1.2.4 Color processing
Figure 27 shows the program window for color recognition and classification which can be found
under the tab “PROCESS COLORS“.
Figure 27: Color recognition and classification program window
The window arrangement and operation is similar to the program window “TEACHING IN
COLORS“ except for the three buttons on the left hand side of the color table which are
substituted by three number boxes.
COLOR INDEX
The color number of the recognized or classified color is shown in the field ”COLOR INDEX“
and represents the result of the entire sensor system’s signal processing path. This number is the
equivalent of the row number in the color table. If in the recognition (checking) processing mode
the tolerance boundaries were exceeded, the color number becomes 255. In addition the result is
also available at the sensor system’s communication interface.
COLOR DIST
The Euclidean distance between the actual measured color and the recognized or classified
(matched) color value is displayed in the field ”COLOR DIST“. If the cylindrical tolerance mode
is selected the euclidean distance becomes a 2-dimensional distance vector (2-dimensional color
vector). All other processing modes show a 3-dimensional euclidean distance vector.
Hint:
If in the processing modes “CHECK CYL“ and “CHECK SHP“ the tolerance room was
exceeded or the color was not recognized (Index 255), the distance to the next closest color is
calculated and shown in the field ”COLOR DIST“.
