A height - gradient - based obstacle detection algorithm is proposed to process the height images outputted by stereo vision . the obstacles in scenes can be detected exactly and quickly in this way 立体视觉算法通常输出的是高度图,本文提出了一种基于高度梯度的障碍检测算法,能有效且快速的检测出场景中的障碍。
The results show that the strong winter monsoon will decrease the gradient of ssh , and change the characteristics of sst , which has influence on the sea current , especially in a shallow and closed sea area such as the south china sea 结果表明:强冬季风会减弱海面高度梯度,普遍降低黑潮区海表温度,对流场有一定的影响,尤其在南海这样的封闭海区。
