Abstract: A micro-probe laser frequency modulation interferometric ranging method and system, under the premise of not introducing an absolute laser rangefinder to introduce new uncertainties, continuously and slowly changes the modulated laser wavelength, resulting in a continuous periodic phase change in the interference signal obtained by the detector. The laser modulation absorption spectrum shifts from the initial locked absorption peak to another locked peak, and the wavelength changes of the two locked absorption peaks before and after are obtained by checking the table. Meanwhile, calculating the phase difference demodulated by the phase generated carrier (PGC) before and after, and the initial length of optical dead-path is calculated using wavelength scanning technology. Afterwards, utilizing the advantages of high relative distance measurement accuracy of micro-probe fiber optic laser interferometer, real-time measurement of the measured distance is achieved.

The visual features determined from such images are compared to the visual map. Positions of one or more of the map points are identified as most likely corresponding to a position of the autonomous ground vehicle where visual features associated with such map points are similar to the visual features determined from such images.
