The machine vision fraternity knows that it is a complex and computer intensive job to use a 3D point cloud to solve industrial inspection tasks. Yet what the team at Euresys understand, is that most 3D inspection problems can be solved using a 2.5D representation. What’s more, 3D sensors usually only generate a 2D array of heights and distances. This is where the Easy3D
library product from Euresys steps in. Easy3D
is a set of software tools which enables the development of 3D machine vision inspection applications. In this role, it provides functions to generate ZMaps which are an effective and very flexible way to deal with 2.5D data. A ZMap is the projection of a point cloud on a reference plane, where distances are stored as pixel grey scale values. Importantly, ZMaps are distortion free, with a metric coordinate system. Easy3D
exposes functions to convert arbitrary 3D data like point clouds to 2D representations, which form the ZMaps.
The applications for such technology are wide and include the electronic manufacturing and general manufacturing industries.
The result is a more cost-effective solution which can, depending on application, be up to 20 times faster than conventional 3D systems. And it is a system which is finding many fans in the machine vision industry.
