Processed Marker-Dotting Data and Analysis Code for HTC-IHE

This dataset contains the processed marker-dotting endpoint-error measurements underlying Figure 8 and Table 2 of the manuscript “HTC-IHE: An In-Hand Estimation Framework Based on Hand–Tactile Calibration for Robotic Manipulation.” The dataset includes 80 valid CAD-based measurements and 80 valid calibrated measurements. Each measurement contains the planar endpoint errors in the x and y directions relative to the fixed target point, expressed in millimetres.

The accompanying Python script reproduces the reported centroid bias, area-equivalent radii of the 90% and 80% Gaussian coverage ellipses (r90 and r80), radial-distance standard deviation, and the marker-dotting visualization. This public dataset is limited to the processed marker-dotting data and the corresponding analysis script used for Figure 8 and Table 2.
