Section is y=((y2-y1)/(x2-x1)) x, min (x1, x2)≤x≤max(x1, x2))。
Fig. 6 is the schematic diagram determining position relationship.As shown in Figure 6, Article 1 border corresponding two
End points is P1And P2, two end points corresponding to Article 2 border are P2And P3, the N article border is corresponding
Two end points are PnAnd P1Deng.
Step 505, the relation determined between ray and the line segment determined, between ray and line segment
Relation be from or parallel time, after M is added 1 perform step 503；Relation between ray and line segment
For time crossing, perform step 506；When relation between ray and line segment is for being stacked, perform step 510.
In this step, between ray and line segment, have 4 kinds of relations: be stacked, parallel, crossing and from.Example
As, as M=1, if x1=x2=x0And y0≤max(y1,y2), then the relation between ray and line segment is
It is stacked；If x1=x2≠x0, then the relation between ray and line segment is parallel, if x1≠x2And y0≤
((y2-y1)/(x2-x1))x0, then the relation between ray and line segment is crossing；Remaining is then between ray and line segment
Relation be from.
When step 506, intersection point is line segment end points between ray and line segment, perform step 507,
Otherwise perform step 509.
Such as, as M=1, the intersection point between ray and line segment is C (x0,((y2-y1)/(x2-x1))x0), point
C and line segment have 3 kinds of position relationships, i.e. some C and some P1Overlap, put C and some P2Overlap, some C exists
Point P1、P2Between.
Step 507, when another of another end points of line segment and another border with intersection point as end points
When end points is positioned at the both sides of ray, perform step 508；When another end points of line segment with intersection point for end
When another end points on another border of point is not positioned at the both sides of ray, after M is added 1, perform step
503。
Such as, as M=1, if intersection point C and some P1Overlap, then line segment PnP1And ray intersection,
If some P2With a PnBe distributed in ray both sides, then joining counter adds 1.
If intersection point C and P2Point overlaps, then line segment P2P3And ray intersection, perform after M is added 1
Step 503.
If before step 508 intersection point comes another end points of line segment, then intersection point counter being added 1,
And after M is added 1, perform step 503；If after intersection point comes another end points of line segment, then by M
Step 503 is performed after adding 1.
Step 509, intersection point counter is added 1, and perform step 503 after M is added 1.
If two borders that step 510 is adjacent with line segment are positioned at the both sides of line segment, then intersection point is counted
Device adds 1, and performs step 503 after adding 2 by M；If adjacent with line segment two border is not positioned at line
The both sides of section, then perform step 503 after adding 2 by M.
Such as, as line segment PnP1When being stacked with ray, if some P2With a Pn-1It is distributed in ray both sides, then
Intersection point counter is added 1, and performs step 503 after M is added 2；As line segment P2P3When being stacked with ray,
If some P1、P4It is distributed in ray both sides, then intersection point counter is added 1, and perform step after M is added 2
503。
Step 511, when intersection point counter is odd number, mobile subscriber is in polygonal region；Work as intersection point
When counter is even number, mobile subscriber is outside polygonal region.
