Theia lenses bring ANPR/LPR into focus

Theia Technologies says its range of 4K and megapixel NIR corrected lenses for ITS can be used in applications ranging from long-distance traffic surveillance and ANPR/LPR, to ultra-wide views without distortion. At the Vision 2018 show in Stuttgart, the company showed off for the first time its ML610M 6-10mm varifocal lens with 4k resolution, NIR correction for a 2/3” sensor covering the focal range of three prime lenses with up to 87 degrees horizontal field of view. The telephoto lens portfolio is

8886 Theia Technologies says its range of 4K and megapixel NIR corrected lenses for ITS can be used in applications ranging from long-distance traffic surveillance and ANPR/LPR, to ultra-wide views without distortion.


At the Vision 2018 show in Stuttgart, the company showed off for the first time its ML610M 6-10mm varifocal lens with 4k resolution, NIR correction for a 2/3” sensor covering the focal range of three prime lenses with up to 87 degrees horizontal field of view.

The telephoto lens portfolio is most popular for long-distance, high-detail applications such as ANPR/LPR and tolling, the company says, with 4k and 5+ megapixel resolutions maintained even in near IR light.

Mark Peterson, VP advanced technology at Theia, says: “Theia lenses are particularly good in NIR illumination with only a 5 micron focus shift, making reading number plates in low light and bad weather conditions an easier task.”

The company has models with Precise iris, or P-iris for improved depth of field and says that the lenses are “very compact for their telephoto focal range, size format and full feature capability, including models with motorised zoom, focus and IR cut filter”.

    Advances in vision technology are enhancing traffic surveillance and enforcement applications. Variable lighting conditions have long been a stumbling block for vision technology applications in the transport sector. With applications such as ANPR, the read-rate may vary between daylight and night and can be adversely affected by glare and low sun. Madrid, Spain-based Lector Vision had these considerations in mind when designing its Traffic Eye ANPR system, which combines off-the-shelf and custom hardware

    Gardasoft is demonstrating how to capture high-quality images of fast-moving vehicles using an innovative liquid lens concept. This, the company says, provides significant performance benefits over traditional, fixed-focus lenses. Many ITS applications require vision systems which can cope with widely varying distances between object and camera. A challenge in the ITS space is the high speeds which can be encountered, particularly in free-flowing traffic. Gardasoft’s approach features a shape-changing
