Abstract
The present invention relates to a method and an apparatus for continuously detecting a hazardous and noxious substance from multiple satellites, and specifically, provides a method and an apparatus for continuously detecting a hazardous and noxious substance from multiple satellites, the method and apparatus: receiving a multi-satellite image which is photographed by a multi-satellite comprising a satellite having an imaging radar (SAR), a satellite having an infrared sensor, and a satellite having an electronic optical sensor; acquiring a reference image, of the satellite having the SAR, including a ground control point of an observed region; extracting a corresponding point between the reference image and the multi-satellite image; implementing the image matching and geometric correction for the multi-satellite image by using the extracted corresponding point; confirming at least one among the brightness value of pixels of the SAR satellite image, the temperature value of pixels of the infrared satellite image or the color value of pixels of the optical satellite image which are included in the corrected multi-satellite image so as to detect the hazardous and noxious substance, and determine the flow information, thereby detecting continuously and stably the hazardous and noxious substance.
