workpiece to be scanned, and then the industrially calibrated industrial camera
captures the reflected light, and is calculated. Shape data of the workpiece.
KSCAN includes infrared band and blue band. One of the infrared band is
adopted by the photogrammetry mode, the other and the blue light band are used
by
infrared and the blue laser modes respectively. There is a certain angle
between the two cameras of the scanner. The fields of view of the two cameras
intersect to form a common field of view, and also it’s called the reference
distance, while the common focal range is called the depth of field. In general,
the reference distance and depth of field of the scanner are related to the
instrument, and the specific values are subject to the actual test data of the
equipment. And the laser band and the resolution also related to them. The
common reference values are as shown in Table 1-1.
