spot camera 中文意思是什麼
spot camera
解釋
點片照相機-
He sprang from spot to spot fanatically with an intricate black camera.
他經常帶著一架結構復雜的黑色照相機象著了魔那樣到處奔跑。 -
In the experiment, we use the he - ne laser and the semiconductor laser as the source, record the bessel beam patterns behind the axicon by using a digital camera and a microscope, measure the radius of the bessel beam central spot by film - scanning and measure the effect of both the radius of the aperture and the open angle of the axicon on the maximum non - diffraction distance. the experiments show that a specific propagating range has constant power and the beam has a bessel - like distribution in this range. the results agree with the beam corresponding to a diffraction free beam
同時我們還採用膠片掃描的方法測量了無衍射光束的中心光斑尺寸，測量了不同光闌孔徑和不同稜角情況下的最大無衍射距離和傳播軸附近橫截面內微小光孔中的光強，實驗結果顯示當激光光束經過軸棱錐轉換後有一段距離功率變化很小，且分佈近似貝塞爾分佈，符合無衍射光束的特性;經過聚焦后，呈現三維分佈中空的光束bottlebeam ，實驗結果與理論分析基本吻合。 -
New york ( reuters ) - sales of disposable cameras, the lone bright spot in a declining traditional film market, are seen growing by 5 percent this year, albeit a slower rate than previous years as digital camera demand swells
一次性相機成了日漸走下坡路的傳統相機業的唯一亮點，在數碼相機需求與日俱增的情況下今年的銷售預計依然可增長5 % ，盡管這比去年的數字為低。 -
First, we can use a camera to take over the laser beam at one end, record the position of the light - spot, and calculate the centroid of the light - spot, then, move the laser on the guide rail. we should rectify the screw until the position of light - spot is unchangeable. then, the camera should be moved to the other end of the guide rail
先用攝像機在一端接收激光器發出的光斑，並記錄光斑的位置，求出其質心，然後在導軌上移動激光器，調節頂絲，直到攝像機上的光斑位置不動為止，然後將激光器移到導軌另一端，讓激光器在導軌上滑動，調節頂絲，直到攝像機上光斑位置不變，而且與前一次測試時的位置在誤差允許的范圍內，則認為激光器直線性校準完畢。 -
It finds extensive applications in science research, engineering design, trail analysis on the criminal investigation spot, online detection automatically, quality control, machine vision, medicine diagnosis and etc. this thesis analyzes and summarizes the domestic and international researchers ’ work about stereo vision, and then concentrates on the research on some key techniques of stereo vision, such as camera calibration, corner detection, 3 - d matching and 3 - d reconstruction
隨著科學技術和工業生產的發展，三維形面測量在現代工業及實際生產中起著越來越重要的作用，在科研、工程設計、刑事偵查現場痕跡分析、自動在線檢測、質量控制、機器視覺、醫學診斷等方面有著極其廣泛的應用前景。本文在分析和總結了當前國內外立體視覺研究工作的基礎上，針對其中的攝像機標定、角點檢測、立體匹配和三維重建四個關鍵技術部分開展研究，其主要成果如下: 1 .提出了一種改進的攝像機標定方法。 -
It is impossible to make eye contact properly, for instance, in today ' s videoconferencing systems, because the camera and the display screen cannot be in the same spot
例如說，視訊會議系統至今無法讓雙方的目光做適當的接觸，因為攝影機和顯示幕不能放在同一個點上。 -
Scanning - spot camera
光點掃瞄攝影機 -
And we also provide a detection method whose precision is on the order of micro radians. all of the above is based on technologies on ccd, dsp digital control and digital procession of images. we design a optical amplifier system matching the specified ccd camera, in order to catch qualified laser beam spot images
