Project Consultation and Conceptual Design

Mile Stones

Buchanan Systems GmbH is specialized in the solution of complete image processing tasks. Customized to your requirements, we offer choices from component selection right up to the creation of a turnkey complete solution.

Usually in cooperation with the customer the following phases are carried out:

    Phase 1: Analysis of Feasibility

    Firstly, the requirements of the system are being evaluated as well as a coherent solution concept. For this purpose you can send faulty and fault-free objects by mail to us, including the machine sketch. Alternatively you can collect the test objects. We will then collect them from you free of charge as part of an on-site consultation. With them we look for reliable and economical solutions.

    At the end of this phase we will work out a first quotation for better orientation.

    Phase 2: Conceptual Design, Component Selection and detailed Preliminary Investigations

    After the indicative offer corresponded to your ideas, appropriate preliminary examinations are being carried out. This is usually done on base of a technical specification sheet. In simple cases, a written description of the task may be sufficient. A subsequent acceptance is either based on a set of sample parts (limiting sampe / good / bad) or on base of image series.

    Preliminary examinations are necessary, as otherwise the reliability of the systems can be influenced by unforeseen reflections or critical lighting conditions. For this reason, Buchanan Systems GmbH selects the specific components by qualified specialists during a preliminary examination in the laboratory.

    The cost for preliminary examinations depend highly on expenditure. The number of scenarios which need to be examined and the variety of types is crucial for that. A concrete offer for the complete solution can be created after completion of the laboratory examination. In case of order submission, the preliminary examination will be settled as part of the complete project.

    At the end of this phase we will discuss the test principle and the offer with you in detail.

    Phase 3: Launch On-site

    When ordering then we deliver the components and start them up on-site. Image series are initially recorded during the running process in the case of complex projects . These image series are used in the laboratory to prepare the test programs.

    The acceptance process is carried out after the integration of the test programs and error-free communication with the PLC.

    Phase 4: Acceptance

    A set of sample objects is usually checked in test operation during acceptance process. When all inspection objects are correctly assigned then the Final Acceptance will be carried out.

    Buchanan Systems GmbH offers a 2-year warranty.

    Phase 5: Optimization

    The optimization is carried out during ongoing process after the Final Acceptance. Images of faulty (possibly also error-free) objects are stored and analyzed. Test parameters are adapted if necessary.

    Phase 6: Maintenance and Service

    Buchanan Systems GmbH uses exclusively branded products from well-known manufacturers. We offer a fast on-site service for the case that regardless of that something might be wrong.

    Buchanan Systems GmbH offers to realize a remote maintenance for service purposes for a fee for our customers if the technical and company requirements are met.

Frequently Asked Questions

General information

Industrial Image Processing / Machine Vision
Definition: Automatic evaluation of camera images for carrying out test, measurement and control tasks in an industrial environment.

In particular, attempts are being made to automate aspects of human visual intelligence.

Image processing is an important efficiency factor in industrial production whether to support handling processes, quality control during production or final inspection. Industrial image processing provides valuable data for the optimization of production processes, increases profitability and generates competitive advantages!

Depending on the task, different criteria become the central points and a number of factors have to be considered. Only well interaction of all components guarantees success.

Camera Systems

Intelligent Cameras

In an intelligent camera, the image acquisition and evaluation unit are combined in one device. This results in the following advantages:

- Compact design
- Highest image recording frequencies
- Affordable solution for single-camera applications

Multi-camera systems

Multi-camera systems consist of a central evaluation unit and one or more connected cameras. It generally takes different views of test objects. This can take place at the same time, at different times or at different locations.

- Maximum freedom in the composition of the cameras used
- System is easy to expand
- Affordable solution if several cameras are needed

Surface camera

A two-dimensional image is recorded with the aid of a sensor. Area cameras differ in many aspects. (E.g., sensor and pixel size, resolution, sensitivity, noise performance, and monochrome or color sensors as the sensor is shaded and read out after exposure, etc.)

Line camera

A line camera is a camera type which has only one line(s) (line sensor) (sometimes 2 or 3). Although line sensors have approximately the same pixel sizes as area sensors, the line length can be much larger. Instead of the maximum 1-4 k pixel width in area sensors, a line camera can have 17 k pixels or more. Consequently, a line camera provides a better spatial resolution for a given object field. In addition, a line can be read out much faster than a surface.

NIR-Kamera (Near-Infrared)

The region of the near-infrared (NIR) is the region of the electromagnetic spectrum, which directly adjoins the visible region and therefore can no longer be perceived with the human eye. NIR-optimized industrial cameras are especially designed for applications in this wavelength range.

Thermographic Camera

A thermal imaging camera (also called a thermographic, thermal or infrared camera) is an imaging device similar to a conventional camera but receiving infrared radiation. The infrared radiation is in the wavelength range of approximately 0.7 μm to 1000 μm. Thermal imaging cameras, however, use the spectral range of approximately 3.5 to 15 μm (average and long-wave infrared) due to the typical emission wavelengths in the vicinity of the ambient temperature. This range is also suitable for the measurement and visualization of temperatures in the ambient temperature range when the emission level is known. However, this scatters very much between 0.012 and 0.98 depending on the material - correspondingly the temperature assignment can be very inaccurate.

Telecentric Objectives

Telecentric Objectives perform reliable and precise test and measurement tasks. Especially where geometrical reproduction of three-dimensional objects is important.

  • No change in the image scale due to object displacement
  • Minimal Distortion
  • Perspective-free
  • High Image Quality
  • Avoidance of covered Edges

Objects are displayed without perspective. In contrast to the perspective mapping, the spatial assignment of the objects is missing. Therefore, objects with the same dimensions are, even with different distances to the camera displayed in the image at the same size.

The perspective-free illustration enables the display of all components without edge covering. The elements do not obscure each other in the picture.

Entocentric Objectives

Entocentric Objectives are used in attributive testing when objects have to be inspected with regard to certain characteristics. This is due to their perspective mapping properties.

  • Light Weight
  • Small Dimensions
  • Perspective-free
  • Infinitely adjustable and fixed distance adjustment allows the lens to be adjusted to working distance and test area.

The further an object moves away from the camera system, the smaller it is imaged. This corresponds to the perception with the human eye (natural perspective).

The perspective-free image makes it possible to obscure components that are different in height. Not all objects or structures are visible.
