Fixed target marking method based on airborne android platform

The invention discloses a fixed target marking method based on an airborne android platform, and aims to solve the technical problem that the conventional fixed target marking method is low in target detection and positioning accuracy. The fixed target marking method is characterized by comprising the following steps: first, carrying out image acquisition under the premise that a mobile phone camera is demarcated; secondary, conducting binary processing on an obtained image, extracting the outline of the obtained image, matching the outline with a mold plate, and extracting the color and the coordinates of a target central circle on the obtained image if the outline of the obtained image is matched with the mold plate; removing false targets with a mobile phone direction sensor; and finally, converting the coordinates of a target image into longitude and latitude, and correcting the acquired flight data of an airplane with a mobile phone sensor. The fixed target marking method has the advantages that detects of the conventional wireless image transmitting method are overcome; and the detection and positioning accuracy of targets are improved.
