Advanced 3D industrial inspection system

A Spanish ICT (Information & Communications Technologies) research center offers an inspection system that applies machine vision to quality control. Industrial inspection is a field where accurate and fast systems are important to achieve high quality without compromising the production speed. Today the process of verification of product quality is incomplete or requires mechanical handling, with the associated problems (hiding of some faces, increase of the inspection time, adaptation to each manufactured part, etc.), costs and delays. The 3D industrial inspection system offered proceeds in three simple steps: 1) Capture The device contains a number of cameras distributed in a sphere. The special location of the cameras is optimized to obtain the best reconstruction fidelity. It captures the objects without contact or manipulation, and without hidden surfaces: the part under inspection is dropped from the top, it falls freely and the images are captured simultaneously by all cameras, allowing the fast reconstruction of an accurate 3D model of the object. 2) Reconstruction Once obtained all the images, a 3D reconstruction is performed. The techniques developed for this lead to a very efficient process that allows a very high throughput of the system. 3) Inspection The tolerance is easily adjustable according to the quality parameters defined for each part or for each particular area of it, giving rise to the rejection of those objects that do not fit the required dimensional or surface standards. The analysis of the production problems is made easier with an included application that, using a colour code, highlights the differences between the part and the reference model, allowing visualizing the errors that appear in an object. Different types of errors are shown in the user interface, in function of the kind of analysis performed. Thus, the complete set of results for an inspected object is a report composed with information on surface defect inspection, volumetric defect inspection and a checklist of geometric dimensions and tolerances (based upon GD&T standards). Among the applications of the system, it can be highlighted: industrial inspection for quality control of products of any size, dimensional or surface control, fast acquisition of 3D measurements from real parts, etc., everything with low maintenance costs and high throughput. There are many application sectors for the system such as plastic industry, food industry, packaging, electronics, automotive industry, pharmaceutical industry, … The research organization is mainly looking for industrial equipment manufacturers that can implement the product into industries. Different types of co-operation are possible: license agreement, manufacturing agreement or services agreement. Manufacturing agreement: The Spanish centre will provide the software technology and the prototype to the collaborator, and will keep on improving it and its functionality. The collaborator will manufacture the physical part of the system (hardware). The collaborator will receive a % of the ownership of the final product. License agreement: Once the product is industrialized, a collaborator is needed for the commercialisation and deployment of the system. This collaborator will charge to the client and the Spanish centre will receive a license fee for each deployment of the system. This license, and the potential exclusivity, will be negotiated with the partner, taking into account the market to be addressed. There is the possibility that the manufacture and commercialization is carried out by the same partner. Commercial agreement with technical assistance: If the partner is interested in a specific analysis/inspection of a sample of products, the Spanish centre will perform a feasibility study before any other development/deployment project.
