SAL3D library for quality control applications

An Aqsense product story
Edited by the Engineeringtalk editorial team Jun 30, 2009

Aqsense has launched SAL3D (3D Shape Analysis Library, in C++ API), offering the latest functionalities to OEMs and systems integrators.

The library is designed for those developing quality control and 100 per cent production in-line inspection applications.

The library is built upon a modular configuration based on four tools.

The peak detector tool enhances the extraction of profile co-ordinates from laser stripe images.

Capable of distinguishing Z-steps of 5microns, with a camera-laser set up of 90 degrees and field of view of 130mm.

The metric calibration tool provides an easy calibration procedure using a specially designed object, obtaining true XYZ metric co-ordinates, allowing metric measurements and avoiding perspective distortion.

The merger tool minimises occlusions by using multi-camera configurations, merging their images into a single, smooth one.

The match3D tool provides 3D inspection and measurement of free-form objects.

Defects can be detected by comparing scanned parts with their model.

The ultra-fast registration method allows 'mathematical' alignment, avoiding expensive mechanical fixtures and allowing 100 per cent control at production-line speed.
