Long Line Filter Type

T he Long Line filter finds the longest continuous line or stripe of data in the image and rejects the rest of the data. The long line filter is also forced to be used during calibration. The laser stripe may be broken up due to the geometry of the part being measured. This filter finds the longest unbroken line. This is often used with sphere measurements. A section of the strip is considered continuous based on the following parameters:

Above: This value determines the number of pixels in the image that the next pixel is allowed to rise and still be accepted as part of a continuous line. The value indicates the number of millipixels above the current pixel that the filter will still use.

Below: This value determines the number of pixels in the image that the next pixel is allowed to fall and still be accepted as part of a continuous line. The value indicates the number of millipixels below the current pixel that the filter will still use.

Right: This value determines the number of permissible missing millipixels to the right of the current pixel and is still considered a continuous line.

Point Reduction Filter: This check box determines whether or not PC-DMIS filters points along the scan line. If marked, you can select the desired percentage of total points to filter. If cleared, the complete data set is acquired without any filtering.
