Software offers 3D image acquisition in AOI

Software developed by Viscom enables precise 3D image acquisition in the automatic optical inspection (AOI) area.

The representation of side views of electronic components, a pronounced weak point on many 3D systems with orthogonal cameras, can now be displayed in realistic detail with the angled cameras modules on the 360View.

It provides height information, and displays component sides for 3D AOI. The operator is offered a textured image with no lateral inaccuracies, says the company, from all of the freely selectable viewing angles. This advance will be available for the company’s S3088 ultra gold, S3088 ultra, S3088 ultra blue, S6056 and S7056 (AOXI model), with a new vVision software version.

Many conventional AOI systems work with just one orthogonal camera. To build a 3D reconstruction, projectors cast a fringe pattern on the inspected object one after the other from an angled position; these patterns are then available via the camera as information for calculating the spatial images. In comparison, the Viscom camera modules integrate an optional four- or eight-angled view cameras in addition to the orthogonal cameras; only one projector is needed. As well as speeding up image acquisition speed, this also provides accuracy for the display of individual components. For example, it is possible to look beneath the bent leads of a QFP, using the software.
