Demanding machine vision tasks require powerful components and many years of know-how in order to realise perfect solutions for the user. To ensure this, we have been successfully using machine vision products from Teledyne DALSA for a wide range of applications for years.

In addition to high-performance products, however, another factor is enormously important for us and our customers: in the event of errors or questions, the manufacturer's support must be available quickly and competently and provide reliable answers, something we have been able to rely on for many years at Teledyne DALSA.

The optimum technology for your tasks

For demanding machine vision applications we rely on components from Teledyne DALSA already for a long time. In close consultation with end users, our specialists develop system solutions tailored to the customers individual tasks, always with focus on finding the best technical and economical solution for the task, to find the best possible combination of components and to integrate the vision system into the equipment so that reliable operation without interrupts and faultless results can be ensured over the entire life cycle, even in applications that run around the clock every day. Teledyne DALSA products have proven themselves very well in this respect in numerous applications.

Inspection of electronic components

In this environment, Teledyne DALSA's Genie camera series has proven itself. These cameras continue to deliver high quality images even at elevated operating temperatures and have a very low failure rate. In the rare cases where failures did occur due to the extreme conditions, Teledyne DALSA was very accommodating and facilitated a quick, unbureaucratic replacement of defective cameras. Another advantage, in addition to the mechanical robustness, are the numerous variants of the Genie camera series, offering a suitable model for almost every conceivable 2D image processing application in terms of available resolutions and interfaces.

In recent years, we have been able to solve numerous tasks in a wide variety of applications in the electronics industry. In the production of electronic components, for example, there exist so-called hot processes in which wafers are coated and the quality of the process must be checked.

Due to difficult production conditions, only industrial cameras that deliver accurate results even in an extended temperature range are suitable for this.

Genie camera series

In addition, the Genie cameras are often used to set up multi-stereo systems, as they can be synchronised very easily and precisely via the Precision Time Protocol (PTP). Based on this standard, the necessity for a trigger cable can be eliminated  and synchronisation takes place exclusively via the network.

Troubleshooting line by line

Linea linescan cameras

In many applications where web goods have to be inspected, line scan cameras have proven to be a more suitable technology than area scan cameras. The images are captured line by line and the image strips are then stitched together to form a theoretically infinitely long image and thus allow the inspection of steel coils, paper rolls or textile webs, etc.

As Teledyne DALSA has been a technology leader in the development and production of line scan cameras for many years, we regularly rely on its unique portfolio, which covers a wide range of resolutions, speeds and interfaces and enables us to select the optimum line scan camera for a wide range of industries and applications.

Three-dimensional inspection

3D image processing has advanced technologically a great deal in recent years and today allows a much simpler solution to many applications that cannot be realised with 2D systems, or only with considerable effort. The technology is now cost-effective, reliable, repeatable, easy to implement and has proven itself in a wide range of demanding applications.

A typical example of a 3D application we have realised is the optical inspection of brake discs for the automotive industry, which enables a better matching of defects than 2D vision systems.

Since brake discs are made of grey cast iron, they can have holes which are only exposed during grinding. These holes on the surfaces must be dimensioned and the depth of the balancing milling measured.

However, inspecting brake discs is not easy due to the lighting situation:

The surfaces are polished and have grinding grooves that are unavoidable during production and create certain artefacts.

To make matters worse, fingerprints or fine-grained sand as a residue of the previous grinding and washing processes are often falsely detected by 2D image processing systems as unacceptable defects.

Multi-camera applications

In many applications, the use of a single camera is not sufficient to check all potential defect features. In such cases, the use of multi-camera systems helps. In this case, two or more cameras inspect the test parts simultaneously from several directions and enable a comprehensive evaluation by comparing the images from all cameras.

The Vicore dual camera system from Teledyne DALSA enables the combination of a wide range of 2D and 3D cameras. With this system, we were able to realise a system at a large European food manufacturer that checks the presence of biscuits, their correct dimensions, the correct browning and their number and distribution on baking lines.

For the realisation of this application, the robustness of the vision system and the possibility of an exact adaptation to all specifications was an important criterion to ensure a trouble-free operation around the clock.

Many years of successful partnership

Teledyne Imaging is the only manufacturer in the industry that develops and produces the sensors for its line scan cameras itself and can therefore optimally adapt them to the customers' ideas. In addition, the product portfolio covers the complete machine vision spectrum. Whether 2D or 3D systems, visible light or other wavelength ranges such as SWIR or UV, single or multi-camera systems, there is always a suitable camera for the respective application.

In-house software development ensures a seamless adaptation of the required software to the hardware. With Sherlock, Inspect and Sapera, several software packages are available that offer users with different image processing knowledge levels extensive possibilities for realising their solution. In addition, the graphical AI training tool Astrocyte provides users with an effective way to simplify the development of vision systems with the help of innovative tools from the field of artificial intelligence.
