天文學家分析8.17南京飛碟視頻造假作品
新浪科技訊 8月22日新浪科技刊出《天文專家認為8.17南京飛碟視頻不可信》的 報道后，引起公眾的不小反響，江蘇省天文學會專家在會商分析后 認為，該段視頻是造假作品，在評論系統里不少網友譴責該惡作劇 的始作俑者。 江蘇省天文學會專家在會商后認為，從外表上看，這個飛行器的外 觀的確有些像“飛碟”，但是飛碟一般都是金屬外殼，而17日17點 23分南京的太陽還在較高的地平高度，按理說在太陽光照射下，金 屬物體都會發光，可是該飛行器上并沒有顯現出金屬特有的光澤。 此外，從事計算機軟件開發的專家將視頻作連續截圖，用作單幀分 析，發現明顯漏洞。第一，角度有問題，拍攝者是傾斜65度左右拍 攝的，怎么能看到對側邊緣的光源呢？第二，亮燈時候是光源在四 側的話怎么沒有透視關系呢？而光源都是几個90度面對觀眾的圓點 點呢？(見圖) 判斷出“飛碟”亮燈的前一幀，和亮燈時的一幀做比較，發現飛碟 的上下位置有少許偏移(從右上到左下)，而周圍的房屋卻沒有移動 ，而之后和之前的每一幀，所有圖像都是動的。這是最大的破綻。 實際上是把亮燈之前的那一幀用軟件修正上去的。(馬偉宏)
Hypotheses
Mounting
Photo editing began to be used almost immediately after the advent of photography techniques. They were divided into methods of photomontage without manipulation of the image after receiving the photo and retouching of the photo itself or its negative (plate, film, etc.)
Investigation
On August 22, Sina Science and Technology published an article "Astronomy experts believe that the 8.17 UFO video in Nanjing is not trustworthy."
Specialists involved in the development of computer software make continuous screenshots of videos for frame-by-frame analysis. the analysis also found obvious loopholes.
Firstly, there is a problem with the angle, the photo is tilted at about 65 degrees to shoot. How can I see the light source on the opposite edge?
Secondly, when the light is on, the light source is at four points. Why are there no promising relationships if they are lateral? And the light source is several points facing the audience at an angle of 90 degrees. what point?
Look at the frame before the "flying saucer" lights up, and compare it with the frame with the light on, and find the flying saucer. The upper and lower positions are slightly shifted (from top right to bottom left), and the surrounding houses do not move, and every frame after and before, all images move. This is the biggest drawback.
In fact, the frame is adjusted programmatically before the appearance of lighting. (Ma Weihong)
