Abstract

The invention discloses a multi-sensor data integration processing method and system of a minimum altitude unmanned aerial vehicle. The multi-sensor data integration processing method comprises setting initial data which comprise a GPS / IMU (Global Positioning System / Inertial Measurement Unit), basic sensor data and initial sensor installation parameters and performing post-processing on initial data based multi-sensor joint data; defining the data transfer process and interface file specification of the multi-sensor post-processing; uniformly planning and calculating multiple sensors into the joint data processing mode of the same absolute reference coordinate system through an installation error registration model with the GPS / IMU as the reference benchmark. According to the technical scheme of the multi-sensor data integration processing method and system of the minimum altitude unmanned aerial vehicle, the geometric data post-processing specific to the multiple sensors can be achieved.

Description

technical field [0001] The invention relates to the technical field of aerial surveying and mapping, in particular to an integrated processing method and system for multi-sensor data of an ultra-low-altitude unmanned aerial vehicle. Background technique [0002] The multi-sensor data integrated processing of ultra-low-altitude UAV oriented to power line inspection is a multi-sensor joint data processing technology oriented to the application of power line intelligent inspection. The key issues covered by this technology include: 1) Designing a software functional architecture that conforms to the joint data processing of four types of sensors; 2) Defining the data stream and file format specifications that the software system is compatible with; 3) Using GPS / IMU data as positioning positioning Attitude-based, the joint data processing mode of the same absolute reference coordinate system through the placement error registration model between the sensors is uniformly calculat...
