Figure 12.3: Component engineering drawing with specified measurements.
Calibrate and correct the image
The overall gauging process requires a relatively high resolution image that has
been grid calibrated to minimize camera lens and perspective distortion; see
for details. The calibration image must be stored on a USB
flash drive to be accessible to the vision script running on NI myRIO. In addi-
tion, applying the correction to the image itself will improve the measurement
accuracy and automatic detection of straight edges.
illustrates this technique.
