Note
●
For Height Calibraon, the calibraon target should be a complete perpendicular to the
ground, the posion of four calibraon lines should be scaered, and the endpoints of any
two calibraon lines cannot be on the same horizontal line.
●
For Length Calibraon, the calibraon target should be a target parallel to the horizontal
plane, and the four calibraon lines should be scaered and are recommended not to be
intersect.
5. Enter the actual length or length of each calibraon line.
6. Click Calibraon.
The upper-right corner tag would show the calibraon result.
7. Verify the calibraon result.
1) Move and adjust the vericaon line to the target on the image.
2) Click Measure.
The vericaon value would be calculated at the right side of Measure.
3) Compare the calculated size to the actual size to verify the calibraon result.
Note
●
You cannot start vericaon without nishing calibraon
●
If the measured result deviates greatly from the actual size, it is recommended to recalibrate.
What to do next
If you select Target Length/Area on Stream under Display Conguraon during task conguraon,
the target length or area value would be overlaid on stream.
