11.5 3D Features
Calculation example (DataFormat3D=3):
Suppose that the 3D data of image column n has the
following data: 14 / 140 / 10 / 128 (see also Fig. 11.12).
The position of the laser line is in this case 232.75: integer part is calculated from the 8 bits of
3D row 0 followed by the 4 MSB of 3D row 1: 0b000011101000 = 0x0e8 = dec 58. The fractional
part is calculated from the 4 LSB of 3D row 1: 0b1100 = 0xc. This value must be divided by 16:
0xc / 16 = 0.75.
The laser line width is 10 pixels (6 LSB of 3D row 2).
The LL_HEIGHT value is in this case 8 (=4 MSB of 3D row 3). These are the 4 MSB of the mean
value between the two pixels around the peak position. At 12 bit resolution, the mean value
lies between 0x800 (=2048) and 0x8ff (=2303).

Transmitted data in 2D&3D mode
The transmitted image in 2D&3D mode is shown in Fig. 11.13. The data is transmitted in the
following order:
•
Raw image
•
3D data
Resulting height in 2D&3D mode is:
Hres = Pea 4 (if DataFormat3D=3 or 4), or
Hres = Pea 2 (if DataFormat3D=2)
