Title: MAP CONSTRUCTION METHOD, AND CORRECTION METHOD AND APPARATUS
Abstract:
A map construction method, applicable for performing real-time map construction on an area to be positioned, wherein same is provided with at least one laser device, and comprising the steps of: using a position where a mark centre projected by a first laser device and collected by a camera on a movable electronic device and a CCD/CMOS central point coincide when the movable electronic device moves along a certain motion track the first time as a coordinate origin of a map coordinate system, and recording first mark information and a corresponding coordinate value (S11); moving the movable electronic device with the coordinate origin being a start point and traversing the entire area to be positioned (S12); during the process of traversing same, calculating and recording, based on a movement direction and a movement distance of the movable electronic device relative to the start point, a coordinate value of the position of an obstacle every time that the movable electronic device detects the obstacle (S13); and after the traversing is finished, constructing a map based on the recorded mark information and the corresponding coordinate value and the coordinate value of the position of each obstacle (S14).
