Embodiment 1
[0047] See figure 1 as shown, figure 1 Shown is a positioning method for a mobile electronic device, including:
[0048] Step S11. Obtain an area map of the location of the mobile electronic device, the area map includes a plurality of poses, each of the plurality of poses corresponds to a set of feature points;
[0049] Wherein, the area map is the map corresponding to the location of the mobile electronic device, and the area map is known and can be obtained in advance. We know what the environment in the area map is like, for example, the area map Shown is a rectangular office, the area map can show the layout of the office, and can understand which places in the office are vacant and which places are obstacles. Movable electronic devices are usually moved on open spaces in the office and cannot pass through obstacles.
[0050]Moreover, the area map includes many poses, each of which corresponds to a set of feature points. For example, these poses are all distributed on ...
Embodiment 2
[0066] See figure 2 as shown, figure 2 What is shown is another positioning method for a mobile electronic device, including:
[0067] Step S21. Obtain an area map of the location of the mobile electronic device, the area map includes a plurality of poses, and each pose in the plurality of poses corresponds to a set of feature points;
[0068] Wherein, the area map is the map corresponding to the location of the mobile electronic device, and the area map is known and can be obtained in advance. We know what the environment in the area map is like, for example, the area map It shows a rectangular office, and the map of the area can show the layout of the office, and can understand which places in the office are vacant and which places are obstacles. Movable electronic devices are usually moved on open spaces in the office and cannot pass through obstacles.
[0069] Moreover, the area map includes many poses, each of which corresponds to a set of feature points. For example...
Embodiment 3
[0093] See image 3 as shown, image 3 What is shown is a mobile electronic device, including: an acquisition module 11, configured to acquire an area map of the location of the mobile electronic device, the area map includes a plurality of poses, and the positions in the plurality of poses are Each pose corresponds to a set of feature points; the first extraction module 12 is configured to extract at least one pose in the area map and the first corresponding to each pose in the at least one pose Feature point set; the second extraction module 13 is used to extract a second feature point set from the observation information currently scanned by the mobile electronic device; the first identification module 14 is used to combine with the second feature point set The first feature point set whose matching degree is greater than the preset value is used as the third feature point set; the second identification module 15 is used to use the same feature points in the second feature...
