The second part of this paper deals with motion analysis which is called sfm ( structure from motion ) problem, that is, recovering the structure and motion of the object, two types of sfm algorithm are introduced - feature based and optical flow based. simulations for time to collision are done on image sequences formed by visible light and infrared image sequences. a new method called gate - average method based on the approach supposed by subbarao for the estimation of time to collision is presented
論文的第二部分討論了紅外圖象序列的運動分析，介紹了兩類運動分析的方法- - -基於特徵的方法和基於光流的方法，並對可見光圖象序列和紅外圖象序列的碰撞時間進行了模擬，並根據subbarao的方法，提出了對碰撞時間進行門限均值處理的方法。 -

The main works and results we have accomplished are as follows : 1 ) red - detuned locking of cooling / trapping laser to the cycling transition of cesium cooling has been accomplished by means of a double - passed acoustic - optical frequency shifting system and the technique of saturated absorption spectroscopy. the short - term residual frequency jitter is less than 350khz ; 2 ) automatic controlling system by computer programs has been established for laser cooling and trapping and cavity qed experiment. the laser and magnetic fields can be controlled by the acoustic - optical modulator and the electronic - controlled logic gate respectively
具體如下： 1 ）採用了往返兩次通過的聲光頻移系統結合飽和吸收光譜技術的實驗方案，實現了冷卻俘獲激光頻率相對于銫原子冷卻循環躍遷的負失諧鎖定，短期頻率穩定度約在350khz以內，並可方便地調節其負失諧量而無須對后續光路再作調整； 2 ）建立了一套基於計算機程序控制的、銫原子激光冷卻與俘獲實驗所需的時序控制系統。
