After obtaining a rough approximation for a color's range of HSV values, the accuracy can be adjusted
further by selecting the
Manual
option, which will replace the color spectrum with boxes containing the
current HSV values for the channel. These can be adjusted by using the numeric keypad the interface
brings up when a value is pressed on the KIPR Link's touch display.
Manual adjustment is particularly useful when the color channel needs to discriminate among objects
having related, but distinctive colors, such as the orange and red objects in the above image.
Pressing the
Done
button reverts the display to the channel listing for the configuration, from where
more channels can be added.
Setting Up a KIPR Link QR Scanning Channel
When a channel is added to a configuration, it's type is specified either for
HSV Blob Tracking
or
QR Code
Scanner
. There is no additional specification required for QR scanning. The channel type is identified by
a different icon for QR codes than for color tracking. A sample program is given below that illustrates
how a scanned QR code is decoded.
