Calibration
In order to generate a range image which closely represents the physical contours of an object, the sensor must
transform raw peak data into real-world coordinates as well as remove the distortion from the camera lens. In addition,
the sensor my compensate for perspective distortion, which is illustrated in the following figure:
Feature
Description
1
Although the two red stripes have the same width, the lower strip
appears more narrow.
2
The orange stripe shows the width of the lower red stripe as seen by
the camera relative to the upper stripe.
The green portions highlight the difference in appearance between
the two widths.
Factory calibration removes any distortion in the calibrated image.
