3 Product Overview
3.1 Introduction
The scan 24x0 is the new-generation, high-speed, high-density 3D profile
scanning system for primary log optimization. The sensors are based on LMI's field-
proven FireSync platform, which provides a synchronized, scalable, distributed vision
processing architecture for building reliable, high performance systems. High reliability
and simple, rapid installation are achieved with a single cable for power, data, and
synchronization. Communication is via Gigabit Ethernet.
3.2 Measurement Principles
The scan 24x0 sensors function on the principle of structured light triangulation.
A semiconductor laser with special optics projects fans of light onto the target. Digital
cameras mounted at an angle to the laser plane acquire images of the light pattern
created on the target. These images contain the basic information needed to compute
distances to the target.
