The specific algorithm comprises the following steps:
step 1: if the position point of the current person/vehicle is the first point reported in the travelling track, not judging, setting that the deviation from the planned route does not occur currently, otherwise, judging as follows;
step 2: finding a section of the planned route closest to the current person/vehicle location;
and traversing line segments formed by connecting adjacent planning points in the planning route in sequence, and solving the vertical foot between the current position point of the personnel/the vehicle and the line segments, wherein if the vertical foot between the current position point and one of the line segments is positioned on the line segment, the distance between the current point and the line segment, namely the distance between the point and the vertical foot on the line segment, is solved. After traversing, finding out the line segment closest to the current position;
step 3: comparing the distance between the current position and the nearest line segment with a set distance threshold value, if the distance is larger than the set threshold value, judging that the current state is a state that the position deviates from the planned route and marking, otherwise, continuing the subsequent judgment;
step 4: forming a vector by the last position point of the person/vehicle and the current position point, and calculating the included angle between the vector and the line segment vector nearest to the current position; if the included angle is larger than 90 degrees, judging that the current state is deviated from the planned route state, and marking.
Step 5: if the off-route state occurs for 5 times continuously, judging that the person or the vehicle has the situation of off-route, and generating off-route warning.
The off-route detection algorithm is described in detail below in conjunction with the legend:
as shown in fig. 4, A, B, C, D, E is a route point marked when a route is planned, and the points are sequentially connected to form a planned route a-B-C-D-E;
in fig. 4, track point 1 and track point 2 are 2 points in the actual action track of the patrol personnel/vehicle, wherein track point 1 is the first track point, track point 2 is the 2 nd track point, and when only the first track point appears, the current track point is not deviated by default and is not judged; when the track point 2 is transmitted, a AB, BC, CD, DE line segment in the planned route is traversed, the sags of the current track point 2 and the line segment are sequentially solved, and the distance from the track point 2 to the line segment is recorded under the condition that the sags are on the line segment, as can be seen from the figure, the sags from the track point 2 to the AB and the BC are respectively on the AB and the BC, and the sags from the track point 2 to the CD and the DE are not on the CD and the DE. Therefore, solving the distances from the track point 2 to the AB and the BC, namely d1 and d2 in the graph; then, the line segment with the shortest distance from the track point 2 is found, and d1< d2 is known from the figure, so the line segment with the shortest distance from the track point 2 is AB.
When d1 is greater than the distance threshold, judging that the current travelling track deviates from the planned route, otherwise, continuing to judge the included angle between the vector formed by the track point 1 and the track point 2 and the vector AB, as shown in FIG. 5.
And when the included angle between the vector formed by the track point 1 and the track point 2 and the vector AB is larger than 90 degrees, judging that the current state is deviated from the planned route.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and variations could be made by those skilled in the art without departing from the technical principles of the present invention, and such modifications and variations should also be regarded as being within the scope of the invention.
