I climbed onto the roof to install an aerial and was seen by a neighbor, who reported seeing a burglar on the prowl.
那時候我爬到屋頂上安裝一根天線，這個情況被一個鄰居看到了，他向警察報告說他看到一個小偷在那裡探頭探腦。 -
A method for extracting building roof region is presented, which is based on fitting ground points of vertical lines f rom multiple aerial images
另外，還針對屋頂灰度變化較均勻的建築物，研究和提出了一種基於多幅圖像垂直邊緣地面點坐標擬合的建築物屋頂區域提取方法。 -
Based on the extracted vertical edges, a method for roof boundary extraction in monocular aerial images using line snakes model is proposed. in addition, to detect buildings which have smooth gray - value in roof.,
根據垂直邊緣這一建築物的一般特徵，提出了一種基於單幅影像的直線snakes （又名主動輪廓， activecontours ）建築物輪廓跟蹤方法。 -
The improvement on the process of automatically measuring city buildings is one of the most important problems in the current aerial photographic measurement. an approach to measuring a city building based on its structure information is presented. a city building ' s ideal model is first represented by some independent parameters according to its structure information and some image variants which can induce model parameters are defined, and then the initial value of image variants are acquired by combining all kinds of information in the left and right images. finally the optimal location of the building is found for some certain criteria. an implementation of this method is illustrated on flat - roof and rectangular buildings in detail. the experimental results show that not only the method is more automatic than existing methods but also the precision of measurement can satisfy the acquirement of the current aerial photographic measurement, and confirm the method has a good developmental and applied potential
提高城市建築物測量過程的自動化程度是目前航空攝影測量研究的主要問題之一.文中提出了一種基於結構信息的城市建築物測量方法.首先根據城市建築物的結構信息，用幾個相互獨立的參數來描述建築物的理想模型，並定義能推導出模型參數的圖像變量，然後組合利用左右圖像中各種信息獲得圖像變量的初始值，最後在一定準則下尋求城市建築物的最佳測量位置.該文以平頂矩形建築物為例詳細討論了它的一種實現演算法.實驗結果表明，這種方法與傳統方法相比較，有較高的自動化程度，且測量精度能滿足現有航空攝影測量的要求，有較大的發展和應用潛力
