Abstract

The invention discloses an unmanned aerial vehicle flight log-based quantitative evaluation method, system and device, equipment and a medium. Flight log data parameters are extracted through a constructed basic data analysis platform, and then visual drawing is performed on the parameters, so that related parameters in the same classification combination are displayed in the same chart curve in acentralized manner, and synchronous operation and comparative analysis are facilitated; different methods are adopted to process and analyze sensor measurement information, attitude motion information, sensor measurement information and control system response information after classification and combination, and deep quantitative evaluation of sensor measurement noise characteristics, attitude motion frequency domain characteristics and system control quality is achieved. According to the method and the system, comparative analysis can be carried out on multiple variables, batch data processing is customized and optimized, automatic processing of key data analysis is realized, and the data analysis efficiency and the data analysis depth are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of UAV flight control, and in particular relates to an integrated depth quantitative evaluation method, system, equipment and medium based on UAV flight logs. Background technique [0002] With the increasing application of drones in military and civilian fields, the research and development of drones has become one of the focuses of the new technology industry. Due to the practical characteristics of UAV itself, test data analysis is a key link in the performance design, analysis, and verification of its research process. Through detailed analysis of UAV ground simulation or actual flight test data in the air, the performance of its trajectory planning, navigation calculation, control algorithm, etc. can be confirmed, and deficiencies can be found and improved, so as to achieve the purpose of perfecting and confirming the design status. [0003] For the flight log data format of mainstream flight controlle...
