Embodiment
[0084] This embodiment uses the scenic spot data of a certain lake scenic spot in city A to conduct the experiment.
[0085]For the obtained raw data, a geo-fence is first constructed. Since the geo-fences of scenic spots have different shapes, the minimum outer rectangle MBR (Minimal Bounding Rectangle) is used to approximate the geo-fence of scenic spots. like image 3 , the geo-fence of scenic area A is approximately represented by rectangle B. A: Indicates the shape of the scenic spot (arbitrary polygon), B: Indicates the smallest enclosing rectangle of A.
[0086] Second, build a virtual fence as follows:
[0087] The first step is to enclose the geo-fenced area of the scenic spot with a minimum enclosing rectangle (MBR (Minimal Bounding Rectangle). For example, Scenic Spot A is surrounded by the smallest enclosing rectangle B. These rectangles will be stored in the leaf nodes of the R tree. image 3 shown.
[0088] The second step is to frame the adjacent smallest ...
