 李偉鵬為註冊測量師



他根據郊野義務搜索隊CVST的分析資料,周二當日下午1時許,於老鼠田坑一帶利用航拍機拍攝山野15分鐘,希望能透過影像發現曾憲哲蹤影。然而由於圖片眾多而且時間有限,因此未有仔細查閲。直至昨日曾憲哲獲救後,李偉鵬再仔細查看當日於現場一帶拍攝的過千照片,猶如大海撈針般逐張逐張放大「聞相」,赫然在其中一組照片中,發現曾憲哲赤身裸體的蹤影。

土地測量師李偉鵬稱:「(今次航拍機)鏡片是有根據透視幾何,結構是散射式,所以出現斜位,所謂斜望的效果,在側面斜看見到這位人士。我在不同地方都介紹這新技術,而無人機這五至十年的普及得很快。政府和非牟利機構將來多些合作,可以利用群眾資源,市民又能幫手。」

消防處的AI分析軟件於去年底投入運作,造價約30萬元,可於5秒內分析一張航拍照片,能夠偵察人體,大約兩小時可分析逾千張相,即約1平方公里的範圍,相比起以往以肉眼分析需時8小時,大大節省約75%時間,提升搜救效率。

CMOS sensor trends and astrophotography, from amateur astronomers perspective

Nowadays, even in low light conditions, digital camera can quality pictures with higher ISO, noise and hot pixels have been gradually reduced. Sony has introduced back illumination process for consumer market. Sony BSI sensors evolved  from Exmor to now Exmor RS( stacked) technology. This stacked technology allows further chip size reduction, which has strong demands in smartphone camera market. Digital astrophotography is also benefited from such advances, utilising Back Side Illumination technology Exmor: Within the CMOS sensor, it outputs low-noise digital signals by "on-chip column AD conversion" and "dual noise reduction" to suppress noise in the first half of the process In low light conditions, when a wide aperture is desirable to collect as much light as possible. At apertures wider than f/2.0, back-illuminated Exmor R sensors are significantly more efficient at collecting light than conventional, front-illuminated sensor...

ultrafast rendezvous to ISS

    14 Oct 2020,  being the first to use a new “ultrafast” rendezvous” scheme with the ISS. Following a flawless ascent to the correct orbit, Soyuz 2 .1a , Soyuz MS-17 caught up with the orbiting laboratory in only two orbits (three hours), halving the time it takes for crew to get to the Station.   The three space travelers of the Soyuz MS-17 mission launched on a six-month mission the International Space Station.  previous 3/4 orbit rendezvous: Soyuz MS-16 4 orbit rendezvous A three-orbit profile was deemed possible without major flight design changes after inauguration of the Soyuz 2-1A rocket that provides a much higher orbit injection accuracy than its predecessors and would allow the two correction maneuvers on Orbit #2 to be eliminated while the Automated Rendezvous Phase would still remain untouched. The deletion of the Orbit #2 maneuvers was expected to slightly tighten the already restrictive phase angle window from and upper limit of 30-35° to 25-28°...
