Abstract
The present disclosure provides a method and a device for determining a motion parameter of an autonomous mobile device. The method includes: an anti-fall sensor detects a current chassis-floor distance between a chassis of the autonomous mobile device and a current floor, and transmits the current chassis-floor distance to a processor; the processor determines a correction coefficient corresponding to the current chassis-floor distance; the processor obtains an output of an optic flow sensor; the processor determines the motion parameter corresponding to the current chassis-floor distance based on a correction coefficient, a calibration coefficient, and the output of the optic flow sensor, which increases the accuracy of the motion parameter obtained through computation.
