Sony releases details of industry’s first SDK for polarised-sensor machine vision modules

Pregius IMX250MZR

Details of the industry’s first software development kit for camera modules based on Pregius IMX250MZR polarised image sensor have been released by Sony Europe’s Image Sensing Solutions.

Created to run on its new XCG-CP510 polarised module, the XPL-SDKW was previewed at Vision 2018 and is available immediately. Sony said it enabled development teams to cut polarised machine vision application design time and cost significantly.

The IMX250MZR sensor, the industry’s first to integrate polarisation functionality at the pixel level, can filter light in four planes – 0o, 90o, 45o, and 135o – with pixels assigned a plane in a 2×2 calculation unit.

Sony’s Stephane Clauss said: “We’ve worked in close consultation with our customers to identify the key functions for the SDK, and develop its  highly- optimised algorithms. And we will continue to add more over the next year.

“Depending on the dev team and application, a standard polarised-camera application would typically take between 6 to 24 months. Through the SDK, and its image processing library, the dev time for the same application can be cut to around 6-12 weeks.”

The use of polarised camera modules will prove vital in a wide range of applications and Sony has developed and validated software models for the major subset of these, including: weakness detection (for example, glass, PET and display manufacturing); inspection (for example, for manufacturing / ITS / pharmaceuticals); and, scratch identification.
