Abstract
A method for detecting objects of a specified class in an aerial image of an area, including manipulating first and second features related to each element of the image according to image metadata and pre-configured rules, selecting a first group of elements complying with a first condition related to the first feature, the first condition based on the image metadata and the pre-configured rules, selecting a second group of elements complying with a second condition related to the second feature, the second condition based on the image metadata and the pre-configured rules, and creating a representation of the area from elements common to the first group and the second group, the representation including elements belonging to the objects of the specified class.
Claims14
A method for detecting objects of a specified class in an aerial image of an area, the method comprising:
- magnifying differences between colors of pixels in an RGB raster of the image;
- changing irregular color of pixels to values of most adjacent pixels;
- magnifying differences between height of pixels in a DSM raster of the image;
- changing irregular height value of pixels to values of most adjacent pixels;
- selecting a first group of pixels complying with a first condition related to the color, the first condition based on the image metadata and the pre-configured rules;
- selecting a second group of pixels complying with a second condition related to the height, the second condition based on the image metadata and the pre-configured rules;
- and
- creating a representation of the area from pixels common to the first group and the second group, the representation thereby comprising elements belonging to the objects of the specified class.
A system for creating a graphic representation of objects of a specified class detected in aerial images of an area, the system implemented on at least one processor and memory, the system comprising:
- a metadata handler to select rules based on image metadata;
- a pre-processing module to manipulate first and second features related to each element of the image according to the selected rules;
- a first detection module to create a first group of elements complying with a first condition related to the first feature, the first condition based on the selected rules;
- a second detection module to create a second group of elements complying with a second condition related to the second feature, the second condition based on the selected rules;
- and
- a combination module to create the graphic representation containing elements common to the first group and the second group thereby creating the graphic representation of the objects of the specified class.
