How Gocator Works • 51

Resolution and Accuracy

The following sections describe X Resolution, Z Resolution, and Z Linearity. These terms are used in the
Gocator datasheets to describe the measurement capabilities of the sensors.

X Resolution

X resolution is the horizontal distance between each measurement point along the laser line. This
specification is based on the number of camera columns used to cover the field of view (FOV) at a
particular measurement range.

Because the FOV is trapezoidal (shown in red, below), the distance between points is closer at the near
range than at the far range. This is reflected in the Gocator data sheet as the two numbers quoted for X
resolution.

X Resolution is important for understanding how accurately width on a target can be measured.

When the Gocator runs in Profile mode and

Uniform Spacing

is enabled, the 3D data is

resampled to an X interval that is different from the raw camera resolution. For more
information, see

Spacing (Data Resampling)

on page 59.
