Abstract
A system and method for classifying vehicles from laser scan data by receiving laser scan data corresponding to multiple vehicles from a laser scanner; extracting vehicle shapes corresponding to the multiple vehicles based on the laser scan data; aligning the vehicle shapes; and generating vehicle profiles based on the aligned vehicle shapes. The system and method can further include aligning the vehicle shapes using sequence kernels, such as global alignment kernels, and constraining the sequence kernels based on determined weights.
Claims18
A method for classifying vehicles comprising:
- receiving laser scan data corresponding to a plurality of vehicles;
- extracting, based on the laser scan data, a plurality of vehicle shapes corresponding to the plurality of vehicles;
- aligning the plurality of vehicle shapes to generate a plurality of aligned vehicle shapes, wherein aligning the plurality of vehicle shapes comprises aligning the plurality of vehicle shapes using sequence kernels;
- and
- generating one or more vehicle profiles based on the aligned vehicle shapes.
A system for classifying vehicles comprising:
- a processing system comprising one or more processors;
- and
- a memory system comprising one or more computer-readable media, wherein the one or more computer-readable media contain instructions that, when executed by the processing system, cause the processing system to perform operations comprising:
- receiving laser scan data corresponding to a plurality of vehicles;
- extracting, based on the laser scan data, a plurality of vehicle shapes corresponding to the plurality of vehicles;
- aligning the plurality of vehicle shapes to generate a plurality of aligned vehicle shapes, wherein aligning the plurality of vehicle shapes comprises aligning the plurality of vehicle shapes using sequence kernels;
- and
- generating one or more vehicle profiles based on the aligned vehicle shapes.
