Embodiment

[0057] figure 2 Shown is the block diagram of the circuit structure of the positioning device of the present invention, which includes a polygon generation unit 1, a measurement position unit 2, a ray generation unit 3, an intersection detection unit 4, a winding number calculation unit 5 and a storage unit 6.

[0058] Wherein the polygon generation unit 1 described in this embodiment reads in the map data and generates such as figure 1 The shown polygonal vertex sequence Array (V0V1V2V3V4V5V6V7V8V0) and a boundary vector group Vector_Group[V0V1, V1V2, V2V3, V3V4, V4V5, V5V6, V6V7, V7V8, V8V0] formed by the vertex sequence.

[0059] The position measurement unit 2 measures and reads the position data of the measured object, that is, determines the positional relationship between the measured object and the polygon.

[0060] The ray generating unit 3 generates a ray in any direction from the position of the measured object within the plane formed by the polygon. Such as fi...

Abstract

The invention discloses a positioning device and a positioning method thereof. The positioning device comprises a polygon generation unit for reading map data and generating a peak sequence of polygons and a boundary vector group consisting of the peak sequence, a position measurement unit for measuring and reading position data of a measured object, a ray generation unit for generating a ray in a plane consisting of the polygons from the position of the measured object to any direction, an intersection detection unit for detecting whether a boundary vector in the boundary vector group is intersected with the ray and a winding number calculation unit for detecting whether the position of the measured object is in the clockwise direction or the anticlockwise direction of a direction of the boundary vector intersected with the ray and correspondingly decreasing or increasing the winding number. By the positioning device and the positioning method thereof, the operation efficiency of the positioning efficiency is improved, the reaction speed of the positioning device is increased, and the energy loss is effectively reduced.

Description

technical field [0001] The invention relates to a positioning device and a positioning method thereof, in particular to a positioning device suitable for area monitoring and a positioning method thereof. Background technique [0002] The positioning device is a combination of global satellite positioning GPS technology, modern global mobile communication system GSM technology, geographic information system GIS technology, WEB technology and computer communication technology, and the dynamic position (longitude, latitude, etc.) ), time, status and other information are transmitted to the monitoring center through the GSM wireless communication network in real time, and then the trajectory of the moving target is displayed on the electronic map with complete information, and the parameters such as the position, speed, direction of movement, and monitoring target status of the target are displayed. Monitor and query. [0003] Since the monitored object is often restricted to m...
