摘要
为解决估计运动目标和静止观测者之间的接触时间(time-to-contact)的问题,提出利用特征线段估计接触时间的思路;由估计匀速运动目标和静止观测者接触时间的特征点跟踪方案,给出特征点选择与淘汰准则、运动分割方法、以及特征点跟踪方法.针对三套标记TTC的运动目标序列图像进行接触时间估计实验,结果令人满意.
Abstract
Time to contact (TTC) estimation problem between moving object and static observer was dealt with. A feature line based estimation scheme was proposed. And a TTC estimation system based on feature point tracking was presented. In addition, the feature point selection method, moving objects extraction, and feature point tracking scheme were given in detail. The experiments of TTC estimation for three sets of the TTC labeled image sequences were done, and the results are satisfactory.
