To develop a framework for simultaneous localization and mapping that addresses sensor disturbances in agricultural settings.
Constructed a curved-voxel-based intensity-geometry joint probability model for spatial feature extraction.
Minimized joint probability distance for feature alignment using normal distributions transform.
Designed a maximum a posteriori-based recursive noise estimator with dual sub-filter architecture.
Achieved a mean relative translation error of 1.42% and a mean relative rotation error of 1.53°/100 m.
Constrained average error in row spacing estimation to within 0.071 m.
Demonstrated significant improvement in pose estimation accuracy compared to baseline methods.
