摘要： The present disclosure provides a map optimization method, an apparatus, an electronic device and a storage medium. Here, the map optimization method includes: obtaining an original map, the original map including an explore zone, a covered zone, an obstacle zone; determining and deleting an error zone from the explore zone in view of the covered zone and the obstacle zone. According to the technical solution of the present disclosure, in view of points in zones of different properties in the original map, and the localization principle, an error zone is determined and deleted from the original map, thereby realizing the optimization of the original map, such that the optimized map is closer to the actual map. This enables the autonomous mobile device to execute tasks more efficiently based on the optimized map.

摘要： 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.
