By altering the height with a fixed increment, the path intersects the curves of the contour to arrive at the terminal point. 通过已确定的增量变化高度,路径得以穿越各条等高线到达终点。
Because of the arithmetic having considered the annotation width and the degree of curvature of curve, the distribution of height annotation more even, the arrangement more order and the amount more mezzo of contour. 由于该算法同时考虑了注记宽度和曲线的弯曲度,因而与其他算法相比,等高线高程自动注记分布均匀合理,排列整齐,数量适中。
A new algorism of automatically-labeling contour height in contour graph is put forward in the paper, because the algorism focuses on whole structure and shape of the contour, the arrangement of height label is more orderly and its distribution is more harmonious compared to other algorisms 文中提出了一种新的等高线图等高线高程自动注记算法,由于该算法着眼于等高线的整体结构形态,因而与其余算法相比,等高线高程注记排列较为整齐、分布较为协调
In one word, ideas of this paper were to apply the height value of LIDAR data and the contour information of the house in the aerial. 总的来说,本论文的思想是利用Lidar数据的高程信息和航空影像房屋的轮廓信息,二者相辅相成,取长补短。
