1. The main function of the special area is to perform special algorithm processing on some
areas with relatively simple feature points (such as long corridors) or areas with relatively
few feature points (such as empty halls).
2. Before drawing a special area, it is recommended to navigate to each area to see if there
is a loss of positioning, and draw a special area as needed.
3. After saving the drawing, click "Navigation Mode" to return to the navigation mode.
