What is the role of calibration targets in VIM?

They increase data volume They are decorative They replace GPS They calibrate sensors and verify scale

Correct Answer:

They calibrate sensors and verify scale

Explanation:

Calibration targets act as precise reference objects in a scene. By including these targets when you collect data, you can determine the sensor’s characteristics (like lens distortion and focal properties) and adjust the measurement model accordingly. This process ensures that the measurements you extract from the data correspond to real-world dimensions, so the overall scale is accurate. In VIM, targets are used to calibrate sensors and verify that the reconstructed measurements match true sizes, which is essential for reliable inspections. They aren’t meant to increase data volume, act as decoration, or replace GPS.
