Vision Sensor Manual
L(uminanz) 4 Value for color parameter, signed integer, [1/1000] *1)
A 4 Value for color parameter, signed integer, [1/1000] *1)
B 4 Value for color parameter, signed integer, [1/1000] *1)
Result index 4 Index in list, signed integer
Color distance 4
Distance between taught and current color, signed integer,
[1/1000] *1)
Area 4 Area of the BLOB, without holes, in pixels
Area (incl. holes) 4 Area of the BLOB, including holes, in pixels
Contour length 4 Number of pixels of outer contour
Compactness 4
Compactness of BLOB (Circle = 1, all other >1)
The stronger the shape of the BLOB deviates from circle the
larger the value of compactness will be.
Center of gravity X 4 X- coordinate of center of gravity of BLOB
Center of gravity Y 4 Y- coordinate of center of gravity of BLOB
Center X 4 X- coordinate of fitted, geometric element (rectangle, ellipse)
Center Y 4 Y- coordinate of fitted, geometric element (rectangle, ellipse)
Width 4
Width of geometric element.
Width >= 0, width >= height, negative value indicates failure
Height 4
Height of geometric element.
Heigth >= 0, height <= width, negative value indicates failure
Angle (360) 4
Orientation of width of object in degree (range: -180 ... +180°,
0° = east, counterclockwise)
Eccentricity 4 Eccentricity numerical (range 0,0 ... 1,0)
Face up/down, area 4 Face up/down discrimination, based on area, indicated by sign
String 1...n
Maximum
length 127!!
Contents of Code, depending from code string length may
change, if a fix string length is needed, parameters minimum
string length (detector specific data output) and maximum
string length (detector parameters) have to be used.
String length 4 Length of Code in Bytes
Truncated 1
0x00 = Code
complete,
0x01 = Code
truncated
Code truncated
Checksum 1 XOR-checksum of all bytes in telegram
Trailer
1 - max.
8
End of string (Trailer)
*1)
All detector-specific data with decimal places are transmitted as whole numbers (multiplied by 1000) and must
therefore be divided by 1000 after receipt of data.Values are transferred in format "Big-endian". (there are two
different architectures for handling memory storage. They are called Big Endian and Little Endian and refer to the
order in which the bytes are stored in memory, in the case of the Vision Sensor architecture the data is stored Big
End In first)
