The
original scan was 20,654 data points , effective
probe radius = 0.937 mm ( 0.037 " ).
Typical 0.25 mm ( 0.010" ) point to
point, 1.00 mm ( 0.039" ) line
to line interval.
The
original raw data had 274 to 300 data points per scan
line.
Step
one is to grid the input so that all lines have the
same number of points, 301 per line.
Next
step is to calculate the local slope at each point and
find the actual contact point on
the
surface. This surface data set was then sparsed to 19
rows of 31 points per row.
File
contains a few rows of data points showing some of the
key advantages of touch
trigger
probe
digitizing . . . the raw data set is very accurate,
ordered with low noise.
