Camera Calibration
Perform the following steps to three-dimensionally measure and quantize the image
from the camera, and then calculate the size of every target. The VCA detection will
be more accurate if the camera calibration is configured.
Steps:
1. Check the checkbox of Camera Calibration to enable this function.
2. Select the calibration mode as Input Basic Data or Draw on Live View Video.
Input Basic Data: Input the mounting height, viewing angle, and horizon
ratio of the camera manually.
Draw on Live View Video: Click Draw Verification Line (Horizontal) /
(Vertical) to draw a horizontal/vertical line in the live view, and input the
actual length in Real Length field. With the drawn reference lines and their
real length, the camera can conclude other objects appear in the live view.
3. (Optional) Check the checkbox of Enable Verification of Camera
Calibration, click the Horizontal Verify / Vertical Verify button to draw a
horizontal / vertical line on the live video, and then click the Calibrate button
to calculate the line length. Compare the calculated line length to the actual
length to verify the calibration information you set.
4. You can click Delete to delete the drawn lines.
5. Click Save to save the settings.
Note: If the live view is stopped, the camera calibration is invalid.
