    摘要: A system and method including, predicting a first set of Doppler velocity information for a first point set to produce a first predicted set of Doppler velocity information for the first point set; determining one or more Doppler velocity errors based on the first predicted set of Doppler velocity information and a second set of Doppler velocity information; predicting a third set of Doppler velocity information for the second point set to produce a second predicted set of Doppler velocity information for the second point set; determining one or more Doppler velocity errors based on at least one of the second predicted set of Doppler velocity information and a fourth set of Doppler velocity information; and producing a transform that aligns the one or more points of the first point set with the one or more points of the second point set.

    摘要: A system and method including, predicting, using a sensor system, a first set of Doppler velocity information for a first point set to produce a first predicted set of Doppler velocity information for the first point set. The method includes determining one or more Doppler velocity errors based on the first predicted set of Doppler velocity information and a second set of Doppler velocity information measured for one or more points of the first point set. The method includes producing, in view of the one or more Doppler velocity errors, a transform that aligns the one or more points of the first point set with one or more points of a second point set to produce one or more scan frames.

    摘要: A system and method including, determining an alignment between one or more points of a first point set and one or more points of a second point set; predicting a first set of Doppler velocity information for the first point set to produce a first predicted set of Doppler velocity information; comparing a second set of Doppler velocity information and the first predicted set of Doppler velocity information to compute one or more Doppler velocity errors; predicting a third set of Doppler velocity information for the second point set to produce a second predicted set of Doppler velocity information; comparing a fourth set of Doppler velocity information and the second predicted set of Doppler velocity information to compute Doppler velocity errors; and producing a transform that aligns the one or more points of the first point set with the one or more points of the second point set.

    摘要: A system and method including, determining an alignment between one or more points of a first point set and one or more points of a second point set; provided the alignment does not satisfy a point set alignment threshold, wherein the point set alignment threshold represents a geometric alignment error threshold between the first and second point sets: predicting a first set of Doppler velocity information for the first point set to produce a first predicted set of Doppler velocity information for the first point set; comparing a second set of Doppler velocity information and the first predicted set of Doppler velocity information to compute one or more Doppler velocity errors; and producing a transform that aligns the one or more points of the first point set with the one or more points of the second point set to produce a globally consistent registered point set.
