Automatic Registration of Aerial Image and Digital Map for Detection of Earthquake Damaged Areas
نویسندگان
چکیده
In this paper, we propose an automatic detection method of the areas damaged by an earthquake. We use aerial images that are taken before and after the earthquake. To detect the damaged areas, we register these two aerial images. It is difficult to register two aerial images by using only the image information, and hence, we use digital map for registering them. First each aerial image is registered to the digital map by using the perspective transformation. Then we detect damaged areas by computing the differences between the registered images. The damaged areas can be detected automatically and correctly by our method.

Automatic identification and localization of cartographic objects in aerial and satellite images have gained increasing attention in recent years in digital photogrammetry and remote sensing. Although the automatic extraction of man made objects in essence is still an unresolved issue, the man made objects can be extracted from aerial photos and satellite images. Recently, the high-resolution s...

After an earthquake, the image-based interpretation methods are powerful tools for detection and classification of damaged buildings. A method based on two kinds of image-extracted features comparing stereo pairs of aerial images before and after an earthquake is presented. Comparing preand post event DSMs generated from stereo images could be a solution for detecting the extent of demolished a...

متن کاملReducing Light Change Effects in Automatic Road Detection
Automatic road extraction from aerial images can be very helpful in traffic control and vehicle guidance systems. Most of the road detection approaches are based on image segmentation algorithms. Color-based segmentation is very sensitive to light changes and consequently the change of weather condition affects the recognition rate of road detection systems. In order to reduce the light change ...
