Machine Vision for Mechanical and Plant Engineering
The newsletter for the mechanical engineering and plant construction sector, which is published by the journal INSPECT presents several case studies for the improvement of product quality. The following applications are described: - Robots search for earthquake victims- Vision sensor increases productivity for coil roll inspection
- Inspection of solar modules
- Cameras for traffic surveillance and quality control more
Machine Vision for Security
Image processing solutions are increasingly being used in security technology. Several case studies in the security sector newsletter published by the journal INSPECT illustrate how these solutions can be used effectively: - Fair play in Las Vegas- Detecting damage on Finnish roads
- Terrain surveillance from the ground and the air
- Staying safe at night You can find further information and image processing solutions at the Vision, the international image processing exhibition, which will be held in Stuttgart from 8 - 10 November. more
Machine Vision for Food and Beverage
Packaging quality has an enormous influence on the decision to buy. The following applications show how image processing ensures perfect print quality and undamaged packaging. - FireWire cameras inspect food packaging- Inspection systems for bottle caps
- Counting and inspecting beverage packages
- Image processing for high speed manufacturing processes You can find further information and image processing solutions at the Vision, the international image processing exhibition, which will be held in Stuttgart from 8 - 10 November. more
New Class of Camera Systems Simplifies Machine Vision Integration
The use of machine vision solutions is still often severely restricted by the non-trivial integration of individual components. Limited by system integration constraints, these components are no longer capable of performing their full potential. Now, a new class of camera systems - the IVS (Intelligent Vision System) - is to change this situation and to revolutionize machine vision. more
Wherever the Journey Goes
Easier to handle and more compact and powerful: These are the characteristics new camera models should have when introduced to the market. Thereby, the cameras' performance is pushed by the developments in the consumer market. One consequence is the availability of new CMOS sensors with a resolution of 1.3 megapixels and global shutter technology. According to first tests, these sensors exceed the light sensitivity of existing sensors. Does this mean that CCD cameras are now becoming redundant? more
Optical Metrology Basics: Triangulation
Triangulation is a trigonometric method to determine the distance between a reference point and a point of interest by aiming at the target from two different positions. In a so-called triangulation sensor this principle is put into practice and utilized for optical metrology: a laser beam is directed onto a surface at a well-defined angle of incidence, and the spot is picked up at a different angle and imaged onto a detector array. Combined with a scanner or a linear drive, the complete surface of the object may be probed and can be depicted as a point cloud in three-dimensional space. more
Illuminating the Design Process
Up until now the processes of product development, from design to inspection, had been rather "sequential." First the design of the product had to be finished using CAD software. Then by using CAM software the manufacturing had to be planned and evaluated. Finally product developers had to ensure quality by designing a testing station. Now, a newly developed software tool makes it possible to design in the end-of-line control already during the product development process. more
Image Processing Basics: Sensitivity
What is the irradiance needed to produce a camera signal suitable for image processing? What are the maximum and minimum intensities in the brightest and darkest areas of an image, respectively, which will allow for stable algorithms? When tackling these questions, you will immediately realize that a short glance at a data sheet will not settle this case. The article describes some basic concepts which may be helpful for further reading about this complex topic. more- Legal
