Matrox has released a video on the photometric stereo technique featuring Smart Vision Lights products. Photometric stereo uses 3D surface orientation and its effect on reflected light to produce a contrast image accentuating local 3D surface variations.
In this video, a series of LM45 mini linear lights illuminates the object under inspection from four different directions, optimizing image capture. The algorithms analyze the reflection on the images and produce images with enhanced contrast. The resultant images emphasize surface irregularities such as scratches on a stainless-steel cylinder or a pinhole in a pill pack obscured by print and lighting.

Smart Vision Lights is close to breaking ground on a new $3 million facility in Norton Shores, Michigan. Located on a 6.7-acre site, the 36,000-square-foot building will have space for design and engineering — including areas for prototyping and robotics demonstrations — as well as assembly space and offices. The expansion, which nearly triples the size of SVL’s existing facility in Muskegon, could potentially create 15 jobs over the next two years.
SVL is experiencing a 30 percent year-over-year growth rate. The company’s expansion mirrors the explosive growth in the machine vision industry, with sales of systems and components reaching $709 million in the first quarter of 2018.
As SVL looks to expand globally, the company will keep its roots in western Michigan. “Our workforce is here, and with the strong automotive and automation industries in Michigan, the location aligns perfectly with the work we do,” says SVL president Dave Spaulding.
Join Smart Vision Lights on September 24 at 11 AM EST for the webinar The Growing Need for Precision in LED Lighting. Presented by Paul Powers, Director of Sales – Americas, the webinar looks at three main trends in machine vision lighting: the need for lights with nanosecond response times; the need to manage multiple lights; and the need for multidisciplinary light design that includes electronic, optical, and mechanical engineering skill sets.
When it comes to machine vision lighting, seeing is believing. SVL distribution partner JM Vistec exhibited three distinct demos of our lights at the 2018 Taipei International Industrial Automation Show, drawing big interest from attendees. Here’s what was on display:
Demo 1: SVL + SVS-Vistek
Purpose: To show SVL lights driven directly by the camera and without any other controller. Working demo uses three different colors of SVL Mini Ring Lights — RM75-470, RM140-625, and RM140-WHI — to quickly inspect sample defect on different spectrum color.
Demo 2: SVL + Hyper Focus
Purpose: To show SVL S75 Brick Light application on the Hyper Focus system.
Demo 3: SVL + ISVI
Purpose: To show SVL dual lighting solution on big-frame CCD (50M pixels) with high magnification telecentric lens application. The LXE300-WHI Linear light is set on OverDrive™ mode and TSLOT Extrusion light is used for constant lighting to inspect the sample.
