Method.First, the coordinate value of the beginning and end of sliding trace is obtained to obtain the coordinate value at midpoint, then progressively per adjacent 2 points
Midpoint is taken, which is divided into multiple apart from identical line segment.Because 3 points can determine a circle, therefore will obtain
Point coordinates value since the starting point of sliding trace, obtains per adjacent 3 points to determine a circle, and then obtains the circle pair successively
The radius answered, the inverse of radius are the curvature of orbit segment where corresponding 3 points of the circle.By repeatedly calculating, one can obtain
Group curvature value, the corresponding sliding trace is from origin-to-destination, per the curvature of the corresponding orbit segment of adjacent 3 points.It obtains wherein most
Big curvature value is as the maximum curvature of the sliding trace, then, the central point of the corresponding orbit segment of this maximum curvature
The as inflection point of the sliding trace.
In technical solution disclosed in the present embodiment, sliding trace is subjected to multiple averaging point, by calculate maximum curvature come
Determine the inflection point of sliding trace, this method principle is simple, not error-prone, and calculates precision, from multigroup curvature data of gained
Maximum curvature is determined, so as to precisely determine the inflection point of this sliding trace.
