyzed, and five sets of infrared images with different horizontal pixels were selected for experimental verification. The results show that the infrared night vision system based on the results of the derivation not only allows the observer to obtain a larger field of view, but also takes effect.
