on the urban scene

Littered on the grass, we seemed dingy, urban riff-raff. We defiled the scene, like sardine-tins and paper bags on the seashore.(我们却好像是一堆肮脏的城市垃圾，被胡乱丢在草地上。如同海滩上的纸袋和沙丁鱼罐头盒一样败坏风景。)

This paper focuses on the post-processing algorithm of urban scene range images.(目前，对点云数据后处理算法的研究还不多。)

There are roads, traffic signs, signal lamps, vehicles and pedestrians, building and so on in the urban transport scene.(城市交通环境场景是以武汉市余家头区域的部分路网为基础，包括道路、建筑物、信号灯、车辆、行人和建筑物等。)
