Imatest attended the P2020 meeting on May 13 and 14, 2019 in Ann Arbor, Michigan. Paul Romancyzk, PhD., Senior Imaging Scientist, and Rob Sumner, Lead Engineer, represented Imatest. Paul co-led the discussion on Color Separation within the Image Quality for Machine Vision subgroup.

Not all MTF measurement systems will necessarily provide the same results. The quality of the test target can impact the measurements you obtain. Long distance tests are ideally performed at the hyperfocal distance, where there is enough depth of field to have acceptable focus at infinity. Long-range tests which exceed the available space within your lab or factory are the most challenging. A collimator or relay lens system can be used to produce virtual targets at a simulated distance. The measurements obtained through a collimator can diverge from measurements obtained from free-space test targets. This article will discuss how to cope with that.
Imatest will attend AutoSens in Detroit on May 14-16, 2019. AutoSens is a 3-day workshop, conference, and exhibition advancing the education for and development of vehicle perception technology. It brings together over a thousand minds in vehicle perception, ADAS, and autonomous vehicles twice a year—in Detroit, Michigan USA in May, and Brussels, Belgium in September. Each event includes conference sessions, discussions, collaborations, debates, networking, business meetings, interactive learning, autonomous driving demonstrations, and technology exhibition showcasing.
Imatest sent two engineers to the IEEE P2020 Automotive Imaging Quality face-to-face meeting in Dusseldorf, Germany this past February in 2019. The IEEE P2020 standard, which is still in development, aims to define KPIs and test procedures to address the many challenges relevant (and often unique) to automotive imaging.
The group hopes to publish the standard in the year 2020 (no relation to the standard’s identifying number) as a unifying guideline for developers of autonomous driving systems. Most driver-assist and autonomous-driving systems rely heavily on cameras despite the significant press other imaging modalities, such as LIDAR, have received. As Level 3, 4, and 5 autonomous vehicles start to come on the road in 2020 and beyond, it is vital that these systems have an agreed-upon set of rigorous performance metrics. (more…)
We are pleased to announce that beginning January 2019, we are offering Imatest branded light panels and boxes. Imatest has responded to feedback from our customers by creating these two new uniform light sources. Our new LED Lightbox and Light Panel offer a wide variety of light intensities and color temperatures including near-infrared channels. We designed them to integrate easily with test fixtures, allow for precise chart alignment with chart rails, and to serve a variety of testing scenarios.
“We wanted to offer our own Imatest branded hardware that has been vetted and tested by our engineers which enable reliable results when used with our software and test charts. Our goal is to provide solutions for image quality testing that produces the results our customers need to exceed their expectations. The Imatest Light Panels and Lightboxes are made with the same high standards for quality that are found in our charts and software,” says Christian Taylor, Imatest’s Hardware Engineering Manager.
Imatest partnered with Shenzhen Polytechnic University to support the digital image quality testing curriculum at the university. With the expansion of their image quality program, Imatest sponsored and authorized the development of a state of the art research and education lab.
The lab and ceremony
On October 31st, 2018, Henry Koren, Director of Engineering, and Ian Longton, Imaging Science Engineer joined Shenzhen Polytechnic Executive Vice Presidents of Communication Engineering, Dean He Yuhua and Yang Yunyan, Vice President Zhang Xuilang, and Colorspace General Manager Nick Liu and colleagues for the official unveiling ceremony.
Witnessing the Aurora Borealis should be at the top of every photographer’s bucket list. This guide details the most important considerations for capturing images of the Northern lights. To be successful, you’ll need to be in the right place at the right time, equipped with the right camera and a decent amount of luck on your side.
