Description

technical field [0001] The invention relates to the field of robot motion modeling and parameter identification methods, in particular to the field of robot motion modeling and parameter identification methods based on airport runway detection. Background technique [0002] With the development of the modern aviation industry, the airport runway is an important platform for aircraft take-off and landing, and its safety has been paid more and more attention. Defects and foreign objects on airport runways pose a great threat to aircraft take-off and landing. Therefore, the safety detection of the airport runway is of great practical significance to ensure the smooth take-off and landing of the aircraft. It is a practical solution to use an airport runway inspection robot with omnidirectional wheels for automatic inspection, and an accurate mathematical model of system motion is very important for the autonomous motion control of the robot. [0003] The airport runway inspect...
