Embodiment Construction

[0034] The application will be described in further detail below in conjunction with the accompanying drawings.

[0035] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe operations as sequential processing, many of the operations may be performed in parallel, concurrently, or simultaneously. In addition, the order of operations can be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not included in the figure. The processing may correspond to a method, function, procedure, subroutine, subroutine, or the like.

[0036] The term "computer equipment" in this context, also referred to as "computer", refers to an intelligent electronic device that can perform predetermined processing procedures such as numerical calculations and / or logic calculations by running...

Abstract

The invention provides a method and a system for generating an indoor map. The generation method comprises steps: an indoor way area image is extracted from an acquired indoor electronic base map; the indoor way area image is subjected to mathematical morphology expansion and corrosion to obtain a skeleton bitmap corresponding to the indoor way area image; and the skeleton bitmap is vectorized to obtain an indoor map. The embodiment of the invention can generate the indoor electronic map conveniently, practically and quickly.

Description

technical field [0001] The present application relates to the technical field of geographic information, in particular to a method and system for generating an indoor map. Background technique [0002] As the basis of indoor navigation, indoor maps are currently generated mainly through manual drawing. Generally, indoor basemaps of buildings (such as figure 1 As shown, including the floors represented by the plane and the functional areas such as shops, toilets, and elevators drawn on the plane), and based on the positional relationship between the floors and the functional areas, subjectively judge the passable areas of each floor (such as passageways) ), so as to manually draw the edges and nodes of the traversable roads (such as the intersection of two roads), and present them in the indoor map. [0003] Due to the high labor cost and long drawing cycle of manual drawing, once the internal structure of the building changes, the previously drawn indoor map cannot be quic...
