Strong inter-axis coupling multi-dimensional force sensor calibration method and system

The invention belongs to the related technical field of sensor calibration, and discloses a calibration method and system for a strong inter-axis coupled multi-dimensional force sensor, and the method comprises the following steps: 1, collecting a sensing signal and a corresponding force signal of a to-be-calibrated strong inter-axis coupled multi-dimensional force sensor in a whole measurement range, and obtaining a force signal of the to-be-calibrated strong inter-axis coupled multi-dimensional force sensor; carrying out filtering processing to obtain a training set; meanwhile, an FNN neural network of the to-be-calibrated strong-axis inter-coupling multi-dimensional force sensor is constructed; 2, training the FNN neural network by adopting a training set, and optimizing the FNN neural network by adopting an ant colony algorithm to obtain the optimal weight and bias of the FNN neural network; and step 3, calibrating the to-be-calibrated multi-dimensional force sensor coupled between the strong axes based o
