Log Merchandising

The goal of log merchandising is to capture the highest value logs from the forest before they are shipped to downstream processing facilities for primary breakdown.

360º Log Scanning

A ring configuration of Gocator® sensors scans the entire circumference of the log and generates a complete 3D point cloud, revealing shape features such as taper, sweep, and crook.

Gocator® 2880

3D Volume Measurement

Scan data is used to calculate wood volume while excluding the presence of bark, determine how timber should be cross-cut into various lengths for sorting into sawlogs, veneer bolts, and pulpwood.

Gocator® scans and helps identify defects such as bark, splits, outer knots, and debarker tear-out.

Robust Defect Detection

Gocator® generates a height map and intensity image for total surface measurement in 3D and 2D.

Complete Log Imaging
Log Optimization

There are two major machine centers for log processing based on headrig or end-dogging machinery with chipper heads and multiple bandsaws.

High Ambient Light Immunity

chroma+scan scanners are able to generate high-precision 3D data, despite the intense ambient overhead and spot lighting used in sawmills.

Fast, high-sensitivity scanners with superior dynamic range

chroma+scan 2440

Determine Optimal Log Breakdown

Banks of chroma+scan 2440 scanners project multiple laser lines along the log length to generate 3D shape data at up to 120 Hz. The resulting 3D model is analyzed to measure shape features and compute an optimal saw solution.

Excellent Dark Log Performance

High-sensitivity with multi-exposure control delivers high-resolution scanning of low-contrast targets such as dark logs.
Cant Optimization

A combination of cant edger and gangsaw systems cut cants into boards in order to achieve high-volume, high-value production.

High Scan Speed with Full Multiplexing

chroma+scan 2430s scan at 90 Hz and are fully multiplexed to prevent scanner crosstalk, with the ability to handle up to 3 banks of scanners simultaneously.

Small Clearance Distance

Short standoffs allow scanner placement within existing mill machinery.

Efficient Sensor Bank Design

Multi-line laser package minimizes number of scanners to cover full board length. Tightly spaced laser lines allow for full 3D scans in just 6” of travel.

Machine Monitoring

Gocator® is an all-in-one solution that combines scan, measurement, and control decision-making logic in a single device for error-proofing in various machine centers.
Board Optimization

Boards that are output from the cant edger or gangsaw are then scanned transversely in edging and trimming applications.

Edging Applications

Banks of Gocator® 200 scanners generate 3D profiles of each board, which are then positioned to the saw in an infeed. Based on the profile data, saws are set to extract optimal board widths.

3D smart sensors with modular design for transverse board optimization

Gocator® 200 scanners provide 3D data for optimal length cutting decisions. The scanners can also instruct machinery to drop out an undersized board for ripping down by a reman machine and for later re-entry into the trimmer.

Trimming Applications

Gocator® 200 scanners provide true differential lumber thickness profiling without being affected by chain vibration or board bounce.

True Coplanar Scanning
Finished Lumber Grading

Gocator® is used to inspect each board as it passes by on a lugged chain deck.

Maximum Value Recovery

By scanning for shape, surface color, and tracheid grain angle, Gocator® 200 multi-point profile scanners generate rich data for final defect analysis and sorting by grade.

3D smart sensors with modular design for mixing 3D profiling, tracheid, and color

The Gocator® 200 bolt-on lightbar allows the scanner to build high-resolution color images for identifying surface defects such as splits, rot, and more.

Color Vision for Surface Defect Detection

Robust Tracheid Detection

Combining high-density 3D profiles with tracheid scanning at high scan rates allows Gocator® 250 scanners to maximize value recovery by detecting features such as grain angle, sound or unsound fiber, and blond knots.
