Figure 16. Found contours screenshot
If you see the text “The number of contours is fewer than 4” in the terminal window, it means that the
contours were not found (see Figure 17).
Figure 17. Bad search contours terminal screenshot
In this case, check the contours on the screen and identify the problem. For example, it can be one of
these problems:
• The small contours were not found. Solution: change <contour_min_size> value in the
settings.xml file.
• The contours were not found because of the lighting conditions. Solution: change the lighting
conditions.
• The application did not find the contours that are located too high on the frame. Solution: change
the <roi> value in the settings.xml file.
• Some additional contours were found. Solution: change the place for the calibration or move
these additional objects away from the camera view. You can also decrease the <roi> value in
the settings.xml file if these additional contours are located at the top part of the calibrating
frame.
