The dissertation is mainly including four section : the first is the experiments done in the tank, which will supply the reliable information of imaging data ; the second is image edge detection by the use of the art of the zernkie moments, which is used to detect the liner and threaded edge of the object, the third is the underwater camera calibration technique, the forth is automatic positioning the location of the camera by used of the art of cross - ratio, the result of which is satisfied
本文工作分為四個部分:第一部分是水槽實驗部分,它為后續的工作提供了可靠的圖像數據信息;第二部分是基於zom距的直線、曲線邊緣提取技術及相關的與處理技術;第三部分,水下攝像機標定技術研究,基於改進的tsai演算法,採用逐步分解的標定策略。並探討了一種相對簡單的、靈活的標定技術;第四部分是攝像機定位技術研究,採用具有平移不變性的交比進行攝像機定位,模擬試驗的最大誤差不超過2 ,效果還是令人滿意的。The main task of this paper concentrates on such parts as calibration of measurement sensor, high speed and accuracy image collection and processing, data fusion of different angle of view, visualization of measuring results. to accomplish sensor calibration, a pinhole model of the camera is employed and an equation of a light plane is setup. parameters such as the m array of the pinhole model and the normal vector of the light plane arc acquired through experiment. in image processing, we adopt the template - changing parallel thinning method to improve processing speed and accuracy
主要研究了攝像機針孔模型的建立及測量傳感器的標定;圖像的快速高精度的採集和處理,在圖像處理中採用多幀平均演算法,很好地解決了速度和精度之間的矛盾制約;根據旋動理論建立空間坐標變換數學模型,進而建立其不同視角下的測量數據融合演算法,生成完整的物體三維數據集合;在vc平臺下編寫三維顯示軟體模塊,完成三維測量結果的可視化,實現了三維物體的任意角度的觀察、任意倍數的放大和縮小、任意方向平移及動畫效果。Because of the surveillance - area of the vidicon, the system will lost the target if it moves out the area in the case of nobody on duty
在無人值守監測到異物入侵的情況下,由於攝像機拍攝到的范圍有限,若異物移動至可視范圍外時,系統將失去目標。As we know, gloal motion caused by camera vibration is quite common in image sequence. this nuisance factor resukts in translational, totational and parallax distortions in images
很多情況下攝像機安裝在運動平臺上,由於由攝像機顫動引起的全局運動是在圖像序列中普遍存在的,這個因素在圖像中將產生平移,旋轉以及視差畸變等後果。Once you ' re sure you have your camera matched, freeze it in max to avoid accidentally shifting it whilst you continue to work on the scene
一旦你對齊了攝像機,在max中鎖定它,以避免在下面的工作中不小心被移動。In this instance, the location of camera in the world coordinates is unnecessary to calibrated, and the rotary matrix and horizontal movable matrix is needless too
這種情況下不需要標定攝像機在世界坐標系的位置,相對的對於世界坐標系的旋轉矩陣和平移矩陣也不需要。The precondition of global localization is to have a map of current environment. the robot with stereo vision system can get the 3d information of the environment without moving, and the precision of the 3d information is satisfied. however, the robot who only uses single camera as its sensor has to move for a distance to obtain the 3d information of environment
全局定位的前提是要有一個環境地圖,裝有立體視覺攝像機的機器人在不移動的情況下就能獲得環境的三維信息,並且三維信息的精度較高,而利用單個攝像機創建地圖必須通過機器人的移動才能獲得環境的三維信息,這種通過運動重構周圍環境的過程稱為基於運動的重建( structurefrommotion ) 。分享友人
