Abstract
A computer-implemented method for aligning a sensor to a vehicle includes receiving a first frame of measurement from the sensor which includes a first point cloud. One or more clusters Crepresenting one or more objects or the ground are segmented. A first set of feature vectors fis computed for each cluster C. Based on the first set of feature vectors fa second set of feature vectors f' is predicted respectively using an initial transformation. A third set of feature vectors fis computed for a second frame with a second point cloud with clusters C. A pair of matching clusters is identified from Cand C. A feature distance between the matching clusters is computed. An alignment transformation is computed by updating the initial transformation based on the feature distance. The method further includes aligning the sensor and the vehicle based on the alignment transformation.
