While you are drawing, hold down the SHIFT key to create non-sensitive areas.
Drawing by itself without the SHIFT key marks out sensitive areas.
4.8 Object Properties
Selecting this tab allows you to monitor the properties of a marked object over a longer
period of time and observe changes.
The properties of a moving object are always changing. An automobile does not always drive
at a constant speed; a person sits down and stands up or changes direction.
The color of an object depends on the lighting of the image, for example. Different colors are
detected under a floodlight than in the shade.
Using the values displayed here, you can estimate which minimum and maximum values you
must enter for the creation of a task to ensure the desired objects are captured.
Furthermore, the values displayed help to check and refine an existing calibration. Implausible
values indicate faulty calibration.
– Highlight an object in the camera image by clicking it.
The object is marked with a yellow flag.
– The properties of the object are displayed on the right-hand side of the window.
The numerical value for the property is updated every second while the object is marked.
The progression graph displays the change in values of each property during the previous
30 seconds.
The Color property is not displayed using the numerical value and progression graph.
In the lowest field, the color properties of the marked object are displayed using color
columns that are arranged according to their weighting. The further to the left a column is, the
higher its proportion of the object's color property.
If you move the mouse cursor over one of the color columns, a tooltip displays the values for
hue, saturation and value (HSV), as well as the weighting of the color.
