【摘要】：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。
[Abstract]:In order to solve the malpractice of the plane display of the nocturnal auxiliary driver and obtain a rich stereo sense under reasonable benefit, the paper analyzes and compares the minimum discernable distance between the infrared binocular system and the stereoscopic perception of human eyes from the parallel infrared binocular night vision system, and combines the stereoscopic perception mechanism of the human eye and the image stratification angle. When viewing the stereoscopic images with wide field of view angle and rich stereoscopic level, the relationship between the parameters under the reasonable benefit of infrared binocular stereo system is deduced. Finally, according to the derivation results, the reasonable value of the horizontal pixel number corresponding to the 3 different sizes of display screens is calculated and analyzed, and 5 is selected. The infrared stereoscopic images of different level pixels were tested. The results showed that the infrared night vision system built on the basis of the derivation gave the observer a large angle of view and also gave consideration to the benefit.
