AERIAL IMAGE SEGMENTATION FOR REFINERIES

摘要

A system receives a two-dimensional digital image of an aerial industrial plant area. Based on requirements of image processing, the image is zoomed in to different sub-images, that are referred to as first images. The system identifies circular tanks, vegetation areas, process areas, and buildings in the first image. The system formulates a second digital image by concatenating the first images. The system creates one or more polygons of the regions segmented in the second digital image. Each polygon encompasses a tank area, a vegetation area, a process area, or a building area in the second digital image, which is a concatenated image of the individual regions. The system displays the second digital image on a computer display device.

1. A system comprising:
a computer processor configured to:
receive a two dimensional aerial digital image of an area;identify one or more circular tanks in the area;identify one or more vegetation areas in the area using color information in the digital image;identify one or more process areas using edge patterns;identify one or more remaining areas as building areas;concatenate the one or more tank areas, the one or more vegetation areas, the one or more process areas, and the one or more building areas to form a second digital image;create one or more polygons, each polygon encompassing a tank area, a vegetation area, a process area, or a building area in the second digital image; anddisplay the second digital image on a computer display device.
