Perceptive Sight® Intelligent Grading
Artificial intelligence, the quantum leap in technology that is producing self-driving cars, is integral to Lucidyne’s GradeScan® system. The value of artificial intelligence springs from the sophistication of the technology it uses. GradeScan’s artificial intelligence uses accurate multi-sensory imagery at its foundation. Perceptive Sight® Intelligent Grading is a revolutionary method for grading lumber.
Working from GradeScan’s multi-dimensional board images, our Certified Graders’ team analyzes, differentiates and classifies defects in thousands of our customers’ boards, creating a knowledge base within the Perceptive Sight™ software which trains itself by reading through the samples, correlating images and labels.
For any new defects, ambiguous samples or rule changes, Perceptive Sight® is shown sufficient graded examples to train impeccably for accuracy and application.
Far from being stymied by new species, defects or products Perceptive Sight® can be quickly trained for accurate response. Self-adjusting Perceptive Sight® does a better job than a computer scientist analyzing, designing and writing code for new defects.
Lucidyne’s Perceptive Sight® Intelligent Grading is a game-changing system. All Lucidyne GradeScan® systems are now shipping with Perceptive Sight®, and many of our customers are upgrading existing systems.
An in-depth look at Perceptive Sight® from Lucidyne’s CTO Patrick Freeman.
Watch Now
“We bought the Lucidyne GradeScan® because we felt it was the most accurate scanner on the market after testing multiple systems from various manufacturers. The staff’s technical abilities, coupled with an unmatched enthusiasm, was a major reason for choosing Lucidyne. After five months of running, I know now more than ever that we made the right choice.” –Glenn Player, QC Manager, Charles Ingram Lumber

Board graded using Perceptive Sight® Intelligent Grading – showing actual results on board above.
Defect detection
Perceptive Sight® software completely “re-thinks” the way automated defect detection and grading is done. Using artificial intelligence, Perceptive Sight™ software is a quantum leap in technology that brings defect detection to a whole new level of accuracy, and allows extremely rapid responses to changes in your wood basket.
For example, Perceptive Sight® doesn’t just place a rectangle around a knot – it reports the actual shape and orientation of the knot head. Perceptive Sight® knows the minor – but critical – differences that confuse other methods of defecting.
Accuracy
With spot-on defect detection delivered by Perceptive Sight® software, grading accuracy becomes near-perfect.
GradeScan® with Perceptive Sight® software minimizes above-grade in all grades. It is not easily fooled by blond rings, compression wood or shallow wane. It separates pitch from pitch-colored knots. It can tell the difference between a bark pocket and bark encasement. It is not misled by pitch-filled shakes in Green Doug Fir. Grease spots and blemishes are not called knots. And Perceptive Sight® does so much more.

Uptime, uplift, & cost of ownership
GradeScan® has the best track record of uptime in the industry. Mills with GradeScan® in one mill have replaced competitor scanners in their other mills based on the increased uptime alone.
Superior uplift from our Perceptive Sight® defect detection and our optimization algorithms bring even more value.
Plus, GradeScan® has the lowest cost of ownership on the market – fewer parts to replace and less maintenance.
These three important factors, uplift, uptime and lower maintenance, make GradeScan® the most cost-effective scanner you can buy.
Low Maintenance
GradeScan’s enclosure is pressurized and temperature controlled, and therefore not affected by ambient environmental changes. It is mounted on an overhead carriage for easy maintenance – just give the glass a quick wipe between shifts and GradeScan® is running again.
Scalable to Your Mill Operation
Another great advantage of our Perceptive Sight® software platform is that GradeScan® is now scalable to meet the needs of any mill. No matter how fast or slow you run, how many products, grades or species, we can scale GradeScan® to meet your needs within your budget. GradeScan® is your solution to maximize your fiber and value recovery, regardless of your mill specifications.
GradeScan® Value-Added Tools


GradeVU® Projector System
Quality control is critical. GradeVU® can be configured to give you exactly the information you need to keep your productivity at peak levels. Choose to project every board solution on every board, or just on some boards.

TrueQ® Board Tracking System
As boards travel downstream from the scanner, they can get turned over, or crossed up and out of queue. It is critical to ensure that the correct solution is matched to the correct board, and Lucidyne’s patented TrueQ® does just that.

Grade Mark Reader
Our GMR can be installed stand-alone in a mill without automated lumber grading, or can be partnered with a GradeScan® system to increase the control you have on your line.
See MoreConfigurable to Your Mill
GradeScan® adapts to your physical mill layout seamlessly. Even in mills that believe there is no lineal option, experience shows that lineal is the best solution.
Our mechanical and electrical engineers have worked around catwalks, ducting, pipelines and other “obstacles.” Even if there’s no room to go left or right, GradeScan® can go up.
GradeScan® fits behind your planer in mere inches, and can actually butt right up against the planer itself; so the leading edge of the board is being scanned while the trailing edge is still being controlled by the planer.
The Lucidyne has always made GradeScan® fit into even the most challenging layouts. We just make it happen.
