Unmanned-aerial-vehicle (UAV) flight trajectory reconstruction method based on parsing flight log files

Abstract

The invention discloses an unmanned-aerial-vehicle (UAV) flight trajectory reconstruction method based on parsing flight log files. The method includes the following steps: selecting an unmanned aerial vehicle; extracting data, wherein the data stored in the unmanned aerial vehicle are accessed by a user through any manner of three interfaces of telnet, ftp and mini-USB; recording a flight trajectory by the .pud files; wherein flight data are recorded by the .pud files, and each .pud file is divided into a head meta-information area and a flight data area; parsing the head meta-information area according to a JSON format when the stored .pud files are read, and extracting details_headers field information; identifying a flight data storage template described in the above-mentioned fields;and then parsing the flight data area according to the identified template, and extracting trajectory points. The method has the advantage that the unmanned-aerial-vehicle flight trajectory reconstruction method based on parsing the flight log files is provided for the problem that current unmanned-aerial-vehicle ''illegal-flight events'' occur frequently, but carrying out investigation and evidence collection on the same is relatively difficult.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a method for reconstructing the flight trajectory of an unmanned aerial vehicle based on parsing flight log files. Background technique [0002] Unmanned Aerial Vehicles (Umanned aerial vehicles, UAV) are aerial robots, which can replace humans to complete aerial operations, and can expand application scenarios by combining with imaging equipment and other components. In recent years, drones have been widely used in aerial photography, agriculture, forestry, security, electric power and other fields. With the maturity of technology and the reduction of spare parts costs, the market of small civilian drones dominated by multi-rotor drones has become a hot spot. On September 8, 2016, iiMedia Research, a third-party data mining and analysis organization for the global mobile Internet, released the "2016 China UAV Industry Research Report" and stated that the market size of m...

Problems solved by technology

However, the DJI UAV system is closed, and users can only access the multimedia information captured by it through the USB interface, and cannot view the flight trajectory data stored in the fuselage.

DJI Go, the mobile terminal control software of DJI, records the flight data of the aircraft, but obtaining data from the mobile APP belongs to the category of mobile phone forensics, which is not within the scope of this invention

Furthermore, when illegal aerial photography is discovered, criminal suspects often choose to simply abandon the drone at the scene rather than discarding the drone along with the cell phone that controlled it
