Further, according to round or rectangular window method principle factorization, round or rectangular window method scene is read
The data of measurement, the Joint Trace line chart then generated；The white dynamic adjustment of the case where program is according to measurement data is round or rectangle samples
The position of window, quantity and radius size, while judging and recording the quantity of various endpoint type traces, calculate joint
Average trace length and trace midpoint d ensity.
Further, the circle is appeared using cross two surveys line that intersect vertically, and joint orientation relies on two endpoint
Position determine.
Further, the rectangle is appeared using two surveys line that intersect vertically of L-type, and joint orientation relies on the position of two endpoint
Set determination.
Further, appearing for other shapes is minimised as principle according to form with measurement error, using round and square
Shape sampling window legally constituted authority meter Joint Trace length and surface density.
In conclusion advantages of the present invention and good effect are as follows:
Circle is appeared using cross two surveys line that intersect vertically, and joint orientation is come true by the position of two endpoint
Fixed, the later period facilitates Analysis of Size Effect and carries out Joint Trace length and surface density statistics using rounded sample window technique；Rectangle is appeared
Using two surveys line that intersect vertically of L-type, joint orientation is determined by the position of two endpoint, and the later period facilitates dimensional effect point
Analysing and utilize rounded sample window technique to carry out, Joint Trace is long and surface density counts；For appearing for other shapes, according to its form
It is minimised as principle with measurement error, using round and rectangle sampling window legally constituted authority meter Joint Trace length and surface density.
The present invention reduces truncate or cut long mistake caused by sampling as far as possible according to form selection sampling window shape of appearing
Difference, statistics joint as far as possible is in the intact form on surface of appearing.
