【摘要】：為解決當(dāng)前夜間輔助駕駛儀平面顯示的弊端以及在合理效益下獲得豐富的立體層次感,文中從平行式紅外雙目夜視系統(tǒng)出發(fā)分析對(duì)比了紅外雙目系統(tǒng)和人眼立體感知的最小可分辨距離,結(jié)合人眼立體感知機(jī)理以及從影像分層角度分析觀看立體影像時(shí)兼具寬闊的視場(chǎng)張角、豐富的立體層次感時(shí)所滿足的條件,對(duì)紅外雙目立體系統(tǒng)合理效益條件下的各參數(shù)關(guān)系進(jìn)行推導(dǎo)。最后根據(jù)推導(dǎo)結(jié)果,計(jì)算分析3種不同規(guī)格顯示屏所對(duì)應(yīng)的水平像素?cái)?shù)的合理效益取值,并選擇5組不同水平像素?cái)?shù)的紅外立體圖像對(duì)進(jìn)行實(shí)驗(yàn)驗(yàn)證。結(jié)果表明:根據(jù)推導(dǎo)結(jié)果搭建的紅外夜視系統(tǒng)在讓觀察者獲得較大視場(chǎng)張角的同時(shí)還兼顧效益。
[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.
