Video-Measuring-Software COMEF 4.x


COMEF (COmputer MEssFadenkreuz) - Image processing software


COMEF is an image processing software. The software is used to take over images from microscope cameras into a computer, to transfer live video images at a monitor, for measurement tasks, for an annotation of images with the measuring result and for a saving of the images including all annotations at a computer.


COMEF - Features

 

  • Image acquisition from numerous cameras (analog and digital)
    for live video representation on a computer screen
  • Measurement of distances, angles, areas, circles ...
  • Loading and saving of pictures up to 16 MPixel
  • Particularly suited for measurement of megapixel-images
  • Highly accurate calibration function
  • Highly accurate measuring functions
  • Comfortable lettering of images with measuring marks and -values,
    rulers and texts
  • Creation of freely configurable measuring protocols
    COMEF      

 

  
Since over 20 years the video measuring system COMEF worked satisfactorily as industry-spreading solution for highly exact measuring tasks in many applications. COMEF is characterised by a simple handling, an extremely high measuring accuracy and comfortable documentation possibilities.  
 
 
The software comes wit a basic modul with standard measuring functions and all service options (e.g. Image notification, Image saving, Protocol) and additional (option) modules.  
 

Simply handling

The user surface of COMEF allows an intuitive operation. Without the study by manuals the user can start immediately with the work. Nevertheless a meaningful manual is a component of the scope of supply.

Image sources

Analog and digital cameras can be used as image sources.

Interfaces are:

  • Fire-Wire-cards/boards (over WDM-driver)
  • USB-Bus (for special cameras or over WDM-diver)
  • Twain-Interface

Accuracy starts with calibration

COMEF offers the optimal condition for the highly exact measurement of digital picture information with its sub pixel accurate calibration functions. The calibration can be made alternatively in one or in two dimensions and is very simple despite the high accuracy to accomplish. The calibration data are stored in a calibration data base and can be assigned by keywords clearly to different enlargements or optics.


Easy and comfortable Image documentation

In connection with the comfortable possibilities for the picture inscription with measuring markings, measuring data, rulers and texts COMEF becomes the ideal aid with the picture documentation. The results of measurement can be registered very easily together with the measuring marking into the picture. With COMEF all possibilities of electronic media are open to you.


Taylormade measuring records

 

COMEF - Measuring protocol         

A substantial component of the COMEF basic modul are the freely configurable metrology records. They make it possible to make for different measuring tasks particularly adapted protocol templates to store and again use if necessary immediately. A metrology record can be supplemented after the measurement with free text. In addition, the measured values are to be stored as ASCII file, whereby an interface is given to other applications.

 

 

 


Measuring functions of the basic modul


1. Distance measurement

Measurement of any distances by different measuring modes. The measurement takes place via setting measuring points manually on the monitor. Note! The software processes a function to the automatic edge touching, with which the reproducibility of the measurement can be increased considerably!

 

COMEF - Distance measurement                 COMEF - Distance measurement           The following measuring functions are available:
  • Point to Point
  • Point to Line
  • Point to Circle
  • Line to Circle
  • Circle to Circle

 

2. Angle- and radius measurement

COMEF - Angle measurement          

The measurement takes place via setting measuring points manually on the monitor. Note! The software processes a function to the automatic edge touching, with which the reproducibility of the measurement can be increased considerably! 


3. Length measurement

COMEF - Lenght measurement           Here the length of lines with any form can be measured. The measurement takes place via setting measuring points manually on the monitor. Note! The software possesses a function to the automatic edge touching, with which the reproducibility of the measurement can be increased considerably!


4. Area measurement

COMEF - Area          

The measurement (i.e. the definition of the sample under test) is made by the free choice of the grey tones (0…255). Two trigger thresholds can be defined. Optionally the object with the largest surface area can be recognized automatically as object. Smaller particles within the same grey tone range as the sample under test are automatically ignored by this filter.

 


Option:  Additional software modules


1. Structure width measurement by greyscales


COMEF - Measurement by greyscales          

The width measurement by means of grey tone processing represents an extremely high performance and highly soluble measuring method for linear expanded objects and is available as auxiliary module. It can be used for the distance measurement from edges of all kinds.

That concerns e.g. the measurement the width of circuit paths, the distance and the width of structures on SI-Wafers and photomasks or other edge distances.

During the width measurement does not take place the measurement any longer at the video picture, but on the basis of standardized grey tone distributions, which can be determined by freely selectable object fields. As can be shown easily, with this method the reproducibility can be increased up to pixel/10, which is the classical subpixel-accuracy.


2. Automatic object classification and counting (Blob-Analysis)

COMEF - Object classification

COMEF - Object classification

         

The software module ACCOUNT is able to detect and classify automatically objects in the measuring field. Most frequently a classification is interesting by the size of the surface of the objects.

ACCOUNT is able to determine automatically the number of objects, which belong to the pre-defined size classes. The objects are dyed in the picture according to their class allocation. A protocol is produced automatically.

The size classes are free from the user to define. Other classifiers are possible to define. An operational area is for example the cleanliness analysis of filters.

 

 


3. Automatic ring measurement (O-Ring-Measurement) (Ovality)

COMEF - Automatic ring measurement (Ovality)          

The auxiliary module Ring Measurement serves the smallest and largest wall thickness of rings and tubes for the automatic measurement. Simultaneous the largest (Dmax) and the smallest (Dmin) outside diameter is measured. Oval shape results from Oval = (Dmax – Dmin). The software module works highly exact with grey tone algorithms.

The measuring functions are expandable, for example on the automatic measurement of the internal diameter. Other special software modules can be developed on customer request.
