Automatic Wayside Wheel Surface Inspection System

TreadView is Beena Vision's sophisticated Automatic Non-contact Optical Wheel Surface Inspection System. TreadView is designed to inspect wheel tread surface, flange, and plate areas at normal track speeds.

This system offers visual inspection of complete wheel tread and flange surface using optical imaging and laser scanning. The objective of the system is to determine any surface abnormalities of the wheel that can be detected using high resolution images of the wheel and high density 3D data of the wheel surface.

TreadView deploys a unique state of art digital imaging and laser scanning technology for maximum data density, accuracy, and efficiency. The product benefits from sophisticated image processing algorithms to assess wheel tread and flange surface condition from acquired multispectral multi-illumination images.

A major highlight of the system is that it is designed to operate in mainline speeds of up to 60mph (100km/h) for greater utilization by rail operators. Another important advantage of the system is that it can operate at very low speeds, where impact and force measurement-based systems fall short of detecting wheel surface problems such as flats.

A simplified version of the system is available, and it is designed to measure wheel out-of-roundness for mainly high speed passenger train operators.
