Abstract: A method for map constructing, applicable for real-time mapping of a to-be-localized area provided with at least one laser device, includes taking a position of a mobile electronic as a coordinate origin of a map coordinate system, when a center of a mark projected by a first laser device coincides with central point of CCD/CMOS; moving the mobile electronic device with the coordinate origin as a starting point to traverse the entire to-be-localized area, calculating and recording coordinate values of a position of one of obstacles each time when it is detected by the mobile electronic device; and constructing a map based on recorded information of mark and corresponding coordinate values and the coordinate values of the position of each said obstacle after the traversing process is finished.

Abstract: The present invention discloses a method and an apparatus for localization and mapping based on RFID, applicable for real-time mapping of an area to be localized in which at least one RFID tag is arranged, the method comprises: taking a location of a first RFID tag as a coordinate origin of a coordinate system when information of the first RFID tag is obtained by a mobile electronic device which is moving along a certain trajectory for a first time; moving the mobile electronic device with the coordinate origin as a starting point to traverse the entire area to be localized, calculating coordinates of an obstacle based on a location of the mobile electronic device when the mobile electronic device detects the obstacle; constructing a map based on the recorded information and coordinates of the RFID tags and coordinates of each obstacle when the traversal has been finished.

Abstract: The present invention discloses a method and an apparatus for localization and mapping based on color block tags, applicable for real-time mapping of an area to be localized in which at least one color block tag is arranged, the method comprises: taking a location of a first color block tag as a coordinate origin of a coordinate system when information of the first color block tag is obtained by a mobile electronic device; moving the mobile electronic device to start to traverse the entire area to be localized from the coordinate origin, calculating coordinates of an obstacle detected by the mobile electronic device based on a location of the mobile electronic device relative to the coordinate origin; constructing a map based on recorded information of the color block tags and coordinates thereof and the coordinates of each obstacle when the traversal has been finished.

Abstract: The present invention discloses a charger, and a method, an apparatus and a system for finding charger based on map constructing, which are performed by means of: when a map for an area to be localized with a charger arranged in is constructed in real time by a mobile electronic device, the constructed map is updated based on coordinate values of a shift position of the charger when the mobile electronic device receives the coordinate values of the shift position of the charger transmitted by the charger which has shifted. Therefore, when the charger has shifted, it only needs to update the position of the charger on the constructed map without reconstructing map, which has the advantages of low cost, simple operation and effective technical results.
