Machine vision image processing enhanced with new 3D tools
Published: 15 May 2012 - Neil Mead
MVTec is now including enhancements to 3D tools that are sure to open doors to new vision applications. Many new and enhanced features will be launched to the UK as MVTec take HALCON 11 on its worldwide launch tour. Genuine object identification now becomes a reality with sample-based identification, capable of differentiating a large number of objects. This technology can recognise trained objects based on characteristic features like colour or texture only, thereby eliminating the need to use special imprints like barcodes or data codes for object identification purposes. This is claimed to even work with warped objects or varying perspective views of the object. An additional option is to learn an object from any side view by using samples showing all relevant angles.
Furthermore, the new 3D surface comparison tool identifies an expected and measured shape of a 3D object surface, said to be a unique technology of HALCON 11. The surface can be reconstructed by any 3D technology available in HALCON like multi-view stereo, sheet of light, or by ready-to-run 3D hardware scanners which are also directly supported by HALCON. The 3D surface comparison evaluates the resulting point cloud with the trained object model.
HALCON’s comprehensive 3D vision features are enhanced and improved by registration and triangulation of point clouds, feature calculation like shape and volume calculation, segmentation of point clouds by cutting planes and many more to detect and process 3D objects. Photometric stereo is improved for special use in surface inspection. Conventional surface inspection will now perform 3D surface inspection so scratches, cracks or dents in surfaces are quickly and easily found by taking shadows into consideration. Feature selection for object/defect classification is now made easy with the new automatic feature selection, giving the ability to optimise a bundle of features quickly and therefore creating a powerful solution in a short time. Lastly, HALCON 11 will now also run on the operating system Mac OS X, entering the Apple world to extend the accessibility of this powerful software package to Mac OS X users.
There is no doubt that once users begin to grasp the possibilities of this latest version of HALCON many new vision application opportunities will be bourne. The Halcon World Tour comes to the UK on 22nd June, register to attend at www.multipix.com/halcon11worldtour
