Eliminating Distortion in Machine Vision Applications

Eliminating Distortion in Machine Vision Applications

Presented by: Mark Peterson, Theia Technologies

Today’s vision systems have many advantages if you have the right lens for the job. Applications such as Autonomous Mobile Robots (AMRs), bin picking, stereo vision, and agricultural monitoring all require wide angle lenses. Until recently, only fisheye lenses were available for imaging ultra wide fields of view. But fisheye lenses have high levels of barrel distortion, affecting resolution at image edges, ultimately limiting the application uses for these lenses.

Only rectilinear lenses provide ultra wide fields of view and correct the barrel distortion inherent in traditional wide angle lenses without losing resolution and in real-time without software correction and its latency. Peterson discusses an innovative optics solution which addresses these issues, advancing the practical use of wide angle optics in machine vision applications.

About the presenter
Mark PetersonMark Peterson is a co-founder and vice president of advanced technology of Theia Technologies. He enjoys investigating new technologies that can improve and advance Theia's line of products and solutions, allowing Theia to be a leader in optics and imaging. Peterson believes that understanding a broad range of technologies and bringing together ideas from different areas is fundamental to building exciting new products that allow customers to accomplish their goals.

Prior to founding Theia Technologies, Peterson worked in advanced development at InFocus Systems. There, he and Jeff Gohman, the president of Theia Technologies, developed the core technologies for creating ultra-wide angle low distortion lenses that allowed Theia to spin off.

Peterson has over 40 patents and has contributed to conferences on machine vision and white papers on optics and lenses. He has a bachelor’s and master’s degree from the University of Wisconsin and has been working in the optics industry for 25 years. In his time outside the office Peterson is leader of a pack of three malamutes and puts in lots of miles on his road bike. Peterson and his wife, Lynn, are trying to minimize their environmental footprint and recently built a small home on their property in Lake Oswego, Oregon.
