VISMEASURE (Statement)

Function

Measures features in the window (area, center of gravity, main axis angle).

Format

VISMEASURE <Window number>, <Coordinate X>, <Coordinate Y>,

<Processing object>, <Mode>, <Binary lower limit>[, <Binary upper limit>]

Explanation

<Window number> Designates the window number (0 to 511).

<Coordinate X> Designates the X coordinate (0 to 511).

<Coordinate Y> Designates the Y coordinate (0 to 479).

<Processing object> Designates the object to measure (0 or 1).

0: Black (brightness value < binary lower limit, binary

upper limit < brightness value)

1: White (binary lower limit ≤ brightness value ≤ binary

upper limit)

<Mode> Designates the feature to measure.

0: Accumulated brightness, area

1: Accumulated brightness, area, center of gravity (primary

moment)

2: Accumulated brightness, area, center of gravity (primary

moment), main axis angle (secondary moment)

Note (1): The more the features are, the longer the time process

takes.

Note (2): When this command is executed, the process screen 3

(VISWORKPLN 3) is used as a work area and data on the

process screen 3 are not guaranteed. Also, you cannot use

the process screen 3 for processing.

Note (3): For this instruction, a µ

µµ

µVision board (option) is required.

<Binary lower limit> Designates the lower level for binarization (0 to 254

lower limit < upper limit).

<Binary upper limit> Designates the upper level for binarization (1 to 255

lower limit < upper limit).

If this is ignored, 255 will be the default setting.
