大家覺得夜視有用嗎?

個人認為這對台灣用戶來說比較不需要,
因為台灣幾乎馬路上都有路燈,也不會有一些動物在路上穿梭(小狗小貓這些對行車安全不影響的除外)
以美國為例,晚上幾乎都是沒有路燈,連高速公路都沒有,
真的除了自己的大燈跟別人的大燈以外,啥都看不到。
然後還有許多鹿會在高速上出現,車子撞上鹿,大概不是全毀就是半毀,
所以這樣的環境真的有需要夜視裝備。

況且低照度攝影機必須在整個拍攝的範圍內光線都很弱,才會看的到東西,
如果攝影機範圍有高亮度物體,比方說車燈或路燈照到拍攝範圍內,
攝影機的曝光調整就使暗區看不見了。
所以覺得在台灣的用途不大,除非住在偏遠地區那就另當別論。

我之前自己買了一台低照度攝影機(0.1LUX)與lcd裝在車上,總共也不超過一萬元。

Deployment of AH-64s to the Balkans took place during conflicts in Bosnia and Kosovo later in the 1990s, but the Apache encountered problems which reduced their effectiveness considerably. Criticisms included a lack of training for the crews and deficiencies in night vision equipment, fuel tanks, and aircraft survivability.

美國陸軍在巴爾幹﹐科索沃﹐波士尼亞﹐波斯灣戰爭中對 AH-64A 表現上的抱怨.....包含了夜視系統的表現。

The advanced model, the AH-64D Apache Longbow, is equipped with an improved sensor suite, glass cockpit, and weapon systems。

AH-64D 升級了整個被動偵測系統 (保護夜視系統) Modernized Target Acquisition Designation Sight/PilotNight Vision Sensor (M-TADS/PNVS) ﹐ 全數位化儀表跟武器系統.......

In October 2000, the US Army selected Team Apache Systems, led by Lockheed Martin and The Boeing Company, for its Modernized Target Acquisition Designation Sight/Pilot Night Vision Sensor (M-TADS/PNVS) program. Lockheed Martin’s innovative design—Arrowhead—will provide a new electro-optical system, continuing a 20-year legacy. Production began in 2003, and by June 2005, the US Army's first Apache unit will be equipped with Arrowhead for safe flight in day, night, or adverse-weather missions. Arrowhead modules will replace TADS/PNVS™ hardware using a field retrofit kit at US Army field sites. Arrowhead improves performance and reliability by over 150%, cuts maintenance actions by nearly 60%, and reduces field maintenance to two levels—achieving a savings approaching $1 billion in US Army operation and support costs over the 20-year system life. Its design opens the growth path to dual-band laser and next generation multi-spectral arrays.

Targeting
Arrowhead’s lower turret contains the targeting system, which has both day and night sensor assemblies. The targeting forward-looking infrared (FLIR) sensor, uses SADA I technology based on the Comanche advanced FLIR. The FLIR has three fields-of-view, a multi-target tracker, multiple-code laser spot tracking, and auto-boresight. A charge-coupled device camera improves day television (TV) viewing. Arrowhead’s electro-optics will replace the TADS/PNVS direct-view optics with a new design, the TADS electronic display and control (TEDAC) unit. TEDAC’s flat-panel display improves target resolution, situational awareness, and survivable space in the crew station.

Pilotage
The Arrowhead pilotage system provides a highly improved image in the cockpit display and the pilot’s helmet-mounted display for safe nap-of-the-earth flight at night and in adverse weather. This FLIR has a SADA I integrated detector cooler assembly and four electronics modules that are common to the targeting FLIR. These modules convert detector outputs into a video signal that is displayed in the cockpit and on the helmet-mounted display, providing a day-like TV image. The new system also has an image-intensified TV camera to aid pilotage in athermal environments and urban scenarios. Moreover, Arrowhead’s advanced processing algorithms give pilots the best resolution possible to avoid such obstacles as wires and trees during low-level flight. Arrowhead also has full provisions for image fusion.

Features

* Greatly improved FLIR performance for accurate flight and fight in day, night, or adverse weather
* Apache modernization at the flightline
* Streamlined, two-level maintenance
* Line-replaceable modules simplify field maintenance
* Digital video enhances tracking and recording
* Cueing from Longbow fire control radar or radar frequency interferometer identifies targets


新的第三代 TADS/PNVS 系統﹐計劃代號“Arrowhead" 的細節﹐ 基本上跟第二代比可以提供 150% 的系統性能以及 60% 可靠度改進 (跟第一代比不知道改良了多少) 最重要的改善就是 FLIR 夜視系統的改良。

找個晚上去試車 跑淡金公路就可以知道效果了

最好是天空配合下點小雨

如果沒什麼車再以70KM/H定速方式跑跑看

淡金的路沒路燈的路段一大堆 又有一堆愛亂竄的

真的是試車的好地方!!

問題是台南這裡試車只開放白天
明早試完車如果真訂了頂級的再喬喬晚上試試好了
個人覺得這個功能非常實用也值得,沒路燈的鄉間小路很好用,

有些黑色汽車或機車晚上忘了開車燈真的會看不太到,

曲折的山路就應該沒什麼用,這時AFS才有用

螢幕應該像賓士一樣獨立在駕駛座前較安全,若是有抬頭顯示更好
看樣子大家還是沒搞清楚實際的情況
它的視角很小,官方說100公尺遠40公尺寬....也就是說看到100公尺距離時可以看到40公尺的寬度.你知道看20公尺距離時...能看多寬的距離嗎??答案是8公尺
在這麼小的視角,你是不可能用它來開車的,因為越近你看到的範圍越小,兩旁視線外的東西根本看不到,若路上左右兩邊有來車,當你看到已經來不及反應了....
再則,螢幕不是在你的正前方你必須低頭側看...看螢幕你就不能看前方,這樣開車更危險
所以它只是噱頭,根本沒有實用價值
(連示範的影片駕駛都是低著頭看螢幕,真是錯誤的示範啊)
我想有點駕駛經驗的都知道,這東西絕對拿來輔助用的,當天候不佳的時候,真的是非常好用,覺得實用性不高的人,我覺得這東西本來就是用來防止問題產生,當然問題的發生不是隨時都有,就如同氣囊不是沒事幹就拿出來爆是一樣的道理。

同意這是拿來輔助用,但是要如何輔助?在視線不佳時,眼睛盯著前方看都來不及了你還可以分心看螢幕??
這低頭測看的幾秒內就已經相當危險了.
若真的要拿來輔助,請投射到前檔上,讓駕駛看前方時同時可以看到night vision的影像再來說吧....
否則,這樣的設計,只能說是噱頭十足,實用性沒有
Bimmer也是在中間阿,Merc在儀錶板真的很不賴。

我這輩子碰過兩次,車速都得降到5km。
一次在陽明山大霧,還好是白天,慢慢開還可以看到線。
一次在滿月圓,晚上大霧,什麼都看不到,其中有一段中線還不見,學弟開到前輪接近山崖才發現。

這種時候就派上用場了。看著螢幕慢慢嚕當作打電動就對了。
