SKIP

Skip or unskip image measurements

This program skips and unskips photo measurements according to the input statements in skip.dat. SKIP also supports renumbering photo measurements.

Set the following three parameters in the GUI:

1. [skip_limit]: Lower Wii limit for skipping points. Points with a lower Wii are not skipped.
2. [unskip_limit]: Upper Vi limit, in µm, for unskipping points. Points with a higher Vi are not unskipped.
3. [-c]: If this switch is set, all SKIP statements in the SKIP file for control-point photo measurements are ignored.

The following files must be available for input in the current working directory:

1. skip.dat, containing case-sensitive SKIP and UNSK statements written by RELAX or BINGO. A RENU statement is also supported for changing the point numbers of photo measurements.
2. image.dat, containing photo coordinates for processing with BINGO.

SKIP and UNSK statement format

*--- <_Point_> <_Photo_> <_Line_> <_Rays_> <_Wi_/_Vi_>
SKIP

RENU statement format

*---  <_Old_Name_>  <_Photo_>  <_Line_>  <_New_Name_>
RENU

Hints

1. RELAX, BINGO, or LIMBO renames any existing SKIP file to old-skip.dat during startup.

2. An S is inserted in column 1 of the line for each skipped point.

3. BINGO takes the following actions for skipped points:

   • The program calculates the residuals as normal. If the residuals are under a certain limit, the point will be output in an UNSK statement in file skip.dat.
   • The program determines whether the point has an incorrect point number or only a faulty measurement. BINGO checks the object points of previously skipped data and points marked for skipping in the current run. It transforms these points into the relevant images and compares them with their photo measurements. If they agree within a specified limit, the program displays a message to change the point name. This operation can be time-consuming for large blocks with many skipped measurements, so it can be disabled in BINGO to save computation time.
   • You can also reduce BINGO runtime by changing the S in column 1 of previously skipped lines in image.dat to *. An asterisk in column 1 makes a line inactive. In all BINGO files, one or more lines can be made inactive in this way.

4. Select Run > Cycle to run BINGO and SKIP repeatedly for automatic error elimination and reactivation until block processing is complete.
